How Co2 could be the future of fuel As climate deniers and their allies in industry and government thwart conservationists’ efforts, some scientists are working to develop a back-up plan: use technology to “geoengineer” the Earth's atmosphere and reduce the impacts of climate change.
European Space Agency Horizons mission – Soyuz launch Watch the launch from inside the crew capsule with first-ever shots from outside the spacecraft recorded by cameras fixed to the exterior of the Soyuz. The intense launch lasts less than ten minutes whereby the Soyuz spacecraft is propelled 1640 km and gains 210 km altitude. Every second for nine minutes, the spacecraft accelerates 50 km/h on average as the rocket’s boosters burn their fuel and are discarded.
840HP Dodge Demon vs 710HP McLaren 720S Drag Racing 1/4 Mile The Demon crate finally came in and we run the 1/4 mile! We race the Dodge Demon equipped with the race gas ECU, 100 octane fuel, race air filter, skinnies up front and Mickey Thompson tires in the back vs a McLaren 720S.
Primitive Technology: Blower and charcoal I made a blower and some charcoal at the new area in order to create higher temperatures in for advancing my material technology. I took Fan palm leaves and fashioned them into an impellor (about 25 cm in diameter) held in a split stick as a rotor. I then built a housing from clay (slightly more than 25 cm diameter with inlet and outlet openings about 8cm in diameter) and assembled the blower. I opted not to make a bow or cord mechanism as I’ve done before due to the complexity and lower portability of such a device. The lighter impellor material (leaf instead of the previous bark) made it easier to spin by hand anyway as it has a lower momentum. Each stroke of the spindle with the hand produces 4 rotations, so about 2 strokes per second gives 480 rpm. The blower increases the heat of a fire when blowing into it and I would guess it’s more effective than a blow pipe and lungs but don’t how it would compare to a primitive pot or bag bellows for air supply. A small furnace was made and then fired with wood fuel. The wood was wet but managed to fuse and partially met sand in the furnace.
How to Land the Space Shuttle… from Space Presented on Halloween (October 31st) at Stack Overflow’s 2016 Remote Meetup in Philadelphia. This was one of nine "Tiny Talks" given over three days at the meetup. Every year, employees submit Tiny Talk ideas on a wide range of topics (some completely random and not company-related at all, like this one) and we vote on which ones we want to hear. So, thank you to my coworkers for voting me in. Original proposal description I submitted for this talk: Let's say you're traveling at about 17,500 miles per hour (28,000 km/h) in low earth orbit, your main engines are out of fuel, and it's your job to guide the spaceship through a fiery re-entry without burning up or skipping out of the atmosphere, navigate to your landing site, and arrive with just enough energy to make an unpowered landing on a runway which is halfway around the planet from where you started. And, of course, either you succeed on your first try, or everyone dies. So, no pressure…. In this talk, I'll show you how space shuttle designers, pilots, and autopilots managed to do just that.
F-16 full afterburner F-16 engine test with full afterburner. 11 liters of fuel per second!
Timber A group of logs is about to freeze to death in a cold, icy desert. When they realize that the only fuel for a warming fire is their own body, things start heating up.
Primitive Technology: Natural Draft Furnace I built a natural draft furnace to test ideas about how hot a furnace could get without the use of bellows. Natural draft is the flow of air through a furnace due to rising hot air. The hot gasses in the fuel bed are more buoyant than the cold air outside the furnace causing them to rise. Fresh combustion air then enters the base of the furnace to replace the rising combustion gasses, keeping the fuel bed burning. This effect increases with: 1. the average temperature of the fuel bed relative to the outside air and 2. The height of the furnace. Two other important factors are the size of the tuyere (air entry pipe) and lump size of the fuel bed as these effect the resistance to airflow through the furnace. The furnace was tested with wood fuel and some ore was melted but produced no iron. High temperature were indeed produced (probably about 1200 c). These types of furnaces were once used for smelting copper and iron ores in around the world in ancient times, usually using charcoal as a fuel and in some cases wood too.
Nuclear Reactor Pulse and Startup Compilation The blue light is known as Cherenkov radiation. It is similar to a sonic boom, but instead of an object travelling faster than the speed of sound, a charged particle is travelling faster than the speed of light in a medium. In this case, the speed of light in water is roughly 75% the speed of light in a vacuum. It tests the time-dependent properties of the fuel. Engineers use that data to predict what would happen if there were an accident at a large reactor Cherenkov radiation, also known as Vavilov–Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation.
Essentially when light passes through different materials its speed can be slowed as the photon makes it way through the medium.

Stealing Gas From a Truck Occurred on July 15, 2017 / Palmer, Alaska, USA "It was approximately 6 am last Friday when I caught this woman siphoning fuel out of a company vehicle. I confronted her and called the police who in turn found her a few miles away. They let me know the vehicle was also stolen. So this dummy was stealing gasoline for a stolen car."
