What are you saying? The Chicoms got us beat in the batteries. We win if batteries are good don’t we. Solar power to feed them is free.
I set out two 100W [”Nominal”] solar panels today to do my part to help save da Erf.
Moved them around ~3 times.
A Meter says +0.64 kWh over 12 hours. [It was partly cloudy much of the day.]
My marginal kWh rate is $0.07/kWh.
I’m saving pennies/day, assuming that my time is worthless.
My father (Physics Academic) was doing battery research from ~1960 to 1980.
At which point he abandoned it and moved on to physics of surfaces, catalysis, crystal growth etc.
His conclusion was batteries were too dangerous (metal fires) and there were no likely breakthroughs coming in the future (both correct)
batteries are not close to competitive to fossil fuels, and likely never will be.
For applications like surface vehicles (let alone aircraft) where weight matters, batteries are a bust.
