Personally, I disagree with the logic used by those above. If the bubbles are up, there will be larger surface area to absorb the sun's heat. Increased levels of heat absorption seems more important than the rate of heat transfer, especially when considering the fact that heat transfer takes place almost instantaniously.****i have tried it both ways, bubbles up or down. makes little or no difference heating. with bubbles down, though, it is easier to clean debrie off the cover and keep it clean.
When I purchased my solar cover I was told to have the bubbles down. This is logical since the bubble side is gray in color and the flat side is blue.
Yes, and you want the bubbles that collected the heat to be in the water to add to the temp.

The bubbles on the cover should be facing the water.
The bubble side always goes down.
I always place the bubbles down.
Bubbles down. Smooth side up.
The bubbles go face down on the solar cover because when the sun hits the smooth side if the cover it warms the bubbles up on the other side & the bubbles on the solar cover holds more heat than the smooth side
All Solar Pool Covers are placed on your swimming pool with the bubble side down, or facing the water. This allows an air pocket to form under the cover to trap heat & provide the maximum insulation value the cover is designed for. -Charlie Goss President DPD Pools / PoolDeals.com
Use a bubble type solar blanket or cover.
Sun Rings are safer, most are capable of generating more heat that a solar cover. The effect is that Solar Sun Rings with 70% to 80% coverage outperform bubble pack covers with 100% coverage. cheers mark tahiliani (jm)
They are the same thing basically. Pool Cover, Solar Cover, solar Blanket are all used interchangeably. It's basically some material, usually a plastic bubble mesh or vinyl covering that goes over the pool. The exception to this is Winter Cover which generally is heavier and designed to protect your pool during long winter months.
The didstributor says bubble side down ( for instance solarcovers.com). I do mine bubble side up because when I reel it in the bottom part is in contact with the pool edge and the friction may damage the bubbles.
you make sure the bubble side is facing down on the water.smooth facing uo toward the sky.

Yes. You want clear plastic for a solar still, because you want the sunlight to heat the wet material inside, not the black plastic cover.
a heliosphere is a bubble around the solar system blown by the the solar wind.
The pic associated with this answer has nothing to do with a Solar Cover or Solar Blanket. It looks as if these are solar panels for electricity. Solar blankets look like a stronger version of bubble wrap. Their primary purpose when they are laid on the water (bubble side down) is to keep whatever warmth the pool water has in it from escaping into the cooler air at night. They are usually a light blue or clear in color. Clear allows more sunlight into the pool to heat the water better.
My research online suggests that the 'bubble wrap' technology is standard for solar pool covers since the bubbles form the trapped heat layer. Regular pool covers do come in other styles, including mesh, vinyl or plastic as well as manual or motorized.
