whats new offered in the Bmw H2r

and you can see more number of Bmw wallpapers here.

Hydrogen is only the simplest grade school demonstration of chemically storing energy, not necessarily the best suited for vehicles. Indeed the low volumetric energy density of 405 KWh for compressed hydrogen (at commercial pressures of 150 bar, that's about 150 atmospheres) when compared to that of gasoline >9,000 KWh it's obvious that hydrogen cars would be short range commute vehicles unless cargo and passenger space is sacrificed for fuel.
