Honda "smart home" showcases off-the-grid energy solutions

By - April 29, 2012 25 Pictures
Honda has unveiled a demonstration house in Saitama, Japan, to showcase and test its new Honda Smart Home System (HSHS). Featuring a line-up of innovative energy production, management and conservation solutions, the company hopes HSHS will free homeowners from the constraints of on-grid living somewhat, give them a leg up on self-sufficiency when disaster strikes and help reduce carbon dioxide emissions both at home and on the road by networking electric vehicles into the mix.

Nanocrystal-coated fibers show promise for harvesting waste heat

By - April 25, 2012 2 Pictures
Researchers at Purdue University in the U.S. have developed a new method of harvesting vast amounts of energy from waste heat. Using glass fibers dipped in a solution containing nanocrystals of lead telluride, the team led by Dr. Yue Wu is engineering a highly flexible thermoelectric system that generates electricity by gathering heat from water pipes and engine components.

Less power to cell phones, more power to the people

Smart phones are techno wonders, and they are also energy guzzlers, which is not a problem for people living in the developed world. However, their high energy requirements has stymied the adoption of mobile internet services in developing countries where mobile internet can be a real lifeline. In Africa, for example, few people can access the internet from a wired connection but 90 percent of the population lives in areas with mobile phone network coverage. There’s one problem though. Access to the power grid in Africa is limited. Read More

Versatile Wind Harvester breaks from traditional turbine design

By - February 22, 2012 4 Pictures
From huge kites to sea-bound flywheels and roof-top installations to tree-like art creations, we've seen many different approaches to capturing energy from the wind. One design, though, reigns supreme - the tri-blade turbine tower. It's not exactly a trouble-free life at the top and there are those who do not look upon these monsters favorably, most often complaining about the noise and the not so picturesque view. With support from Nottingham Trent University's Future Factory project, Heath Evdemon is currently building a new type of wind turbine called the Wind Harvester that's claimed to be virtually silent, doesn't need to loom high over the landscape and can operate in a variety of wind conditions.

NASA launches search for greener propellant

By - February 9, 2012 1 Picture
NASA has put out the call for greener propellant fuel for use on the spacecraft of the future. Though it does not appear that NASA has stipulated that alternative propellants must match the performance of current mainstay hydrazine, it's clear that only high-performance substances need apply. Environmental credentials are where the new fuel must demonstrate an edge over hydrazine, which is a corrosive, toxic pollutant. As well as the environmental benefits, use of greener propellants should prove more economical, reducing the need for involved safety procedures that can lengthen launch times. Read More

Eco Wave Power developing two new wave-power devices

By - January 8, 2012 9 Pictures
Israel's Eco Wave Power is just entering the second phase of proving its new wave energy harvest and conversion system that's claimed to produce cheaper energy than existing coal-fired power plants. Energy is captured by the influence of rising and falling waves on two proprietary float designs called the Wave Clapper and Power Wing, which are installed on existing, stable structures. The floats are said to be capable of gathering energy from both high and low waves, which is fed through undersea cabling to a land-based power plant for conversion to usable electricity. Read More

Algal protein provides more efficient way to split water and produce hydrogen

By - December 26, 2011 2 Pictures
Recently, scientists from the Swiss research institute EMPA, along with colleagues from the University of Basel and the Argonne National Laboratory in Illinois took a cue from photosynthesis and discovered that by coupling a light-harvesting plant protein with their specially designed electrode, they could substantially boost the efficiency of photo-electrochemical cells used to split water and produce hydrogen - a huge step forward in the search for clean, truly green power.
