TEDcember Day 04 – Adam Grosser and his sustainable fridge

Today’s talk was another short one, this one about 3.5 minutes. The idea was interesting – a relatively low cost cooling unit that “charges” itself in a cooking fire, then can be used to keep a big drum container cool for 24 hours.

Pitched at storing vaccines away from power, and also preventing food decay and disease it seems to address a need, but (as the comments point out) there are economic and financial issues as well as an apparent lack of progress in the intervening four years. This idea may not be a “go-er” after all. Shame.
