About the PWS
The PWS
The PWS is an efficient and inexpensive way to imitate photosynthesis and obtain storable fuels. It is 20% more efficient than past technologies and produces more hydrogen, which is stored as fuel.
How It Works
Water is poured into a glass tube that is coated inside with semiconductor material. The tube, which runs along the focus of a parabolic trough, receives light rays from the sun reflected from the inside of the parabola itself. This catalyzes the splitting of water inside the tube while recycling the excess water and oxygen and saving the hydrogen for later use.
In natural photosynthesis, the water-splitting step produces oxygen gas and hydrogen ions, which are eventually used with carbon dioxide to produce sugars, or energy for the plant. In comparison, artificial photosynthesis systems, such as the PWS, would produce hydrogen and oxygen gases as the final products within the tube. The hydrogen gas would be kept separate from the oxygen, stored in tanks, and would be used to power everything from cars to power plants.
