this is a great concept...
exercise bicycles in McDonald's restaurants for customers who want to charge their Smart Phones
years ago I joke that people in the workplace should have this sort of device for powering their computers
but this is even better
EVERY SUBWAY STATION
and then also
heavily trafficed bus stops could do well to have these
then go ahead an place something like this in public parks
maybe parks that are popular spots for homeless and the less fortunate could have these sorts of devices
would be a great concept
someone make this happen
