Natural gas car not useful

Basic decision against gas cars. Why this dispensable step in direction of a future mobility is not necessary.



  Gas is also fossile energy


At the Citroen C3 is the difference between gasoline and natural gas 154 g CO2/km and 119g CO2/km. The bigger C4 emits as a hybrid only 90g CO2/km and even this can be radically reduced changing the monovalent Dieselhybrid to a bivalend Hybrid where it's possible to drive the first kms by electric power, falling down from the sky.

Why all this effort to reduce the CO2 emission from the small C3 from 154 to 119g/km, when the bigger C4 shines with 90g/km. It's only 35g less CO2. Instead of a costly gas refuel station in the garage, spent a electric charger for the C4. When a C4 drives 39% of his ways by electric power produced withoug CO2, this would be also 35g less CO2. Down from 90g to 55g.

  Rational use of biogas


More than 60% efficiency at electricity from biogas is state of the art. But what is the efficiency of a gas engine in a car? Not the best efficiency, but the average efficiency in city traffic, because the gas is not for long distances, the C3 drives on long distances with gasoline.

It could be a 1:4 difference between biogas in a high temperature fuel cell with steam turbine to make electric power also from the waste heat and a high efficient electric car and a gas car with Otto engine.

Out of this reason, use resources usefull, make out of gas or biogas electric power in a high efficient fuel cell and recharge a bivalent hybrid car instead of wasting it in very inefficient cars with Otto engine in city traffic.

Hybrid cars
Why arrived the hybrid car not earlier. What problems solves the hybrid car? Can the hybrid succeed against cars with hydrogen and fuel cells?




  2006 the dusk for fossile fuel starts


Cheap mineral oil was yesterday, the price system between differen energy sources and technologies for usage in the area of mobility changes durable.

Price development at fuel
Energy becomes more expensive wail the fossiles. Wrong, only the short dated special deal fossile fuels becomes more expensive. Long time available energy becomes cheaper.


Electricity comes out of the plug
From where should the electric power for electric mobility come? Some people belive the electric power comes out of the plug. Other belive electric power falls down from the sky.


EVER Monaco vs Hannover hall 13
2 exhibitions with the same theme, our mobility in the futures, but contrariness to the thematic similarity, differences like day and night.


Hydrogen age
Physics can not be changed. The physical physical of hydrogen are known. The hydrogen age is q question of believe.


Hybrid vs hydrogen
The duell over the future of mobility. In one corner the since decades proclaimed hydrogen, on the other side of the ring: Hybrid with Lithium based batteries.
