Always have one of these suckers handy:

Most versatile fire tool ever made, plus you'll use it for all sorts of other stuff too. Great for grass fires. Just remember to fight from the black!

Yes, thanks for your candour.

I'm going to lock this thread now since I think we are done.

If anyone has anything has anything else that they particularly want to say, please PM me, and I can maybe unlock the thread just long enough to post it, etc.

Hi and thanks. I still like the idea of using gravity with a mechanical advantage.  Some of the experiments that I tried over the summer revealed a possible configuration that could be fabricated. I...

From the time my cousins & I were tall enough to see over the dash and reach the pedals of a 36 Chevy pickup it was our job to load 55 gallons of home brew Napalm, to fill a WWII flame thrower then ride the fence rows and burn tumble weeds on the range...

Thanks for the honesty.

You were extremely lucky today.
 Burning in a 55 gal drum can be a recipe for disaster if you don't have a cover on it to keep the hot embers from escaping.
Our old burn barrel had a hinged mesh cover, and even with that some of the smaller hottest emb...

Have you thought about getting  a ham radio license? Would give you communications out of that valley, you are probably line of sight to a 2 meter repeater and possibly even an autopatch to make phone calls via the radio.

Never ever burn if there is wind and it is dry. That is a recipe for disaster. And composting that brush and grass makes more sense. Good addition for the garden.

Hi, no bull here. I did a manual test today with really poor results. Based on what I experienced I see no reason to continue this project. My analysis of how this  configuration should work ...

I have some raw land out in WY in the grasslands. The other day I was burning some sage brush in a 55 gal. steel barrel and walked down into a ravine to get some more that was piled up. By the time I walked back within 100' I could see the grass outsid...

The 2nd law is the one that matters here. The phrase "closed system" is important.

Work by gravity is discussed here. http://en.wikipedia.org/wiki/Work_%28physics%29

To repeat what others have told you before GV: a force does not imply power or energy to be had, at least not more than once until you put energy back in against that force to 'recharge' somehow.

Otherwise a static magnetic field would generate energy:...

Reason for experimenting:

No wind, no power.
No day light, no power.
No falling water, no power.
Steam works but in cold weather it becomes a snow machine.

Gravity is a force that is on all the time.
A lever is used for mechanical advantage. Small for...

Hi, it is locked, it is unlocked, nuke it, do not nuke, confused, I know I am

Anyways, I have the PMA wired. I hope to do a manual test today and post some numbers. The main reason for the manual test is to get some idea of how the system will work...
