Results show that the flow resistance will be decreased and the collection efficiency of the porous solar wall will be increased with a decrease in the inlet air velocity.

计算结果表明，降低空气入口流速，可减小空气流动阻力，提高多孔墙的集热效率；附加玻璃通道的太阳能多孔墙可减小长波辐射损失，并且具有收集热空气的作用。

Eliminating solar soft costs and delays is mission critical for the SunShot to reach escape velocity.

FORBES: Solar Energy CEO Rhone Resch: 'SunShot' is Right On Target

Effects stemming from the Earth's atmosphere, from ocean tides and from the solar wind of charged particles were all found to be too small to explain the spacecrafts' extra velocity.
