Today, many motorcycles are equipped with engines that are powered by gasoline, a fuel that contributes to the air pollution and greenhouse gasses. A new hope comes from two Indian scientists that have developed a cleaner motorcycle engine that is able to generate enough power to run a motorcycle for up to 40 minutes, by using compressed air to turn a small air turbine.
According to the researchers, if this technology will be widely implemented, mostly in areas where motorcycles are a major source of public transportation, it could cut emissions substantially. As they describe in a recent issue of the Journal of Renewable and Sustainable Energy, traditional internal combustion engines could be replaced with a combination between their design and a compressed air cylinder.
Bharat Raj Singh, a researcher at the SMS Institute of Technology in Lucknow, India and one of the two authors of the paper said that if their technology will be implemented, 50 to 60 percent of present emissions in some areas could be reduced. The only problem is the building of a high-capacity air tank to store sufficient “fuel” for long rides. They must design a new tank because the existing ones would require someone to stop about every 30 km to swap it with a filled one.
