They are, however, more versatile: A 20-story building has about 10 times more space for PowerGlass than it does for roof panels.
Yeah, I'd say that rocks.
Imagine a A/C compressor in your auto not belt driven, but electrical. Hey, when it is usually hot, it usually sunny, no? There are companies that are building more efficient A/C compressors (Unfortunately car companies like to do like the U.S. govt., build cheap, sell high) and we could very well see a 10% gain or more in, coughs, fuel combustion engines. For the hybrids? The sky is the limit.
