I keep seeing "sure, maybe solar works, but what about all the materials you need for the batteries?"
A battery that can store 100% of the daily production of a solar panel - *weighs less than the solar panel.*
Batteries are the most mass efficient way to provide peak power.
Jesse Peltan@JessePeltan· 3 mai 2025At ~150 Wh/kg, a 23kg LFP battery pack could store the full daily production of a 38 kg 720 W solar panel.
Solar + batteries provides orders of magnitude more energy per unit mass compared to any chemical fuel.
A battery has a much lower specific energy density than diesel, but
