Satellites have managed to detect faint electromagnetic signals generated by ocean tides, suggesting that space-born sensors ...

Researchers at the Chung-Ang University in Korea have developed a fire sensor that is powered by hydrovoltaics (HV) instead of batteries. Hydrovoltaics, where electricity is generated due to the ...

Other materials can also conduct electricity, as long as they let the charge flow freely through them. Like the graphite in a pencil. Or this salty water. Now, the outside of electric wires are ...

If you can’t answer the riddle, don’t feel bad. Metal conductors usually conduct electricity and heat. Usually, that’s true, but researchers at the Department of Energy’s Lawrence Berkeley ...

Safety is another concern. Salt water conducts electricity better than fresh water, which increases the risk of electrical hazards during firefighting operations. These risks and logistical and ...
