The beauty of an energy-free treadmill

I've been coveting the world's best manual treadmill, the EcoMill ($7,000). But until I have a spare seven grand, I have to run with conventional electric mills. Most use a lot of juice — between 800 and 1800 watts continuously — because they have ot lock down a consistent pace with a low-cost mechanism.

At a sleepy little gym and pool complex here in Vermont, on a conventional electric machine this week, the current was so high it overloaded a nearby stereo receiver playing upbeat pop music for a water aerobics class. All of a sudden, seven wet, angry seniors swarmed from the pool. Encircled by bright floaties, they demanded I quit running so the music would come back on. I tried to explain the concept of a blown fuse and how treadmills use high wattage because they can't rely on the friction like spin bikes and how the world really should invent a cheap electricity free mill. But at that only enraged them, and they gripped the handrails and rocked the machine side to side.

I really want my own EcoMill for the house. Or maybe a human-sized hamster wheel.
