Dust Off those Notebooks — Treasure Abounds

It is amazing when one considers how the very technology needed to save our world from utter destruction might indeed be fifty or more years in the past.

For instance there’s the Stirling Engine patented in 1816 by Robert Stirling who pretty much had no idea how the thing worked, only that it worked. Amazingly, it ran off of heat alone. “it can be driven by any convenient source of heat.” It’s only recently that intense investigation and testing of this technology has occurred.

Most recently, we have a “new” type of refrigerator developed by Albert Einstein and his student Leo Szilard in 1930 which requires no electricity or moving parts.

“Malcolm McCulloch, an electrical engineer at Oxford, is trying to bring Einstein’s refrigerator back. McCulloch explains that the design is environmentally friendly and could prove especially useful in developing countries, where demand for cooling appliances is quickly increasing.”

The usefulness of such a device in our current landscape would be incredible, not to mention the endless benefits for countries in sub-Saharan Africa where electricity can be hard to come by. The ability to refrigerate food would not only help in the storage of food items, but also in the health of the people who often eat unsafe food. Refrigeration is just the thing needed to curb Cholera, Typhoid, Giardia and Amoebic or Bacterial dysentery in these developing countries.

If Einstein was able to throw that together using 1930’s technology, imagine what could be done today.

Low-Cost, Electric-Free Refrigeration Drops in Temperature and Price

Empowered by computational fluid dynamics Adam Grosser of Foundation Capital has spearheaded an effort to build a refrigeration device for the billion+ people who currently have no access to electricity. The break-through approach combines water, ammonia, heat and a little bit of know-how to create a low-pressure, non-toxic refrigerator capable of cooling a 3 gallon container an entire day in temperatures up to 30C.

Here’s the video of his short and sweet TED presentation:

Grosser expects that such units can be manufactured “at high volumes for about $25”, a feat that would enable the better transport of sensitive medicines, foods and materials through developing regions to the people that desperately need them. Such a device could play an important role in the betterment of countless lives as it gives people some more low-cost control over their immediate environment… not to mention keeping beer cold on extended camping trips (a win-win proposition that will hopefully help foot the development bill)...
