I don’t necessarily expect to run whole cities off these [wind & solar] technologies, but there’s no reason, if we can overcome the limitations that they can’t be an eventual part of how we generate our power.

I won't say never. But there is one thing that will keep your unlikely dream from happening.

Subsidies.

So long as a technology is subsidized, there is no incentive to improve upon it.

You and I agree here.

There is no way GE or anybody whould receive one dime of subsidy for anything they are developing that they expect to receive eventual profit from.
