Matrix’s PowerWatch 2 needs no charger, uses body heat and solar power

So basically it's a useless piece of shit, which may or may not charge its own battery.
Thanks for clearing that up.
Oh, so you're suddenly believing the words of an online reviewer who has adverts on his site? What happened to all those 'paid shills'?

:facepalm:

I'm believing someone who, quite obviously, isn't a paid shill. He's saying it's a useless piece of shit. Do you have anything else to add that contradicts HIM?
 
Fuck me this was hard work. Trying to convince someone that a useless piece of shit is nothing more than a useless piece of shit!
 
No I didn't! You made that up! I said, and I quote
"People who get free tech and make money from reviewing it are by default paid shills"
It isn't my fault that you can't understand that!
But the reviewer was GIVEN FREE TECH and made money from reviewing it. That's exactly your criteria for a "paid shill."

:facepalm: :facepalm: :facepalm:
 
So, editor, are you submitting, and accepting that this amazing piece of kit you posted is nothing more than a fairly useless piece of shit?
My opinion has been consistent from the start: it's interesting tech but v1 was flawed and v2 looks more interesting - an opinion echoed by the many reviews I have read.

That doesn't alter the fact that you lied about what I said.
Do you admit that you lied about what I said?
Do you admit it's a useless piece of shit, that's about as good as, and 100X more expensive than an ebay special watch from China?

Apart from the review you posted, that says it's a useless piece of shit?
 
Eh? You've just shot yourself in the foot and now you're trying to hobble on like nothing happened!

Is this guy a "paid shill" or not?

YES/NO?
Did I say he was? Please point out where I did that!
My mistake... Debating 101... never enter into a battle of wits against an unarmed man!

Gladly. You said:

This person got free tech and made money from reviewing it. Therefore, by your own definition, he is a paid shill.

BY DEFAULT! They don't have to adhere to shilling practices! :facepalm:
There, I dealt with your point. YOUR TURN!!!!
 
It isn't difficult. I say that with any useful features used or added, this watch can't charge itself. Do you disagree? If so, please post evidence to support YOUR claim!
 
Given that both the manufacturer, and a reviewer of editor's choice say that it's useless, I think that conceding that it's shit would be the right thing to do.

No one seems to say it’s useless, just that its uses are limited.

It’s certainly impressive given the charging technique, but as an application of it, I don’t think it’s there yet.

Impressive? :D How is it better than a 3 quid watch off ebay, whose battery will last 3 or 4 times longer?

And that's exactly what I've been saying all along. It's clear v1 was not the finished product and I suspect that v2 will be far from a super-polished watch, but it's clear that their charging tech has immense potential and I wish that was what we were walking about.

I think Saul’s initial position was from the perspective of this being a full-fledged smart watch, and he has dug himself in a bit.

Being fair, we have discovered more details as we go, and the functionality that kropotkin was talking about seems some way off, as does the idea of full GPS functionality.
 
Anyway back to talking about the watch.

PowerWatch2 has already raised $1.3m on Indiegogo

Their own techie blurb:

MATRIX Gemini Thermoelectric Generator
thermoelectric-gemini-teg-695.gif


Our thermoelectric technology converts heat to electric power, the same technology used by NASA to power the Voyager Spacecraft and the Mars Rover. It is based on the Seebeck effect discovered in 1821. In the absence of an applied voltage gradient V, electric current, J, can still be generated if there is a temperature gradient, T. A thermoelectric material must have a low thermal conductivity and high electrical conductivity to function efficiently. These properties are not commonly found in nature.

In order to make a thermoelectric material efficient, one must use a semiconductor whose Fermi level is tuned correctly by doping. Too much doping, and the Seebeck coefficient decreases. Too little doping and the electrical conductivity decreases. In addition, the semiconductor should have some mechanism to scatter phonons frequently. MATRIX has developed a nano-structured semiconductor, the Gemini, that accomplishes these things.



MATRIX Mercury

A thermoelectric module is composed of many tiny semiconductor "legs" that when added together create a larger voltage than one individual leg alone. However, the voltage generated by body heat is on the order of 20 to 100mV, too small to operate electronics. A DC-DC boost converter is needed to boost this small voltage to 5V to run the electronics and charge a battery. Current off-the-shelf boosters have terrible efficiency and large startup voltage. MATRIX has developed the world's most efficient booster with the lowest startup voltage on the market today. We call it the MATRIX Mercury.

Together the MATRIX Gemini and Mercury outperform any combination of thermoelectric and boost converter by 3X. To learn more, please visit www.matrixindustries.com
The finished v2 watch is scheduled for retail in June 2019

Scheduled for v2 apparently.

Interesting that it doesn’t talk about how they are venting heat. I expect they are playing their cards close with that.

The rest of it isn’t really saying much in terms of common knowledge.

The fact that they can support push notifications is the most interesting bit.
 
Fuck me, it's like talking to 3 year olds or 93 year olds. How can neither of you see that this can't work? Have you no idea what electricity is? :D
