Searched for but found nothing, sorry if it's discussed elsewhere!
For those that never heard of it, a Peltier device is a small (40mm x 40mm x 4mm) and
cheap heat
pump that uses electricity to transfer energy between two ceramic plates. It's used in aviation and
boating industry as
cooling element in
electric fridges, heat being dissipated by a huge cooler and fan. I recently got my hands on a 50 liter broken fridge I could fit such a device in, I got -5 C from +10 C in 30 minutes using a 60W device. Currently available from
China are 60W to 231W versions.
I'm thinking of two
tanks having one to many devices in between. With a max 70 degree Celsius difference,
water can not be used for the cold side, but an automotive
coolant running thru a
freezer is easy job.
Anyone thinking about something similar?
