The sugars in a cockroach’s belly have been harnessed by a fuel cell and converted into electricity, a big step toward turning insects into cyborgs, scientists are reporting.
Once miniaturized to the point that the fuel cells are non-invasive to the cockroaches, they can be implanted to power sensors or recording devices, for example.

A new generation of workout machines that generate electricity as you work up a sweat are poised to invade fitness centers and help you keep your New Year’s resolution to trim down your waistline.
The electricity generated by the machines is fed back into the grid, helping the gym save on its utility bills.

Bikes with an electric-motor assist are beginning to change the way people get around town, according to experts who declare the age of the e-bike is upon us.
E-bikes look and operate similar to their traditional pedal-powered equivalents, but contain a battery-powered motor that kicks on when, for example, pedaling up a menacing hill.

Your credit card bill tells you how much you spent on gas last Tuesday, groceries on Wednesday, and football tickets on Friday night. Wouldn’t it be helpful if your electric bill did something similar?
This isn’t pie in the sky for Shwetak Patel, a 29-year-old technologist who received a $500,000 “genius” grant Tuesday for his work on inexpensive and easy-to-deploy sensors that can make our lives more efficient and enjoyable.

Electric vehicles outfitted with a $10 computer chip can help streamline the addition of wind power to the electric grid, according to a study that shows how the two types of technology could piece together the puzzle of our green energy future.
One of the biggest hurdles utilities face with the addition of wind power and other renewable sources of energy to the grid is where and how to store excess generation for use when people actually need it. Until that happens, if the wind blows when nobody needs electricity, for example, the energy is wasted.

The high-tech magnets in modern MRI systems encountered at the doctor’s office may soon generate electricity from the wind, according to researchers at the General Electric Company.
MRI systems are the tube-like contraptions that make images of damaged hearts, torn ligaments, brains, and other body tissues. Instead of X-rays, the images are made with superconducting magnets, which are electromagnets made from coils of superconducting wire.

Scientists have downsized the electric motor to the molecular level. That is, they’ve created an electrical motor that’s the size of a nanometer. About 60,000 of them equal the width of a human hair.
The molecular motor is a breakthrough that could lead to new types of electrical circuitry, according to Charles Sykes, an associate professor of chemistry at Tufts University in Massachusetts.
