Energy-Star Deep Freeze Freezer
Cool News Cory, glad it is working fine.
A lot of early freezers, refrigerators and home air-conditioners were very efficient and would easily be awarded the Energy-Star award if they were being sold today.
In the case of Cory's freezer one of the major reasons that it is so efficient is the fact that it is round, and not terribly large in size, the only shape that would have been even more efficient would be a completely spherical ball shaped freezer.
When appliance manufactures first wanted to sell consumers appliances cost of operation was a big concern for people considering such purchases. It was hard enough to get customers to part with hundreds of dollars to buy the appliance, but if was going to cost even a few dollars per month to run that was another matter. You have to remember that the average national electrical cost around the time this freezer was built was around .03 cents per KW, so even in 1949 this freezer would cost a dollar or more to operate most months of the year.
