Transatomic is developing a new kind of molten-salt reactor designed to overcome the major barriers to nuclear power.
A proposed engine design approaches the efficiency of gas-electric hybrids, but could be far cheaper.
The technology could make it cheaper to use wind and solar power and to switch to natural gas from coal.
Crop yields are expected to decline due to climate change faster than scientists thought.
But is the company scaling up its technology too fast?
It will likely take a decade, but improvements to lithium-ion batteries could lead to much cheaper EVs.
It’s not enough to have compelling technology—small solar companies need a solid business model, rich partners, and manufacturing know-how.
Better Place got it wrong: First make a car that people want, then build infrastructure to let them drive it cross-country.
Solar manufacturers like Suntech are struggling. Hundreds need to die for the industry to recover.
Global warming changes precipitation patterns, making some areas drier, and some far wetter.
