From what I've heard from 32 Old Slip, the reason for thier generators to fail was that the intake filters were clogged from the concrete dust in the air.
Hmmmm.... although this situation is far from one's typical power outage, maybe one should not rely on the radiator. Ass-u-ming that one has a steady supply of water: s/radiator-cooled water/external water supply/ It works the same. The only purpose of the radiator is to facilitate cooling _without_ an external water supply, to reuse the existing water. Yes, a contastly-flowing external water supply is wasteful. So we make it "emergency only". Note that the numbers represent thermostat temperatures in degrees Fahrenheit[1], and the arrows signify flow direction (check valves and water pump omitted for simplicity): ~~~~~~ supply ~~~~~~ | V +------<------+ | | V | +--------+ | | engine | ^ +--------+ | | | V | +-----+ | | 165 | ^ +-----+ | | | V | +----------+ | | radiator | ^ +----------+ | | | V | +-----+ +------>------+--->----| 195 | +-----+ | V ~~~~~ drain ~~~~~ [1] Apologies to the standards-abiding, metric-loving people out there. I just don't feel like converting right now. :-) Save for the high-temp thermostat and the external water supply, it looks remarkably like a standard system with overflow. The big disadvantage to this design is that, if one runs out of water, this _will_ overheat. But overheating is imminent when the high-temp thermostat opens (a prerequisite for running out of water), so we were SOL anyway.
