All of us are aware of the high cost of energy these days, as well as the adverse ecological effects of using fossil fuels like petroleum and coal to run the coastal power plants that supply our electricity in Israel.
Since our power plants are located on or near our 200 km coastline, it would be great if someone could come up with an alternative fuel source that is not only economical but environmentally friendly as well. Sitting on the beach near my home in Israel’s central region, and seeing the tides come in, I have often wondered if something might be done to use the power of the ocean waves to make electricity. After all, many countries have been using water power to make electricity for years.
The idea of electricity being generated from the power of ocean tides and waves may be closer to being reality than previously believed up to now. Although harnessing the power of ocean waves has been thought about for years, no practical type of device has been made that is strong enough to withstand the battering received by the power of even normal sea surf as we have along our coastline.
This is the first book I’ve read in a long time that I have felt so conflicted about.
