加拿大透特科技公司近日成功申请了“太空电梯”专利。根据设计和建造方案,太空电梯将高达20千米,届时宇航员和运载火箭都可以先搭乘太空电梯进入位于平流层的发射平台,然后再点火起飞进入太空。透特科技公司科学家表示,未来太空飞行的花费将会减少1/3,因为航天飞机等飞行器不再需要携带大量的燃料以助自己从陆地起飞。太空电梯发明者布伦丹·奎因介绍说,“宇航员将通过太空电梯升到20千米高的平流层,并从那 Tote Technology Canada recently successfully applied for ”space elevator " patent. According to the design and construction plan, the space elevator will be up to 20 kilometers. At that time, astronauts and launch vehicles can take the space elevator to the launching platform on the stratosphere and then take off to space. Totech scientists say the cost of spaceflight will be reduced by a third in the future because spacecraft and other spacecraft no longer need to carry large amounts of fuel to help themselves take off from the land. Brendan Quinn, the inventor of space lifts, said that astronauts will travel through space lifts to the 20-kilometer high stratosphere and from there
