Synthetic Ice Gets Closer to the Real Thing

Synthetic Ice Gets Closer to the Real Thing Synthetic Ice Gets Closer to the Real Thing Synthetic Ice Gets Closer to the Real ThingHockey players, figure skaters, and terrified beginners hugging the wall as they go round-and-round know the troubles that come with skating on ice. For one thing, its cold. If you want to do it outdoors, youre restricted to very cold weather. For skating rink operators, theres the issue of energy costs. Keeping water in its solid state amounts to the largest bill for rink owners, and while a Zamboni at work is a pleasure to behold, ice doesnt stay slick without it.All these downsides evaporate when ice is replaced with plastic.The first plastic synthetic rinks, which hit the skate scene in the 1970s, were somewhat better than skating on concrete. But they had to be coated with lubricants to be slippery and gave off a lot of shavings as skate blades cut across them.Now, using more advanced materials and techniques, companies like Glice are making syntheti c ice that is more like the real stuff than ever before.Glice co-founder Toni Vera, a hockey player and engineer, skated on an early version of synthetic ice in Canada, years ago. He came back from that trip and he couldnt get it off his mind, said Viktor Meier, the companys CEO and co-founder.For You Cockroaches Inspire Tiny Robots that Fly, Walk, Swim, DiveThis first outdoor ice rink in Brazil is made with environmentally friendly synthetic ice. Image GliceIn fact, it stayed on his mind for eight years. During that time, Vera experimented with self-lubricating polymers, to find the right ingredients to best approximate real ice. On traditional rinks, skates melt the ice as they slide over it, essentially creating a thin track of water. With Glice, skates release lubricants in the polymer instead. The exact formula remains proprietary, but the polymers that make up Glice, which fall between high and ultra-high density, are made with silicone and other additives.To best reproduce th e experience of skating on the real thing, Glice engineers had to do more than just aim for ices coefficient of friction. Instead, they repeatedly had skaters test out different versions.In the end, the sensation is always subjective, Meier said. There are different complex factors that work together maybe if you get one number going up, another goes down. You can only get it by feeling it.Vera and Meier also abandoned the injection molding used by other plastic ice producers and switched to pressing. A long press time with high heat creates a higher density, which reduces shavings. It also means that, aside from micro-scratches, the surface stays smooth for the duration of its 13 to 15 years of life. After that you can flip it over and have a brand new rink, said Meier.Professional hockey players and figure skaters attest to Glices closeness to the real thing.I made it my goal to personally skate on every product I could and find the differences in each product, said Dan Fritsche, once a player for the Columbus Blue Jackets, the New York Rangers, and the Minnesota Wild, who is now Glices national director for the U.S. I found myself having more glide, easier and sharper turns, and an all-around better experience than any other product, hands down.Real ice may arguably remain king, but only when its at its freshest state, especially right after a Zamboni passes over it.After fifteen minutes, real ice is scratched but Glice stays the same.Toni Vera, Glice cofounderIn the first ten minutes, that fresh surface is better, Meier said. After fifteen minutes real ice is scratched, but Glice stays the same.But the company is still in competition with real ice, and they hope to eventually match the performance of ice at its cleanest and freshest. They are also working on making their product self-healing and dirt ejecting.In the six years of its existence, Glice has delivered ice to more than 80 countries. Now outdoor skating is available in balmy climates like Israel, Peru, Iran, and Dubai, among many others.Michael Abrams is an independent writer.Read MoreA Military Robot Has Fallen and It Better Get UpUnique Gas Turbine Engine Powers Quieter, More Reliable DronesThis Robots Mission is to Solve the Worlds Water Crisis
