The hydro-electric dam built to supply energy to China
One of Russia's richest men is planning to invest billions of dollars in a scheme to sell electricity to China.
Oleg Deripaska wants to build a series of hydro-electric dams in remote eastern Siberia and export the power southwards to cash in on Asia's booming economies.
He says the potential market is 60 billion kilowatt hours a year - enough electricity to power Greece.
The BBC's Daniel Sandford visits one of his nearly finished dams, near Kodinsk in Siberia.
