The Hybrid Car creates a big demand

...............in Batteries.

The use of intensive electricity store (Watts/kg) batteries raised the demand of various materials. This will have impact on such materials.

cheerios!

Battery development now is getting strategic

.................in conjunction with the higher W.H/KG needs of industry.

The Biggest Battery companies now are in Japan, Hong Kong where the electronic industry is very strong!
At the moment, the capability of batteries are rather primitive

= Ni-Cd system has 50 - 150 W.H/kg
= Li-ion system has 250 - 300 W.H/kg
= Ni-Metal Hydride has 300 W.H/kg

With bigger power needs of the automobile hybrid technology - automotive research and development outfits such as Daimler, Toyota, GM, Ford, Honda, Peuquot, Citroen, BMW, VW, Fiat-Chrysler will be joining the electronic industry for search for better  W.H/kg ratios.

Nickel, and the secret hydrogen absorbing "alloy" - said to contain rare earths will BOOM!

Cheerios!

Imagine a MBT with such fuel cells....almost silent upon the battlefield....awesome tactical advantage to have! Of course, significantly lighter, but impervious armour would have to be developed to maintain an adequate power to weight ration, if not even lighten the load to make the MBT even faster.

Battery technology or FUEL CELL technology needs to be improved.

YES, that'll make 7th generation military!
If you can only store 300W.h/kg - imagine how "UNDERPOWERD", your "electric" MBT would be.
Currently MBT runs on much higher power - M1A2 Abrams is 62 tonnes, with 1,120 KW engine with 2T of fuel.
That works out to be 18 KW per T - with range of 500km.

Cars are even more POWER PACKED, with 120kW for 1.5 tonnes.
The motorvehicle only needs to store 60kg of fuel to gain 500km of milleage.
It's still a long time away for that to work!

Uranium is outdated - we have something much better: Thorium reactors. Our planet provides us with ample amount of the heavy metal, it's not as rare as uranium. And as thorium reactors can't become over-critical, even breeders, an uncontrolled fission is not possible, which is why well designed thorium reactors don't pose any threat at all to the environment or to people living around them.

China also joined the club of countries developing those reactors, so perhaps the first commercial one will even be built in asia.

The problem with nuclear is SIZE!

Ask yourself (1) What's the KW.H/kg of material.
                   (2) The size of equipment needed to tap the energy.
                   (3) Can the technology fit the frame of 1.0T to 60T vehicle needing the power.

Then we are really talking!

Cheerios!
