RE: [papercreters] Wind -was- Effective R-Value calcs

Thanks for the links.

I agree that wind is the way to go in the Arctic.  Homer is a lot different.  The key to calculating solar advantage is often figured on the loss from windows when not in direct sunlight.  This negates the advantage that can be gained if adequate insulated shutters are used when the sun isn’t available.  The poorly insulated house I’m living in is warming quite nicely by the low winter sun shining through my windows today.  The design we’re putting together for the forthcoming egg will have shutters that are cut from the shell to minimize heat loss in off hours.

 

Our winds are fairly regular but seldom sufficient to drive high tech wind driven generators.  My solution to this will be a large bladed mechanism with sails for low RPM high torque power in light winds.  Sails can be adjusted or feathered in high winds to prevent damage.

Battery banks will be made with FC and electrodes recast from recycled lead acid batteries, and browns gas from charging will be used to heat water, cooking, etc.

 

Summer Sun is continuous.

Solar power isn't practical in the arctics. Windows are just thermal
holes in the building. All loss and no gain.

However... Wind may be a real alternative. A 15-25 ft diamater wind
generator can accomplish a lot, and I suspect the wind in Alaska is
formidable.

Look for Hugh Piggot's book. It is far and away the best one out
there on the subject.

This site is a great one for people that want to build their own:

Keep in mind that the tower and the batteries each can be bigger
investments that a home built wind generator. Maintaining one is not
trivial, but there is no questioning the "awesome factor."
