Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

A very wise friend of mine told me  As you have often noted, these better battery papers appear weekly. Then we never hear of them again because of an engineering problem, or a toxic/expensive ingredient. [/i]Lets hope this story pans out as they started from the ground up and have come up with impressive results.[/color][/font]
Researchers at the University of Illinois at Chicago and at Argonne National Laboratory have designed a new lithium-air battery that works in a natural air environment and still functioned after a record-breaking 750 charge/discharge cycles. Their findings are reported in the journal Nature.[/color][/font]http://revolution-green.com/new-design-produces-true-lithium-air-battery/[/font][/size]

I really do not think people know just how low the energy density of even the latest high end batteries is.

To put things into perspective

Lithium Metal (Li-Po, Li-On, Li-Hv) has a specific energy of 1.8 MJ/kg

Timber= 16.2 MJ/kg  ;D

Sugar= 17 MJ/kg

Fat  (animal/vegetable)=37 MJ/kg

My cup of coffee (white with 2),has more stored energy than the $400.00 lithium ion battery in my Ebike

As i stated above--i really do not think people know just how poor our batteries of today are,in way of how much energy they can store.
