"Clearly our first task is to use the material wealth of space to solve the urgent problems we now face on Earth: to bring the poverty-stricken segments of the world up to a decent living standard, without recourse to war or punitive action against those already in material comfort; to provide for a maturing civilization the basic energy vital to its survival."

Gerard Kitchen O'Neill was an American physicist and space activist. As a faculty member of Princeton University, he invented a device called the particle storage ring for high-energy physics experiments. Later, he invented a magnetic launcher called the mass driver. In the 1970s, he developed a plan to build human settlements in outer space, including a space habitat design known as the O'Neill c

"The increasing demand for electricity, the shortage of fuels on earth, and concern about widespread use of nuclear energy have led to consideration of . ... has studied the SSPS concept, which is the location in geosynchronous orbit of stations converting solar into electrical energy, to be sent down as microwave power for conversion to direct current or to a power line frequency at the earths surface."
"Theres no point in going out into space if the future that well see there is a sterile future living in tin cans. We have to able to recreate in space habitats which are as beautiful as earth-like as the loveliest parts of planet Earth and we can do that."
"We should ask, critically and with appeal to the numbers, whether the best site for a growing advancing industrial society is Earth, the Moon, Mars, some other planet, or somewhere else entirely. Surprisingly, the answer will be inescapable — the best site is "somewhere else entirely."
