The only way I see it being practical is to design some
sort of heat exchanger to use the outgoing hot, humid
air to heat the incoming cool, dry air.

I agree

And Im surprised something like this doesn't exist that
one can buy!

Maybe its our million dollar idea? Yes?

Not really . . . I put a king-size pillowcase on the end of the dryer hose
and held it on with rubber bands. Filtered out the dust, added much needed
humidity to the dry winter air. Every so often, turn the pillowcase
inside out, throw away the dust, and run through the laundry, and it's ready
to go again . . .
More like a $2 idea . . .

I really wasn't going to post on this thread because it seemed just
darned silly to me. I'm single and the amount of time I run the dryer
is minimal. This topic may be important for large families doing
laundry every day, but it isn't very important to me. That said, ....

I may be wrong, but I believe the big energy waste with dryers isn't
that you're losing all that heat from the dryer to the outside, it's
that you're pumping inside air, heated inside air, into the dryer to
dry the clothes, then pumping that air outside. And any air you pump
out of the house will be replaced by outside air, and if you live in a
cold climate, that outside air must be heated to inside temperature.
That's the big waste of energy. So when you kept the air inside, you
of course humidified the air, but you also stopped that loss of inside
air. Congratulations, you solved a problem you didn't even know
existed.
