together for a special event presented by kevin fong at the victoria and albert museum, london. hello, i m kevin fong, and welcome to the engineers: clean energy. we are here at the victoria and albert museum in london with a socially distanced public audience, a virtual audience from around the globe, and three of the world s leading engineers. now, the climate catastrophe threatens us all. but these engineers are at the forefront of providing our world with real solutions. applause. please welcome henry snaith. he s professor of physics at oxford, and through his engineering of low cost photovoltaics, henry discovered thin film solar cells made of perovskite. it could be a hugely significant discovery, as henry hopes it will eventually double the efficiency of solar power and halve the cost. danielle merfeld is an electrical engineer who is chief technology officer and vice president of ge renewables. ge is the biggest creator of wind turbines worldwide, and she and her tea
taking questions, you on afghanistan. carley: doug luzader begins coverage in washington. this reported threat of an imminent attack follows ominous warning coming from the us embassy and that warning said due to threats outside kabul airport us citizens should avoid traveling to the airport, those at the eastgate or northgate, these frenetic evacuations continue but get into the airport has remained a huge challenge for afghans hoping to secure a ticket out of the country and we don t know how many americans remain in afghanistan. state department settled on this estimate of 1500 people yesterday and among them may be a group of families from california. march of this year we spent 19 separate messages, encouraging and urging them to leave the country. there could be others who never unrolled and have not identified themselves to us. evacuation operations at the couple airport have to end relatively soon to the forces enough time to get themselves out ahead of next wee
