$140 for a "cooler" that cools 10-20deg below ambient? No thanks. I don't really have any use for that.
They do however show it (or prototypes) in use in some 3rd world type places. That makes a lot more sense to me. 10-20deg for them could certainly help I imagine.
Might have a place in keeping vegetables a reasonable temperature. I've never grabbed a 75 degree beer and though it was refreshing. I'd be interested at 60 bucks.
Also not a fan of me paying double for a product so some third world guy gets one for free. That kind of charity often times hurts more than it helps.
For what most people are used to, I completely agree. Working this hurricane I have to think that a cooler like that would be nice just to keep veggies and stuff for a little longer. Under normal circumstances though, not worth the price. Also, situations like power outages in the US don't last long enough to make keeping that cooler around during the 99% of the time that people do have power.Quote:

Evaporating water pulls heat energy from the inside of the box decreasing the temperature an average of 10 to 20 degrees Fahrenheit from ambient conditions, and even more in dry, arid environments!
I agree - probably good for the right use, but I don?t know that I want it for days in the woods.
Hurricane = high humidity (for quite some time after)Quote:

My focus was more on extended, but still temporary power outages to mitigate food spoilage.
buy a Styrofoam cooler. Throw the top away, take several wet towels and layer them on the top.
Re apply water as needed.
I thought this one was cool, but wouldn't this water be missing minerals? Great for for surviving though.

Yep. I would expect it to be nearly distilled water. It is recommended by some not to drink distilled water. It can strip out your minerals. The biomass part makes it a bit dirty. A bit contrary to the green movement.Quote:
