I think your confused… I’m not talking fusion, I’m talking fission, technology that has existed and has been used for many many decades… arguably out of all the “green energy” technologies that exist today it is the most scalable, affordable, safest as far as deaths, injuries and illnesses (that includes aftermath of things like Chernobyl, Fukushima, and 3 mile island) … and over its life the only energy technology that is truly carbon neutral and with little improvement carbon negative.

I’m not knocking the tech and I know the math… and as far as where we are today in our energy needs it’s promising, in my opinion things like nuclear are still superior because of shear energy density. Thorium is 35 times more energy dense than Uranium. 1 Kg of Uranium has an energy density of 45,000 kWh, 1 Kg of oil 12 kWh and 1 Kg coal only having 8kWh.

Better materials are great and all… the main issue with solar is even if energy transfer was 100% efficient, there is a finite amount photons per square cm, so eventually it’s a surface area problem and never having enough of it.

I’m not saying it’s problematic… I’m just pointing out a simple function of the limits engineering… the biggest problem is electricity needs to be consumed the instant it’s produced and there just isn’t an energy storage technology available today that is efficient enough to make it viable.
