Super-insulated clothing could eliminate need for indoor hea

Unread postby Keith_McClary » Sun 11 Jan 2015, 01:47:47

(Phys.org)—By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. Considering that 47% of global energy is spent on indoor heating, and 42% of that specifically for residential heating, such highly insulating clothing could potentially have huge cost savings.
...
As the researchers explain, most strategies to reduce indoor heating focus on improving the insulation of the buildings, such as by using high R-value insulation and low-emissivity windows. However, a large portion of the energy is still wasted on heating empty space and inanimate objects.
To avoid this waste, the researchers have used a new strategy called "personal thermal management," which focuses on heating people. They've demonstrated that clothing dipped in a solution of metallic nanowires, such as AgNWs, achieves this goal by both providing passive insulation and allowing for active heating when connected to an external power source.
The main advantage of the AgNW-coated clothing is that it reflects over 90% of an individual's body heat (i.e., infrared radiation) back to the individual. This reflectance is much higher than even the warmest wool sweater, as the average clothing material reflects back only about 20% of body heat.
...
Besides providing high levels of passive insulation, AgNW-coated clothing can also provide Joule heating if connected to an electricity source, such as a battery. The researchers demonstrated that as little as 0.9 V can safely raise clothing temperature to 38 °C, which is 1 °C higher than the human body temperature of 37 °C.

I guess waste products would be incinerated by the heated silver nanowires in the suit.

Oh, wait, ... , you meant the plumbing in the house.

Yet another way to kill the house plants. :-)
Imagine changing a babies diapers while trying to keep it warm with one of these suits.

This could also increase the need for deodorant!

It strikes me a as silly, around my home we dress warm and keep the thermostat turned down. Most people in the USA would rather dress in pajamas and turn the heat up to 75 or 80 Fahrenheit.

What does one do when it's time to shower or bathe?

And silver? Won't that make the clothing a bit pricey?

It's like a better thinsulate. It may have its uses. But I'm so getting tired of these new marketing buzzwords for basic concepts that have been around for ever. "Personal thermal management?" Please. Put on a sweater. Battery hunting socks. So it's higher tech but not that earthshattering but it does have nano in the name.

I posted this stupid thing somewhere else. "Personal hydration management"! Whee !

Yeah but it is a hard sell ...
