Struggling in the US? Move to China! I graduated from the university with a degree of civil engineering. It is a good field but my heart was not in it. I wanted to be an actor or work in the entertainment industry…living a creative life. My choice of civil engineering was really a mistake but I realized too late. As soon as I graduated, I moved straight to Los Angeles---the home of the film and television industry!
For three years, I tried to get a job in that field. I often worked as an extra in movies and TV shows---standing in the background while actors are in the foreground. This was fun for a while, but I wanted a real acting job, where I was speaking! Sadly, in Los Angeles, there is too much competition. Every race and age is represented: old, young, black, white, Asian and thousands of blondish-red haired Midwestern types like me. Being an extra couldn’t make enough money for me to live in LA. I had to do something else for money.
After three years of trying, I gave up my dream of being an actor and started a different career. I then tried network-marketing, but in the end, that failed. Seven years after graduating from college, I was still in debt, still searching for a satisfactory life. I decided to go back to civil engineering.
However, I was starting to get very disappointed with my life. Why is life not like what I expected? I expected to have made a lot of money, gotten married, with a house and nice cars, kids, time freedom, etc. Millions of people lead lives with their dreams shelved, existing but not really living. I want to my life to be different, more satisfactory, more alive. America was not providing that for me.
In addition, America was too expensive---always worrying about money was a headache. I wanted a life with adventure, romance, friendships, successes, and dreams realized.
I decided to move to China.

An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.
We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon, which is far more damaging than carbon dioxide.
Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.
His team has completed a model machine of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.
Einstein’s idea uses butane (a gas) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.
“If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you’re at sea level and that’s because the pressure is much lower up there,” said McCulloch.
At one side is the evaporator (蒸发器), a bottle that contains liquid butane. “If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so,” says McCulloch. “That’s what makes it cold.”
The gas fridges based on Einstein’s design were replaced by Freon-compressor fridges partly because Einstein’s design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to greatly increase the efficiency.
However, McCulloch’s fridge is still in its early stages. “It’s very much a model machine,” he said. “Give us another month and we’ll have it working.”
