NuVinci Transmission Invention Draws $25M in Financing

This could be adapted to any rotating shaft to improve efficiency.
“The NuVinci CVP can be used in virtually any transmission-based vehicle or device–from bicycles and outdoor power equipment to cars, trucks and wind turbines. It is already on track to expand the number of bicycles used for transportation and it enables the design and manufacture of a wide range of electric and hybrid vehicles that have the speed, range and hill-climbing capability to be genuine transportation alternatives. The NuVinci CVP uses a set of rotating and tilting balls positioned between the input and output components of a transmission. Tilting the balls changes their contact diameters and varies the speed ratio. A study conducted by the National Renewable Energy Laboratory (NREL) showed that, when used in a wind turbine, NuVinci technology can reduce the cost of producing energy. Since coming into the market in late 2006, market acceptance and penetration for the NuVinci CVP has increased steadily–particularly in the bike and electric vehicle industries, and especially in Europe. “NuVinci technology has enormous potential to add value in the bicycle, electric vehicle and automotive industries,” said Keimpe Keuning, senior investment manager at Robeco. / The NuVinci CVP is a new, revolutionary class of CVT transmission that gives LEVs real-world performance and makes them genuinely competitive with gas-powered vehicles. It offers seamless shifting over an “infinite” number of ratios. And it dramatically improves acceleration, hill climbing and top-end speed while extending range and battery life. Best of all, it offers vehicle designers the ability to affordably create LEVs with performance and capabilities never before possible!” – Source
