Like it or not, at least for the near future most of us are stuck with internal combustion engine powered cars. While a lot of hype is behind future cars and technology, from electric to hydrogen to everything in between, a lot of improvements can yet be made on the ICE engine.
To that end, the Department of Energy has awarded GM with $2.7 million to develop a working prototype of a Shape Memory Alloy engine. In theory, this engine could recycle the waste heat and turn it into electrical energy, perhaps one day even replacing alternators and improving fuel efficiency.

There has been a lot of discussion over the last few years about biofuels and whether or not they are actually green, especially when produced on a large, global level.
A new study led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo says no, they aren’t green (when it comes to climate change). However, there are still many important factors to keep in mind before claiming this is the end of a long and complicated discussion.

Because of their enormous body size, whales have been thought to contribute a considerable amount of carbon dioxide to the total greenhouse gas build-up whenever they exhale. However, Trish J. Lavery of Flinders University in Adelaide, Australia claims they – the sperms whales of Southern Ocean, at least – are falsely-accused and that they live quite a carbon-neutral life.
During the October 13 Biennial Conference on the Biology of Marine Mammals in Quebec City, Canada, Lavery talked about earlier calculations overlooking the whales’ capacity to offset their carbon dioxide emissions. The 210,000 sperm whales in Southern Ocean should be declared carbon neutral, according to Lavery. The carbon neutral status is achieved by bringing iron from the depths of the ocean to the surface whenever they feed. This extra iron in the water induces plankton growth which in turn traps carbon and prevents it from being released into the atmosphere.

In a recent international conference on ‘Climate Change: Technology Development & Transfer’ held in Delhi, the Prime Minister of India Dr. Manmohan Singh began his speech by stating that climate friendly and environmentally sound technologies should be viewed as global public goods.
The panel, also chaired by the Maldives President after his country’s recent underwater stunt, called for the Northern countries to do (much) more than just emissions reduction. The statement also comes shortly after media reports suggest India could change its national position on climate change to drop the ‘deal-breaker’ tag put on it by the West.
The BIG question: Will India change its official position ahead of Copenhagen?

Mercury pollution is next on the list of global health threats to face concentrated action with the goal of elimination. According to Zero Mercury Working Group, yesterday the first significant steps toward a binding treaty to control mercury pollution were announced at a United Nations Environmental Program meeting in Bangkok, Thailand, in advance of negotiations that will take place in Stockholm next summer.
The global nature of mercury pollution lies in its ability to travel long distances from its point of emission through the food chain. In fish it accumulates in its most toxic form, methylmercury. Zero Mercury hopes to achieve a treaty by 2013 that promotes more sustainable alternatives to mercury in products and industrial processes, with the broad goal of addressing all controllable emissions of mercury in the environment.

Many of you have heard of Ricardo, a company that has a rich history in Motorsports. However, most of you probably haven’t heard of Recaptured Energy Technologies (RET), until now. The company has just announced a partnership with Ricardo to develop and produce “Green Solutions” to the fuel and emissions problems that plague fleet, commercial and transit vehicle operators.
RET’s basic technology is this: they have a retrofitable hydraulic propulsion system for large vehicles that stores energy in hydraulic cylinders with compressed gas. The vehicle, such as a city bus, then uses that stored energy to give it a boost when starting up. The technology is known as RPS, or Retrofitable Propulsion System, and reduces fuel use by 25 percent and emissions by 25 percent. But before you finish mumbling about how improved fuel economy doesn’t eliminate our dependence on fossil-fuel based energy, this system can improve the fuel and emissions of vehicles using all forms of fuel including ethanol, biodiesel, compressed natural gas, propane and more.
“We like to say that the vehicle is indifferent and fuel agnostic,” said Sam Jones, President of Recaptured Energy Technologies.

An analysis done by Biofuels Digest has come to the very surprising conclusion that an electric car will produce 30% more carbon dioxide emissions over its lifetime than a car powered by E85 corn ethanol. Not only that, the study also found that the same electric car will produce 21% more carbon dioxide than even a gasoline powered car.
These claims assume that 100% of the electricity for the EV comes from coal-fired power plants and that a comparable car would get 35 mpg—both of which seem like unrealistic assumptions. So I dug around the internet today to try and come up with more realistic numbers.

Even as the world prepares for the grand climate meet at Copenhagen this December, a large part of South India has gone under water. And while talks have already begun on coming up with an equitable deal and the very fear that there may be none, over 300 people have already lost their lives while millions are displaced and missing in this global warming related freak weather event, predicted well in advance by the IPCC in its Fourth Assessment Report in 2007.
Mazda, one of the few manufacturers to stay out of the hybrid car craze, has announced they will raise over $1 billion for hybrid research by issuing 315.2 million shares of their stock. As someone who questions the practicality of hybrids, this news is rather disappointing to me personally. You might call me a “hybrid hater.”
But what about hydrogen, Mazda? Le sigh…
Cruise ships lead the pack amongst the world’s top polluters in the transportation industry. If you’re a green-minded person who’s been dreaming of a tropical cruise this winter, but don’t want to lend your support to an industry that is a major polluter, you can reconsider because even cruise lines are trying to go green and do their part to reducing the world’s carbon emissions and overall waste pollution.
