      Eventually, when auto technology becomes perfectly tuned to the environment, there will be holes in the floor and you will be both driving and steering with your feet. So rest assured, your idea is being worked on.

My first thought when I first saw GM's vehical is what happens when I'm crusing down the street then reach to change the radio station? I stop accelerating? Let's just hope that they find a way to get the costs down and then remember to sell it to us in the US.

      Yeah, I really don't like the interface in the prototype. Fortunately, it's skinnable also. So you can have a car with pedals. Part of the review says that it'll be a better car without pedals because the steering wheel will have a better range of motion. However, if you are handicapped and missing legs or something this would provide a great deal of independence I'd think.

      I was pretty impressed with the performance specs. 97+ MPH out of 130ish horespower is not bad. When they can pull 200 HP out of it and have 4 wheel drive (more for safe delivery of power than offroad, think Audi Quattro not Land Rover) and you'll have something I'll want to buy. Oh, and 250-300 mile range would be good also.

      Begs the question of "how do you measure fuel economy". MPG (or L/100Km) is a bit off, unless you measure the capacity at STP. I think we need to go to a straightforward percentage (how many joules were liberated and how much forward momentum/sec was generated).

      • "97+ MPH out of 130ish horespower is not bad."

        Uh, yeah it is. Honda's been making cars that'll do 120mph with less than 90hp for decades. 97mph is a joke. Then again, I've never fully understood why cars in the US can go 120mph which is double the old national speed limit.

          Because infernal combustion engines and their associated machinery like gearboxes aren't efficient when run near the upper or lower limits of their capability, but in the middle. Upper is defined here as maximum rpm, not torque (which occurs closer to the middle rpm), and lower is the idle rpm. Car gearboxes aren't like aero engines; there is a direct relationship between engine rpm and wheel rpm via the gearbox.

          If you want a car that runs well at 60mph, you have to built one that peaks at 120.

          Yes, but the honda weighs a lot less. Keep in mind, this thing's the size of a Cadillac DeVille, not a shoebox Honda. Serious room for 5 full sized passengers. And it's a constant torque curve, so it'll accelerate like crazy (which is really the reason I want the 4WD). Internal combustion engines generate torque (and HP) as their RPM's increase. Fuel cells use electric motors, which have the same torque at 10 RPM as they do at 10,000 RPM.

          To turn your argument around, I've got a 1 HP engine in a radio controlled car, and it'll do 60. Some others will do 85 with not much more power. So Honda's not living up to that standard! How dare they produce inefficient cars that take 90 HP to get to 120 MPH.

            Well that's all up to the transmission, displacement, and a few other factors. Most cars generate peak torque low in the rpm range and higher horsepower as the rpms increase. Nearly every VTEC equipped Honda will generate peak torque around 3000-3500 rpms, while the peak hp comes at redline in each gear. On the other hand, your garden variety Subaru Impreza WRX generates peak torque at a low low 2200rpm, and peak hp near 6000rpm.

            At any rate, comparing rc cars to full sized vehicles is just a ruse. Thanks for the insight.

    • by Anonymous Coward
      Let's ignore the obvious problems inherent in this design (brake/accelerator location) due to going against the driver's intuition and previous experience. They were just trying to catch the eye by making some oddball design choices.

      Engineering-wise, this has some impressive shit inside, if not entirely innovative. It's certainly a noteworthy achievment. Sure, it's really not that cutting edge, instead it's just an aggregation and refinement of stuff that's been done already.

      I'm sure I'm in the minority here (and will be modded down for it, of course), but here goes...

      Does anyone else miss real cars? Aren't you sick of these underpowered, jellybean-looking, rice-burning, gook specials out there? Do all the new electrics and hybrids need to go down the same path?

      Don't you miss that 2-tons of Detroit steel, the kind of car that can register on the Richter scale on ignition?

      Why does the vision of the future have to be so passified? Why can't it be kind of rugged? I'd feel pretty damned fruity (ala Ed Begly Jr) driving around in one of these plastic-turds.

      So, yes, I'll give them some credit for the engineering. And, yes, it's a somewhat noble cause. But, can't these designs still be fun? Why do they all have to conform to some worn-out template of how a car of the future should look? C'mon, just a little creativity and passion would be appreciated... stupid fuckwads.

      Who wants to bet there's a pointy-haired manager responsible for the aesthetics (probably the one that gave the quote in the parent post)? The conversation probably sounded something like this:

      Designer - "Here's our new electric vehicle."
      Management-Jerkoff - "But... that looks like a regular car."
      Designer - "Um, well, yeah... we didn't want to alienate our customers."
      Management-Jerkoff - "But, how will anyone know it's electric if it looks like just any other car?"

      Don't they realize, if these things didn't stick out so much, they'd sell more? Most people don't want to look like a dork in one of these (yes, /.ers do want to look like that, but most "normal" people don't). I'd love an electric that could capture the look & feel of a 1972 Mach 1 Mustang (constructed in 1971, of course) or a nice old GTO (not a big fan of the Judge though), I would miss the sound on an electric though.

      There's a very heavy user interaction (look & feel) component that goes into choosing a car. These companies insist on alienating their consumers from the hybrid/electric market by making their cars look rather goofy. They're futuristic, but goofy nonetheless.
      • I would miss the sound on an electric though.

        You know, maybe they'll have a "sounds like a real car" option too... And you'd be able to download different soundpacks depending if you want it to sound like anything from a Model T to a commercial jetliner... shouldn't be that difficult to gauge what's happening on those wires and play/tweak the correct sounds.

        No. Not everyone finds American classic cars attractive. I myself find none of the American classics nice looking, with the possible exception of the original (underpowered) Corvette. It's all the more sobering to know what hunks of garbage they were in anything but straight-line drags, ridiculously humongous horsepower notwithstanding.

        No, I don't miss those 2-ton Detroit steel barges. Mainly because they don't handle, but also because they're criminally inefficient.

        About the looks: this isn't the only concept car that's come out of Detroit recently. There were several that should be more to your liking. The Ford 'Tonka' pickup, for example (even more monstrous than current offerings), Dodge had another 'full size' pickup, and they were both shown with alternative propulsion (the Ford was Diesel-electric, and the Dodge used LNG, IIRC).

        The HyWire mainly looks goofy because it can. It's not only a hydrogen-power prototype, it shows off an entirely different way of building cars. Why stick that underneath some bog-standard undistinctive bodyshell?

        Once this technology goes mainstream, you can bet there'll be body styles to suit everyone.

      While I'm pretty sure you're kidding there are a few reasons to do this onthe HyWire car specifically.

      First, the controls are really different, twist = acceleration, squeeze = brake. Not terribly different from motorcycle controls when you think about it.

      Second, this is probably not going ot turn into a production vehicle. It is sort of a meta-concept car. The fuel cell stuff is all squished into an eleven inch slab centered roughly at the wheel axes. Basically, less the controls, the everything useful but the passengers fits into this tiny space. Next they bolt a bunch of random stuff onto the top. It allows them to design a bunch of body plans without having to remake or remount the engine every time they come up with a new body concept.

      The weird controls probably evolved out of this in a way, they wanted a interface module that could be removed easily. Pedals, because of their location relative to the slab thingy would require a commitment on their part as to where a lot of stuff would go. This way they can play around with configuration to their hearts content.

      Not entirely unlike a 'skinnable' car when you think about it. I think it would be kinda neat to see in a production car, modular form like this. You go in, choose a chasis power rating or something, then choose a bunch of options (two, three, four, or six seats, truck bed, trunk, seats that recline all the way back, sporty aerodynamics, maximum cargo space, driver seat with a high field of view etc). Then you leave for a few hours while they bolt the thing together. Okay, maybe not, but, it's an interesting concept. Imagine, instead of renting a truck for the weekend to move, you go down to the dealership and rent a truck bed, they hold onto your rear seats until you come back.

      As far as the completely transparent front design, I imagine that takes some getting used to, what with the road being that much more obvious as it streams past you.

    Part of the reason these hybrid cars aren't taking off in some circles is because, quite frankly, they look retarded.
    People don't want a car that looks like a bubble with three wheels or controls in places they're not accustomed to.
    People just want a car! Plain and simple. Most people don't care what is under the hood as long as the car is familiar(controls where they should be, etc..) and they can fuel up anywhere. Cars are meant for convenience as far as most people are concerned. Despite what really bad Sci-fi movies would have you believe, the 21st century just isn't ready for some of these new radical concept designs.

    Push the joy stick forward to accelerate, pull it back to brake, lean it left and right to steer. The trigger is the emergency brake, and the thumb button turns your car back upright when you roll it.

    • Nah. Since there are no hydrogen wells, or really any natural source of hydrogen in quantity, it's going to have to be artificially produced. Which requires power. Lots of it, in fact. Which will likely come mostly from the usual suspects: oil, NG, coal, etc.

    As hybrid vehicles go, the Gas/Electric hybrids like Toyota's Prius are cool. They also feel like you're driving a cardboard box.

    Diesel has made much more progress in the past few years as far as an efficient fuel than gas. Try on the Turbo-charged VW Diesel Jetta for a great drive w/ superb miles to the gallon.

    A marriage between these technologies is a great deal for the auto industry, the environment and everything else. The one question is $.

    It sounds like the car is fueled by hydrogen. People won't buy the cars until they can get hydrogen fuel at nearly every corner gas station. Nobody want's to travel a long way to buy gas, or worse, find themselves low on gas 100 miles from the nearest hydrogen station.

    The gas stations will not invest in the eqipment to dispense hydrogen until there's a large number of the cars on the road that can use it.

    And more importantly, where's the hydrogen-distributing power stations? And even more importantly, where's the cheap and plentiful hydrogen production mechanism?

    Hydrogen hybrid cars are all well and nice, but they don't get us anywhere. At the moment the only ways to produce hydrogen are expensive and inefficient, and end up costing more "regular" energy (usually provided by fossil fuels or nuclear power) to produce. Electrolysis is good to play with in the physics labs at school, but when it comes to produce very large quantities of Hydrogen for mass consumption it's worth practically zero.

    I read a while ago in New Scientist that some group in Japan was trying to use a solar-pumped laser in a satellite to convert large quantities of salt water (in a big tank on an island) with an added catalyst, into hydrogen. That's the sort of news which are worth noting when it comes to cleaner fuels. Once hydrogen is available in every gas station, oil will die off naturally. Until hydrogen can be produced cheaply and in very large quantities, there's not going to be hydrogen in gas stations, and all these hybrid efforts are just lip service to make Sunday Ecologists feel better about themselves, so presenting this sort of news as a notable even in the move towards cleaner fuels is like saying "Microsoft issues a new patch for IIS, saves the internet from script kiddies".

      I got into the most ridiculous argument over the weekend with a flaky chick who fancies herself a savior of the earth. She got into a rant about how I should feel ashamed that I use oil to heat my house, burning it and creating pollution, while she has an electric furnace.

      Eventually I gave up trying to explain how all her electric system does is centralize the source of pollution to the power plant. She seemed oblivious to the fact that millions of tons of coal go up in smoke to make that electricity.

      I didn't even bother to bring up the fact that my furnace is much more efficient, and that all the work and money I put into upgrading my homes insulation over the last year means that the furnace fires up for at most an hour or two a day.

      She probably would have gone through the roof if I told her I planned on removing the 2 electric water heaters in place now, replacing with one larger oil-fired heater.

      Sure, she's a flake. But there are plenty of flakes out there, ready to hop behind the wheel of a brand new hydrogen car, completely oblivious to how much energy it actually takes to drive. All they understand is 'steam comes out instead of smoke so it's saving the planet!'.

    I must say, this looks pretty snazzy. Assuming it would hold up in a crash (which, I'm sure, will be addressed). With the suicide-hinge rear doors [akamai.net], some impressive engineering will have to go into making this crash-worthy. (Why do you think they call them "suicide doors"?)

    • If you look closely at the rear doors, though, they appear to have an inside tab that sticks forward to the front door - you can't open the rear doors without opening the front first.

      That doesn't completely remove the problems with that design, but it does make some inroads.
  • Assuming that energy has to be expended to produce hydrogen in the first place, does anyone have any idea on what the net environmental effect of a fuel cell car is versus a traditional ICE one?

    Obviously, there are economies of scale in producing hydrogen in mass quantities, but it seems to me the claims that GM has made to the effect of removing the car as a significant factor in the environment are utter horsehockey.

      I am not an expert on fuel cells or hydrogen, but it is a viable alternative. Fuel cells are steadily increasing in wattage and will soon reach the 200Kw range. Now all fuel cells use hydrogen. The question is where does it come from. The 3 most common ways are compressed gas as was used in the article, gasoline, and methanol. Methanol and Gasoline both require a reformer to break the hydrocarbon chain an mahe H. Gasoline is a complex hydrocarbon, has an excelent energy density, but is complicated to reform than methanol. It is also supported by a large infrastructure. Methanol is a simple hydrocarbon that is easily reformed into H. It has approximately .5x the energy density of gasoline. One very large benefit is that it can be generated from local renewable resources. Anyway the H is made, there will be side efects. Reforming does produce carbon as waste. It can be captured as a liquid or solid rather than a greenhouse emission. Methanol from plant byproducts has all of the nasty issues of industrial farming. As a side note: Why is that vehiclo so damn ugly. There are some very exciting EV prototypes out there. At least one does 0 to 60 in 3 seconds.
    • Don't forget to lump Ford, DC, Toyota, Honda, and Nissan in there with your horsepucky. All are testing and pushing Hydrogen Fuel Cells as an answer to the problems of the internal combustion engine.
  • Wow. Over 100 years of automotive technology and this is as far as we've come. The damn thing *still* can't fly. For me that's the greatest drawback to driving on the road: other drivers on the road at the same time. Fortunately we have lots of roads here that a car like that will never get on. And no, flying for most people is not an alternative, considering how many crash at slow speeds in excellent visibility. Hey, how about a car that drives itself? Take the weakest and most insecure component out of the loop.

      We're still years and years away from that. You'd need to refine radar resolution and control down to a few inches at the most.
      A car that drives itself on an empty road is not too hard. Put it out on the chaotic streets, and you'd have to make it be able to avoid a dog AND a soccer ball at the same time. Without hitting the telephone pole.
      Or have it make the decision...Soccer ball + kid or dog. You want a computer to recognise and decide that?
  • Gm states that you can tune your car to your specifications (handling, braking, etc) by loading a new program... People can barely drive as it is, is this REALLY a good idea? Of course, I would LOVE something like this. Then again, I also get the humor in the commercial that goes "Jim I think I fried the motherboard and the fatherboard too." And contrary to what you all are posting, I really like the futuristic look of this car... really cool. The freedom of vision is unprecedented. Just dont make it tooo customizeable. Crash your computer, oh well, crash your car... ::shrugs::
  • Um, excuse me? I _like_ using my feet for gas and brakes. I don't really want to be doing that with my hands. If the car is supposed to be so modular, are they going to have an optional pedal package for those of us who prefer it?

    The AUTONOMY design is just about the most radical thing to happen to cars since Ford. Especially considering that it comes from GM, who is not exactly known for their forward thinking.

    I've been following this thing from some time.

    Quick points:
    - You can't really 'skin' it. Yes, the shells are interchangeable, but at the factory. A home user bolting on one of these in his/her garage is opening up all sorts of safety concerns.
    - Yeah, it's Hydrogen, but it's not gonna blow up. Certainly not as dangerous as the tank of gas in your car. Go read the Wired article if you want details. It's not a rolling Hindenberg.
    - The wheels can pivot in any direction, which is why the steering is different. No more parallel-parking mishaps, hopefully.
    - They are still more expensive than regular cars, price- and energy-wise, but the trend is looking quite hopeful.
    - The space-savings inside the car itself are remarkable, and allow for all sorts of kooky things, such as a floor-to-ceiling windshield. (how weird would that be on the highway?)
    - The HyWire is a concept. They won't all be 'ugly'. The whole thing is still a good 10 years away.

    GM has gone on the record saying that, because of the elimination of most of the moving parts, these cars could realistically last 20 years. Which is a big concern for GM, obviously having a 20-year-turnover on cars is going to nail their bottom line... until you figure in the savings on engine parts, assembly lines for those engine parts, etc. Suddenly the AUTONOMY is a lot more attractive, as they might eventually cost a fraction of what regular cars do. GM recoups the lost turnover sales from the other 80% of the planet who can now afford a vehicle. And we get cool pivoting space-cars that cost $5000 and go for 2 decades.

    • were still waiting for a good looking skinMark Mainville do you hear me?
    • EX-SQUEZE ME?! Yeah it's hydrogen but it's not as dangerous as the tank of gas in your car?? The article makes reference to a 10,000 PSI "tank" for this stuff.

Of COURSE, they'll have to run a diagnostic before skinning, and suggest fixes for any problems they find...

    Hydrogen is not the magic answer to the world's energy problems. It is difficult and ineeficient to produce, transport, and store it. Just because the end product of a hydrogen+oxygen reaction is heat and water vapor doesn't make it a cure-all for energy woes.

    Hydrogen is just taking energy from one source and storing it for release by something else later, you're time shifting energy. Hydrogen like gasoline and lead-acid batteries is just an energy carrier. Unlike gasoline where the energy has been put there by millions of years of microbial activity on organic material, we have to put energy into hydrogen ourselves. The only clean way to do so is with renewable HSW (hydro/solar/wind) sources. All of these methods of energy capture are horribly inefficient, they only collect a fraction of the energy they are presented with. Cracking the hydrogen out of water takes a bit of energy, as much as you end up getting back out of the hydrogen - minus of course the losses to heat and other inefficiencies in the system. So you have inefficient energy production at one end used to power a transportation system filled with inefficiencies to power ICE autombiles that are replacing energy dense gasoline with hydrogen. Please.

    Fuel cells are much better uses of hydrogen but they still suffer from the same problems as hydrogen ICEs, the hydrogen's generation, storage, and transport. Liquid hydrogen is ridiculously expensive for use in cars or small applications. Metal hydrides like LiBH4 + 4H2O and LaNi5H6 are heavy for the amount of power they can store per volume. A liter of LaNi5H6 has about 3.3kwh in it but weighs almost nine kilograms or four pounds. So you're left with at least for the time being, organic hydrogen containers like decalin and methanol. These of course emit carbon byproducts when cracked so they are no-nos to environuts despite they only release the amount of carbon they pulled out of the environment to produce.

    I'd rather see high temperature superconductors be given a bit more funding along with hydrogen extraction research. If you can get power to my house with very little loss, centralized production systems can produce less power at peak demand. I can also store that energy by cracking water and storing the hydrogen at my house for use in my fuel cell at night or to put into my car. Let the wire transport the energy for most of the trip and let me pump it and water into a refrigerator sized appliance in my garage to make hydrogen for me to use elsewhere. This works well for solar and wind power because it is difficult to make them constant power sources, every house storing its own energy would mean if power output dropped nobody is going to really notice.

    Any new system that requires a radically different and naturally expensive infrastructure to support it is not going to be accepted very quickly. Oil is important to the world because it is cheap and gives them the power they want and need. There's better ideas but until you can engineer them to be drop-in replacements for oil based systems they are a no go. I'd think slashdorks would realize this, until Linux is a drop-in replacement for Windows it is not going to take over the world. You can't just beat a new paradigm or lifestyle into someone and expect everything to work. If you're introducing something new it has to work with systems that currently exist.

    On the flipside to that however, people need to realize their Earth Raper 4000 SUV is a bit ridiculous. For most uses a 100 watt light bulb is overkill. better insulation in your home will cost more initially but give you some pretty good long term savings while at the same time making for less polution overall. People in first world nations need to figure out how to disseminate clean technologies to third world nations that are just developing industrial bases. A currently developing country shouldn't have to go through the smokey coal powered industrial revolution to come up to par with more modern nations.

    The Sun would have a billion years sliced off its lifespan if everyone on the planet used as much energy as people in the US and Europe do. Drop-in replacements are needed to make their energy usage cleaner but also to make them use less energy. You don't need four televisions but if you do have them and want them it'd help if they used as much power as a single old television used. A computer in every room would be cool if they used about as much power as a leaky cable box.

    Hopefully some day.

    Alot of people have raised the point on here that big oil here in America is going to go nuts over hydrogen fuel cell cars. And, of course, it would seem like, since they have insane amounts of money for lobbyists and campaign contributions, they'll win. But they won't, and heres why.


    First we'll start with the military. One of the biggest pains in the ass about any military campaign is supply lines. Keeping supplies going into combat zones is obviously vital, and the only thing thats more of a pain in the ass to get to a mechanized unit, for example, after ordinance is fuel. Tanks, APCs, helicopters, etc., eat up insane amounts of fuel, so the sheer mass of the fuel that has to be supplied is ungodly. However, since hydrogen, as a gas, is compressible, one fuel truck would be able to do the work of dozens, whereas before the lines of tanker trucks could stretch for miles. This means more leeway for tactics, as well as more secure operations, not to mention massive savings in cash and manpower. So of course it'll give the government a hard on.


    Secondly, look at the effect this will have at home. Right now America is enjoying the highest gas prices since the fuel crisis we had back in the day, think it was the 70s. And, unlike most countries, America relies far more on automobiles than countries that actually took the time and energy to develop a working mass-transit system. Its common here for families to own one car, if not more, for every person who can drive, and then we also have massive fleets of tractor trailers and whatnot as well. On the other hand, my friends in England and Germany own typically one car per family, and my friends in Germany, who live in one of the larger cities, simply keep that one in storage, since they never use it. So, likewise, what
    Americans normally use in gas is far more than other industrialized countries,


    With the advent of hydrogen fuel cell cars, for which the fueling stations are really pretty simple, the cost savings alone will be absolutely staggering. If you want to seem an economic BOOM, wait til that happens. Sure, oil companies will lose something like 80% of their business, but screw em, they've screwed us long enough. Once we get to the point where hydrogen fuel cells are common in not just cars but planes, large body vehicles, and industrial equipment, profit margins for shipping companies, airlines, and construction and development companies will go throughthe roof, since probably upwards 30% of their costs will go down. And, since consumers will know this, they will eventually demand costs be lowered, which means the cheaper something is to provide,the more profit you can make as a seller, even if you lower the price, and the more money you can save as a buyer. Boom. Also, we can say "Screw you Middle East, and F off OPEC!!!" Because, hey, what do we really need the OPEC countries for then? Some experts are predicting that once everything is fully implemented, we'll be able to supply our oil needs out of texas and alaska alone. So right there is another eason the government would love this, no matter how much money is being tossed their way, because they've no longer at the whim of OPEC.

    All this potential economic magic, because hey, its government, its all about money, will leave the goverment no choice but to make it legally required that such a technology be fully supported, kinda like broadcasters have to be high-definition compliant in like a year or two I think. And, as for big oil, if they're smart, they'll start plans on developing an infastructure to be the fuel suppliers for this new breed of industry, so it won't hurt as bad.


    Sorry this post is so long, but I've been really hyped up about these things since I read an article in Discover magazine about their development over four years ago. Crazy its finally happening.

    The nerve center of Hy-wire?s electrical system is a single docking port or connection, which provides the electrical connection between the all-aluminum chassis and the fiberglass body. Because it uses fully electronic linkages and controls, the by-wire system simply plugs into the docking connection on the Hy-wire chassis.

    For those of us who haven't figured this out yet.

    Obviously, hydrogen is not an energy source when used in a fuel cell. That is not its purpose. Its purpose is to be a replacement for gasoline. Gasoline is not an energy source in the same way hydrogen isn't. Gasoline is millions of years of stored solar energy.

    It took millions of years to create the raw materials we use to make gasoline. Once we run out (and we will run out - we are taking it out faster than nature puts it back - it's just a question of when) we will have to either make more gas ourselves or split water to make hydrogen. There's no special difficulty hydrogen presents in this regard - anything we use to run cars is going to be in the end an energy storage device, unless we have nuclear/solar powered cars. Both are impractical, for different reasons. So we have two problems in the future - generate power to replace the huge stored supplys we current are tapping, and store it for use in automobiles.

    People seem to assume hydrogen is being proposed as a power generator. FALSE. Hydrogen is being proposed as a way to store energy for use in cars, which can't generate power on site in most cases. Gas is stored power - so is hydrogen when used in a fuel cell. We can't practically create gasoline ourselves - it's much easier to split water and recover the hydrogen. Plus fuel cells are extremely clean and don't give us the byproducts gasoline does. An extra benefit.

    That leaves the question of where to get the power to drive this system. That's a completely separate problem, and one of the most crucial. Solar and wind are the two major untapped as far as non-nuclear power goes. Nuclear isn't practical in the us IN ITS CURRENT FORM. Fusion power is under development, and if a power producing fusion plant can ever be created, that will provide lots of power with byproducts that decay in hundreds of years, not tens of thousands. That may be managable. Otherwise, we will have to adjust ourselves to run on only what power we can recover from solar and wind.

    It's never popular to say it politically, but we can in fact do a great deal to lower our power consumption. Better consumer habits, more efficient homes and utilities, smaller cars, etc. etc. etc. If we can't solve fusion, the cost of power will force this change to take place. It's not an argument of "we shouldn't develop renewables and hydrogen because they can't deliever our current level of power." Sorry folks, it doesn't work like that. Our current level of power generation is unsustainable unless we shift almost totally to nuclear power. Peroid. We don't know exactly how long it will last, but it WILL come to an end. What is up to us is how we cope with it. I'd rather be prepared with the best we can do in alternatives. Hydrogen might allow us to run cars after we can no longer produce gasoline cheaply. Plus it's a cleaner system when the source power is produced from clean sources. It doesn't provide gluttonous power, true, but it might allow us to sustain the worthwhile parts of our lifestyle. That's why this is a development to be cheered on.

Let's organize this thing and take all the fun out of it.

Working...
