Lightning. It just goes about it's business—mocking us. We have always known there is potential there for an alternative energy source, but harnessing that power has proven difficult. However, an inventor names Steve LeRoy may be on the brink of changing all that with a device that generates lightning then harvests the resulting energy. The prototype can generate bolts 3-feet in length, but that is only enough electricity to illuminate a 60-watt light bulb for 20 minutes. However, LeRoy notes that a full-scale version has the potential to power 30,000 homes for a day with just one lightning bolt. Impressive. With that kind of juice you could easily get a Delorean traveling through time. [Buisnessweek via Sci Fi Tech]
