Since the 1950s, the brain of any electronic device has been a printed circuit board (PCB), a piece of substrate that contains all—or most—of a device's electrical components, including wires, switches, and processors. Rather than using PCBs simply as a control center, engineers at Montana-based CORE Outdoor Power are using them as a power source. They've developed a PCB-based rotary motor that's as strong as a gas-powered one, but without the emissions and noise.
The CORE motor consists of a circular multilayer PCB sandwiched between two ring-shaped magnets. Electricity from a lithium polymer battery passes through 10 layers of copper
conductors in the PCB. The current causes the magnets to spin, which then turns the motor.
CORE's motor is built into the Power Lok yard-tool system. A battery-equipped base unit transfers power to swappable hedge-trimmer, string-trimmer, and blower heads, each with its own 0.5--–1.5hp motor. The company says the technology is scalable; it's already created motors that produce up to 4,000 hp—enough to run wind turbines, ventilation systems, and even oil pumps.

"...it’s already created motors that produce up to 4,000 hp—enough to run wind turbines...."
..not going to need those damn windmill bird chopping blades anymore, just run it with one of these Unicorn motors...
i'd like more details about the motor, what exactly makes it different then the fact that they just used PCB as the rotor?
to mars or bust!
I just agree..Start working at home with Google! It's by-far the best job Ive had. Last Monday I got a new Alfa Romeo from bringing in $7778. I started this 9 months ago and practically straight away started making more than $83 per hour. I work through this link, Bling6.com
just before I checked out the bill of exchange of $5122, I did not believe that...my... brothers friend was actualey receiving cash part-time from there new portable computer.. there dads pal has been doing this for beneath fifteen months and recently cleard the morgage on their appartment and bourt a brand new Ford Focus. we have a tendency to looked here...... www.bay95.com
