The scaled models will be tested at the United States Navy's large indoor testing pool near Washington. Machines at the pool can create ocean-size waves. Mr. Zayas says the models will be tested to show how much ocean wave energy they can capture. The competition will not require the machines to produce electrical power. He says changing the mechanical kinetic energy into electrical energy is easy.__________________________这个比例模将会在华盛顿附近美国海军的大型室内游泳池里进行.池里的机器能造出海浪大小的波动.Zayas说,该模型将被测试看看到底能吸收多少海浪能量. 此次比赛不需要机器发电.他说,机械动能转化为电能是非常容易的.__________________________
