Super Heater to Heat Storage Size 3 2400kwh
In Design Strategy it was shown that as a starting point for a railway SHE:
Calculation Size 3:
A. 4 trips/hr * 100kwh/day * 6hr = 2400kwh/day
B. 4 trips/hr * 200persons/day * 6hr = 4800persons on the 50km round trip per day.
C. 4 trips/hr * 44.44m² * 6hr = 1066.6m² concentrator area.
D. Amount to be collected 2400kwh * 2 = 4800kWh
E. At 70% efficiency: 4800kWh * 0.7 = 3360kWh to the heat storage.

| Function | value |
| At 70% concentrator efficiency, the required amount of heat energy in the Heat Storage (HS) 4800kwh/day * 0.7 | 3360kWh/day |
| Total amount in GJ: 3360kWh * 3600s | 12.1GJ/day |
| From the 3360kWh/day of input energy 38% is to be recapture at the turbine output, returned to and restored in (HS) and reused: 3360kWh/day * 0.38 is the estimated amount to be recaptured. | 1277kWh/day |
| Total amount in GJ: 1277kWh * 3600s | 4.6GJ |
