This week there's a report on how India's Space Department is using satellites to find water in a drought. The tell-tale signs of hidden water - such as places where plants grow better than in others - are not always visible from ground level.
Satellite pictures can double the chances of finding the right spot to drill a well. But the pictures beamed back are not just of water sites. They also give a fuller picture of the country's natural resources. Bob Symes tries out the latest nautical inventions. Using a new easy-to-read compass, he navigates the Solent. And he tests a safety gauge that checks how hard the anchor is gripping the sea bed and warns if the boat is drifting onto the rocks.
