Geothermal got some instant karma with the dedication of the geothermal-powered Imagine Peace Tower in Iceland on what would have been John Lennon's 67th birthday.

Lennon's widow Yoko Ono, who created the light sculpture, unveiled the tower this week in Reykjavik.

"I thank the people of Iceland, for having given so much love to this tower from its inception. Imagine Peace Tower was visualized with love, and realized by love. It is a gift from the people of Iceland and me to the world," said Ono.

Ono said she chose Iceland for the memorial because of its beauty and its reliance on natural power.

Bearing the inscription "Imagine Peace" in 24 languages, the tower is powered entirely by electricity from the Hellisheidi Geothermal Power Plant.

The sculpture will light up the sky in Iceland's capital each year from Lennon's birthday on Oct. 9 until Dec. 8, the anniversary of his murder in New York in 1980.

The tower, which was constructed in Japan, is on a small island in Reykjavik harbor.
