Two men were sitting together in a plane. They were on a long journey. One of the men was a businessman. The other was a farmer. They sat without talking for a while, then the farmer said, “Let's do something to pass the time.”

“What do you want to do?” the businessman asked. “We can ask each other riddles,” the farmer said. “OK. Let's make rules first,” the businessman said.

“If you don't know the answer to a riddle, you pay me$100. And if I don't know the answer, I'll pay you$100.”

“That's not fair (公平的). You are a businessman with much knowledge. You know more things than I do. I am just a farmer,” the farmer said.

“That's true,” the businessman said. “What do you want us to do?”

“If you don't know the answer to a riddle, you pay me$100. And if I don't know the answer, I'll pay you$50,” the farmer said. The businessman thought about this, then he said, “OK. That's fair. Who will go first?”

“I will,” the farmer said. “Here is my riddle. What has three legs when it walks, but only two legs when it flies?”

The businessman thought for a long time and said, “Mm, that's a good one. I'm afraid I don't know the answer.” He gave the farmer$100, then he said, “Tell me the answer.” “I don't know,” the farmer said, then he gave the businessman$50.

At most schools, “going green” means bringing out less trash or trying to recycle. But at New York’s Riverdale Country School, it means asking kids to run and even jump in the hallway. That’s because on January 7th, 2014, the school became the first place for the floor tiles(瓷砖).

The tiles get energy made by the kids and turn it into electricity that can be used for classroom lights, science projects. The first US installation(安装)of eight tiles near the school’s student center thanks to 14-year-old Zach Halem, who tried to ask the officials to buy them.

Besides providing fun green energy, the tiles also serve as a learning tool. Every time a student walks on one, a screen will show how much energy was generated(产生). It makes kid feel proud because of saving energy.

Made largely from rubber and other recycled materials, the tiles that have been around since 2009, are the idea of 26-year-old British Industrial designer Laurence Kembell Cook. While new to the US, they have been installed in many places in Europe-from a London underground station during the 2012 Olympic to a street in Paris.

However, it was not until PaveGen started getting popular in London schools that Laurence realized that his invention not only saved energy, but was also fun!
