[RE-wrenches] Energy Storage Equipped Appliances

[Steve McCarney]

Hi

Since battery reliance brings it's own set of challenges there have been
some products that have used built in storage that is battery free.

Fridges can be found that use ice in the walls and/or top to store cool.
So no battery needed.  Mostly used for DC clinics where vaccines are stored
but Sundanzer may have some that are more domestic oriented.

Another energy storage "appliance" are pumps that can use stored water as a
way around the battery.
