Electric Clothing

Here is another post showing that we are not merely helpless victims of resource depletion, but rather that the new situation offers challenges that actually can be addressed. Take indoor heating. During the middle ages people had open hearths, causing you to be fried on the front side, while you still frooze on the backside. Central heating improved things dramatically. But that invention seems to be heading for the exits together with fossil fuels. How can society react? We could take some clues from motorbike drivers. During the winter they sometimes wear clothings with special heating wires and thus keep comfortable warm at minus 20 centigrade and speeds of 80 miles/hour. This reminds us that there is no need to heat walls, furniture, books, large bodies of air etc. We only need to heat the few milimeters of air between the skin and the cloths. The motorbike cloths shown in the video typically consume 90 Watt. But this is for outdoors while driving with high speed during the winter cold. Electrical blankets operate at ca. 60 Watt. ‘Electric clothes’ can operate more efficiently. In Holland on an average winterday outside temperatures are a few degrees Celcius above zero. Dutch homes typically have large windows, usually with double glass, resulting in a room temperature of some 10-12 degrees Celcius without additional heating, solely from daylight radiation and body heat from the inhabitants (let’s face it, ‘human’ is just a nice word for an in essence exogene chemical process to the tune of 100 Watt). That means that one only needs a fraction of these 90 motorbike Watts mentioned earlier to keep warm indoors. Maybe 30 Watt? We think this could be a golden business idea to produce a combination of bureau chair covers, with seat and back functioning as electrodes, to avoid the need to plug yourself and casual thermo-wired clothing, to be used for instance by office workers. This way the employer can save on the energy bill and the employees stay warm. It could also be useful for people at home with a small purse. 30 Watt times 16 daytime hours = 0.5 kwh. That’s ca.10 dollar/euro-cent per day. Meaning you can reduce your energy bill for heating to 3$ per month. A single person household easily has to pay 100 euro per month on heating alone.

In northern Europe 5 MW wind turbines are now increasingly being installed and soon will be the norm. One such machine (operating in full capacity) can keep a mid sized city of 100,000 warm in the way described (50 Watt per person). One such machine costs 5 million euro or 50 euro per person one time investment. It probably costs more to buy the special cloths with thermal wire (12 volt).

Who wants to become a millionair with this business idea? We internet junkies at DeepResource are too lazy to run a sweat shop. We trust you to send us 10% of your profits for the idea.

Update: to undermine what is written above we discovered that out idea was already implemented without the proposed conducting chair covers, but instead using batteries that can last for several hours. [Source] We are tempted to give it a try and will report on our experiences when they occur.
