Theofilou sits on the "Seatrac" device as his wife Eleni holds onto it to move out of the water, at a beach in Alepochori...Lefteris Theofilou, 52, who suffers from paraplegia, sits on the "Seatrac", a solar-powered device which allows people with kinetic disabilities to enter and get out of the sea autonomously, as his wife Eleni, 37, who suffers from celebral palsy, holds onto it to move out of the water, at a beach in Alepochori, west of Athens July 12, 2013. Founded by a team of Greek scientists in 2008 and covered by European and U.S patent laws, the Seatrac device operates on a fixed-track mechanism which allows up to 30 wheelchairs to be moved in and out of the water a day - all powered by solar energy. In a country with one of the world's longest coastlines and thousands of islands, it has come as a welcome relief for many Greeks, boosting demand each year. Currently, 11 devices operate in Greece and there are plans to expand the network. Picture taken July 12, 2013. REUTERS/Yorgos Karahalis (GREECE - Tags: HEALTH SOCIETY SCIENCE TECHNOLOGY SPORT)
