Personal fans that run all day. Tiles that keep working for decades. Traffic lights that can be deployed by police wherever they're needed. E-Bicycles that can outrun and out-range most bus routes. Electric airplanes make air travel significantly quieter and much cheaper. Internal combustion engines made obsolete and reduced to a historical curiosity. Electric scooters dominate worldwide as honda cubs become too expensive to fuel. I want it all.
Ebikes can already outrange most bus routes. I'm building a battery pack right now that should give a range of 150-180kms realistically, for about 300$CAD. That said, it's going to be pretty heavy at 10kg, but that's less than the amount of textbooks I was carrying just a few years ago :)
