Efficiency
Researchers in Japan have developed a new material that allows solar cells to generate an amount of energy from sunlight that was previously thought impossible. The discovery, made by a team at Kyushu University, involves a special “spin-flip” emitter that can harvest energy from the Sun that is typically lost as heat. The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of 130 per cent – opening up new possibilities for ultra-efficient solar panels.
The problem of waste that really needs fixing is not the public employees but the private contractors—and Elon Musk is one of them.
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated.
