Caps suck for storage. Unless you could change the capacitance, your voltage has to increase parabolically to store more charge, but at the same time the impedance increases with charge in the capacitor.
Chemical storage is mostly linear for most of the charging time.

hmm, they exist but they are tiny, a 1F super varactor would be more like it

> time for some math
inp: 5V 1Amp sec (5 watsec)
buck/ lossless: 1V 5Amp sec (5 watsec)

varactor in high capacity mode : 1milliFarad @ 1V (1 mA/sec @ 0.5v average -> 0.5 mwatsec)

varactor in low capacity mode : 0.2milliFarad @ 5V (0.2 mA/sec @ 2.5v average -> 0.5 mwatsec) * five seconds?

Integral fast reactors used as a combined heat and power system for cities may be a massive boon for said cities for power and heat supplier. Using fuel waste and breeding it without being research intensive like MSRs and more efficient than LWR or PWRs. Combining it with supercritical CO2 turbines may be a winning combo for mass grid power.
Building microgrids would be a great leap in building energy efficiency as well

it's mostly glas and an aluminium frame so the carbon footprint is about the same as for a window
> Will it produce enough energy in its lifetime to make up for it and more?
It will,surprisingly fast. In a sunny place like California it will take a few months. But more important it's the only power plant you can put on your roof. You can become indendend and even make money.

Maybe up to 5% if you count for a/c and heating.
