In the example in the article, they are using wind generated electricity to make the fuel. So, the process is...
Electricity -> Synthetic Diesel Fuel -> Combustion -> Power (to wheels of car)
While for an electric car...
Electricity -> Battery Charge -> Battery Discharge -> Electric Motor -> Power (to wheels of car)
So, for the Electricity ->
I am not trying to say that there won't be a place for this technology. I just think that in most circumstances electric cars will be a much better option.
** A normally fueled car usually has a well-to-wheels efficiency of around 14%, so as far as actual energy efficiency goes, this fuel is doing pretty well. It just looks bad next to the high efficiency of electric cars.
Diesel Fuel + Oxygen -> CO2 + H2O + Energy
So, I would assume the opposite would be...
CO2 + H2O + Energy -> Diesel Fuel + Oxygen
The reason why diesel engines have problems with NOx emissions is because the high temperatures and pressures in diesel fuel cause the nitrogen in the air to react with oxygen. Nitrogen is not normally a component in diesel fuel.
Along the same lines, cars burning this fuel would probably still have NOx emissions.
The $20 part is so you can pay $900 for the $600 phone over the two years.
$20 * 12 months * 2 years = $480
Am I missing something?
