Next I plan to modify the box so I can let the filtered warm air into

Hi Jimmie,

I know that it is tempting, but there are significant health
risks. You would be loading the air with particles that
cannot be seen, but do lodge in your lungs.

There might be ways (heat exchangers) to capture the energy,
but breathing the warm vent air is not the way to go.

All the best,

If you email... Please remove the "SPAMLESS."

Thats why I havent done it yet? I havent figured an easy way to filter
the air. I know of lots of ways to do it but not without a serious
constuction project.
