This looks too good to be true. I may order these and test them, then do a YouTube 'review' video. The 1200 mWh converts to 660 mAh.
Check out the whole ad listing.
update: reviews are mixed.

Mechanical - Gravity etc. / Re: Gravity Storage

Just seen this video.
I originally thought that this was an awesome idea, then started thinking about it. I thought it would only have to raise the weights once but then I though what happens when the rings of blocks get to the bottom? What happens when all the rings get to the same height?

Then you have to start stacking them all up to the top again.
It is great for storage  of power though, but not as great as when I originally posted this.
UPDATE>>>>>>>Oh I see: At 2:02 you can see they take blocks from the top of the outer ring and move them up higher to the inner ring. Wonder how that software program works?

Watch the vimeo video.

I closed that business.  :-)

Lol
I think Caleb Engineering ought to do consulting.

I'm getting to that point where I don't know whether to retire or not (turned 58 this year).  The kids still keep me busy and I don't think I could work full time, but they are getting older ( 13 and 15 ) and can handle themselves more.  My wife thinks I ought to look for part time work, but I don't know if anyone wants a part time engineer.  I would like to work around other people instead of working from home.  I've been out of industry for so long, I don't really feel like teaching.  I'd like more recent practical experience.  Anyhow, that is probably too much information.

I remember that project.  I would have liked to see it run.
You're still teaching me. ;D

I started work on a large low temperature Stirling engine, but abandoned the project and scrapped it because it was taking up space and I lost interest.  I wanted to use it as a teaching tool in Thermodynamics, but now I don't teach anymore.

Basically, to get usable power from a low temperature difference would take a lot of heat transfer (so I used small radiators) and volume.

Solar energy / Solar as alternate energy

Since I practically have no wind anymore, my only option for alternate energy is solar or heat differentials.
But solar is not much fun. Wind turbines are fun to build and test. Try building your own solar collector. You just purchase most of the components then plug it all in.
The other option, heat engines, could be fun.
I would like to make a large, LTD heat engine and use the temperature differential between my cold pond and a solar collector. Big project.
