Surely once energy is practically free due to harnessing solar, wind and ocean energy it’ll be cheaper to create hydrogen. Surely military vehicles can be transformed to run on hydrogen.

- Valgrim 4y agoAny liquid fuel is cursed by the tyranny of the wagon equation (see https://news.ycombinator.com/item?id=32735688 https://news.ycombinator.com/item?id=32735688 ). At the price a liter of any fuel gets at the end of the supply chain, a lot of things become economically viable: beamed energy from space, for instance. One advantage of this is that, contrary to liquid fuel or solar panels or even portable nuclear reactors, the enemy cannot capture your source of power (unless the war reaces space, of course) Edit: found a source https://afresearchlab.com/technology/space-power-beaming/ https://afresearchlab.com/technology/space-power-beaming/
