Tudi navadni kalorifer (fen za lase, oljni radiator, močno reklamirani infra grelni panel, ...) ima 100% izkoristka = čisto vsa porabljena elektrika se pretvori v toploto.vili napisal/-a: nam je pa govoril en profa elektrotehnike, da imajo transformatorji najboljši izkoristek, najmanj izdub..., dobro grelniki gredo blizu 100...

The Royal Society of Chemistry read the claims about Eugene Houdry, and his process at the Sun Oil Company, in a paper written originally for the journal Invention and Technology by American science writer Tim Palucka.
The introduction to the paper by Palucka says of Houdry: "His miraculous catalyst turned nearly worthless sludge into precious high-octane gasoline and helped the Allies to win World War II."
He continued: "That process would make a crucial difference in mid-1940 when the Royal Air Force started filling its Spitfires and Hurricanes with the 100-octane gasoline imported from the United States instead of the 87-octane gasoline it had formerly used."
"Luftwaffe pilots couldn't believe they were facing the same planes they had fought successfully over France a few months before. The planes were the same but the fuel wasn't," said Palucka.
"It is an established fact that a difference of only 13 points in octane number made possible the defeat of the Luftwaffe by the RAF in the fall of 1940. This difference, slight as its seems, is sufficient to give a plane the vital edge in altitude, rate of climb and manoeuvrability that spells the difference between defeat and victory.
