Times Square ball drop to be powered by Citi Bike this New Year's Eve

" The stationary bike generator will be pedaled by party goers at Times Square. It can accommodate six riders, with expected to produce 75 watts per hour. The Times Square ball is lit up by 30,000 LEDs and weighs "

I've watched how feeble my attempts at lighting a 100w bulb were at a science Museum, long ago.

screams gimmick with a brand name of a battery company on it to me.

but the Models are cute.

I'm reminded of Edward G robinson , lighting the room with an exercise bike - generator,

in the film, 'Soylent Green'.

Gimmick

You can believe there's a powered system in place running all. Possibly the bikes will "contribute" but nobodies counting on that and the ball HAS to light up and drop.

A gimmick? Perhaps. Seems to me the purpose is for fun and to raise pedaling awareness. As an engineer, I'm making an educated guess that the system was designed to provide some excess power to that needed light the LED ball with moderate pedaling output from the expected pedalers. If designing it, I'd suggest including a battery of sufficient capacity in the system to light the ball for the duration, then store pedal power from revelers ahead of time as a backup or assistance for those pedaling during the actual descent.

The act of the ball dropping itself could be applied to power.

but of course the energy to crank it up there , negates any thing it recovers.

And if it jams, the ball won't drop, and we'll all be stuck in 2013...

.

The drop is an electric winched system on a computer control, designed, tested and rehearsed so that the ball hits a specific point in it's travel at a precise point in time. There is NO WAY they are relying on pedal power for this !.

As reported: "The energy generated from the bikes through Monday was being stored in large batteries, and then transferred to the grid to offset the power demands of the ball."
