Although this married couple enjoyed their luxury fishing boat together, it was the husband who was always behind the wheel operating the boat. He was concerned about what might happen in an emergency. So one day out on the lake he suddenly said to his wife, "Ok honey, this is a drill. Pretend that I am having a heart attack. You must get the boat safely to shore."
She was initially surprised and flustered, but she soon settled down and was able to safely drive the boat to shore.
Later that evening, the wife walked into the living room where her husband was watching television. She sat down next to him, grabbed the remote control, switched the channel, and said to him, "OK honey, this is a drill. Pretend I'm having a heart attack. You must set the table, cook dinner, and wash the dishes."

Tidal powerIn 1966, President Charles de Gaulle opened the world's first tidal power station at Rance estuary, in Brittany. La Rance is the most powerful tidal power plant in the world. With its width of 700 metres, it blocks La Rance estuary situated near Saint-Malo (Côtes d'Armor). The operation of the dam is similar to that of run-of-river power plants since its head is also low and there is a substantial flow rate. At high and low tide, the water builds up rapidly on one of the sides of the dam. When the difference in level is sufficient, the gates are opened and the water rushes into the dam. The turbines are reversible so as to be able to operate regardless of the direction of water flow. Each year, the power plant generates 500 million kWh. |
