聚光型空间太阳能电站的核心思路是通过特殊的聚光系统,一方面将太阳光集中汇聚到太阳能电池表面,提高光电转换效率;另一方面将发射天线发出的微波波束精准对准太空飞行器或地面接收站的天线。代表方案包括美国的“阿尔法”、中国的“欧米伽”等,其优势在于结构紧凑、重量较轻,但对热管理与指向精度要求高。

Max Rushden is joined by Barry Glendenning, Philippe Auclair and Barney Ronay as Arsenal beat Chelsea 2-1 at the Emirates to maintain their five-point lead over Manchester City. On the podcast today; Arsenal edge past Chelsea at the Emirates. It had lots of things you’d expect. Goals from corners and lots of holding, a Chelsea red card and Robert Sanchez flapping about. Chelsea almost equalised but it’s as you were after Man City’s win at Leeds on Saturday Elsewhere, an agonising VAR check at Burnley as we were forced to look at Ashley Barnes pixellated hand for six minutes, Liverpool hit five at home to West Ham. Jordan Pickford makes an unbelievable save for Everton as one goes in off Barry’s backside. Plus, Igor Tudor says Spurs lacked ‘everything’ which is quite a lot of things - relief for them then that Forest also lost. Manchester United go 3rd with victory over Palace while Wolves win their 2nd game of the season. A lopsided Champions League draw Iran potentially not playing at the World Cup and your questions answered.
