How large a 'footprint' or area of the surface of the planet do you think a cube of all the fossil fuel that mankind has ever burned would cover? As an incentive to make you think about it we are offering a prize. If you can find the location, where for a piece of fun, we have 'placed' this mythical cube on this map then Mistral will send you $1,000. A little like those 'Spot The Ball' competitions but with a difference. Don't forget this is about all the fossil fuels that mankind has ever burned and which some claim is now effecting global ambient temperatures, mainly through CO2 release!

Here's a clue. It is 1, yes that's right, just 1 pixel! Please use our feedback form to nominate your geographic co-ordinates (Eg Yakutsk, Russia, 62°5'N, 129°45'E, which incidentally isn't the location, only an example!). Don't forget to leave your name and address. If you are correct Mistral will send you an internationally redeemable Money Order (Western Union) to the value of US$1,000. We will reserve the right to publish your name along with our congratulations (name only, no address).
