There's absolutely nothing wrong with being skeptical, but the characterization is that we're a bunch of fly-by-night marketers. The team has between 5 and 13 years of thermoelectric experience. We're a bunch of geeks like you guys, PhDs in EE, Chemistry and Materials Science.
No one said otherwise. A cursory glance at your profiles reveals that.
That does not mean your product is practical though.
The Arrow certification was important to us to quiet the skeptics. They reviewed the entire circuit diagram. It was not just a bill of materials scan.
Err, the "circuit diagram" is nothing, the entire practicality of this concept relies
entirely upon the system engineering of the entire solution. Thermodymanicas, the power envelopes, and the
BTW, who are we actually speaking to here?
BLE radio obviously requires a lot of current, and that's where the internal battery takes over. Otherwise, your body heat is generating the power for the watch. That being said TEGs can light up LEDs when designed right.
Spare us the LED anecdote, please quantify your answers, we are engineers here, many with vast experience.
I'm obviously not going to change minds here and so I won't even try. My offer still stands that if any of you want to visit our lab and see a watch build from the bottom up or any of our other energy harvesting demos, you are welcome to. That's probably the only way for you to be convinced that this tech is for real.
Come on, don't give up, just so are the data, some data,
anything.
You can change our minds very easily.
Why won't you simply provide us with data?
Are you unable to, or afraid to?
I think it's a pretty reasonable request.
I went through some ballpark calculation before based on your own number, please tell me were I went wrong and why.
And please tell us why your TEG solution is in any way more practical than a simple USB charging solution.
I'll do an additional calculation to the ones above, maybe you can comment?
Let's say you use the bluetooth until you drain your battery (can you give us the data on that?), and then decide you want to charge up your watch again.
You would have to exercise for
1200 hours straight to do that based on your best case number of 500uW, assuming no losses.
How then is TEG a practical charging solution?
I feel a video coming on...
