Electricity-Free Refrigerator

Albert Einstein, a man of great knowledge, invented a refrigerator that did not use an once of electricity in 1930. This model used ammonia, butane, and water. I am not a very scientific person, so don’t ask me to explain it. For more check out the link at the bottom of the page. So what is the big deal? That was such a long time ago, it probably didn’t work. If that is what you’re thinking, you are right. I was not very efficient. The current refrigerator we use now-a-days uses freon gs and electricity. It has been proven that freon gas in the long run causes an effect on global warming. Malcolm McCulloch and a team that he oversees at Oxford University, are using Einstein’smodel, with modifications, to create a more¬†efficient¬†non-electric refrigerator. Their goal is to invent a “greener” refrigerator. McCulloch’s invention is still in the very early stages, and not near commercialization stage. But I may be lucky enough to own one ye tin my lifetime.

Rubber Ducky

I “Stumble Upon”ed this website the other day. Scientists are actually using rubber ducks to melting glaciers and global warming. Who knew a child’s bath toy could become so useful? What NASA researchers have done is place ninety rubber ducks Jakobshavn Glacier between Greenland and Canada. On each rubber duck, in multiple languages, they placed an e-mail address, and the words “science experiment” and “reward.” They hope that people will find these ducks, and inform them of their location. This can help the NASA scientists to track the movement of the water flow from the glacier. They believe that this glacier, Jakobshavn, produced the iceberg that sunk the Titanic. That is amazing that they can figure that out. I am awed by how they chose to use a simple child’s toy for a scientific experiment. They could have spent billions on technical tools to measure and track this glacier, but they save that money. What will they think of next?
