Metal alloys have served as the proverbial backbone for car engines and jet turbines alike because of their high strength and ability to resist sudden temperature changes. Now a lighter, cheaper ceramic material that also resists temperature changes may become a viable replacement for expensive metal, according to New Scientist.
How much is 0.17 cubic inches worth to you? If your name is Carl Long, the answer is: much more than $200,000. That's the monetary fine (the largest in NASCAR history) that Long received last week for running with an engine that was 358.17 cubic inches in volume, just 0.17 inches above the NASCAR limit. For Long, who was in 63rd place before the suspension, the fine is just the beginning.
A unique engine prototype cuts emissions and consumption without sacrificing power

Earlier this month, we told you about an alternative oil for 2-stroke engines made from beef tallow. As you may remember, 2-stroke engines are tiny and powerful, but inefficient and heavy polluters. For years, engineers have tried to combine the efficiency of a 4-stroke engine with the power of a 2-stroke, only to come up short because the technology was simply not yet advanced enough. A team of UK researchers have finally solved that puzzle with a prototype they call the 2/4SIGHT.
