Re: encouraging environmentally-friendly lifestyle
but... but... but... arent hybrids more wasteful? consider the coversion from heat to electrical then to chemical and lastly mechanical, as opposed to heat directly to mechanical?
Where battery power is too weak for electric motor to effectively power car, the combustion engine kicks in to generate mvt directly from fuel combustion.
Heat is the unwanted by product in any combustion engine and 60- 80% of the actual energy in petrol fails to convert to kinetic energy in internal combustion engines due to friction/ other losses manifested as unwanted heat/ sound energy dissipated.
Each hybrid car thus has 2 power sources, a combustion engine and a battery driven electrical motor, used alternately as programmed.
i'm very ill-informed on hybrids fyi...
