recorded with solar energy. To reduce carbon emission, Studio WIRESELF was outfitted to be powered completely by a photovoltaic system of 2 solar panels, with 2 car batteries to store extra energy. Years later, Hirasawa added 2 more panels to the studio and retired the batteries. Initially Studio WIRESELF operated on large pieces of equipment, both analog and digital. With the advances of technology and the streamlining of production under Hirasawa Energy Works, the working landscape transitioned to software synthesizers, with the physical elements of the studio reduced to one recording booth and two workstations, one for Hirasawa and the other for engineer Masanori Chinzei. Activism and charity In 1988, Hirasawa sold a at a flea market in Yoyogi for charity, it contained 3 New Age songs made specifically for the release and came with a 36-page long booklet chronicling the self-analysis of his dreams and reality. All proceeds were donated to the volunteering welfare facility for the mentally ill in Gunma Prefecture, founded by the psychologist who gave Hirasawa counseling around the time he made the P-Model albums Scuba and Karkador. In 2001, a pregnant stray cat appeared in Hirasawa's studio. He took care of her and helped carry out four of her pregnancies from 2001 to 2002. Since he could not take care of all the kittens, Hirasawa created a temporary site to recruit possible adopters and keep up with the welfare of the various cats. As Hirasawa objected to the American response after the September 11 attacks, which he believes involved excessive carnage, and the Japanese government's aiding of such actions, he offered downloads of online banners and two of his songs for free, which he hoped would be used as tools of objection. One of them is a rerecording of 1994's "Love Song", which is about children in the battlefield; the other is "High-Minded Castle", about a man who "can not know the truth and true background through media, he tries to face the real tragedy on the other side of the world". The latter was taken from the Blue Limbo album, which displays a dystopian theme partly influenced by the American government's retaliation. To support freelance journalists, independent and citizen media, Hirasawa started a free music archive to be used by independent news as background music. He sent e-mails to various associates and members of P-Model requesting involvement, the only one to join was guitarist
