<br /> We're sure this comes as a shock to nobody, but here we go anyway: brain swelling is bad. Very bad. That thick, hard skull surrounding your brain is great at providing a good deal of protection, but when things go awry in a big way, there isn't much room in there to let your brain expand.<br /> <br /> Cooling the brain in some manner is apparently a good way to reduce swelling, and a company from the U.K. called Thermahelm has worked up a new motorcycle helmet that incorporates a layer ammonium nitrate and water that instantly mixes in the event of a crash. The chemical reaction will maintain a 37-degree brain temperature, which is said to stave off oxygen loss to the brain.<br /> <br /> According to Thermahelm, its technology will add roughly $250 to the cost of a helmet, and the company is currently working on a retrofit kit that will allow riders to install the system in their own helmets. <a href="http://www.autoblog.com/2009/12/09/video-thermahelm-motorcycle-helmet-is-swell-err-not/#continued">Click past the break</a> to watch a nifty video animating the technology.<br /> <br /> [Source: <a href="http://www.thermahelm.com/index.php">Thermahelm</a>]<p><a href="http://www.autoblog.com/2009/12/09/video-thermahelm-motorcycle-helmet-is-swell-err-not/" rel="bookmark">Continue reading <em>VIDEO: Thermahelm motorcycle helmet is swell.
