By Jeremy Webb Ever wanted to see polar bears and whales in their natural habitats? Or visit the sea floor? Now’s your chance to do both. New Scientist has teamed up with Statoil, the global energy company, to offer one lucky winner and a guest the trip of a lifetime: to sail around Svalbard inside the Arctic circle, which is home to polar bears and whales, and to fly by helicopter to the giant Troll platform. From there you’ll visit the bottom of the North Sea. To win this amazing prize, all you have to do is to tell us in no more than 100 words which engineering project you think will have the greatest effect on human life in the next 30 years, and why. Enter the competition: “Win a trip to the high Arctic and the deep sea” You might know of a project already, or have your own idea for a realistic project that should be undertaken. The judges will be looking for ingenuity in both the choice of project and its justification. So what is the next big thing for engineers? Will they build scrubbers to remove carbon dioxide from our atmosphere, create a medical tricorder or harness fusion, the sun’s power source?
