Now that is cool. Perhaps we could task the maker community here in RI to get a LED based system up and running that’s powered by bike generators. I’ve got 100 each of red, green and yellow LED’s, and I think it’s still $1.95 per 100 on MPJA.COM
Then all we need is generators and the 12VDC motors on treadmills make great generators. Or we could wind our own.
