Says right in the article that you can recharge it with ice instead of electricity.

  Which is so very stupid. Really? You're going to have someone deliver ice? Instead use an https://en.wikipedia.org/wiki/Absorption_refrigeration https://en.wikipedia.org/wiki/Absorption_refrigeration and deliver fuel - it will be much much lighter for the runtime. Rural places still use commercial units based on this method - you heat part of the fridge in the fire in the morning while cooking breakfast and it will keep it cold the rest of the day.

    As the article states, ice can be delivered along with the vaccines that it is meant to keep cool. So ice delivery is perhaps not so very stupid as it sounds in this case. It can also be recharged if the power comes on for a short while.

      No, it's stupid. Instead of delivering ice with the vaccine deliver a can of gasoline or propane - or even some wood. Much much much lighter for the amount of cold. Storing cold is valuable though, but delivering ice is not.

      1. It's much easier to deliver a small quantity of stable and energy-dense fuel, versus delivering a larger bulky mass thermally-below-equilibrium ice that'll be gradually heating up the whole time. 2. Enough ice for transport doesn't mean enough ice for longer-term storage.
