‘Solar’ jet fuel made out of thin air
The dream of producing hydrocarbon fuels from carbon dioxide and sunlight is one step closer thanks to chemists in Europe who have made jet fuel from scratch in a solar reactor for the first time. Although the chemists only produced enough kerosene to fill a glass jar, they believe a full-scale solar concentrator could produce 20,000 litres of jet fuel a day.

Germany Sets New Record, Generating 74 Percent Of Power Needs From Renewable Energy
On Sunday, Germany’s impressive streak of renewable energy milestones continued, with renewable energy generation surging to a record portion — nearly 75 percent — of the country’s overall electricity demand by midday. With wind and solar in particular filling such a huge portion of the country’s power demand, electricity prices actually dipped into the negative for much of the afternoon, according to Renewables International.

Who leads the world in small-scale solar power? Try Bangladesh
Sometimes being behind is a plus. With an unreliable electric grid, many in Bangladesh have gone solar, making the country a worldwide leader. Meanwhile, in Tunisia, doctors are offering to help women become "virgins" again, and Colorado grapples with just how public its newly-legal marijuana should be. That and more in today's Global Scan.

Can crowdfunding give us safe fusion power by 2020?
A group of researchers at New Jersey-based LPP Fusion is turning to crowdfunding to demonstrate net power gain from a nuclear fusion reactor. The scientists plan to do this using a technique which is relatively little-known, but which they claim is scientifically sound and only relies on well-established science. Given enough funding, the researchers say they could design a US$500,000, 5 MW reactor that would produce energy for as little as 0.06 cents per kWh, all by the end of the decade.

This Giant Tower In The Desert Could Generate As Much Power As The Hoover Dam
If the Solar Wind Downdraft Tower is ever built in the Arizona desert, it truly will be a wonder of the modern world. At 2,250 feet, it would be taller than the new Freedom Tower in New York, and higher than the Empire State Building. It would have 120 huge turbines at its base, and enough pumping capacity to keep more than 2.5 billion gallons of water circulating. And it would have colossal power output: the equivalent of wind turbines spread over 100,000 acres, or as big as the Hoover Dam.
