Physicist Stephen Hawking, at a White House lecture in 1999, remarked that if there is no space colonization, population expansion continued unabated and the people of the Earth continued to use power at the rate they did then, then by the year 2600 people would be standing shoulder to shoulder and the Earth would glow red hot.

Susumu Hirasawa (平沢進, Hirasawa Susumu^?, born April 2, 1954 in Tokyo, Kantō region) is a Japanese electropop artist and composer.

In 1972, he enrolled at Tokyo Designer Gakuin College. From 1972 to 1978, he performed in his first band Mandrake, a progressive rock group influenced by King Crimson and Yes. In 1979 he formed a New Wave synth-rock & techno-pop band called P-Model, along with two former members of Mandrake. They released a string of albums through the 1980s, and in 1989, Hirasawa began releasing solo work, while also continuing to work with the reactivated P-Model beginning in 1992. The P-Model project continued until 1999; in 2004 Hirasawa started a new unit known as Kaku P-Model, which is effectively a solo continuation of P-Model.

Hirasawa uses Amiga computers extensively in his work, using applications such as Scala, Bars and Pipes, and OctaMED in the production of his music. One of the factors that set him apart from other Japanese electronic artists is ever-changing production techniques. For 2001's Solar Ray album, his recording studio was powered completely by solar energy.
