A compact lens could make high-speed Internet access commonplace on trains.
Internet access can make a train trip far more productive and enjoyable. But train-mounted satellite dishes that send and receive data can't be used on a lot of routes, as the standard hardware is too big to fit in some tunnels. Now researchers at the University of York, in England, have developed an alternative: a dome-shaped plastic lens that's less than half as high as a typical satellite dish. The system, which was developed with funding from the European Space Agency, is also designed to track multiple satellites at once, making it more reliable than a dish.

R2-D2?: No . . . it’s a dome-shaped lens that collects data transmissions from satellites. The researchers at the University of York who designed the lens say that it’s small enough to be mounted on a train--even one that has to travel under low bridges and through narrow tunnels. At 30 centimeters, the lens is less than half the height of satellite dishes used today. Credit: John Thornton and Andy White, University of York, U.K.
