In the 60's big oil promoted solar and wind because it knew we didn't have the tech to make it work so it was a strawman compared to the reliability of oil.

I think this is close to the same thing. We don't hear about it because it works, and would disrupt the system, and before long, people are shooting nails out of electro rail guns because power is cheaper than bullets. Or that's what the big guys use as reasoning to prevent cheaply available power.
