New track blower, uses vacuum

After six months of research and a year of development, Rob Brush believes he has a better alternative to help dry race tracks. The project manager for a steel fabrication company in Canada has designed a track dryer that travels about twice the speed as the current jet dryers used at NASCAR tracks. Rather than just blow hot air on the track as the jet driers do, Brush's vehicle also uses a vacuum to suck up water akin to a Shop-Vac. "With eight of these units at Daytona International Speedway, we could dry the track in under an hour," Brush said, estimating he could cut the current drying time in half. Brush has built a prototype that was given a successful trial run by NASCAR when a shower followed Sprint Cup qualifying at New Hampshire Motor Speedway two months ago. Brush is expecting to meet with NASCAR officials in Daytona Beach, Fla., in two weeks before bringing the prototype dryer to the season finale at Homestead, Fla. The invention could be a boon for NASCAR, which has been plagued by rain this year (three Cup races were delayed a day and three were shortened by bad weather). The dryer also would fit with NASCAR's green initiatives because it runs on propane. Brush estimates it would burn less than 500 gallons to dry Daytona vs. 3,000 gallons of jet fuel. Brush has attended several races over the past two seasons, taking nearly 4,000 photos in researching the dryer. USA Today
