New fuel discovered that reversibly stores solar energy

“Since the 1970s, chemists have worked on storing solar energy in molecules that change state in response to light. These photoactive molecules could be the ideal solar fuel, as the right material should be transportable, affordable, and rechargeable. Unfortunately, scientists haven’t had much success. One of the best examples in recent years, tetracarbonly-diruthenium fulvalene, requires the use of ruthenium, which is rare and expensive. Furthermore, the ruthenium compound has a volumetric energy density (watt-hours per liter) that is several times smaller than that of a standard lithium-ion battery.” via Read More → "New fuel discovered that reversibly stores solar energy"

Burt Rutan has designed a flying car unlike any other: it’s a hybrid

“The gasoline-electric twin-pod vehicle has a range of 760 miles in the air and 820 miles on the ground, and it works a bit like a Chevrolet Volt. Electric motors provide propulsion, while two gasoline engines drive generators that keep the juice flowing.

Design No. 367 — the craft is named in accordance with the simple numbering system long used by Rutan — was unveiled during the weekend after making its first short hop in the air on March 30. It is the legendary aerospace designer’s final project at Scaled Composites, the company he founded in 1982.” via Read More → "Burt Rutan has designed a flying car unlike any other: it’s a hybrid"
