The idea behind a simple solid-fuel rocket is straightforward. What you want to do is create something that burns very quickly but does not explode. As you are probably aware, gunpowder explodes. Gunpowder is made up 75% nitrate, 15% carbon and 10% sulfur. In a rocket engine, you don'...
You might notice that the SLS here performs much better than the Space Shuttle in terms of emissions to payload capacity because the SLS has a much greater payload capacity than the Shuttle, mostly because the Shuttle had to lug the massive orbiter into orbit, which was not considered part of...
As much as any other factor, it set the brutal, unrelenting tone of World War I and World War II, as well as most of the wars since that time. Unlike earlier guns, which had to be manually loaded and fired, with this machine, one soldier could shoot hundreds of bullets every minute...
Calories in minus calories out equal weight gain. Time has proven this theory wrong over and over again, yet still, we think that if we can only starve ourselves that much more, we can get thin and healthy. It’s time to learn otherwise. ...
The sulfur and charcoal fuels that come in the kit are already ground fine enough for the rocket fuel, and can be used as is. Using a popsicle stick, weigh out the ground up potassium nitrate (KNO3) into a weighing cup placed on a digital scale. Add it to a plastic baggie. Use the...
“i could egress from a rocket powered prototype and survive.” “sam is the new generation. he’s the kid that’s dreaming big and i love that—people pursuing dreams at all cost,” clark says. but he does wonder if cossman might be underestimating some of the complexities. spacesuits...
When it comes to making life work, plants might get all the good press, but it's the much-maligned microbe that holds the food chain together. Specifically, cyanobacteria help form its base; gut microbes help us digest food from it; and soil bacteria turn the resulting waste into nutrients...
FIRSTLY, WOULD VERY MUCH APPRECIATE IF YOU WOULD BE ABLE TO TELL the ACTUAL COLOUR OF CONCENTRATE; I HAVE BEEN TABLING ORE FROM VARIOUS VEINS AND WOULD VERY MUCH NEED SOME ASSISTANCE ON AQUA REGIA LEACHING METHOD. VERY MUCH THANK IF YOU ARE ABLE TO ADVISE OR EDUCATE ME IN THIS MATTER ...
sulfur, phosphorus, oxygen, hydrogen, and gallium, would be worth at least $2 trillion. If humans mined all of Amun, therefore (which would take many years), the gross profits would come to at least $22 trillion. It is difficult to estimate the upfront costs of such a mining operatio...
“I can recycle nitrogen. I can recycle the sulfur. I can recycle basically all of the carbon that right now is creating all the greenhouse gas issues.” Even though agroforestry is not the most popular form of agriculture in places like the U.S., it's actually quite doable. These ...
