While solar power satellites have been discussed for many years, what is different this time is the idea that this could replace the need to transport fuel into war zones and other dangerous places, saving both lives and money. This latest proposal may jump start efforts to make this concept a reality.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
