Lightweight Generator From Israel

My god. Now I have to be gender specific

He purrs even when working hard
He's is very economical.

K ?

Jokes always lose something when they have to be explained, but Jewish boys are circumcised on the eighth day. The Abrahamic covenant that goes back 4000 years.

I hate to be forced to ask, but consider me stupid. What does cutting off of something have to do with a potentially interesting generator?

Yep.

Not cut off. Just highly modified.

. I was drinking coffee also when I read your post. On a more serious note do you know why the 8th day is important?

For those of us who have been looking for power generation without much noise, this is very similar to a linear Generator that NASA has developed for power on remote bodies (E.g. Moon/Mars).

They have coupled the power production to a Stirling Engine cycle. Heat is derived from decaying plutonium (which, if memory serves, about 700F degrees.

I went down this path trying to use the water heater on propane to drive the Stirling cycle, and use the water heater tank as a heat sink - as well as to heat the RV.

I eventually gave up because the BTU to watts conversion was too poor compared to a standard generator. Also the prototype was noisy - as noisy as a inverter generator.

It was an interesting exercise though and I learned a lot in terms of mechanical engineering and thermodynamics.

if you Google NASA Linear alternator or NASA Stirling power you'll find the link to the NASA site where they discuss at great lengths power production on remote bodies. None of the linear generators need oil - they use a spring and diaphragm design on linear bearings.

Here is a short video made by the manufacturer:

And here is their video focusing on the technology:

I tried to find out if these things are for sale yet but came up empty.

At 220 pounds, they could be decent built-in generators for larger RVs -- but sixteen KW is more than enough!

I wish they would make a three thousand watt mini version!!

Noticed how much the 2 cylinder motor was shaking the test fixture. The 4 cylinder version looked much less vibration prone, but there would need to be some kind of mechanical linkage between the 2 banks to keep them synchronized.

Interesting concept.

1) the comparison to solar was with regard to powering a vehicle.... not a village. You can't fit a 100kW solar system on a car!

2) where do you get "22 pounds" ?? The 16kW generator engine weighs 120kG !

And further, a 16kW very fuel efficient generator will go far to help a simple village off the grid..... even if they have to truck in a few hundred gallons of fuel every month or so.

Did you even read the link?

never mind
