It’s A Bird, It’s A Plane. No, It’s A Space Solar Power Plant.
Thursday, April 1st, 2010Japan is already in the planning stages of putting up a Space Solar Power System that it hopes to launch in 2030, ten years after a test system is put into stationary orbit. It announced the program in November of last year.
So? Well it turns out that the Obama administration is basically shutting down the space shuttle system by cancelling a $9.4 billion program called Constellation, which would have produced a new series of powerful rockets launched from a mobile tower that’s already built–at a cost of $500 million. Constellation was to be the successor to the shuttle program, eventually landing once again on the moon.
But what if rocket technology advancement could bring Space Solar Power closer to reality? Apparently Japan thinks it’s worth a good look. So do people at NASA and elsewhere.
And Space Solar Power may be worth the effort. A sizeable base electric plant, powered by gas, can produce as much as 20 megawatts of power. One SSP can produce up to 100 times that much.
The idea is deceptively simple. Put a huge solar panel array into space where the sun’s power isn’t diminished by the atmosphere, to say nothing of clouds and all the rest. Concentrate that power into a microwave or laser beam and then send it down to a receiving power center on earth. From there it goes into the transmission system.
The idea was first seriously considered in the 1970s after the OPEC embargo. But gas prices eventually dropped down, and because today’s technologies weren’t yet invented, the idea died.
Today, however, the new technologies make the idea of a SSP far from far fetched. It could be done. It would be a massive effort on the scale of the Apollo effort that did put a man on the moon with the old technologies, but it’s no longer unthinkable at all. One missing piece of the puzzle, however, is that rocket technology needs to produce cheaper rockets. Sending this system into space would take a fleet of powerful shuttle rockets.
But stopping Constellation is likely to bring the US industry of making such things to a full stop. Talent and manufacturing would be lost. Even gearing up for upgrading the existing shuttle rockets would take two years because contracts are finished and plants shuttered.
Writing in the New American, former NASA journalist and author Beverly Eakman responds to the Obama decision, in part, with the following:
“NASA’s research had already produced a whole wave of new technologies people hardly thought about — ball bearings for drill bits in dentists’ tools; wireless, hand-held calculators; remote sensing platforms for measuring pollutants and identifying mineral, water and geological fuel sources; air-bubble wrapping for shipping; instantaneous transmission of voice and picture; and much more, though the increasingly left-leaning news services rarely mentioned them back in January 1976, when my 200-page in-house document, “Space Program Benefits and Applications,” was published.
Moreover, to say that the “sky was the limit” was no mere, casual expression. To say that we owe marvels like cell phones (with all their various “aps”), high-definition televisions, laser-medical devices, nuclear medicine, nuclear power plants, and the Internet in large part to NASA-inspired efforts is an understatement.
Yet, unbelievably, we blew it!
Until now I have remained silent, except to a few movers and shakers in the NASA establishment (who basically agree with me, but say that politics has essentially trumped practicality), but a just-published piece in Sunday’s Washington Post, “NASA’s $9.4 billion mission to nowhere,” (NASA’s $9.4 billion mission to nowhere) was the last straw. Had we pursued what was already on the drawing board in 1978, we would be essentially finished today. The few items in popular use that might still require fossil fuels would not necessitate overseas imports for hundreds of years, and given the rate of technological advance, even those few would probably have yielded alternative methods by now.”
A couple things are certain. The global population continues to grow and the sources of energy continue to decline. Re-considering a fantastic solution to future energy needs that is well within the ability of current technologies might be worth keeping America’s rocket industry alive and well.
There’s a nice 19 minute video about the entire concept at the Future’s Channel.
And at the National Space Society there’s this:
“Advantages of Space Solar Power
-
Unlike oil, gas, ethanol, and coal plants, space solar power does not emit greenhouse gases.
-
Unlike coal and nuclear plants, space solar power does not compete for or depend upon increasingly scarce fresh water resources.
-
Unlike bio-ethanol or bio-diesel, space solar power does not compete for increasingly valuable farm land or depend on natural-gas-derived fertilizer. Food can continue to be a major export instead of a fuel provider.
-
Unlike nuclear power plants, space solar power will not produce hazardous waste, which needs to be stored and guarded for hundreds of years.
-
Unlike terrestrial solar and wind power plants, space solar power is available 24 hours a day, 7 days a week, in huge quantities. It works regardless of cloud cover, daylight, or wind speed.
-
Unlike nuclear power plants, space solar power does not provide easy targets for terrorists.
-
Unlike coal and nuclear fuels, space solar power does not require environmentally problematic mining operations.
-
Space solar power will provide true energy independence for the nations that develop it, eliminating a major source of national competition for limited Earth-based energy resources.
-
Space solar power will not require dependence on unstable or hostile foreign oil providers to meet energy needs, enabling us to expend resources in other ways.
-
Space solar power can be exported to virtually any place in the world, and its energy can be converted for local needs — such as manufacture of methanol for use in places like rural India where there are no electric power grids. Space solar power can also be used for desalination of sea water.
-
Space solar power can take advantage of our current and historic investment in aerospace expertise to expand employment opportunities in solving the difficult problems of energy security and climate change.
-
Space solar power can provide a market large enough to develop the low-cost space transportation system that is required for its deployment. This, in turn, will also bring the resources of the solar system within economic reach.
Disadvantages of Space Solar Power
-
High development cost. Yes, space solar power development costs will be very large, although much smaller than American military presence in the Persian Gulf or the costs of global warming, climate change, or carbon sequestration. The cost of space solar power development always needs to be compared to the cost of not developing space solar power.
Requirements for Space Solar Power
The technologies and infrastructure required to make space solar power feasible include:
-
Low-cost, environmentally-friendly launch vehicles. Current launch vehicles are too expensive, and at high launch rates may pose atmospheric pollution problems of their own. Cheaper, cleaner launch vehicles are needed.
-
Large scale in-orbit construction and operations. To gather massive quantities of energy, solar power satellites must be large, far larger than the International Space Station (ISS), the largest spacecraft built to date. Fortunately, solar power satellites will be simpler than the ISS as they will consist of many identical parts.
-
Power transmission. A relatively small effort is also necessary to assess how to best transmit power from satellites to the Earth’s surface with minimal environmental impact”
Beezer here. So if you’re tired of thinking about Industrial Ag, Tea Baggers, TBTF Wall Street banks, health care reform or Washington politics in general, here’s something different to ponder. Space based solar power.
