There's this little company you may have heard of called GE. Yeah, it's the one Edison started and I don't know where you come down in the whole Westinghouse/Edison fight but one of those guys screwed Tesla and one did not, so I am inclined to like Westinghouse more than Edison even though GE stock obviously did much better.Hey, I can stick with my principles and still make some money.But GE has earned my respect, not because of Jack Welch (though he earned my respect, mostly by making the stock a gold mine and despite being a part of that annoying Six Sigma crap that has been foisted off on MBAs since the 1990s) but because they made smart grids seem kind of cool.What are smart grids?
