At his 90th birthday science fiction writer Arthur C. Clarke wanted only 3 things: cleaner energy resources, lasting peace in his adopted home, Sri Lanka, and evidence of extraterrestrial beings.
A small gathering of scientists, astronauts and government officials Sunday learned from him that he has always believed people are not alone in this universe. Humans are waiting until extraterrestrial beings "call us or give us a sign. There is no way of guessing when this might happen. Sooner rather than later.
Clarke has written more than 100 sci-fi books, including "2001: A Space Odyssey." His fiction predicted space travel before rockets were even test fired and envisioned computers dominating ordinary lives.
On a different note, he urged the world to consider switching to environmentally friendly fuels.
"I would like to see us kicking our current addiction to oil and adopt clean energy resources," Clarke said.
The British-born author moved to Sri Lanka in 1954 and became a resident guest - meaning he can stay permanently without a resident visa - in 1975. Since then, an ethnic conflict has flared and continues to rage between government forces and Tamil Tiger separatists on the tropical island. More than 70,000 people have been killed in the fighting.
"I have been living in Sri Lanka for 50 years and half that time I have been a sad witness to the bitter conflict that divides my adopted country," Clarke said. "I dearly wish to see a lasting peace being established in Sri Lanka. Peace just cannot be wished, it requires a great deal of hard work, courage and persistence."
Clarke, who has post-polio syndrome and used a wheelchair, cut a cake with "Happy Birthday Sir Arthur" written on it, as Sri Lanka's President Mahinda Rajapakse, visiting astronauts and scientists sang "Happy Birthday." He was knighted in 1998.
Russian Alexei Leonov, who took the first walk in space in March 1965, gave him a medal from the Federation of Cosmonauts of Russia.
"Sometimes I am asked how I would like to be remembered," Clarke said. "I have had a diverse career as a writer, underwater explorer and space promoter. Of all these I would like to be remembered as a writer."
Near the United Nations Glass Palace in New York, there is a metallic sculpture entitled "Evil Defeated by Good", representing Saint George transfixing a dragon with his lance. It was donated by the USSR in 1990 to celebrate the INF Treaty concluded with the USA in 1987
