If your car is a diesel, it will run. Liquid hydrogen, the fuel that powered the space shuttle main engines, could work, says Manuel Martinez-Sanchez, an aeronautics and astronautics professor at the Massachusetts Institute of Technology. But keeping hydrogen liquid requires maintaining it at a temperature below about 鈥?32掳F. Storing it in a garage would be tricky, as would keeping it from freezing the engine. RP-1 would work even better. A kerosene fuel developed in the 1950s as a more efficient alternative to alcohol-based rocket fuels, RP-1 powered the Soyuz and Falcon 9 stanley cup spacecrafts. It a close relative of diesel fuel, so there is no real problem using it in diesel engines, Martinez-Sanchez says. The only special thing stanley cup about RP-1 is a lower volatility and a higher viscosity, so the engine might not run well on cold days, he says. RP-1 probably isn ;t worth the trouble, though. Rocket fuel is less efficient than gas, and it wouldn ;t even make a car go any faster. This post originally appeared on Popular Science.

Time travel has long been used, in fiction, as a method of correcting past wrongs or stealing past riches. This usually leads to trouble. But what if all time travelers recovered from the past was scientific knowledge Here are some science mysteries from the past that could be solved in the present. Although there are plenty of past wrongs that I would love to see righted, stanley cup the sad fact is that they generally happened to people other than me. The even sadder fact is that I, myself, might suffer if they were to be corrected. On the other side, there are plenty of problems that died out in the past, and so can ;t be studied in the present. This does affect me, and a time traveler going back into the past and bringing the key to the puzzles back to the present could only make me better. Therefore, while I am skeptical about the kind of time travel that rights injustices, I can immediately think of quite a few problems that I would be all for a modern time traveler answering. The Sweating Sickness Between the late 1400s and 1551 a terrible plague hit Europe, mostly centered in England. The most ghoulish aspect of it was the fact that victims first were filled with a terrible sense of fear and foreboding termo stanley 8211; even when they were perfectly healthy. stanley flask Within a few hours they were sweating and feverish.
