Super conductivity is a natural phenomenon in which certain materials such as metals‚ alloys‚ and ceramics‚ can conduct electricity without resistance. These materials are what we call superconductors. In a superconductor‚ once the flow of electrons begins‚ it essentially goes on forever‚ making it an important material to humans. Superconductivity was discovered by a Dutch scientist by the name of Heike Kamerlingh Onnes in 1911. While researching properties of materials at absolute zero

Activated Carbon Filters Media [pic]"Activated" carbon filter media is produced by super-heating dried coconut husks in a low oxygen environment‚ using a process called pyrolysis. The resulting "biochar" husk‚ is a purified form of carbon‚ containinglarge amounts of cellular sized surface area‚ negatively charged to attract positively charged toxins. Toxins in the water become attached to the husk’s carbon surfaces.Over time‚ the attractive charge of carbon surfaces are neutralized‚ making it time
