Toekomstmakers, a Dutch television program, showed today in its broadcast the water turbines of Tocardo. It is an example of alternative energy sources besides sun and wind, where the energy difference between low and high tide is used for electricity. Managing director Hans van Breugel is interviewed and you can see the testing model in the Afsluitdijk that they call a “giant dynamo in the water”. Missed it?
