Perpetual Motion Machine: Any Flaws?

10/11/2017 10:22 AM

It's so simple I can't believe none of you thought of it!

Does this also work in Australia?

It would run counter clockwise in Australia.

If you turn it up side down does it run backwards?

No, then it just runs counter-intuitively.

It has to be overly complicated to work properly...

I tried it with "8", but when one weight got to the bottom, it crashed through the floor and disappeared through the bedrock underneath the house!

Your quote says it all...Homer certified.

Actually there is a thing like this, that has weights in slots on a wheel, and it arranged such that the moments of inertia change from the left side of the wheel to the right.

Somehow it manages to rotate, but I cannot certify for how long, and certainly with no particular output above its own requirement.

..."certainly with no particular output above its own requirement."...

I'm thinking somewhat less than that...

...well now, but then we could not call it perpetual, could we?

I mean it could last and spent perhaps a thousand years...if only microbes has to used the energy it took from that one.

Speaking of microbes, or rather bacterial spores, here's this update, likely to provide a significant fraction of renewable energy after the apocalypse is done.

Really, really interesting, but more work to do on durability, resiliency of the spores.

This is pretty intelligent design work, and will exceed other chemical battery energy storage, and meet the grid price point.

Perhaps Leonardo lived before the Law of Conservation of Energy was enacted...

If you want perpetual motion for all practical purposes, just put a chunk of radium or plutonium inside a Stirling Engine. It's not perpetual, but it will run for a really long time.

The half-life of Pu-238 is 87.7 years, so I reckon it'll outlast your average Energizer Bunny!

Finally a perpetual motion device that I can't argue with.

The humor of this lasts for about two seconds--and then deserves a Darwin award.

Good! I learned from my daughter, The Stewarts of which I am a part were apparently chased out of our motherland (Scotland), and went over the water to Eire an. Later, we made it over here this side, and made our slops patriotic contributions here.
