Any idea how they 'stack up' [doh!] compared to a simular wattage powered 'finned' centrifugal pump?. Is there an advantage to Tesla pumps?(can you stack as many 'discs' as you like?), for some reason I'm guessing that 'finned' impellors will give more torque/head/pressure than a tesla, but a tesla might run faster with a 'light load' scenario. What do you think?, or KNOW!?
