Anyone know more about this?

Basically, it's a pendulum on the end of a lever. The claims that this device will multiply input power are extraordinary. Too good to be true? Anyone have any experience with it?

Levers are well understood, as are pendulums. Seems counterintuitive that putting the two together would do something more useful with less effort than working either alone.

Even if this device works as advertised, how could this guy hope to make money from his patent, considering how easy it would be for a potential buyer to just build their own from local scrap?

It also seems like the reaction at the end opposite the pendulum wouldn't be much because all the weight appears to be on the pendulum side. Or, am I wrong about that? Are both sides supposed to be of equal weight? How is this thing supposed to be set up in terms of balance?

There is a YouTube video of this device operating a water pump, should anyone want to see it in action before responding.

To me, it looks like putting less work into the pendulum would also lead to less work accomplished at the opposite end of the lever. Seems like more work could be done more quickly by just manually working the lever without the pendulum..

Anyway, there it is. Has anyone seen or worked with device before?

Just like a morning walk in the country, that link fills my nose with the smell of a cow pasture.

There is nothing new there. As you say, pendulums and levers are well known devices. All he is doing is using a massive pendulum to store the "excess energy" of people that have nothing better to do. Another twist on the PlayPumps idea.

Now if there was a way that passive solar energy could be stored in the mass of the pendulum, well then maybe we would be talking about something.

Putting the best possible light on it, it is a human powered machine designed to match the natural ways our bodies move. So it won't be producing more than the 1/10 horsepower I mentioned earlier. It won't reduce expendable energy usage (at least here in the US) because that oil will come in the form of food. 1 Calorie of food requires up to 10 Calories of fossil fuel input, so any American-human powered machine is at best 10% efficient. Nor will it solve unemployment. If anyone was willing to pay a living wage for humans to convert food into energy of motion, they would already be doing it. In order to out-compete gasoline, one would only be able to pay $0.07 per day. Even most depressed countries are doing better than that.

Which, of course, there is. However, pendulums make terrible energy storage devices, a flywheel is in all ways better, while working essentially the same way.
