Re: Difference between alcohol & kerosene stove?
We lived with a pressurized alcohol stove (similar in principle to kerosene - ie preheat/light/use) for 10 years or so. Finally switched to Propane and never looked back. Used with common sense, a good appliance and good practice it's quite safe. Aside from ease of lighting and faster cooking, the fumes and high cost of the proper fuel was a major PITA with the pressure alcohol.
We've sailed with friends who use the wick type alcohol stove like Gary posted above, they are a much better idea, but still slower than propane and somewhat less convenient. However they do lack the power draw that a proper solenoid-equipped propane system has.
But we'd never go back to a pressurized system that required pre heating etc like kero or alcohol.
