In 2003 Popular Science asked readers: "Will most Americans be driving hydrogen-powered cars by 2015?"

No one wants to be the first to discover the use of a chemical weapon on a battlefield, but if anyone must have that job, the new Par Chemical Biological Radioactive Nuclear (CBRN) Reconnaissance Vehicle is the car to do it in.

China's most powerful aircraft engine, the WS-20, is getting closer to finishing its tests. With a power output of 14 tons, the WS-20 will replace the less powerful and less efficient Russian D-30KP, which has only 10.5 tons of thrust. The WS-20 turbofan has been flying on this Il-76 test aircraft since 2014, and it's likely that aerial testing will wrap up in late 2015.

On Monday, 27 tanker cars carrying oil from North Dakota derailed in West Virginia. The train had 109 cars and was carrying 3 million gallons of crude oil. Nineteen of the cars, each capable of holding thousands of gallons of crude, caught fire, and despite freezing weather and snow, several small fires were still blazing on Thursday, days after the crash, with emergency responders deciding to let the flames burn themselves out.

Whenever a radical new technology promises to change our way of life, it's only a matter of time before Hollywood finds a way to turn it into a comedic farce. Case in point: cars that drive you to your destination.
