Just responding to the 1st 3 response where it is thought to be a good idea to unhook the dryer vent and pump it into the house. ONLY DO THIS IF YOU HAVE AND ELECTRIC DRYER. Gas dryers utilize this air path to also discharge the carbon monoxide. You don’t want that pumping into your house.

For the electric dryer users, a good filter to trap the line is a pair of lady’s stockings that are no longer needed.

And we can run those pumps using geothermal energy from underground and using the force of the escaping methane in the tundra.

Just joking, no offense please.

Why Not Make a pipeline from Antarctica to cities across the world and pump cold air during the summer?

Or from hot deserts to cold cities?

If humanity has been able to combine a printer, fax, copier, and scanner into one device, I think the ingenuity exists to combine a refrigerator and water heater, or a large commercial refrigeration unit with an office heating unit.

Society has basically been enjoying a free ride on the multi-million year accumulation of oil and gas. These are starting to become harder to extract (why else is the price going up – do not be misled), and we will need to start think more carefully about each use of energy on a commercial and home level.

[...] The Sietch Blog brings to my attention the Freeaire refrigeration system, which seems to be designed for commercial application – but which makes such good sense! Essentially, it draws cold air from the outside into the fridge when outside temperatures are below freezing. Portland only has a few such days a year, so it wouldn’t be applicable, but surely a great idea for someone out there! [...]

My companies been selling such a system in the industrial spectrum for years, called Air Handling Units, they’ve been on industrial and commercial rooftops for years(20+). I write the control software and basically we look at outside air and demand air temps, then modulate vents to maintain a mixture. You just have to watch you don’t blow the walls out by overpressuring a room. Problem is, some places don’t want the outside air because it needs filtered/purified for food and bev apps.

I wonder how this will catch on without some kind of hygenic filtration process?

Great article,

This is the kind of simple idea that will work, because it doesn’t need rocket science and everybody can understand it. We really need more of that.
@mike : great idea to combine those two devices.

In fact we would need to completely rethink the whole thermal usage in a home, it isn’t worth producing heat in one piece to use a refrigerator or Air Conditionning in the next room, you pay twice.
Those devices in a chain should be fitted with (new) standard plug between them, in order to be able to buy or replace just a part of it.
I note these ideas for later.

>>>Isn’t outside air often too wet

Not in the winter it isn’t wet. At least not the winters where i’m from. Which reminds me maybe these refrigerators should run off that naturally occurring static electricity we get in the winter months.

Why not adapt this to datacenters that are in the Northeast and Midwest?

Isn’t outside air often too wet – you could end up with a defrosting problem on a scale you’ve never seen before.

I once saw a proposal years ago for a device that takes the heat from the refrigerator coil when it is in use and uses it to heat water.

now we need someone to build an appliance that is both a water heater and a refrigerator.

Dennis: check out the freeaire site (its ugly i know but full of useful info if you can slog through it all). They talk extensively about insulation on one of the many many pages linked on the home page. The duct work is highly insulated even to the point of them selling a giant 2 inch think rubber plug you can use to cap off the whole works (among other methods of insulation).
