Cordless Drill Hydro Generator

Posted: October 24, 2011 in Survival, Thoughts

Cordless drills can be used for many applications in a SHTF scenario, they are cheap and can be converted to charge batteries with a little ingenuity..

here are a few other idea’s from popular mechanics

Drill Driver
Geniuses: Sebastian Auray, Ruben Faber, Nils ferber, Ludolf von Oldershausen
Location: Hamburg, Germany

Moving at 20 mph doesn’t sound so harrowing—but if you’re driving the EX—a tricycle designed by an obsessive team of students at the University of Fine Arts of Hamburg, Germany—20 mph seems more than fast enough.

Perhaps that’s because the EX positions its driver so he’s sprawled out on his belly on top of the three-wheeled vehicle, with his face the first point of contact for any oncoming traffic. A specially designed, CNC-milled joint tilts the back wheel to let the rider lean into turns. Modified bicycle parts were used for most of the components—and the trike is powered by nothing but a pair of battery-operated Bosch drill drivers. The 18-volt power tools crank the chain ring in the same direction for maximum, if modest, power; to avoid one drill driver blocking the other, overrunning clutch gearwheels are used to transmit the torque. “The torque you get from a screwdriver is pretty small,” Nils Ferber says. “But we wanted the vehicle to look as aggressive and energetic as possible.”

The design team drew inspiration, he says, from the skeletal structure of a big cat ready to pounce, though he agrees that this is one skeleton perhaps best left in the closet—or at least the workshop. Fully charged drill drivers poop out after a few minutes, giving the rig a maximum range of about a mile and making it about the least practical electric vehicle ever. But for those few minutes? “It’s exciting and fun to drive,” Ferber says. “Being that close to the ground and lying on the vehicle headlong, I’m almost glad that I can’t go faster than 20 mph.”
