Compressed air is an energy storage medium, NOT a fuel. This bike runs on coal, natural gas, and nuclear fission, because those things are required to make the electricity that drives the compressor.

Just like electric cars, except a different energy storage medium.

The electricity is being produced anyway, in my part of the country mostly by hydro power. May as well use it. At least these wouldn’t be driving all over spewing fumes and noise like the two-stroke motors they usually run.

It’s a poor storage medium. It heats up as it gets compressed into the tank and must be removed. That heat gets wasted. It’s a significant amount of energy.

Maybe they could couple a compressor to the yuppies elliptical exercise equipment and it becomes a do-it-yourself project

I love making the comment to electric car owners: “Nice coal burner!”

The Fiskar people weren’t amused.

Exactly.

Liquid, chemical energy storage is still unbeaten for efficiency.

It’s worse than just an energy storage medium; it’s a very bad one.

When one strings together all the losses from fuel source (coal, gas, hydro, whatever), through the power plant, transition lines, compressor, heat losses from the compressed air cooling, and finally utilization, you are looking at an overall efficiency of about 10% or less.

It’s a rather incontinent fact every single one of these compressed air clean vehicle scam artist like to glaze over.
