Riding your motorcycle when it's hot brings some dangers with it. Your head become very warm, even hot, in your helmet, and overheated heads is bad, if not unsafe. During hot summers, many accidents happen with motorcycles, and many of them are due to excessive heat build up in your helmet.
Dr Sinnappoo Kanesalingam from RMIT University (Melbourne, Australia) has come up with a novel idea. No, it does not involve placing a fan in your helmet, or using cooling liquids. In fact, he's planning to replace the fabric used inside the helmet with textiles he has been working with. Called Polymeric Water Absorbent Textile, PWAT in short, and Phase Change Materials (PCM), the combination of both materials will lower the temperature inside your helmet by 8 to 9 degrees Celsius. The material is lightweight, nontoxic and environment friendly. The liners can be incorporated in existing helmets without modifying the design.
In essence, the water absorbed coming from your head (i.e. perspiration) is absorbed and evaporated, cooling the head in the process. This way you'll be able to concentrate on your riding skills and traffic, while remaining comfortable.
At this moment, the good Doctor is peddling his helmet liner in Asia, but I'm sure many countries that have hot summers could be interested. "In tropical countries such as Vietnam, Singapore, Malaysia and Indonesia, helmets are often perceived as uncomfortable and restrictive to use, so finding a solution to this problem to minimize head injuries in accidents was important," Dr Kanesalingam said. "I hope my findings persuade motorcycle riders to wear the cooler helmets, which will ultimately result in fewer accidents, hospitalization and trauma and will reduce the cost to society of motorcycle accidents".
