I wish I got to do fun little projects like this at my job. Anyway, this proof of concept shows that hydrogen would be a great alternative to propane and natural gas for cooking. Hat tip to @hypx@mastodon.social.

Electric is far more efficient too, thus cheaper. Electricity you can transit over distance over wire and generate however you like. We've done it a long time, far and wide.

Turning electricity into hydrogen, distributing it, and then turning it back into electricity to move a vehicle, is so wasteful/expensive.

Just use a big battery.

For some applications like spacecraft where weight is critical, it does make sense to use hydrogen fuel cells as a battery. But usually it doesn't make sense.

Certainly not the way we lunch right now. The energy used, that focused, in that short a time, is insane.
