My gym actually does that. The elliptical machines actually tell you how much power you're generating. Going at a moderate pace generates about 90 watts. That's enough to light up about 10 modern light bulbs.
You're going to be generating that energy while working out anyway and it has to go somewhere. I think the biggest benefit is being able to direct where that energy dissipates. You can either put those 90 watts into the air as heat through friction, or put it into electricity through some dynamo. The second choice will make it so the place doesn't heat up as quickly.
- usrusr 7y ago> My gym actually does that. Do they really tell you how much energy they are harvesting as electricity or do they just tell you how much energy they are dissipating as heat? Because it is very common for sports equipment to measure/estimate the power applied by the athlete, in watts, all without the slightest trace of harvesting implied.
- rypskar 7y agoThe bike trainer I have tells how many watts I produce and how much is sent back to the grid, the number isn't high so is more geek stats than anything else
