Abstract: A system for removing snow from easily damaged surfaces such as artificial turf athletic fields includes a modified snow blower used in combination with a vehicle towing a sled. The sled can be a large polymer sheet with side straps and draw bars at one or both ends. The sled also includes tow straps or other attachments for coupling to the vehicle. The snow blower, which can be independent or driven by another vehicle, is modified to cover its cutting edge with an edge guard and to include a set of wheels behind the auger housing. In operation, the snow blower can travel alongside the vehicle and sled and discharge snow onto the sled. When desirable, the sled can be towed to a snow discharge area and emptied. For best results, the snow blower should travel at a constant speed while the sled travels at a variable speed.

Abstract: A Fuel Fractionation System (FFS) and associated methods to generate and store a fuel for internal combustion engines is provided. FFS provides a distillation column assembly to distill liquid fuel to form a volatile light fraction secondary fuel. The distillation column assembly includes a vaporization module to vaporize a feed fuel in the distillation column and includes a condensation module to condense heavy fraction components of the vaporized feed fuel. FFS also provides a controller positioned to control the vaporization of feed fuel in the distillation column to thereby control the separation of the feed fuel into light fraction fuel and heavy fraction fuel components, and positioned to control the condensation of the heavy fraction components so that fuel exiting a light fraction output port in the distillation column is substantially light fraction fuel components by volume.
