Dhiraj Singh/Bloomberg via Getty New Delhi — When the COP27 United Nations climate conference kicks off this weekend in Egypt, India will likely approach the international gathering with a well-earned boast about its success in going green and an appeal for more help to continue down that path. But despite significant strides that one analyst says have made India the only nation with anything to brag about, it may find an international community with little appetite for generosity. Ahead of the climate summit, and clearly aiming to impress, India has set itself tougher t...

China tests technology that could beam solar power from space to Earth

Chinese researchers have successfully tested a full-system model of technology that could one day wirelessly transmit solar power from outer space to Earth. A model power station at Xidian University in Shaanxi province captures sunlight high above the ground and converts it into microwave beams. It then transmits through the air to a receiver station on the ground, where it can be converted back to electricity. While the model only sends the energy 55 meters through the air, the researchers hope the technology could one day be expanded to send power from orbiting solar panels to Earth. The research team behind it recently c...
