She has developed a simple, cheap way of producing solar cells in a pizza oven that could eventually bring power and light to the 2 billion people in the world who lack electricity. […]

Ms Kuepper realised a new approach would be needed if affordable cells were to be made on site in poorer countries: “What started off as a brainstorming session has resulted in the iJET cell concept that uses low-cost and low-temperature processes, such as ink-jet printing and pizza ovens, to manufacture solar cells.”

While it could take five years to commercialise the patented technology, providing renewable energy to homes in some of the least developed countries would enable people to “read at night, keep informed about the world through radio and television and refrigerate life-saving vaccines”. And it would also help reduce greenhouse gas emissions.

In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.

Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today’s announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.

Requiring nothing but abundant, non-toxic natural materials, this discovery could unlock the most potent, carbon-free energy source of all: the sun. “This is the nirvana of what we’ve been talking about for years,” said MIT’s Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and senior author of a paper describing the work in the July 31 issue of Science. “Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon.”

CNN has a brief article on the possibility of beaming solar power to earth from space:

The satellites would electromagnetically beam gigawatts of solar energy back to ground-based receivers, where it would then be converted to electricity and transferred to power grids. And because in high Earth orbit, satellites are unaffected by the earth’s shadow virtually 365 days a year, the floating power plants could provide round-the-clock clean, renewable electricity. […]

American scientist Peter Glaser introduced the idea of space solar power in 1968.

NASA and the United States Department of Energy studied the concept throughout the 1970s, concluding that although the technology was feasible, the price of putting it all together and sending it to outer space was not.

“The estimated cost of all of the infrastructure to build them in space was about $1 trillion,” said John Mankins, a former NASA technologist and president of the Space Power Association. “It was an unimaginable amount of money.”

NASA revisited space solar power with a so-called “Fresh Look” study in the mid-90s but the research lost momentum when the space agency decided it did not want to further pursue the technology, Mankins told CNN. By around 2002 the project was indefinitely shelved — or so it seemed.

“The conditions are ripe for something to happen on space solar power,” said Charles Miller, a director of the Space Frontier Foundation, a group promoting public access to space. “The environment is perfect for a new start.”
