Let's make the assumption that this can work in the real world for a moment -- big if ...

If the US Government funded this at a critical mass level, say $3 Trillion Dollars over 10 years -- would the ROI from the replacement of fossil fuels with solar be in the black? And then how many years to recapture the investment?

If a project like this could be a net gain in 20 years by all means do it.

More than likely it will take 10 or 20 years to sort out the details. Fuck the fossil fuel producers and the current energy suppliers -- adapt or die! We need to get back control of our energy costs for prosperity to return.
