A new paper claims neurons exchange virus like particles to share information and that this mechanism is connected to memory formation. Could this be why we have to sleep? To replenish the materials/energy needed to build these structures?

We always see glowing robot eyes in fiction. Would a glowing optical sensor actually work? How?

It seems so dumb that we use extra energy to boil water etc. during summer or in hot places. Do we have heat pumps that would allow us to cook or boil water while simultaneously cooling some other place? Would it make sense to use them?

Could we create an underground bunker/bunker network that could sustain itself longterm? Let's say at least a hundred years?
