Mexican students in Oaxaca City design a motorbike that runs on its own generated energy, without using any combustion. They say their prototype model is a breakthrough invention for eco-friendly motorbikes. Elly Park reports.
What if you could harvest the energy of a moving vehicle to continue to power it? That is the question asked by students of this technical high school college in Oaxaca, Mexico, one year ago. It resulted in this prototype motorcycle called R-Walker created by 17-year-old Victor Garcia. (SOUNDBITE) (Spanish) ECOMOTORBIKE DESIGNER, VICTOR GARCIA, SAYING: "The project is a prototype that generates its own energy as it goes along: As it goes faster and covers longer distances, it generates more energy. In that way, you don't have to charge the battery every 6-8 hours." Garcia calls the process "auto-sustainability." It's based on the principle of converting energy through speed and distance travelled; the engine becomes self-sustaining, generating more than 2,000 revolutions per minute. A battery is used to spark ignition, and afterwards without using any combustion the vehicle can carry up to 110 kilograms and travel at more than 60 kilometers per hour. Co-designer Raul Grajales said R-Walker could bring huge savings for motorcycle users, as well as the environment. (SOUNDBITE) (Spanish) ECOMOTORBIKE CO-DESIGNER, RAUL GRAJALES, SAYING: "With this, we have reduced the use of 200 batteries a day and seventy percent of pollution, because it does not contaminate and has zero emissions and we use one battery every 5-10 years." They built the eco-friendly motorbike from recycled materials, bringing its final price tag to around $200 - a comparatively small sum when considering its potential benefits.
