I wan to thank you and this company for the support and advice given to me throughout the past months. My project was a success and i got a very high mark from my supervisor. The final designed and fabricated device was able to successfully trap and convert the exhaust gas waste heat into electricity well and with expected efficiencies. Also the water cooling block performed way better than the ebay Liquid sink i purchased. I was able to get 30% more power using your liquid sink than the ebay sink. i took it apart to see why it works so much better and realize just how much of a better design it is to the cheap one i tested against. It maintaining a constant cold side temperature though out the long test.

Thanks once again for all the answered questions and advice.

This last week i had more of a chance to play with the unit… and i am very impressed on its power output and ease of use, I’m using sterno for the moment to play with it, but will be trying a rocket stove for a more permanent setup.

I have shown the unit to a few peoples, so I understand about word of mouth, I am always “talking shop” about off the grid living… so I most certainly have brought up this device. I myself may order another one soon… Ive always referred people to there website when i get fun items as such…. so you’ve got my referral.

I received my IPowerTower, and I love it. I am just an individual, that experiments with off the grid power.

I have a cabin that’s powered with solar panels and deep cycle batteries… in the winter i have trouble keeping them charged so i purchased the Ipowertower to see if i could trickle charge my batteries and keep them topped off. For the most part my off the grid power setup is for lights, radio, media, charging laptops, phones, pads, Power tool batteries…. i know serious setups power entire homes but i don’t have washer-n-dryers, fridgerators, or any deep draw items, when i do need serious power i fire up a generator.

My draw to Seebeck devices is because here in Alaska or in any survival situation A Fire is a given… your gonna use fire than why not tap the power off it? and So I have played with individual Seebeck units and after tinkering and researching I came across your device and thought… Lets try it. Its affordable and is well designed. I went ahead and ordered your usb converter device as to not have to come up with a circuit for some of my experiments.

I can see a market for this here… we have lots of alternative lifestyle people here that do live off the grid. Your larger unit that attaches to a wood stove I think you call it the rabbit ears cool name sounds and looks Amazing! perhaps somewhere down the road I would like to try it out. But I have no business to sell items as such. I do thank you for the device, it arrived fast!

Thank you.
