September 2018 27 I n f o r m a t i o n R e q u e s t # 4 0 9 Though the new Mean Mower, a modi- fied HF 2622 lawn tractor with a motor- cycle engine that generates more than 190 horsepower, is hoping to beat the speed record of 134 mph, it can still mow grass fast (the previous version could do so at 15 mph compared to traditional ride-on mowers that reach a top speed of around 10 mph). However, Consumer Reports found that to prevent tearing and bruising turf, 3.5 mph to 4 mph is the recommend - ed optimal mowing speed. Stanford graduate student Xinjian Shi, and a team of scientists, have been study - ing the possibility of reducing the cost to make hydrogen gas to use as a fuel source. To circumnavigate the problem of having to use expensive metals, such as platinum, in the production process, Shi has devel - oped a method of turning cheap, abundant metal sulfides into a material that replaces the need for the expensive metals. As battery technology improves, profes - sional equipment powered by them will become more common. For instance, researchers at Stanford University are working on making a new type of flow battery that would be capable of storing large amounts of renewable power created through solar sources. Their prototype was able to last for thousands of hours at double the voltage, but effective only at 392 degrees Fahrenheit. They are look - ing into a room-temperature battery in a reasonable size. Jeremey Wishart of the Propane Education and Research Council estimates that landscape contrac - tors are operating approximately 20,000 commercial propane mowers across the U.S., including those converted to propane. There are now more than 150 new models produced by 14 manufacturers in popular standard styles for landscapers to choose from. "We expect steady growth to continue in 2019 and beyond for a variety of reasons," states Wishart. One is that contractors are finding propane as the solution to increased gas prices.
