One of the problems with rechargeable
battery toothbrushes is that they don't last
very long before they need recharging.
The motion they use though does clean
your teeth better than using an ordinary
So, this idea uses a
hand exerciser (a sort of springy thing you
- stop laughing at the back there -
see link) to provide power, which is
converted into the fast rotary motion like
that used in rechargeable battery
How about this type of power source? Post it as a new idea... [phoenix, Oct 04 2004, last modified Oct 21 2004]
Not the same thing at all, although the patent is for sale. It does suggest a mechanism for your device, though. [DrCurry, Oct 04 2004, last modified Oct 21 2004]
||Ha. This is the kind of idea we should be promoting.
||Um. Are you overlooking the good, old fashioned, hand-powered toothbrush (used effectively), or just trying to be funny...?
||What's next, the hand-powered chainsaw?
||Just try to make that old fashioned hand-powered toothbrush do that rotary motion.
