How much does it cost to make a solar power plant?

How much does it cost to make a solar power plant so it gives off the same amount of power as a Nuclear power plant?

admin answers:

This is a question with several differant answers…..

Depending on consuption if its going on a consuming structure co-generating

or a stand alone generation station. The most cost effective would be a hybrid

thermal/photovoltaic

the thermal would heat a closed contained liquid and make steam to turn large turbine.

$150,000US will get u quite the little generator. $1,000,000US u have a major player

my general rule is $15us per sq ft of heating/cooling space.

I am presently puting together the single largest solar project of its kind. Entire subdivisions of low cost modular homes with the entire roof as the mini-generating station. So if u put up say 400 units. When this hole subdivision comes on line u have a major Generating Station.

Maitaining a plant with no moving parts to wear-out, well except to send some one to clean the panels off once every 6 months wound not be much up-keep……

The panels have 20 to 25yr warrenties and 30yr life

some put up in the late 60’s r still generating.

Michael asks…

could the weight of a boat generate energy?

in other words can you harness the energy from the rise and fall of the tide with a cable tied to a very heavy boat then to a pier generate energy? or used to pull a flywheel or something? would the weight of the boat pulling on the cable be able to wind something or spin a flywheel?
what about the simple fact that the boat lowering down would pull the cable with the force of the weight of the boat?

admin answers:

Yes, and New York has installed them on the bottom of the Hudson River.

In this case they are using the in flow and out flow of the tide to generate electricity. The installation was shown on the Discovery Channel and the first one installed was bent because they didn’t plan on the force being so great.

There are wave generators and have been for a while they use up and down motion of the water to move a piston harnessed to a wheel that turns a generator making electrical energy.

Since the waves always move you won’t have to worry about not having enough windy days or not. The problem is that if you are not careful with the design ti will break too easily. This is using wave motion not tidal energy.

If you wanted to create a tide generator then you should go to the Bay of Fundy (http://en.wikipedia.org/wiki/Bay_of_Fundy), which has over 12′ tides each day.

The tides themselves are not that strong, they are only dependent on the gravitational energy of the moon and the sun. The heat of the sun drives the motion of waves and the winds that energy is more consistent and reliable. A more efficient conversion is to take the energy from the original source (the sun) in the first place. Solar panels are a good example of this and recent work in carbon fibers have increased the efficiency of them, once the price of making carbon nanofibers drops (or the price of energy continues to rise) it will become worthy of mass scale production.

There is an idea to use electrical generators on the bottom of the ocean just off the Eastern shore of North America in the middle of the Gulf Stream. The Gulf Stream is a reliable current that constantly runs and the turbines can be made large enough so that they would move slowly so as to not harm fish. It would be just like putting windmills on the floor of the ocean. The only problem of course is making sure to not let the water get in and salt water is very corrosive. A magnetic induction system could solve that problem though.
