- No, that's not the problem. You could probably do a day's drive on a
- toilet-flush's worth of water.
-
- It'd have to be distilled, though, and perhaps even chemically treated. That
- means you'd have to buy it at the store or at the gas station, and that means
- you'd have TWO fluids to replenish periodically. That, and distilled water
- is $.60/gal.
-
- Inconvinience. That's all.
-
- It's the same thing with the electric heater for wintertime. Maybe the real
- men in the Tater State don't mind, but little inconviniences like that (ec. the
- Stanley Steamer's pilot light) doom a design.
-
- Furthermore, you can't plug your car in at a parking lot. And a solar panel
- wouldn't work at night.

- They key to this thing seems to be using the least amount of working fluid:
- Reducing the amound of water used:
- Reduces condneser size.
- Speeds startup.
- Leaves us with less water to keep from freezing--less energy to keep warm.
- Makes for a more efficient, low-volume, high-temp, high-pressure system.
-
- "Knee-jerk engineering" tells me that we could create an even lower volume
- system that those today by utilizing:
- Super-skinny tubing (pencil-diameter) with lots of fins.
- Extreamy meticulus computer control of the feedwater pump.
- Very high compression-ratio engines with precision geartrains.
