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 :)

That sounds interesting. How big will it be physically?

About 5-6 liters, should fit nicely on the rear rack.

That is very cool. What cells are you using?

Cheap LG LGABB41865. They are low discharge, but since I have 2kWh of capacity I'm not going to be going north of 1C so it is well within spec.

Indeed, this high Specific Energy (~2000 Wh/kg) would be enough to make electric airplanes feasible and economical.

Heck, even high-altitude supersonic electric "jets", because you don't need oxygen to run electric motors!
