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.

Look at the paper in the picture
carefully. Is there anything different from your notebook paper? This kind of
paper feels as soft as your notebook paper. It’s also easy to write on. But do
you know, this kind of paper is made from stone?
As we know, stone is easy to get on the earth, so it’s cheap. And the stone paper is about 20% to 30% cheaper than ordinary paper. The stone paper causes little pollution and helps protect the environment, because it makes tree and water free. The following table shows what is needed to make one ton of stone paper and one ton of ordinary paper.
