Chinese Astronauts Demonstrate Fire in Space on Tiangong Space Station (Video)

Chinese astronauts conducted an experiment aboard the Tiangong space station, lighting a candle to demonstrate how flames burn in microgravity. The flames appeared nearly spherical, unlike the teardrop-shaped flames on Earth due to the weak combustion convection current in the microgravity environment. The live lecture, part of the "Tiangong classroom" series, showcased various microgravity phenomena and highlighted the differences in physical processes between space and Earth. The experiment would likely be met with surprise by International Space Station participants, who have strict rules regarding flammable materials and open flames.

"Breakthrough: Scientists and Chemical Engineers Unveil Fire-Safe Fuel"

Chemical engineers at UC Riverside have developed a fire-safe fuel that only ignites with the application of electric current. The fuel, based on an ionic liquid, does not react to flames and eliminates the risk of accidental fires during storage or transport. By controlling the vapor, the researchers were able to control whether the fuel burns. The fuel could potentially be used in any type of vehicle, but further testing and research are needed before commercialization. While the cost may be higher than conventional fuels, the safety benefits make it an attractive option.

Transparent Resin Engine Runs Briefly in Mesmerizing Display

Garage 54 attempted to create a transparent engine block based on a four-cylinder engine from an old front-wheel-drive Lada by casting it out of resin. The engine was assembled with regular Lada head, crank assembly, and other relevant components. However, the engine block shattered after the first power stroke, sending shrapnel flying across the workshop floor. The team notes that some manufacturing issues may have been part of the problem, but the concept could work with a stronger block running at lower compression with more careful fuelling.
