When I said tabletop, I meant On top of a low table. Of course the stove needs to respect the basic rules regarding dimensions for a rocket. That wasn't my question.

Thanks for your contribution. But that's much too large and complicated.

Looking for a good brick rocket cooking stove plan with specific criteria.

It needs to fit on a table top and be indoors, so it has to be relatively small.
The best I could find is just an image with no info.
I don't know enough about this to guess how the back section is built.
It will be used in the Philippines where everybody cooks with an open fire indoors.
Venting doesn't seem to be a concern but at least a rocket makes things less smokey.
I like the j-tube idea for a self feeding fire, but I'm not sure the cooking surface would be very hot?
This image with the L-tube seems pretty good. All things being equal, Would the cooking surface at the top of the riser be hotter with a J-tube or L-tube design?

The available information online about taking biogas (from a bio digester) and using a compressor to transfer the methane from a "bag/rubber membrane" to a propane cylinder is sparse and sketchy at best. At least what I can find anyway.
Has anyone here done it before?

All I can find are videos like this.

And another where a guy uses a fridge compressor.

Thanks everyone for your time, the education and contributions to the discussion!
I now understand that the condenser tubes make my idea impossible.

Here's a follow up question. I can't find anyone online that has ever built there own chest type fridge (plywood shell, a ridiculously high R value walls, salvaged condenser tubes, etc) with components from an old freezer.
I'm not asking if it's worth the effort, but only if it's possible just to see how far we can take the energy efficiency?

Has anyone built their own fridge out of an old chest freezer that was more efficient and  cheaper than a Sundanzer? (for example)

I'm thinking of doing the "old freezer to fridge conversion" I've seen online to be used in the tropics, but I'm thinking of taking it a couple steps further.
1. Cut the freezer in half horizontally.
    - the normal depth of a chest freezer isn't practical for daily use. I'm thinking if it were half as deep, it
      would require less electricity and provide easier access to what's inside.
    - so I would take a skill saw to it all around to cut it down to size then reattach the lid?
2. Increase or even double the insulation.
    - I always wondered why there aren't manufacturers out there who haven't done this?
    - I would remove the outer shell of the chest freezer and just double the thickness of the insulation (especially on the bottom and side walls) to increase the r value and again reduce energy consumption.

It would ultimately be used in the Philippines on a solar system.
Any thoughts? Has it been done before?
