CBBC - Climate Change: Ships could use wind power to sail again
When most people think of sailing ships, they think of cannon filled boats and pirate ships from centuries ago.
But some scientists in the UK haven't been thinking of them as something from the past, but as the future instead.
They think new hi-tech sails could be fitted to ships to help them move without using as much fuel and be more environmentally friendly.
Scientists in Southampton have just been given some funding to do experiments to see how well they will work.
