Of all things, here's an innovation to the seat belt.
In the movies, we've all seen cars plunging into the water and submerging with people trapped inside.
Wired Magazine (11 December 2012) reported on a new escape belt that helps people get out of the vehicles and to safety.
According to the National Highway Traffic Safety Administation, almost 400 people die a year from car accidents that result in accidental drowning.
Now Dutch company, Fijen TMLS has developed a seat-belt that releases when water goes in the interior and dissolves a salt pill in the latch.
The mechanism costs as little as $40 and according to the company's website can "be assembled on all seatbelt releasers in just a few simple steps."
From the pictures of the assembly instructions, I am not sure it is quite so easy.
Also, it is unclear how long the device is good for, since on one hand, their website states that the "Escape Belt lasts 6 months" and on other hand that "the cartridge will need to replaced after 2 years."
In any case, I think the idea is a good one as long as the belt remains secure when not submerged and will not release accidentally with any simple spill or splash. ;-)
