while aware of the flanders/walloon thing, i wasn't sure which part was which and flemish is better known as an adjective.

I got the impresion that the movement generated electricity which was used for pumping (but I've not read any herbert) - if not, my apologies. If so, then using energy twice like this is wasteful.

on a slow cycle where there was time to discharge before the water turns around - yes (i think i misunderstood you a little)
if there is still charge and you turn it around, yuo are just moving the charge back to where it was.

and if you read Physics.about.com - Generating Electricity with Flowing Water you'll see that the most recent power generation discovery was when Bequerel invented the solar cell (or at least discovered the effect thereof in 1839 - einstein worked out the physics).
if the water is pressurized into a solid canister, you could let it out at a constant rate and get electricity from it.
using it this way means the power plant the runs the water pumping stations really makes the electricity, it just gets stored at water pressure for a while.

I got about 20 emails in 2 hours pointing out the error, so i decided to take the opportunity to update the article all around and port it over to our new publishing tool.
The.6 should be.06, i just typoed a little.

every now and then, somone finds a value that we thought we knew well is different (not this way, I'll grant). So we need to keep measuring at the limit of prescision, because we dont know everything yet.

sorry - I've got no control over the popup factor on my site. We push for less and less everyday, but the mother company has to make enough to keep bread on my table.

no, i dont play guitar - but i was talking about "just" the 2nd harmonic. I know that in many other situations, exciting any higher harmonics solely is difficult.

I think the real issue is the misunderstanding of the word "theory", as opposed to supposition, hypothesis, conjecture or WAG

http://physics.about.com/b/a/040095.htm contains such a map, showing the area of london that would have been pretty much leveled by Fawkes.

You cant break conservation of energy - but you might be able to recylce someenergy wasted in pumping water around. Joe
yes - if the water flows in both directions, half the time it will be undoing the charging effect.

exactly my point in writing it up - I hope your class likes it.

As i wrote this article in January, I dont think this is a good example of quick slashdotting.
Shame that it wasn't an article that I had well proofread (if you havn't seen the mistake by now, see if you can find it)
