rx7 Mug

Tech stuff: A four-stroke engine's cylinder fires only once every two revolutions. A two-stroke's cylinder fires every revolution, so a 2-stroke has (all things being equal) double the output for the same cylinder size. Problem is that 2-stroke petrol engines don't scale up in size well (though some industrial Diesels *are* 2-stroke). The rotary fires (like the 2-stroke) once for each revolution, so it has potentially twice the output for the same volume as a 4-stroke, plus the rotary *does* scale up OK. Piston engines absorb energy during the compression cycle, giving a negative torque, but rotaries provide positive torque for each entire revolution, since compression, power and exhaust occur simultaneously. Rotaries can run to very high rpms compared to piston engines because their motion is continuous rather than reciprocating and because the few rotating parts are small-ish and can be made very robust, while piston engines are limited to lower and lower rpms as they scale up. Rotaries are thirsty if you cane them, but I get 30 mpg touring at 70 mph in my 1985 Series 3, no mods. Fuel consumption is an issue - it's to do with the combustion space being a long, thin rectangle, rather than the more ideal cylindrical space of a piston engine. And having a turbo giving over 270 shaft HP from a 1.3 litre engine has got to be a temptation.... But no, NOTHING else in the car park looks as damn sexy!

I got this for my dad but he didn’t want it so he just gave it to me. Ever since I took it back my life has been the greatest it’s ever been. I asked my other dad if he wanted but he said no too. Oh well, I get to enjoy this product for myself more.

War. War Never Changes. War, war never changes. In the year 1945, my great-great grandfather, serving in the army, wondered when he get to go home to his wife and the son he never see. He got his wish, when the U.S. ended WWII by dropping an atomic cloud on Hiroshima and Nagasaki. The world awaited Armageddon, instead, something miraculous happened. We began to use atomic energy as a nearly limitless source of power. People enjoyed luxury once thought in the realm of science fiction. Domestic robots, fusion powered cars, portable computers. Then, in the 21st century, people awoke from the American dream. Years of consumption led to the shortages of every major resource. The entire world unraveled. Peace became a distant memory. It is now the year 2077, and we stand on the brink of total war, and I am afraid, for myself, for my wife, for my infant son, because if my time in the army taught me one thing; is that war, war never changes.

Excellent satire - didn't see comments to that end, so find it hard to fathom if most readers, in turn, didn't laugh out loud, and say so. But apparently not.

Michael T. Apr 28

I am gonna buy it and give it to my nine year old brother
