A Sustainable Engine Weighing Less Than a Backpack
Israeli – IAn Israeli engineering firm, Aquarius Engines, has developed an internal-combustion engine capable of running up to 7500 miles without refueling. The cylinder design with a double-sided piston decreases friction, allowing for greater efficiency. The engine is also extremely light, weighing less than a backpack. The engineer behind the design says the engine could even be used as a backup generator. Moreover, Aquarius Engines claims that the cost of the engine could be as little as €90. This means it could support developing regions in Africa and Asia if used as a general power supply.
