|
| |

I would like to arrive on a random winter morning and find the inside temperature at or above 10deg C. Additional heat would come from a wood stove. The problem is how to get enough thermal mass !... more »

The "beauty" of wind turbines (as will be recognised by future generations)
|
| |
We love windmills and there's no denying it - they definitely have a certain appeal. They creaked noisily around in their charmingly inefficient way and did an amazing thing. They harnessed the power of the wind to facilitate activities like the baking of bread. Modern wind turbines are beautiful things. Within their graceful... more »

Is 0.03 gpm per square foot a good number to shoot for on a MTD collector? Is 2-3 gallons of storage per square foot a good number to shoot for on a MTD collector? Any suggestions on a source of large sheets of mylar?

Oil! Will discovery dampen solar energy uptake?
|
| |
With the recent news regarding BP's new oil find, do you feel this sort of headline gives consumers a 'false' hope that oil and other traditional fossil fuels won't run out and that there's no need to explore alternative energy generation?

Aluminium/Copper Corrosion, does it stop?
|
| |
I made a solar panel with copper tube risers and aluminium heat collecting fins. The fins were formed with a semi circular slot (the same diameter as the riser) running down the middle. and two of these fins were clamped around each riser using pop rivets. The panel works very well, but a white powder corrosion has formed... more »
