Save Energy with the SpinX Clothes Drying Centrifuge

Two minutes in the spindryer will save you thirty minutes in the clothes dryer!

So says the website of Spin-X, the clothes drying centrifuge. You may have seen similar devices at your local public swimming pool, allowing swimmers to quickly dry their swim suits before placing them in their gym bags. The Spin-X attempts to bring that same centrifugal power into the home. The site has a list of reasons to use the Spin-X, including this one addressing the important energy usage question:

[The device] Will remove one quart of water from clothing using only 15 seconds worth of clothes dryer electricity.

At $450, the device would take a while to pay for itself, but the energy (and therefore cost) savings combined with quicker dry times and environmental benefits would appeal to many. Could this device not, theoretically, be constructed to harness human foot power instead of electricity, or perhaps a version that would allow you to use electricity or muscle power, at one's discretion?
