Gоing Sоlаr 1 | One night lаst Mаy, a grоup of people gather around a computer monitor on a 2 | rooftop. They was scientists from the California Institute of Technology (Caltech). The 3 | monitor was linked to equipment that could receive transmissions from a satellite. The 4 | satellite was 300 miles out in space. Around 10 p.m., they’re getting a signal. The 5 | satellite was collected sunlight. On their monitor, the scientists watched as their 6 | equipment turned solar energy to power. “It took it a few moments to sink in,” Ali 7 | Hajimiri, one of the project scientists, says. “Then everyone got really excited.” 8 | The experiment was a success. But it’s just a first step. Eventually, the scientists 9 | hoping to gather the sun’s energy in giant satellites orbiting Earth and beam it down to10 | the power grid. Solar panels in space would produce a constant stream of power. And11 | they would work even when it were cloudy on Earth. “In space, it’s always noon on a12 | sunny day,” Hajimiri says. 13 | “While there are still hurdles to overcome for large-scale wireless energy 14 | transfer of space solar,” Hajimiri says, “this has getting closer.” The biggest obstacle to15 | building solar power stations in space not is the technology. It’s the cost. Launching the 16 | materials are too expensive. That’s changing. Reusing rockets will bring down the cost 17 | of a launch. The end cost of gathering solar energy and sending it to Earth will be less, 18 | and that will make it more practical.
