Benefits of commuting on electricity Though electric buses are not newhe first was introduced in Berlin in 1882lder models frequently required wires to hang over each bus route, marking bus paths through city streets.

Volvo claims its plug-in hybrid buses can operate on electricity alone more than two-thirds of the time,

Moreover, as Ie previously mentioned, driving on electricity is compared cheaper to driving on oil. The expected operating cost-per-mile of an electric bus in New york is $0. 20 to $0. 30 cents,

No wonder why companies like Volvo and BYD are beginning to take advantage of the many reasons why cities are shifting bus fleets to rely on electricity instead of diesel.

Theye developed a superthin device that can be attached to an organ to generate electricity from its movements.

The tiny device is already within the range of generating enough electricity to power a pacemaker on its own,

it generates electrical energy from the movement. Because organ movements occur as pulses, the team had to include energy storage in their creation

so that electricity could be delivered continually. They accomplished this by building in a tiny chip-scale

The team found through testing that their system could deliver 0. 2 microwatts per square centimeter of stable electricity over 20 million cycles.

Their system converts mechanical to electrical energy at about two percent efficiency, a number that Rogers says is need based on the not to interfere with the target organ natural operation.

Potassium and sodium contribute the ions that control electricity in the brain. Researchers added fundamental physics principles of conservation of energy charge

and mass to an older theory of this electricity. They kept track of the energy required to run a nerve cell and kept count of the ions passing into and out of the cells.

Geobacter removes any waste produced during glycerol fermentation to generate electricity. It is a win-win situation.

These fuel cells do not harvest electricity as an output. Rather, they use a small electrical input platform to generate hydrogen and increase the MEC efficiency even more.

and converts it into electricity. Vast amounts of excess heat are generated by industrial processes and by electric power plants.

Researchers have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devicesâ##solid-state materials that can produce electricity from a temperature gradientâ

##but the efficiency of such devices is limited by the availability of materials. Now researchers have found a new alternative for low-temperature waste-heat conversion into electricityâ##that is in cases where temperature differences are less than 100 degrees Celsius.

When the battery has cooled it actually delivers more electricity than was used to charge it. That extra energy doesn t appear from nowhere explains Cui.

The process resulted in an electricity-conversion efficiency of 5. 7 percent almost double the efficiency of conventional thermoelectric devices.

This possibility is one of the reasons for the current interest in building the capacity to store electrical energy directly into a wide range of products such as a laptop

or a home where the dry wall and siding store the electricity that runs the lights

and discharge significant amounts of electricity while they are subject to realistic static loads and dynamic forces such as vibrations or impactssays Cary Pint assistant professor of mechanical engineering at Vanderbilt University.

The new device that Pint and Westover have developed is a supercapacitor that stores electricity by assembling electrically charged ions on the surface of a porous material instead of storing it in chemical reactions the way batteries do.

One area where supercapacitors lag behind batteries is in electrical energy storage capability: Supercaps must be larger and heavier to store the same amount of energy as lithium-ion batteries.

ut we ve found an easy way to do it. nstead of storing energy in chemical reactions the way batteries do upercapsstore electricity by assembling ions on the surface of a porous material.

Supercapacitors still lag behind the electrical energy storage capability of lithium-ion batteries so they are too bulky to power most consumer devices.

The supercapacitors would store excess electricity that the cells generate at midday and release it when the demand peaks in the afternoon. ll the things that define us in a modern environment require electricitysays Pint. he more that we can integrate power storage into existing materials

which can be absorbed by solar cells to make electricity a technology known as thermophotovoltaics. Unlike earlier prototypes that fell apart before temperatures reached 2200 degrees Fahrenheit (1200 degrees Celsius) the new thermal emitter remains stable at temperatures as high as 2500 F

and converts it into electrical energy. But silicon semiconductors only respond to infrared light. Higher energy light waves including most of the visible light spectrum are wasted as heat

CNTS are long chains of carbon atoms that are extremely efficient at conducting and controlling electricity.

Depending on how the CNTS grow a fraction of these carbon nanotubes can end up behaving like metallic wires that always conduct electricity instead of acting like semiconductors that can be switched off.

Then they pumped the semiconductor circuit full of electricity. All of that electricity concentrated in the metallic nanotubes

which grew so hot that they burned up and literally vaporized into tiny puffs of carbon dioxide.

That is roughly the same efficiency at which the best commercially available solar cells convert sunlight into electricity.

because it could offset some of the electricity now used to treat wastewater. That use currently accounts for about 3 percent of the total electrical load in developed nations.

Most of this electricity goes toward pumping air into wastewater at conventional treatment plants where ordinary bacteria use oxygen in the course of digestion just like humans and other animals.
