LOW ROLLING RESISTANCE TIRES

Only about 12 to 20 percent of the energy produced by the engine actually turns the wheels, and about one-third of that is consumed by rolling resistance. As you drive down the road, your tires squirm and deform every time you go around a corner, accelerate, or apply the brakes. The repeated tire deformation between the tire and the road, within the tire and between the tire and the rim, causes mechanical energy to be converted to heat; hence additional mechanical energy must be supplied to drive the axle.

NO MORE BATTERIES

How ultra low power wireless networks and energy harvesting are going to make our planet a better place to live.

NREL REPORT - CONSUMERS AND GREEN POWER

The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) today released its annual assessment of leading utility green power programs. Under these voluntary programs, consumers can choose to help support additional electricity production from renewable resources such as wind and solar.

SEMANTIC SEARCH REIGNITES HYDROGEN FUEL RESEARCH

The Obama administration has made alternative fuel research a key objective for the country. Researchers in the area of hydrogen fuel cell research therefore are faced with a plethora of peer reviewed publications that they must read to stay abreast of not only the latest publications but also historical publications that may be relevant to a current discovery.

THE ROAD TO ENERGY SELF SUFFICIENCY

Have you ever bought a lottery ticket? Everybody loves a good contest. Let's have a national contest to devise a solution for our energy problem. If this plan is launched there will be innumerable business plans being word processed before the next dawn. Can you imagine having the patent on the replacement for oil? How valuable would that be, tax free? As a spin off value of this contest, can you imagine having the patent to create a new source of water, and be able to sell it to the drought stricken Mid East and Africa, and have the profits being tax free for ten years? How valuable would that be? How many people / companies would be lining up to participate?

TIDAL WAVE INDUSTRY ANALYSIS

While the wave energy industry is still in its infancy phase of development, America and the rest of the world are realizing the catastrophic effects of the oil industry's grip upon the global economy. We look at hydrogen and solar energy as viable alternatives to oil. In addition, tidal wave energy is a phenomenon that should be seriously considered as a viable form of energy for people to power their homes, cars, and boats.

COMMERCIAL HOT WATER SYSTEMS

The high cost of heating water in hotels, restaurants, health care facilities and other big users may now be cut drastically with a geothermal heat pump.

SUSTAINABLE BUILDINGS FOR SUSTAINABLE FUTURE

The Institute of Rural Research and Development (IRRAD) is an initiative of S.M. Sehgal Foundation working on poverty reduction in rural villages in the State of Haryana, India. IRRAD's campus, which resides among some of the ultra-modern high rises of Gurgaon, meets the standards of the Leadership in Energy and Environmental Design (LEED) Green Building Rating System'. It generates 35Kw of solar energy on-site, enough for all the electricity requirements of the building except air-conditioning.

ALTERNATIVE ENERGY STORAGE

America's electric power grid is subject to immense inefficiencies that arise from the interplay between centralized power generation, local power consumption and on demand utility service.

COGENERATION FACILITY AT 102% EFFICIENCY

Remember the First law of thermodynamics? Energy can neither be created nor destroyed. It can only change forms. Or, if translated into an idiot-proof rule of thumb: you can't go above 100%. Remember this? Now forget it; this law has got a loophole.

DISTRIBUTED GENERATION - MICRO GRIDS

The term micro grid is mentioned more and more in publications on distributed generation. It generally means a collection of consumers, generators and potential energy storage entities connected together and operated as a small grid which is connected to the main grid, but capable of operating a self-sufficient island. The micro grid is typically linked to the grid with the help of a switch, which allows it to work both in grid-connected as well as island mode. However, island operation is not currently permitted in the majority of countries.

DRIVING THE HONDA CIVIC HYBRID

The electric motor gave the car a very smooth acceleration, with gear changes needed less often than I'm used to, and a very smooth delivery of power. The electric motor also seemed to smooth the gear changes so rather than the jerky transition you can get when accelerating and changing gear, it was altogether a more refined experience.

ECOFA - BIOFUEL MADE WITH GARBAGE

A group of Spanish developers working under the company name Ecofasa, headed by chief executive officer and inventor Francisco Angulo, has developed a biochemical process to turn urban solid waste into a fatty acid biodiesel feedstock.

HYDROGEN - BECAUSE WE NEED IT!

What follows is not meant to bash EVs, plug-ins or biofuels. And yes, hydrogen faces substantial challenges, chief among them vehicle cost and fueling infrastructure. But we need to be honest about all the options, or risk falling down the rabbit hole with Alice.
