Rev C+
One field. Two products.
Mirrors that stay. A cold tile for daylight electricity and warm water. A dark tile for factory heat that can be stored. A turbine only if it earns the tank.
What we are trying to achieve
Replace the gas a factory already burns, with heat we can hold past sunset. That is the product. It does not need a generator to be worth building.
Electricity is allowed in two places, and they are not the same place. Daylight watts come off the cold tile while the sun is on it. Night watts, if they ever exist, come out of the hot tank through a machine on the ground. Adding those two numbers together and calling it a house is not allowed.
We are not trying to beat a silicon roof at the wall outlet. That fight is already over.
The rule
The field stays. Receivers split. Turbines compete.
Heat still has value if every expander fails.
Match energy quality to the load. Do not spend 300 °C oil on a job 65 °C water can do.
The plant, in four parts
- Field
- Cheap linear-Fresnel mirrors. They stay for decades. They do not care which tile is on the rail.
- RC-E
- A cold tile. Concentrated light becomes daylight DC. The cooling water leaves warm. That water is not factory oil.
- RC-T
- A dark tile. Oil leaves at factory temperature, 250–390 °C, and goes into two tanks.
- PB-01
- Optional, on the ground, after the tanks. A scroll is the baseline. A disc has to beat it. Heat still ships if neither does.
One noon, so the size is obvious
One hundred square meters of mirror, 900 watts per square meter of direct sun, sixty percent of the acres on the cold tile. This is a scenario, not a measurement, and not a year.
| Sun on the field | 90 kW |
|---|---|
| Cold tile / oil tile | 60 m² / 40 m² |
| Daylight DC, before the inverter | 9.4 kW |
| Factory heat in the oil | 16.2 kW |
| Later, gross, from the tank | 2.4 kW |
The oil figure is 45% of the sunlight on the oil acres. That band already includes the mirrors. Counting the optics a second time is how an earlier draft got about 10 kW. Do not put it back.
If every acre is oil instead, the same noon is 35–45 kW of heat, and 3.5–9 kW gross through a small cycle. That is the old envelope. It is not the default plant. The three numbers above are not added into one.
What this site will not do
- No interactive toy of the disc, the tube, or the sun. The drawings are the pictures.
- No frozen 60/40. That row above is one scenario. The split is a choice, f_E + f_T = 1.
- No 47.6% laboratory cell, and no 95% turbine. The cell model is 24–32%, default 28%.
- No annual kilowatt-hours for a split field until that year is actually rerun.
- No claim that any of this has been measured.
