Ethanol From Waste Straw 449
phcrack writes "The CBC is reporting that 'Iogen Corporation of Ottawa has developed enzymes to break down waste straw and wood chips into ethanol on a commercial scale.' Apparently traditional ethanol from food crops like corn used at least as much energy to create as they released when burned. It's nice to see that big oil companies are helping fund a project like this too. It's very rare today to hear of a major company throwing money at a research project since the '80s."

Ethanol is only a smart business because it is subsidized (like oil, but that is another story). The only smart energy business is that in which net positive energy can be attained. That is, the product will produce more energy than it takes to manufacture it. Out of all forms of synthetic energy, wind, hydroelectric and some solar types will produce net positive energy.
We need to use what is left of our non-renewable fossil fuel supplies to build these replacement supplies. Unfortunately, these all generate electricity and there is no current method of storing electricity with the density of current oil-based products. We'll need some of that energy to develop hydrogen and electrical storage.
Water is a remarkable battery if we could manufacture a fuel cell affordably (i.e. - out of non-noble metals like platinum). Just add electricity and you've got H2 and O. Lovely.

Yeah, generally I view this sort of thing with skepticism. But if you take a look at Iogen's website, you'll see that they can take 1 ton of cellulose-rich farm waste and turn it into about 300L of ethanol.
Not only could you have a hell of a party with that, but there are other possibilities.
They can use wood chips. So, probably paper too. I'm sure there's a fairly large waste stream from paper recycling, of paper and pulp which can't be used to make new paper. How about tree bark? How about compostable waste from the garbage? Maybe even cotton fibers?
This is a *massive* quantity of raw material which is all waste anyway. And all of it is plant-derived, so consuming it as fuel causes no net increase in CO2.
All they need to do is not tax the fuel, and you've instantly provided cost competitiveness and a powerful incentive to convert your vehicle (if it isn't already ready for it).
I read that there's an ethanol/methanol gas station here in Ottawa, but they're for the federal government vehicles. It's just down the street from me, in fact. I'm a federal government employee, I wonder if I can fill up my personal vehicles there?
My 1976 Dodge Ram has an aftermarket fuel pump on it. The fuel pump is a high-volume unit, designed for drag racing, and I put it on because it was cheaper than an original replacement part (more competition in the aftermarket). But it's rated for 100% methanol. The carburetor, which I rebuilt soon after I bought the truck in 1999, has a brass float - also safe for methanol. I replaced the rubber body-to-engine fuel line at the same time as the fuel pump; it's also safe for methanol.
In short, I can fill up my Ram with ethanol or methanol. If the cost is competitive, I'll happily throw a vacuum gauge on it and adjust the timing and mixture for the new fuel.
The old big-block, with bores the size of paint cans, really won't care what the fuel is as long as it pushes the pistons back down at the right times.

Isn't that the same as solar cells, given that they require massive amounts of energy to make, output feeble amounts of energy on a per-cell basis (and at most 0.707 of that is harnessable as alternating current), and have a finite lifespan (primarily to cracking caused by heating/cooling cycles)?
Actually, ethanol/methanol is a great step toward solar-powered cars; capture the solar energy with plants, store it as chemical energy, release it as heat energy within an internal combustion engine. Of course, one could argue that this is already what happens when you start up your Hummer.
Enthanol/methanol are a far better automotive fuel than electricity, so if this replaces the (misguided) efforts to produce electric cars, that would be excellent. It's still effectively zero emissions, since every CO2 molecule which comes out of the car's tailpipe was already scrubbed from the atmosphere when the plant was growing. There will still be NOx and unburnt HC, as there are with conventional cars, but neither one of those species is chemically stable in our atmosphere and both are rendered back to N2, CO2 and H2O very quickly.
I have two big worries with electric cars. The biggest being the batteries - by necessity, the greater the energy density of the battery, the nastier the chemicals inside it have to be. Weird things happen to cars - accidents, ditched in lakes, etc. - so it doesn't seem like a good idea to be carrying around hazmats which make gasoline look benign. The other great worry is that electric cars all must be recharged somewhere - how many new nuclear and coal power plants will have to be built to keep all these electric cars recharged?
Transition would be easy, too - as soon as the fuel is economically feasible, gas stations can start dedicating a pump or two to it. Many modern vehicles are already built to run on methanol - Chrysler experimenting with "Flexifuel" Plymouth Acclaims and Dodge Spirits as far back as 1992. And with a little bit of work - swapping old rubber-diaphragm fuel pumps then doing standard tune-up stuff like adjusting the mixture and the timing - just about any antique vehicle will run happily on the stuff. The hardest converts will probably be 1980s EFI cars.... and diesels.

Their output is also convertible to AC at 90+% efficiency, using modern inverters. Where'd you get this sqrt(.5) nonsense?
The problem is efficiency. There are many more losses with the conversion to plant matter and back, so you need a lot more capture area. As long as you're effectively getting it for free (as a byproduct of something you're growing anyway) you're fine, but if you have to pay for the acreage with the fuel production alone your costs just went through the roof. Speaking of roofs, the average house's roof can capture more than enough sunlight to power the average household's daily driving even if you're only using solar cells. If you assume 340 WH/mile [epri.com] and 20 miles/vehicle/day, you need 6.8 KWH/vehicle/day. If you get good sunlight for 6 hours/day, you need a bit over 1 KW(peak) of solar panels to supply this. At 10% efficiency this is only about 10-14 square meters of roof. Your typical ranch house has upwards of 100 square meters of roof.
You're half right.
The optimal solution for current (cheap) batteries is the plug-in hybrid [iags.org]; the batteries store power for short trips and surge acceleration, and the sustainer engine burns fuel for longer trips. The efficiency of such a vehicle can easily be twice that of a non-hybrid. I recall seeing a figure of 17% which works with other calculations I've done, but Chevron has published a figure claiming that the average is closer to 12%. That's probably where your Ram is hovering around.

Most media outlets aren't willing to say anything positive about capitalism, it undermines their agenda.

No, the reason the media don't report it isn't their 'hatred of capitalism', it's because it isn't sensational enough. Bad things are sensational, whether it's US troops being shot up, princesses dying in Parisian road tunnels, or Democrat presidents playing around with interns. Companies investing money into research isn't news, it's business. Results get reported in the business news, they only reach the main news either when it goes wrong, or the

This is fantastic if it reduces the cost of ethanol production, and allows it to be produced from straw that is currently just burned. But it won't make the gas industry obsolete.

Yes, I really do, and I think you are naive for suggesting otherwise.
Contrary to what may be suggested by the moniker "Big Oil," there are several oil companies. They compete with one another.
The oil business is a difficult one to compete in. Ever wonder why Exxon bought out Mobil (to form what was for several years the largest company in the world?), BP bought out Amoco, etc? Economies of scale. It's nearly impossible to run a petroleum company and make any money unless you are HUGE. Profit margins are very tight. It's a mature business. You can't come up with a special widget, form a 1 man company, and be successful selling it to a niche market overlooked by big companies. Gasoline is gasoline is gasoline.
Oil majors are broken up into an upstream business, a refining business, and a petrochemicals business. One of the reasons this is done is to smooth out gains and losses associated with fluctuating oil prices which oil companies themselves don't control nearly as much as OPEC. When oil prices are high (supply is artificially low b/c of OPEC control), the upstream and refining businesses make money. However, petrochemicals suffers because the feedstocks to petrochemical processes are refined petroleum. When prices are low, the upstream and refining businesses suffer, but petrochemicals does well.
It just so happens that you and I are direct consumers of a big chunk of refined petroleum, namely gasoline. We are not direct consumers of petrochemical feedstocks (you don't go to Wal-Mart and buy a cylinder of ethylene or benzene). So unless you have been involved in the business, you know only half the story.
It's a dumb thing to complain about, in any event. The price of gasoline over the past 20 years or so has actually risen less than inflation.

I've got two questions for you.
If gasoline were completely replaced by ethanol, what companies would be positioned best in the market to distribute it, deliver it, and sell it? What companies would own a massive fleet of tanker trucks, miles and miles of pipelines, storage tanks and distribution centers, and hundreds of thousands of facilities with underground storage tank
