A Challenge: DIY gravity lamp
I have some ideas about how to make it possible using some existing instructables and I though I would share this to get people thinking about new ways to use gravity as a power source. Think about it, gravity is clean, constant, eternal and EVERYWHERE.
I think that this instructable has some of the essential components: Cordless Drill Crank Charge Batteries
It gives a basic example of kinetic energy being converted into electricity, but for this application
the kinetic energy will be supplied by gravity instead of the hand crank.
The real fun with this project, I think, is the different ways that the kinetic energy of the weight can be harnessed. The screw used by the Gravity Lamp is just one method. A weight on a rope that is wrapped around a spool or crank is another option or even something based on the mechanism of a grandfather clock. One could even imagine a single massive weight that the whole family would hoist, with the help of pulleys, every evening to power their home lighting. Who knows.....
It's time to start a gravity revolution.
