But it wasn't until the 17th century that attempts were made to harness the power exhibited by Heron's aeolipile for practical purposes. In the first century A.D., Hero of Alexandria invented the aeolipile, or primitive steam turbine. Credit: Public domain.
Borax is a good natural choice for cleaning mold. It is toxic if you swallow it, but otherwise, it does not emit dangerous fumes or chemicals when you use it. What makes it great to use on mold is that it disinfects the surfaces it cleans. You mix borax with water in a one cup to one gallon ratio.
Borax has many uses on its own, plus it is an ingredient in other products. Here are some uses of borax powder and pure borax in water: 1  insect killer, particularly in roach killing products and as moth-preventative (10% solution on wool). 2  fungicide. 3  herbicide.
