Because a TEC (Peltier) is really energy inefficient when it comes to the amount of power consumed in moving heat. The average person produces anywhere from 100 to 120 watts of heat at rest. So, say with the surface area of just the torso, 60+ watt of heat needs to be removed. The TEC will burn through battery life in a hurry, unless you can connect it to an accessory power outlet. Though depending on the motorcycle you might be able to have enough amperage on a 12v outlet to suffice.

 

The low tech method is just using water to provide evaporative cooling. The problem is that it doesn't really work well or at all in humid southern climates.

 

The best approach would be to drive an internal pump that moves fluid around a coiled loop. It can pass through an aluminum heat-sink (metal plate) on the sides so the wind could dissipate the heat. Would use a lot less power to the point of being battery operated.

Sony be like : Suggested retail price at 13,000 yen !
Amazon be like : Make it double at 23,600 yen instead.

 

According to the price history (Keepa), the initial cost was 14,300 yen for the first 18 hours of the day on July 1st. But then they suddenly decided to price gauge everyone, increasing the price to 38,800 yen at 19h00, until it fell back down to what we currently see.

 

I might be interested in this, if and when it ever comes to Canada.

It's not uncommon, if stock was really low, that pricing shot up really high. Happens with virtually every product on Amazon, unless it's something that the seller is trying to clear out, in which case they go super low.

 

Haha, why would this come to Canada? For the 2 months a year when it'd actually be useful?

It's a 500Yen shirt with some extra sewing for 1800Yen. 

 

It's being targeted at people with enough money for a portable cooling unit who have heat issues. 

If anyone sweats enough, you could go through 5-10 of these shirts a year. It's a built in subscription service. 

164.01CAD as per Google if you're getting it at MSRP. I'm aware the Amazon price is a bit higher. 

The point is kind of that you don't sweat...so...

Probably a better comparison is it’s delta rather than a subjective figure (23 has me sweating while 13-16 is ideal)

I feel like the main use case for this is people that work outside. Little different then sony's normal.

It's probably the flip of the "hot hands" type of chemical heaters people stuff in their pockets in the winter so they don't get too cold. So here it's probably the equivalent of a small ice pack.

 

It does not really have much practical use however. Anywhere you could use this would likely already be dangerous to work in. It might give people working in a field or stupidly mowing their lawn in the middle of a sunny day a way to work it, but for all intents, if you need this to do work outside, then the work should be giving you hazard pay.
