Heated wetsuit warms you sans the smelly mess
Using two rechargeable lithium ion batteries, a titanium heating element on the back of the wetsuit lets you bring the internal temperature up to 51 degrees Celsius.
Diving is a great sport. But once you go deeper than 65 feet, it can get really cold even in tropical waters. Wearing a thicker wetsuit may help, but this causes buoyancy adjustments and, frankly, isn't really all that effective. One trick I learned from experienced divers (and which I stumbled upon purely by accident and a lack of bladder control) is that pee is a great way to instantly warm yourself. Sure, you stink when you get out of the water, but think of all that nitrogen you are returning to the underwater ecosystem. Just be sure not to let your dive shop know that you let yourself go in their rented wetsuits.
Disgusting you say? You can shell out $1,000 for the Rip Curl H-Bomb then. Using two rechargeable lithium ion 7.4-volt batteries, the titanium heating element on the back of the wetsuit lets you bring the internal temperature up to 51 degrees Celsius (124 degrees Fahrenheit). The 3/2mm-thick suit (3mm neoprene for torso and legs, 2mm neoprene for arms and crotch) has three heat settings for different environments.
Cost notwithstanding, somehow I feel as comfortable wearing this suit in the sea as taking a toaster to a saltwater bath. So thanks, but not thanks. I'll stay with nature's solution, which won't set me back $1,000.
