The 3 powerful intake fans are on the same level as my 48 wide 65 inch long mattress. There is 4 inches space or so at head and foot.
I push the mattress away from the fans to opposite wall, and hook the elastic bottom fitted sheet over the corners of two of the fans, and turn them up as much as needed to levitate the bedding.
If I do one layer at a time, which is best, then laying the top sheep and upto 3 additional blankets is done one at a time, and each layer likely requires a bit more fan speed.
If the bed is already made and I just hook bottom sheet over fan corners, I likely have to grab the center of the blanket/sheet mass and lift it, at which point it balloons up and levitates on its own.
There is that 8 inch gap from fan to mattress. The air would love to escape to these sides, so I stuff pillows on either side to block it.
Once it smells like laundry detergent, I unhook the bottom fitted sheet, and the balloon collapses. I then position pillows so their opening faces fans. They too balloon up. After a while I flip the pillows over to air out the other side of th epillowcases and pillow itself.
the down pillows have their covers go from loose fitting to taught, as the pillow itself expands completely.
Fiona's bed which is on my bed but up against back windows, I prefer to take outside put into direct sunlight, and shake it out and put the leaf blower on and through it, buty I can unzip it and inflate it as well, and it does get a lot larger and fluffier, like the down pillows.
When I have the bedding levitating and the edges sealed well, and the fans on high. I can throw a filled pint bottle of water onto the middle of the balloon and it barely makes a dent and rolls off.
But this is also 200 watts worth of fans, and I only have 198 watts of solar.
So I prefer to only use as much fan as required, and hooking the blankets to bungees crossing teh window above fans makes it much easier to levitate all of the bedding for as few as 30 watts consumption.
But for a time saving perspective I just crank the fvckers up and let em rip and in about 5 minutes it the interior smells like laundry detergent, at which point, I can turn the fans way down and just inflate the pillows instead.
Two of my blankets are Mexican blankets. They really shed a lot of fibers, and seem to collect the most unpleasant scent. The third is a zippered coleman sleeping bag, which itself can balloon up to 6 inches of thickness between the stitching. Making the bed atop the levitating sheets, one blanket at a time, the heaviest Mexican blanket seems to smell the most stale, even when it was recently washed, and spent the night rolled up under Fiona's bed.
it depends on overnight temps as to which blanket is uppermost. When hot, extra blankets are rolled up and the mattress pulled away from back windows 4 to 8 inches, blanket roll stuffed in gap,and Fiona's bed bridges that gap.
She loves to stick her nose out the pop out back window. Sheepdog sentry instincts, at least until sleep takes over.
yesterday when test fitting modified fan shroud and window frame, I also reattached fans and let em rip as I had not done so for far too long. It really makes it much more pleasant to climb into bed that night. not quite as nice as freshly washed sheets and bedding, but a dozen times better than without the levitation.
