    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!
