Should evolution be taught in high school?

There are 180393 comments on the www.scientificblogging.com story from Feb 24, 2008, titled Should evolution be taught in high school?. In it, www.scientificblogging.com reports that:

Microbiologist Carl Woese is well known as an iconoclast. At 79 years of age, Woese is still shaking things up. Most recently, he stated in an interview with Wired that...

"My feeling is that evolution shouldn't be taught at the lower grades. You don't teach quantum mechanics in the grade schools. One has to be quite educated to work with these concepts; what they pass on as evolution in high schools is nothing but repetitious tripe that teachers don't understand."

If that person is near a large pond or lake above him/her also, a siphon can produce energy for him or her.

I won't reiterate the points that have been made already, but you somehow seem to feel this would all be 100% efficient and free. That would not be the case.

It could be more versitile because the outlet can be positioned anywhere you need it to be, as long as it is below the inlet.

Don't you think it would be easier and more efficient to convert the water to energy at the source than piping it all over creation??? Energy would be easier to move than water, putz. That's why they don't build hydroelectric dams in the middle of a city rather than on a freaking river!

Right, like creationists who think they know everything about evolutionary theory, yet demonstrate abject ignorance of the subject when questioned about it. Your Bible quote, which essentially says "everybody who disagrees with you is stupid, so don't get upset if people tell you your religious beliefs are nonsense," isn't evidence of anything except apologetics and rationalizations...the same kind used by cults throughout history.
That you could infer from anything I have written that I think those who don't agree with me are stupid, just shows how unreasonable you are. Reason, look it up. Now I know why you people continually call each other dishonest. You can lie by deliberately distorting what someone else has said.
Seems there is a lot of that that goes on here and it "kinda does" make everyone look stupid.

At times water may not be running from an overflow of a pond or lake, a siphon will run as long as there is water over it's inlet.

So you are proposing that a siphon be used to create a flow of water beyond a natural or man made dam in a body of water. Then this flow can be converted to electricity with a turbine. The electricity can be distributed to wherever, to do work.

Now isn't this what is done to create hydroelectric power? Without using a siphon of course.

As I said, it can be used anywhere water is, as long as there is enough of it and there is a drop in elevation between the inlet and the outlet.

A) That swoosh was what I said flying over your head.

B) And, no, the water will run so long at the water as the inlet is *ABOVE* the outlet.

Wrong.

Were does the energy come from to start water flowing?

Where does the energy come from to keep the water flowing?

Where does the energy come from to raise the source water above the height of the outlet?

I have been doing some reading on the subject of siphons which seems to be the failing of Free Servant and Jim. They come up with some idea and never bother to hit the books to see what has been done.

From my reading it sounds like you would have to have a great elevation between the source reservoir and the outlet in order to overcome the cost to run a turbine and a generator to make it worthwhile.

Servant is talking about larger scale, but he doesn't seem to be thinking large scale.

As I stated in a response to Mike, I have been doing some reading and it sounds like it couldn't be just anywhere there is a difference in source elevation to outlet elevation. It sounds like there is a minimum difference and it would vary depending on demand and the number of turbines and generators used to convert the mechanical energy to electricity.

In addition, if your siphon overcomes the replacement rate of water into the source, you will run out of source and thus your supply of electricity. As you stated siphons can drain ponds and lakes. This free electricity is starting to sound more and more like the electricity I am paying for now.
