Can A Motorized Bicycle Run On Trees?
Some of the earliest automobiles weren’t powered by refined petrochemicals, but instead wood gas. This wood gas is produced by burning wood or charcoal, capturing the fumes given off, and burning those fumes again. During World War II, nearly every European country was under gasoline rations, and tens of thousands of automobiles would be converted to run on wood gas before the war’s end.
In the century or so since the first car rolled on wood gas, and after hundreds of books and studies were published on the manufacturing and development of wood gas generators and conversion of internal combustion …read more
Teardown: D50761 Aircraft Quick Access Recorder
Everyone’s heard of the “black box”. Officially known as the Flight Data Recorder (FDR), it’s a mandatory piece of equipment on commercial aircraft. The FDR is instrumental in investigating incidents or crashes, and is specifically designed to survive should the aircraft be destroyed. The search for the so-called “black box” often dominates the news cycle after the loss of a commercial aircraft; as finding it will almost certainly be necessary to determine the true cause of the accident. What you probably haven’t heard of is a Quick Access Recorder (QAR).
While it’s the best known, the FDR is not the …read more
Construction Cranes Versus Hurricanes
When engineers are designing buildings, bridges, or other large construction projects, a lot of thought is given to the environment. Some of these considerations might seem obvious, like designing a skyscraper in San Francisco to tolerate earthquakes, building a stadium in New York City to hold up not only its own weight but the weight of several feet of snow on the roof, or constructing bridges in any coastal area to be able to tolerate salt spray. Not everything is this straightforward, though. Not only do the structures themselves have to tolerate the environmental conditions they are in, but the …read more
International Space Station is Racing the Clock After Soyuz Failure
Today’s failed Soyuz launch thankfully resulted in no casualties, but the fate of the International Space Station (ISS) is now in question.
Just two minutes after liftoff, the crew of the Soyuz MS-10 found themselves in a situation that every astronaut since the beginning of the manned space program has trained for, but very few have ever had to face: a failure during launch. Today the crew of two, Russian Aleksey Ovchinin and American Nick Hague, were forced to make a ballistic re-entry into the Earth’s atmosphere; a wild ride that put them through higher G forces than expected and …read more
