Pentagon Urges Space-Based Solar Power
eldavojohn writes "The Pentagon issued a report indicating that space-based solar power 'has the potential to help the United States stave off climate change and avoid future conflicts over oil by harnessing the Sun's power to provide an essentially inexhaustible supply of clean energy.' The report, from the Pentagon's National Security Space Office, calls for funding the development of space-based solar power culminating in 'a platform in geosynchronous orbit bigger than the international space station and capable of beaming 5-10 megawatts of power to a receiving station on the ground.' The Pentagon's interest in such an effort stems from the need to acquire energy on the battlefield, which today often comes at a painful premium."
Sooo..... would this mean that the Pentagon could *bogart* all of the power when needed, or reduce power generation at critical times? This is one of the principal complaints about the GPS system as currently structured. There is no doubt that the GPS system has revolutionized much of the developed world and I am not criticizing that. On the contrary, I am just pointing out a possible criticism. After all, if the Pentagon (US government) plays its cards right, this could be a way to ensure that Gap Nations can be provided power to help them integrate into the Economic Core. (brilliant background on theory of Gap Nations and Economic core here ).

That's an excellent point.

Worse yet is something that didn't make it past the editing in my submission of this summary. I read around and it seems like a lot of people think that this budget for such an expensive extensive project would almost certainly be cut from any other alternative energy sources.
In my opinion, our defense spending is already through the roof, this could be a political move to put something powerful in space and get the money from alternative energy spending (or at least under the guises of it). Maybe my tin foil hat is on too tight but a lot of news sources were saying that this could drain and/or draw attention away from other just as valid efforts at escaping the grip of fossil fuels.
Like everyone's been saying, our solution to these problems of dependence on the middle east & emissions is going to be a host of different solutions specific to different areas. I fear that the funding and attention will go into this and we'll have all our eggs in one basket

It takes the military to come up with a REALLY stupid idea. We can develop better solar cells, or improve battery technology, or maybe put up more wind energy farms, but why not put the solar cells in space and beam the power down in focused beams with some sort of Buck Rogers scheme that has never been developed or tested and would probably, if it could work at all and not just be a cover for spending for a space weapons platform, be much more vulnerable to attack by potential adversary countries with access to space, e.g. the Russians or the Chinese. God save us from these morons.
Yes, this initial version doesn't generate a lot of power, but if the military were to actually go through with this plan, it would absorb the initial R&D costs to take orbital solar platforms from scribbles on the back of a cocktail napkin to a real, working prototype. Once the process is proven, then it would be a much smaller economic risk for the private sector to transition the technology to the civilian sector and expand capacity. Very few entities in the United States, let alone the globe, have deep enough pockets to absorb the immense financial risk and ready access to the limited pools of specialized aerospace engineering talent required as the United States military. Personally, I would rather have the military spending money on technology that has civilian benefits instead of buying yet another set of nuclear weapons.
The military has a problem. They need a lot of power for computers, communications, all the conveniences of modern warfare. *But*, they often work far away from any established (or reliable) infrastructure.
Space-based power would be a tremendous gain. Setting up base in a remote corner of Iran to perform Intel? No problem. Spaceman Spiff justs adjusts the microwave transmitter from the orbital solar array, and you get instant power.
I haven't thought through all the implications, but I can see substantial military advantages in something like this.
Your tax dollars -> Pentagon -> (Boeing, Lockheed, General Dynamics) -> Budget over-runs, late or no deliveries, CEOs even richer than before -> Your tax dollars down the toilet.
Been there. Done that.
Right...
Which is why the government & banks pump 10-14% more money into the economy every year, causing the stock market and property markets to rise exponentially and thereby moving value away from those who only have cash in the bank and CPI limited salary rises to those who own assets and stocks.
Do you have any idea what you're talking about?

Hmm.. Just how long does it take to recover the cost of building a terrestrial power station? I seem to remember a $25Million dollar gas power plant built just out side my town. They generate about $8Million a year selling power, which they have to pay for gas, employees, and the construction costs.. Of course, we're ignoring the cost of about $3Billion for the western power grid that it hooks into...(since were not mentioning the cost of downlink equipment, seems fair to not include the cost of distribution)
What are we going to do tonight Brain?
Because the US doesn't already have the power for an airstrike anywhere on the Earth? I believe political, rather than technical reasons, keep the US from blowing up things normally. Missiles and long-range bombers generally can get to where they need to bomb relatively quickly.
And weapons. The energisation of space will be accompanied by the militarisation thereof. No question. If there is a critical asset in orbit, something that the USA can simply not afford to lose, it will be protected. Even if this space-based power isn't a feasible weapon in its own right (and I can't really see, from any descriptions I've read online, how it could be), it will be protected. And critical orbital assets will be protected from space. There's no other good way to do it.
This is one of the reasons the US military is interested in space-based power. One of the many, of course. Providing troops with power is a benefit. The militarisation of space, the extension into earth's orbit of US control, is a benefit. It's an exercise for the reader to decide which is a tangential benefit, and which is primary.
What is is all that is. Isn't that obvious?
This response makes the assumption that the United States gives a shit about international law.
They don't.
Look up anything about the international court for proof.

Around Passover time, you can find coca cola in the U.S. with real sugar instead of HFCS (high fructose corn syrup). You will still have to travel to certain major metro areas (i.e. the ones with lots of Jews.) Google for "passover coca cola" for more information.
And you realize that's a crock right? Lots of countries with public health care run balanced budgets (Canada, New Zealand, etc). It's not about borrowing, it's about priorities. If the US wasn't flushing money down the toilet in Iraq, you could fund public health care and have money left over for a decent education system without a running a deficit.

It is impossible to switch to Ethanol. The Ethanol industry's own data (each gallon of Ethanol produced yields an excess of 17,000 BTUs. 125,000 BTU/gal Gasoline / 17,000 BTU/gal excess = 7) shows that it takes SEVEN gallons of Ethanol to replace ONE gallon of Gasoline. The average yield of Corn is 135 Bu/acre and each Bushel of Corn yields 2.68 Gal of Ethanol. To replace Gasoline with Ethanol made from Corn grown in the US would require 44 Million MORE acres of agricultural land than the TOTAL acres of agricultural land available in the US.
Add to that the fact that it is limited to one crop per growing season, is a mono-culture highly susceptible to natural or artificial pathogens, drought, floods and hail and you have what is probably the least desirable energy source of all.
What is pushing the Ethanol industry? Corn ethanol subsidies totaled $7.0 billion in 2006 for 4.9 billion gallons of ethanol. That's $1.45 per gallon of ethanol (and $2.21 per gal of gas replaced). There are 17 NEW Ethanol plants being built in Nebraska because of those subsidies.
What makes the WHOLE THING A TOTAL DISASTER is that Ethanol is NOT the path or even a bridge to energy independence. It is merely a drain on the Federal treasury driven by greed and corruption.

You mean the large farming conglomerates are killing us. The small farmer is glad to take a subsidy to not plant anything and let the fields recover. Archer Daniels Midland wants money from products.
