I can imagin this hoseclamped around a regular ol pot and boiling water!

Maybe some heat sinks or water cooled on the cold side?

I have an EcoFan 1st gen.  Went to a hardware show for dealers and a cute gal asked me if I was familiar with them.  "Yes!  And they wouldn't blow a sick mosquito off course!"!  "Well, let me send you our new 2nd generation to try!"

 

It will blow a sick mosquito of course!  Maybe a healthy mosquito!  But is it a fan?  Maybe not...

 

I'd want something like that to charge a cell phone.  I have no mosquitos during heating season...

Dunno why you couldnt use a few modules and a computer fan lol

All they managed to do is to turn fan blades from the heat atop the stove.  Looks great!  Does nothing!

I'd like 5-10 watts from the unit.

I ever find some free time and a little extra cash, i may order some of those modules and see what i come up with

important to note he used the cooling modules rather than the last ones I pointed out. Id run those in pairs for 8v and 1.2a for each pair and run at least 2 pair for 8v 2.4a.(you would then be able to run that USB buck boost converter he used at lower temperature, and maybe not need ice etc.) So even if you only got 2.5 or 3volts you should have close to 2 amps available(about the equivalent of a plug in wall charger)

Model: SP1848-27145
20 degree temperature difference: open-circuit voltage 0.97V,generated current: 225MA
40 degree temperature difference: open circuit voltage 1.8V, generated current: 368MA
60 degree temperature difference: open circuit voltage 2.4V, generated current: 469MA
80 degree temperature difference: the open circuit voltage 3.6V, generated current: 558MA
100 degree temperature difference: open circuit voltage 4.8V, generated current: 669MA

 

I still think  boiling water would be an excellent way to do this. Maybe modules around flat sides of a square pot with outer cooling fins?

With wood gas aka producer gas your dealing with a low pressure system so high pressure hoses, water heated regulator are not needed to run a low pressure system.

 

John on the phone last night discussing our river water project when forklifts became part of our talk regarding LPG fuel, this is when I told him I was on the lookout for an Impco 425 mixer. Like me he's dealt with scrap metals most of his life and as it turns out he had been saving all the LPG and natural gas systems that came into the yard.

 

I now have the mixer I've been looking for soon to be sent parcel post.

 

 

 

The Impco mixer John is sending came off a GM 454 and has the quadrajet base adapter, should be an interesting project.

Interesting.  Glad he did it instead of me.  I tend to set the bar at charging a cell phone but just making a bit of light is intriguing!

Still wonder what other Peltiers might do...

Guess that would run most anything I have!
