Tips for living the abundant life

Are the Scottish God’s Frozen Chosen??Where would the Canucks and the NHL be today without artificial ice? Where would Coca-Cola and Pepsi be without the ice-cold ‘pause that refreshes’? Where would your family dinner be ‘at’ without your trusty kitchen fridge? How easy it has been for humanity to produce heat by fire. Yet we have quickly forgotten how hard it has been for humanity to produce cold by any means.
The earliest method of refrigeration was the storage of food in caves and cold springs. This method of storing food in cold places slowly changed, as people began keeping food in their cellars, in their outdoor window boxes, in the snow, or underwater in nearby lakes, streams, or wells. For most of human history, perishable food have been preserved by drying, smoking, pickling, heating, and icing.
The ancient Romans were as fond of putting ice in their drinks as we are today. In the 1st Century AD, no Roman banquet would have been complete without the provision of lavish amounts of ice or snow for guests to put into their wine goblets. The famous Roman philosopher Seneca condemned snow-shops and ice-cold drinks as a clear sign of ever-growing decadence. The Roman emperor Elgabalus used donkey trains to transport a literal mountain of snow to his hot summer villa: an early form of air conditioning! Mideastern Sultans used their camel-driven postal system to transport snow all the way from the Lebanese Mountains to Cairo, Egypt. In the early days of the British Empire, perishable Norwegian ice would be sent 8,000 miles around Cape Good Hope to colonies in India.
The invention of the icebox led to more efficient refrigeration. Ice was delivered to houses by the IceMan, and was used in wooden iceboxes that were lined in tin or zinc and insulated with sawdust or seaweed. In 1868, ice blocks cost 5 times more per pound than first-quality beefsteak. By 1890 the U.S. was exporting 25 million tons of ice cut from her northern lakes.
The irony of artificial refrigeration is that some of its greatest breakthroughs came in the chilly land of Scotland. From 1750 to 1850, Scotland was the world center of scientific and engineering thought. It was in 1748 that William Cullen of Scotland demonstrated that the evaporation of ether in a partial vacuum produces cold.
Ninety years later in 1837, James Harrison, a Scottish journalist, moved to Australia from Glasgow and set about designing his own refrigeration machine. What is it about the Scottish that spurs them off to create technology against such impossible odds? Click to find out more….
