Scientists have created a heat-resistant thermal emitter that could significantly improve the efficiency of solar cells. The novel component is designed to convert heat from the sun into infrared light, which can than be absorbed by solar cells to make electricity – a technology known as thermophotovoltaics.
Let’s take a brief moment to travel back in the hybrid time machine to 2010. In late March of that year, Mazda announced it was licensing hybrid technology from Toyota to develop its own hybrid offering, which would likely see the light of day in Japan in 2013.
There’s even more turmoil than usual in the U.S. biofuels policy realm, with lawsuits, demands for criminal investigations, leaked documents and threats flying all over the place.
Mitsubishi Motors, ahead of the upcoming 2013 Tokyo Motor Show, announced plans to showcase at that event two new plug-in hybrid concepts. The automaker to date has mostly been a footnote in the evolving low carbon transportation market, so it will be interesting to see specifics of what these concepts offer as a clue into future green vehicle development.
Tired of living in an analog house? Wish your home would remind you to turn down the heat or know to only do laundry at night when power its cheaper? There’s a new device on the market that just might make your wish come true.
Congress should minimally modify – and not, as petroleum-related interests have increasingly lobbied for, repeal – the Renewable Fuel Standard, the most comprehensive renewable energy policy in the U.S., according to a new paper from two University of Illinois researchers.
I love art that plays tricks on my eyes, making me see something that isn’t there but is. The upcycled ‘Rising Moon’installation created for last month’s Mid-Autumn Festival in Hong Kong is just such a piece of art.
There’s no denying it: most of us depend on electronics in every aspect of our lives. Even if you don’t own that many gadgets, electronics fill the hospitals, police departments, schools, and farms that we count on for valuable services. When these vital electronics die or break, they become part of the 50 million tons of e-waste generated every year.
Vast areas on the Northern Hemisphere are covered by tundra. Here, dwarf shrubs, sedges, mosses etc. thrive on top of permafrost in areas where only the uppermost soil layer thaws during the short Arctic summer.
How much do you know about glass, other than that it’s a pain to clean up when it breaks? Glass is made from a combination of sand, flint, or other silica, thrown together with some fixed alkalies, and in some cases a metallic oxide. Glass is a marvelous substance. It’s the only material that can be recycled indefinitely without losing quality (unlike plastic).
The world of patents is a bit screwy these days, with trolls warping a system that was designed to encourage innovation by protecting and rewarding innovators. Still, it has to be seen as an encouraging sign for renewable energy that the number of patents issued in the broad field has skyrocketed of late.
One of the most controversial issues emerging from the recent Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) is the failure of global climate models to predict a hiatus in warming of global surface temperatures since 1998.
A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment.
Chemists at Boston College have achieved a series of breakthroughs in their efforts to develop an economical means of harnessing artificial photosynthesis by narrowing the voltage gap between the two crucial processes of oxidation and reduction, according to their latest research, published this week in the journal Angewandte Chemie.
Did you know that some research shows just looking at trees improves our health? It’s also been found that just spending time in a natural environment, i.e. in the presence of plants, trees, and animals, can reduce blood pressure and extend our lifespan.
California wants fuel cell vehicles to be part of its ambitious plan to reduce greenhouse gas emissions in the state by 80 percent from 1990 levels by 2050. But right now, across the whole state, there are just nine publicly available hydrogen fueling stations. Clearly this is a problem.
If you have stopped at a gas station recently, there is a good chance your auto has consumed fuel with ethanol blended into it. Yet the price of gasoline is not substantially affected by the volume of its ethanol content, according to a paper co-authored by an MIT economist.
Among the ranks of automakers yet to do much with electric vehicles, particularly here in the United States, resides Kia Motors. That looks to be changing soon though, as the Korean automaker announced recently plans to bring its iconic Soul urban passenger vehicle into the EV space sometime next year.
China, with one of the world’s largest populations, remains a market highly untapped by foreign automakers looking to sell electrified vehicles. General Motors is one looking to change that, holding a workshop recently in Shanghai where it showcased some aspects of its long term vehicle electrification strategy.
Toyota may be singing the praises of hybrids around the world, but it is also tinkering with electric cars as a future low carbon get around town and beyond option. It’s been testing out a concept urban transportation system in its area of Japan called Ha:mo, and now it plans to greatly expand this trial in multiple ways.
