The helmet will be sold for around $480 by the British creators in May. The ThermaHelm is a carbon fibre helmet that contains twoo packs, one filled with water the other ammonium nitrate. On a sudden impact the packs break and the solutions mix to form a cooling solution that lasts for around forty five minutes. This will keep the brain cool and help to increase the chances of survival in a serious accident.

There has been a huge response to the idea says the inventor Jullian Preston-Powers with inquiries world wide and he is also looking at other uses for his invention. One option is to use it in military helmets.

There is also a more expensive version available that includes extras such as Bluetooth connections, GPS and video and will retail for around $800.
