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.

At ~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
