Refrigeration.
Technology has moved on with the CFC being removed from the gas that operates to cause coldness, but not all freezers are designed to produce ice. Many today are just to keep fruit and vegetables cool for long term storage.
The problem of re-freezing remains a danger and nothing as yet has been discovered to do this, but time will bring in new ideas. Refrigeration is not just for food and flowers, but also for organ transplantation and many other medical uses.
Some people even pay a lot of money to be kept frozen after death in the belief that one day a cure for terminal illness will be found to bring them back to life?

Freezers. Part-One.
Advancement for Humanity.
The ability to freeze goods has given the world a great advantage, perhaps one of the biggest in human history.
Today we have freezers on aircraft, shipping, fishing trawlers, factories and trucks both road and rail cars. Meanwhile various types of goods from meats to flowers can now cross thousands of miles and arrive fresh the same day.
Prior to the invention of the refrigerator ice and cool boxes were it and food could not really be moved very far or kept very long. Flowers really had to be picked fresh and many other things eaten with in at least 24 hours.
