I wonder how efficient it is. Let’s say the bike is 90% efficient, the pump is 70% efficient and the pneumatic power tools are 70% efficient, so you get 44.1% efficiency.
If you give or take 10% from/to each of those, you can get as low as 28.8% efficient or as high as 64% efficient.
If you build the electic equivalent (generator, battery and electric powertools) it is probably twice as efficient or more. Pedal for only a half to a third as long.
Yeah it is pretty cool in that regard. I was just wondering how it compares and thought it might be interesting for others.
I would be cool to optionally hook up wind power up to it too. You can easily DIY one with more than 1000 kW peak power, which is athlete levels of output for a human.
Depending on your useage and size of tank, intermittency shouldn’t be a problem, but if it is, you can always slap on the bike again.
You loose around 30% of energy from the sun through the atmosphere, plants are about 3% efficient at turning light into sugar, humans are about 25% efficient at turning food into mechanical energy, so you are only about 0.525% efficient at turning energy from the sun into human power on earth.
So you this device is only about 0.231525% efficient at turning solar power into usable work.
Assuming 80% efficiency for the electric variant, 20% efficiency for solar panels, 90% efficiency for robots to turn electricity into mechanical work, that’s 14.4% efficient. Then it’s like 62.196307 times more efficient to become a solar electric android and pedal on it in space.

Using belts instead of chains would also make sourcing all the parts much easier, like in ye olde steam powered workshops.
Efficiency isn’t that big a deal anyway when you use abundant power like water or wind.

While this is true, I would also consider the stability of the system, the ease of repairing it, and the availability of components if necessary.

Adding to this: This is basically turning solar energy in stored energy. Solar power-> growing Plants-> Man eats Plants-> kinetic energy-> storage
Simply take a solar panel and a battery.
