Medical freezers chew through a lot of kwh, makes sense to me.
The cells are kept in liquid nitrogen, actually. The cost has a lot to do with back ups, insurance, FDA compliance, inventory management, shipping, etc. As with most things, we can achieve some savings with scale, and I do intend to bring the cost down for all as we can do so. It's our goal to make this available to as many people as possible, not just people with a lot of disposable income.
