The CEO of IBM in 1952 said there would never be a market for more than five computers... Right now is 1952 for solar. Those who recognize that fact will be tomorrow's Bill Gates. The industry is still maturing, reducing costs, increasing efficiencies, and reaching economies of scale. To dismiss the long-term profit potential is like saying you wouldn't invest in Apple (NASDAQ: AAPLE) in 1985 when it was $1.84. You'd have been an idiot who missed out on 19,500% gains. It'd be like saying personal music players would never catch on when they still looked like this in 1975: One of my favorite charts showing the forecast growth of solar for the next decade: Just keep that in mind when pondering the future of energy. The "here and now" perspective isn't always the correct angle to view the situation. Advances are being made every day. And it won't be long before solar goes the way of the iPod... Everyone will have one. The key is...

As the turbines spin, clean renewable energy will flow into the power grid. In short, it's an interesting mix of the best of both solar and wind power; but unlike solar and wind, the mechanical energy created by Davey’s machine allows the unit to operate 24/7. As for cost, the project has a $750 million price tag. According to a 2005 industry report, this would imply about 10 cents per kilowatt-hour, which is roughly one-third the cost of electricity from current solar cells and almost half of the cost from nuclear power. Financial models suggest the tower will pay for itself in 11 years; engineers believe the tower will have a life span of 80 years. Once it’s built, Davey’s tower can be expected to produce power with virtually no maintenance. Better yet, it requires no "feed stock" — nothing but air and sunlight spin the turbines...Instead, hot air rushes out of the huge, towering mouth of Davey's creation — enough hot air, in fact, to turn a massive turbin...
