Salt and Pepper Batteries!!
When we talk about renewable energy and all the modern science and technology involved in all these new heating systems, i never once thought that some every day products that you find in your kitchen could produce energy, hey but you do learn something new every day. Just found this interesting article on ''The Discovery Channel'' website.
A piece of wet, salty paper doesn't look impressive, but cut it up, stack it up, and it can hold an impressive amount of energy.
With this in mind, scientists in Sweden have created a salt and paper battery that can hold up to one volt of electricity.
The scientists hope their battery will one day power remote, biodegradable sensors.
"We wanted to make a battery that was very simple and used the same material for both electrodes," said Leif Nyholm, a professor at Uppsala University in Sweden and co-author of a study that appeared in the journal Nano Letters. "To make it simple we just put NaCl (table salt) in."
