..depends on your biomass and on your sterling Stirling's efficiency,
divide your output by your efficiency to get your input, e.g.:
arnt at celsius:~/FG-git$ qalc 100hp/25% to kW
(100 * horsepower) / (25 * procent) = approx. 298.27999 kW
arnt at celsius:~/FG-git$ qalc 100hp/25% to MJ/s
(100 * horsepower) / (25 * procent) = approx. 0.29827999(MJ / s)
arnt at celsius:~/FG-git$ qalc 100hp/25% to kWh/s
(100 * horsepower) / (25 * procent) = approx. 0.082855554((kW*h) / s)

..burn wood?
arnt at celsius:~/FG-git$ qalc 100hp/\(25%*4.5kWh/kg\)
(100 * horsepower) / ((25 * procent * (4.5 * kilowatt * hour)) /
kilogram) = approx. 18.412345(g / s) 
arnt at celsius:~/FG-git$ qalc 100hp/\(25%*4.5kWh/kg\) to kg/h 
(100 * horsepower) / ((25 * procent * (4.5 * kilowatt * hour)) /
kilogram) = approx. 66.284443(kg / h) 
arnt at celsius:~/FG-git$ 

..is "@ 1800 rpm" relevant?  Only if it impacts your efficiency. ;o)

  Scenarios always come in sets of three: 
  best case, worst case, and just in case.
