    bot


    This simple DIY project shows how you can boil water with the help of a Homemade Solar Evacuated Vacuum Tube which can be made from any bottle and a $2 vase from Walmart.The vacuum is outside the bottle and offers great efficiency preventing heat loss. The water still boils at 212, it just has an insulator that allows sunlight to enter through the outer shell and absorb to the inner container. This allows heat to build without being leached into the outer environment.The other video shows  a Heating test with 2 Bottles ,one with vaccum in it and the other without.
