Dave, I’m not refusing, just giving it a lot of thought. You’re obviously a brilliant guy and I don’t want to get into a pissing match with you.
There need be no pissing match, simply post some data.
It’s hard to answer this question because how do I encapsulate the last five years of our lives, actually 13 years in my case, in a neat, tidied up answer to a complete stranger?
What's that got to do with anything?
You are taking people's money and selling a product. That product is either useful or it isn't. It's either practical or it's not.
Based on the numbers I don't see your product being either of those things, and you have provided no data or clarification otherwise, just this "we've been working so hard at it, it's our life and passion" speech.
You are not selling that story and asking for donations to fulfill your dreams, you are selling a product that is being marketed in a certain way that makes people think it's useful, when clearly the calculations show it's not.
The PowerWatch generates more power than it consumes when it’s worn.
I have absolutely no doubt that it does.
What you are not seeing here is that concept is
entirely pointless apart from being cool gimmick.
You could have put a CR2032 coin cell battery in there and gotten the same "never have to change the battery" claim. You can buy 10 year lifetime battery watches from Casio and others.
But what happens when it’s taken off and left off for a long time? What do you do when you have enough room to add a 200 mAh battery? Do you choose a tiny supercap instead that barely supports the BLE TX, RX, syncing?
Ok, let's look at the bluetooth syncing.
Give us the numbers on how much power is generated per day vs how much energy is required to bluetooth sync once a day.
Also we chose to come out of stealth with a commercial product, but in the big picture, we see this tech going into smart sensors for factories and industry, smart logistics, perhaps medical devices like hearing aids. Longer term, this technology, we hope, will help increase fuel efficiency for power plants or automobiles, which we hope would be good for the environment.
That's great, but has absolutely nothing to do with the practicality of the product you are taking people's money for.
I guess what I’m trying to say is that we’re very passionate about thermoelectrics. The most inspiring photo ever captured in my opinion is “The Pale Blue Dot”, when Voyager 1 turned around and took a picture of Earth. Carl Sagan has a beautiful description of it. Voyager 1 is of course powered by a thermoelectric.
Again, lovely rhetoric in place of data.
