Tidal energy is the utilization of the gravitational forces of the sun and the moon. The gravitational pull of the sun and the moon carry a great deal of energy, which need to be adequately tapped. It is one of the oldest forms of energy.
Tidal energy can be created using a tide mill or a tidal power plant. Tides rise and fall every day in a very consistent pattern. The difference between the tide mill and today's tidal power plant is the size of the unit and the amount of energy generated. Another method of utilizing tidal energy is to build a barrage or barrier with gates of some kind at the opening of a bay or a river system to create an estuary or a big basin.
The most important advantage of tidal energy is its economical benefits, as tidal energy does not require any fuel. Besides the economical factors, tidal energy is clean and renewable, unlike fossil fuels. Tidal energy offers a lot of potential to be a substitute for hydrocarbon and fossil fuels. The advantage of tidal energy has created great deal of tidal energy investment.

...and there was me thinking it was the latest budget version of Red Bull. Thanks Rick, you've saved me from an embarrassing faux pas...
I'm thinking there's a lack of discussion forums for energy physicists.
I recently saw a special program on the National Geographic TV Channel which focused on water turbine electric generators installed underwater in a river channel along with a British Inventor who has developed a "snake like" generator designed to convert the movement of ocean tides into electricity. The documentary covered the problems faced by the engineers in getting these systems to operate successfully.
While we are on this subject, Nicola Tesla made a number of studies and experiments in which electricity was stored in the Earth itself and could be used to power everything from cars to factories. Tesla's dream of free electricity for the people without need for wires, electric bills and meters was not popular with his financier, George Westinghouse, who told him bluntly, "Mr. Tesla, I will let you know when I am ready for your invention of free electricity"!
Anyone ever been to Chernobyl??
I was there awhile ago - and despite it being well over 2 decades since the disaster, the place is still on it's knees.
The whole region would love to talk about alternative energy methods. Those that are able to talk, that is.
Tearjerking stuff up there.
