Shouldn’t you be able to drastically conserve power while also having a lot less headach by just driving or walking ar night?
Let’s say you’re driving with a bike, several liters of water and a tent.
You stay in the tent at day, always being in the shadows. (Putting up covers and “sunshields”. You’re drinking as normal and when the sun goes down, you start driving until it rises again, the cycle repeats.
Wouldn’t that be the most relaxed way through the desert possible
