How to Build a Solar Bottle Bulb 2.0 ( Updated English Version)

Mute sound (video has loud, distracting music) but good information:

1) Always scratch the sides of the bottle to create better grip to the sealant. The top part where the bottle meets the metal is the leak point in the build so use industrial strength sealant (epoxy or DOW Corning 791) on the top and bottom if possible.

2) Always put a protective cover over the bottle cap as the suns rays tend to make the original bottle cap brittle and a crack in the bottle cap will allow the water in the bottle to leak during evaporation.

3) Always RIVET the metal sheet holder on to the roof.

4) DON't USE THIN METAL ROOFING SHEETS. there will be no bite on the plastic bottle and the different expansion rates will cause leaks later on. Go for thicker roof sheet.

  • @CommentsSurvey vulcaseal is really sticky and is rubbery. when exposed to the sun it becomes hard like a rock. caulk or silicone sealant is good for preventing leaks but a stronger adhesive is recommended so the bottle wont slide off the flange.
  • @CommentsSurvey its a pvc endcap. any endcap fitting for pipes will do.

Email rec'd from Trang Nguyễn to me:

wow it does really workkkkkkkkk

it's easy to make all stuffs following the instructions.

we dont be allowed to make a hole on the roof , so that we pitch a tent and cover it by kind of black cotton (to stop a light, so that inside much more darker). Then follow steps. It works, thkz god.

I think it have no trouble for you to do it. Let do yours and tell me the great news then:x
