A LOVELY BUNCH OF COCONUTS: Tokelau is home to around 1500 people and its highest point is 5 metres above sea level. Pretty much all its fuel — kerosene, gasoline and natural gas — is shipped in from New Zealand. But not for long: solar photovoltaic cells and batteries will take over by next year. And if the sun's not enough, coconut oil will fuel a purpose-built generator. Researchers estimate
that 600 square metres of solar cells and 600 coconuts per day will meet all the power needs. I wonder why wind and marine power don't feature too? New Scientist has more.
