I got excited by this just now: A more efficient tumble drier - using a vacuum pump?
Couldn't resist a reply and plug:
Interesting. No reason why it shouldn�t work, though I�d imagine you need a mechanism to repeat the process over and over to vent the damp air and provide a fresh dry zone to migrate to, which would require the drum with the clothes to be connected through the spindle to a fairly robust valve/seal arrangement. But certainly the bearing could possibly be reduced, and the power of the motor, if one accepted a level of user participation load and seal.
There�s also some safety issues, but our pressure cooker already scares the willies out of me, so an implosion seems a better risk!
Would the elf and safety guys go for it? Or consumers if it�s a hassle. I�d don�t see the clothes suffering, especially if you pop them in with a dryer ball.
When it�s done, let me know. Of course, it's all still got an eco-cost.
Our dryer died not so long ago and we sealed up the hole in the wall:

and the metal panels are now doing good service as trays and the door as a salad bowl:

The non- urgent we hang all week in the conservatory and the urgents dry overnight (and still get fluffy in the void in the cupboard over the immersion heater, despite it now being very well lagged with that bonded blue stuff. We donated the old red lagging locally via JunkkYard:
