I was wondering what everyone thought about this? With the renewable energy advancements in solar, wind and the latest in battery and capacitors (super capacitors) technology and the energy crunch, global warming, and oil prices. And the fact that the only reason that we began using Alternating Current to began with was for the distribution of electricity accross the US. Thomas Edison ran electricity to the first city using Direct Current, because that was all he new, and that was where he was passed up in technology by Tesla and alternating current. Most of our small electronic devices are DC, all are cars use DC, cordless drills, saws, cell phones and as far as lighting, LED is efficient and the lamps last for decades, they also can use battery's as backup. There are already alot of advantages to using DC. Soon we will all have our own renewable power plants on our roofs of our buildings and houses that produce DC and we will be driving electric cars that are DC, so why would we ever convert DC it into AC at all?
