Cold Vault - The monetization

This fridge would probably have an annual energy consumption of one twentieth modern refrigerators. Modern fridges consume around 450 kWh per year. In LA where it costs around $0.22 per kWh, that comes out to be $100 per year. With older fridges it’s more like $300/year. Replacing an old fridge with one that costs $5 a year to run would save anywhere from $95 to $295 a year. I think the fridge could sell for $2,000 to $4,000. Even without the cool factor, the fridge would pay for itself in as short as 13 years.
