Eco-footprint – Measures how much land and water area a human requires to produce the resources he consumes and to absorb his wastes. It compares human demand with planet Earth’s ecological capacity to regenerate. Estimating how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. Example: For 2005, humanity’s total ecological footprint was estimated at 1.3 planet Earths – in other words, humanity uses ecological services 1.3 times as fast as Earth can renew them.

In 1800, Alessandro Volta made the first battery by layering plates of silver and zinc with blotting paper that had been soaked in salt water, he called it a voltaic pile. Each layer in the pile increased the battery’s voltage. In 1859, a French physicist named Gaston Plante created the lead acid cell. It later became the world’s first rechargeable battery.

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and in reverse, from the cathode to the anode, when charging. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the devices they power. They’re generally much lighter than other types of rechargeable batteries of the same size. (more…)
