Here’s one we hope performs as well as they say. The ThermaHelm helmet could be a life saver for many. It boasts a few lightweight chemical packs built into the helmets lining. One of the packs has water and the other one nitrate. Together, in a sudden reaction, they cause a cooling reaction that can last up to 45 minutes.

That is important because it helps improve the chances of the rider’s survival after a crash, as it stabilizes the temperature of the brain. The ThermaHelm is expected to arrive in July of this year with GPS, a video camera and Bluetooth. We hope this one saves many lives.

A research team at Stanford has developed a refrigeration device the size of a thermos. What’s interesting is that it uses no electricity. Zip. Zero. Nada. Zilch. Instead, it contains some kind of coolant that becomes cold when it’s exposed to heat.

Details are scarce, but the units would be fairly cheap to produce at about $50. The price makes it an ideal way to deliver medicines and cold water to developing countries as well as having a bunch of other uses a bit more noble then your next camping trip. It’s a great breakthrough. All a user would need to cool any given thing is fire, which is readily available.
