Thermoelectric Power Generation (TEG)
31 Minutes of Thermoelectric video heaven!
Here we are going to build the single TEG generator shown in the first video.
Use the engineering drawing to produce internal coolant passage ways in the aluminium block. I ended up drilling all the way through to the other side and using more of the 1/4″ blanks.
Connect the 1/4″ pipe fittings to the block and plumb in the pump. Add antifreeze to the water in the water butt if it’s likely to get cold at all.
To create a ‘sandwich’ with the hot block (steel block), the TEG and the cooling block, drill and tap holes in the steel block for the 5mm bolts.
Weld the hot block into the side of the wood burner and recreate the TEG sandwich, tightening the bolts up with a torque wrench (see attached file).
Connect up LEDs on the TEG, turn on the pump, light the wood burner and off you go!
If you really must build the 10 TEG generator, the photo above shows what is involved. I have got CAD drawings, PCB drawings etc. If anybody is interested. Not for the faint hearted!
