Space Power

Public Discussion Opened on Space Solar Power 195

eldavojohn writes "The National Security Space Office (NSSO), an office of the DoD, has taken a novel approach to a study they are doing on space based solar power. They've opened a public forum for it and are interested in anyone and everyone's expertise, experience and ideas on the best means to harvest energy in space. I suppose this is similar to the DoD's $1 million for an energy pack just without the award. Still, if you want to have an influence on the US's plans in space, this would be an easy armchair place to start. Space.com also has more on the details."

    best means to harvest energy in space
    First figure out if there is an efficient way to bring this energy back to earth...

    Cheers!

    >>But, quite frankly, I'd rather see humanity burn in flames than see the Americans in possession of the technology.

    U-S-A #1! U-S-A #1! U-S-A #1!

    Actually, the US would probably be pretty isolationist now if energy wasn't a concern.

    With the internet age of mass communication and cros-pollination of ideas, we are seeing the dawning of the democratization of science. Science, like religion before it, has enclosed itself within walls beyond public scrutiny. This age-old incestuous practice is in the process of changing before your very eyes. I hope we see more experiments like this in the future.


    Really? You must never have gone to a (public) university library. Plenty of science there for one to scrutinize. One just has to get off one's duff and look for it, rather than expect that it will be delivered to them for no effort.

    Yeah, sure, except for that little thing called 'prior art'.

    This is actually the exact opposite of what you say. By designing something in an open, public forum, where all can see the process, we ensure that it CAN'T be patent hi-jacked...or at least, if a patent is granted, it can very easily be contested.

    The whole intent of patents was to reduce the amount of secrecy out there to allow ideas to grow into new and better ideas instead of being locked away in some back room.

    This represents an extraordinarilly expensive solution to a non-existent problem. We already have access to cheap, clean, and reliable power production facilities right here on Earth. It's called nuclear power.

    The traditional way to think about it is 'beaming' energy back to earth in some fashion (microwaves? laser? etc). But another way to harvest energy is to use it to refine resources in space ... use the energy to harvest or refine near earth objects (NEO) or lunar regolith. The refined material can be very valuable (there are high concentrations of rare and precious metals in NEO's), and then shipped back to earth more conventionally. Or used to construct in orbit.

    As we've witnessed, digging carbon from the earth (as crude oil and coal) and putting it into the atmosphere along with the heat energy from using it can have serious side-effects from injecting outside energy to a system in equilibrium.

    Power needs to go somewhere as some form of energy. It might do some work, but usually ends up mostly lost as heat. All lights, stoves, heaters, etc would essentially mean nearly all of the solar energy collected was as if the sun were simply shining brighter on the earth. Imagine if they were researching how to make more sunlight hit the planet just to harness it with solar cells -- this is almost exactly the same thing.

    Space energy is energy being brought into the system that wouldn't have normally entered. I don't see this as a viable form of energy. It will potentially lower greenhouse gasses, but will still screw up the ecosystem.

    No one makes us give away billions upon billions of dollars a year. NO ONE.

    The average American voter, when asked, guesses that about 15% of our budget goes to non-military foreign aid, and thinks it should be closer to 5%. In reality, it's 0.01% percent. Just, y'know, to put things in perspective.

    "However, NEVER forget that we also do some amazing things. We help literally millions of people a day soley because we WANT to."

    Yes. The US has historically done and presently does great and positive things for the rest of the world. That's what is so disappointing about the choices made in the last few years.

    It's nice to think that the US would help because it "wants to", out of its generosity, but the reality is that much of the food supplied to the rest of the world is dumped there to keep prices up domestically and to justify massive farm subsidies. It feeds the poor, but dumping that much food at low prices can undercut a country's attempts to build agriculture and an export trade in food (subsidies depress global prices, though many other countries are just as bad), and that can keep people poor. Anyway, to change this the US agricultural business and government policy would have to change drastically. They currently *need* to send grain and other foods elsewhere. So, is this generosity or merely necessity?

    It would also be quite difficult for the US to survive without energy and mineral resources drawn from the rest of the world, especially oil, what with >50% of oil imported. Historically, the US had a strong isolationist attitude, but that's long over, because the US simply could not survive for 6 months without the rest of the world's resources. At least, not with its current industrial structure. It's obvious that many military and economic choices have been made not out of some enlightened vision of helping the rest of the world, but primarily out of economic self-interest to keep the oil or (insert commodity here) flowing.

    A fairly clear example is Iraq. It's hard to explain the choice to go in there as anything other than getting access to oil. Iraq has about 25% of the known conventional oil reserves, second only to Saudi Arabia. All the original reasons for going in there have evaporated (and they were flimsy beforehand). WMDs? Ha. And everybody now knows the only terrorists in Iraq are the ones that moved in or people who decided to change professions AFTER Saddam was gone. Afganistan made sense at the initiation of the "war on terror", but it's only major resource is opium. It was an expensive operation on solid and globally-supported principles, but taking over that country doesn't pay the bills or feed the resource demands like taking over a country like Iraq. It's obvious the "war on terror" was an excuse in Iraq, and it was hoped it would be easy (decapitation strike indeed!). But if Iraq didn't have oil or threaten other country's oil, I doubt the US would care much.

    Yes, the US has and continues to do great and positive things, but you are fooling yourself if you think it is mainly out of generosity or even democratic principles. If it was, then the US would not have such a long and colorful history of propping up dictators and monarchs (e.g., in Pakistan, Saudi Arabia, Iraq, Chile, etc.). It has shown that it is quite willing to make shady deals with countries that just happen to have major natural resources needing development. And, look, here's a number of US-headquartered multinational corporations only too willing to lend a generous, helping hand!

    I'm sorry to be skeptical. I have great respect for the United States and its principles. Unfortunately I don't see much correlation between where and how the "help" is distributed in the rest of the world and those principles.

    The one exception is indeed during natural disasters, where the US has a good and fairly consistent record of offering and effecting aid regardless of who needs it. For that, the generosity of the US is immense and truly genuine. Thanks. The rest of the "help" you can keep. Unfortunately, I doubt the US could survive for long if it did what you suggest.

    The Earth has a radius of ~6,400km. The energy from the sun at the top of the atmosphere is about 1.3 Kw/m^2. Thats ~1.7x10^17 Watts. Its about the same as a 40 Megaton of TNT every second of every day. The amount of energy we use, either from space or from oil or from anywhere is a drop in the bucket and will be for a long time.

    The idea of blocking the sun to maintain the status quo on a climatic system we really don't understand yet, is stupid.

Living on Earth may be expensive, but it includes an annual free trip around the Sun.

Working...
