Great idea, but it’s cheaper to just include one of those strips that can tell how much juice is left. If our gadgets also shrank, this would be great. No idea what they are made of or how long they would last.

Here come the flesh-eating machines. The EATR project has hit a new milestone in the development of the reconnaissance bot, successfully coupling a steam generator with a compact biomass furnace. This means that it is possible for an autonomous machine to forage for and refuel itself with biomatter, otherwise known as our corpses.

They call it fuel versatility, as gasoline, diesel, and solar power may also be used. But our guess is that flesh tastes much yummier to robots. So run until you fall, at which time an EATR bot will finish you off for lunch. Humans USED to be the top of the food chain…
