Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.

Traveling by train is usually not easy in China. It can be hard to get a ticket. When you’re traveling to the railway station, you look at your watch, for you are afraid you will miss your train.

But there is good news for people traveling between Beijing and Shanghai. Construction (建设) on the express railway (高速铁路) between the two cities started just before the Spring Festival of 2008. When it is finished by 2013, taking a train will be as easy as taking a bus.

“There will be trains every several minutes. Buying a ticket, getting through the checkpoint (检查站) and taking your seat, will take just 10 minutes,” said an engineer.

There may be high-speed trains running at 350 kilometers an hour. The travel time between the two cities will decrease from 10 to about 5 hours. The trains will carry twice the present number of passengers.

The new line will be 1,318 kilometers long and go across specially built bridges. It will run along side the present line. There will be 21 stations in Hebei, Tianjin, Shandong, Anhui and Jiangsu.

“The cost of traveling by the express railway may be around 800 yuan. That will be more expensive than an ordinary train, but cheaper than by air.” Said Zhang Xiaoling, a Jiangsu government official.

According to Zhang, the higher price is caused by the large cost of the railway project. At about 200 billion yuan, the project may be even more expensive than the Three Gorges Project (三峡工程).
