He was certainly a few bricks shy of a load.
One way of getting banned is to tell everyone in a post you are going to his representative in Congress and make the forum (WWT) responsible for the "stalker" and that the Mods would need to vet and verify the identity of all members.What was the final straw in getting him banned? He came across wrong, but pretty sure he meant no harm.
They HAVE been built, and there are a few non-obvious problems with them (that is, non-obvious if you don't think about the device for more than a few seconds...)Why couldn't you make a device that uses the incoming and outgoing tides to harness the power to generate power. Kinda would be free and "green"...
That is true, but.... the efficiency of an unshrouded set of blades is rather low.. Remember: a turbine works by removing energy from the working fluid: be it a gas (air, for example, or steam, for another example) or liquid: i.e. water. It is important to control the flow of your working fluid past the "blades", whether they be fan blades or a paddle wheel of some sort.After thinking about it for 25 seconds, my idea would have no inlets to get clogged with debris. More like a water wheel or a wind mill vane type thingy .... but I know nothing.
