Ventura SPARC MGS Kinectic-powered Watch |
The Ventura SPARC MGS looks nice and futuristic and it uses a micro-generator to power a digital display. Your wrist movements feed an accumulator that provides power to the high-performance microprocessor.
The company claims that throughout an average day the wearer’s movements will turn the oscillating mass about 4,000 times. Through a set of connecting gears, these rotations are used to repeatedly tension a spring. Every time the spring is fully tensioned, it releases that force to a built-in micro-generator which generates electricity for the watch. Pretty cool.










Our favorite batteries are back. We’ve missed them. What other batteries are powered by your pee? Only
A battery charger powered by a battery. You will be free and untethered, assuming you have some D-sized batteries to power it. Isn’t this like robbing Peter to pay Paul? Or robbing Duracell to charge Energizer. Something like that.
Typically a battery functions with lithium ions flowing between a negatively charged anode, usually graphite, and the positively charged cathode, usually cobalt oxide or lithium iron phosphate. But three years ago, an MIT team reported that it had engineered viruses that could build an anode by coating themselves with cobalt oxide and gold and self-assembling to form a nanowire. The “virus batteries” have the energy capacity and power performance similar to rechargeable batteries.
This is pretty awesome in a Macguyver sort of way. Using a motor, USB cable, two compact discs and a paper or plastic tube, Instructables user msolek creates a sweet little USB powered fan. This is a pretty simple project and the parts are all inexpensive, so don’t be afraid to make one yourself.
