Suppose you used the tote bags bags with the lowest carbon footprint (the ones of nonwoven polypropylene) every time you went to the supermarket, and you conscientiously washed the bags with water heated by solar panels on your roof. It can be leather sling bags for women, travel tote bags, leather clutch bags, and the next day. Swap out your bulky suitcase for a streamlined travel bag. If you’re looking for a laptop bag that’s highly weather-resistant then the Timbuk2 Parker Commuter should be on your radar. Racing Radios is in charge of finding clear frequencies for everyone prior to the race and then assigning the frequencies to each team. If you have ever planted a garden of your own, then you know the pride that comes with growing your own food. Many of the bags have inner and outer pockets to keep you organized plus a zipper to make sure nothing falls out. We love the sheer number of pockets and zippered compartments that it has.
A small number of cadets in the National Guard and Reserves have been called to serve while enrolled in college, but that doesn't happen often, except say, in 1944, when the entire class of 1944 was called to fight in World War II. The teams pay a good deal of money for this peace of mind -- each tire's radio costs thousands of dollars, and each of the teams' 60 rims needs to have one! Teams will normally also reserve a frequency for the team's hospitality group (which provides food and such to team members and the team's guests) as well as to the team's marketing group. This is why, at any race, there can be upwards of 3,000 Motorola radios consuming hundreds of allocated frequency bands. Given that there are 25 cars and each team gets as many as 60 tires per race, Firestone is mounting up to 1,500 tires per event! During a race, the engine is exposed to incredible stress, so the engine is replaced after every race.
The engine control unit allows the transmission to shift gears without the driver lifting off the accelerator. Race control uses radios, as do the people who are working for the track. The driver will therefore move flagrantly once he has detected a fire to let other people know that there is a problem. But people play an important role, too. The engine is obviously a central part of a winning Champ Car. The engine burns methanol at a rate of approximately 2 miles per gallon, meaning that the car must make a pit stop for fuel approximately every 70 miles or so. As described in the section on the chassis, the engine is also a part of the car's structure. The company also emphasized being sure that the bags themselves had the proper clearances so they didn't rub against part of the car, and that they were clear of hot components like exhaust pipes and mufflers. The transmission is built by Xtrac, a very well-respected transmission company in many areas of automobile racing. The engine sits behind the driver, between the transmission and the tub that forms the cockpit of the car. Another feature of a Champ Car's engine and transmission is called Shift Without Lift, or SWOL.
Any CART racing team has a rather interesting relationship with its engine manufacturer. The teams are responsible for their own equipment, and many enlist the help of Racing Radios for purchasing equipment, service and accessories. The teams bring their rims to the Firestone area in the race paddock, where technicians mount and balance the tires. Each team has at least one member affectionately known as the DAG -- the Data Analysis Geek -- whose specific role is to pore over the reams of data a car produces during a practice run or a race and help the team use that data to maximize the car's performance. The rims are tested by X-ray and dynamic tests before they are allowed on the race course. If the driver runs over something (like debris from a wreck), he can talk to his pit crew, and they can check the tires immediately to see if any of them are leaking using the telemetry stream from the car (see the section on telemetry for details).
