Now forgetting about stirling... So you clearly thing that with today's technology, using a turbine is a realistic solution for a serial hybrid vehicle ?
what is the minimum realistic power of a turbine, at 400C, at 600C ? is 10-15kW mechanic reasonable? which effciency ? is 50kW mechanic reasonable... which efficiency ? will organic rankine turbine have any interest à 400C ? 600C? for cooling faster? note that about the problem I see two tracks for hope : - when the car goes fast, it consume much heat, but air flow can be used to cool quickly... if going slower, need less power... could even use a fan... - second if thermal evacuation is a problem, maybe on could design the car to be a good radiator does it seems reasonable ? 2012/2/6 Robert Lynn <[email protected]> > So take an (optimistic) $10k 30kW 200kg Stirling + generator + very large > radiators (need much cooler temps than IC engines) to the already heavy and > expensive $5-10k electric powertrain and you can perhaps begin to see why > stirling is such a non-starter for vehicles compared to: > Rankine turbine generator + condenser that weighs perhaps 100kg (turbine > and generator are smaller as operate at much higher speeds) and costs > probably $3-5k when mass produced. > Recuperated Brayton (like capstone C30) that weighs 100kg and costs about > $5-10k when mass produced. > > >
