According to the UN, there are about 258 million widows in the world. Tomasin Racing feels these are rookie numbers, so it's making a kit that turns a standard Honda CRF 450 into a certified widow production facility with a 500cc 2-stroke engine.

Most robots use electric actuators, but this little fella packs a lot more punch. Researchers have created a new type of minuscule combustion engine that gives this tiny frog robot explosive leaping abilities, as well as fine movement control.

The US Naval Research Laboratory has funded a groundbreaking project to develop a new hypersonic engine capable of morphing its shape during flight to optimize power, thrust and efficiency. It's now entering experimental testing in Florida.

GE once thought super-efficient propfans were the future of air travel, until low fuel prices in the late 1980s moved fuel consumption down the list of priorities. Now, it's bringing them back with the CFM Rise, promising 20% fuel savings.
-
Rolls-Royce has completed the first ground tests on its massive UltraFan engine, claiming it's at least 10% more efficient than any other large aero engine in service today. This carbon/titanium beauty will roll out on airliners in the 2030s.
-
LiquidPiston says its new XTS-210 solves the efficiency, lubrication and fuel type issues of Wankel rotary engines. This supercharged, liquid-cooled two-stroke claims 5X the power of an equivalent size or weight diesel engine, and 3X the torque.

The race is on to find viable materials for building on other planets, and one team has (thankfully) moved on from its last creation made of blood and urine to unveil a new biocomposite brick that's not only much stronger but a little more palatable.
-
Rolls-Royce says it's finished building the first demonstrator for its massive UltraFan engine, which will eventually hit the skies in airliners to be developed in the 2030s. Testing begins soon, with expectations of a 25% leap in efficiency.

Hydrogen combustion engines offer a chance to go (nearly) green without losing the sound, feel and excitement of driving a noisy, mechanical, piston-driven engine. Toyota has been racing one, and now it's evaluating a prototype Corolla for the street.
-
Utah's Transcend Energy Group claims it has a relatively simple and cheap way to dramatically increase the torque output of combustion engines, simply by replacing the standard connecting rods with new two-piece designs with a secondary joint.
-
UNSW researchers have prototyped and tested a retrofit system that converts diesel engines to run on 90% hydrogen, radically reducing both carbon dioxide and nitrous oxide emissions while boosting efficiency by an impressive 26% in the process.
