Leave it to Hong Kong

Remember my brilliant idea a few posts back?

Well, turns out it’s not such a crazy idea after all. Or a new one.

Converting elbow grease into electricity has a long, odd history. The first telephones, in the 1800s, had hand cranks that generated an electrical signal to alert the operator when one wanted to make a call. Hand-crank flashlights have long been available. So have hand-crank portable radios.

And apparently it’s not very efficient.

If all the exercise machines were in use 10 hours a day for a year, the gym could generate roughly $183 worth of electricity. At that rate, it would take about 82 years to pay off [a] $15,000 investment.

But I say, if we’re doing it anyway, we might as well use what we can, right? Who’s with me?
