Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles, heelies, or an office chair: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

Hydrogen is the future of nothing but energy scams.
It has the big advantage of easy long term energy storage. You can store power made by PV in summer and use it in winter.
The water is cheap but the hydrogen requires special pressurized containers which in turn makes it lose its advantage over normal batteries.
Yeah, it blew my mind that the Toyota Mirai's hydrogen tanks are pressurized to 10,000 psi. To store a decent amount of hydrogen you need compress it to crazy high pressure or cool it with liquid helium or some other exotic extreme cooling. The thing about hydrogen that always confused me is that hydrogen is very energy dense but it physically not very dense.
It's not really energy dense. It's the single lightest atom in the universe, meaning it stores the lowest amount of energy. But it's very reactive chemically.
