In rods, this chemical is called rhodopsin; in cones, these chemicals are called color pigments. NaCl is the chemical formula for what? Rather than clean the toilet, dust the shelves, and wipe down the countertops, you can instead unwind on the couch, curled up under a blanket, maybe pour yourself that glass of wine you’ve been thinking about, and start that new TV show everyone’s been talking about. What can you use to cool the radiator? That said, if there really is no other solution, you can fill a container with urine and put that in your radiator to try to cool it down long enough to get to a garage. How can you deal with icy windows? We have a thriving Internet culture, an unprecedented understanding of the natural world and we can even watch episodes of “America’s Next Top Model” on our mobile phones. But of course, the world is ever in transition, and we currently find ourselves suspended between two ages: a time dependent on fossil fuels such as oil and coal, and a future dominated by renewable energy sources.

Options vary on just how dependable some of these renewable energy sources are, as well as how well they’ll be able to sustain us in a post-fossil fuel era. To maximize power and efficiency, hydrogen is injected into the intake manifold as late as possible, so the injection valves have been redesigned, as well. Let’s say your car is overheating, your phone is dead, you have no water, and you’re miles from civilization. Rinse the carpet with 1/2 cup vinegar per gallon of water, going slowly and extracting all the moisture thoroughly. But if you get locked out in the middle of nowhere or, worse, you’re trapped inside the car as it sinks in water, you may need to break that glass. The ceramic of a spark plug thrown at a window is incredibly effective at breaking car window glass. It’s environmentally friendly. BMW’s H2R (Hydrogen Record Car) is powered entirely by the clean-burning process of liquid-hydrogen combustion, and this next-generation racecar has already set speed records in its class. Because of an interesting safety setup, it is impossible for hydrogen gas to leak into the air during the refueling process. As an additional safety precaution, the combustion chambers are cooled by air before the hydrogen/air mixture flows into the cylinders to ensure that it won’t ignite in an uncontrolled manner.

To prevent possible leaks in the jacket around the fuel tank, which helps maintain the liquid hydrogen at a sufficiently low temperature (hydrogen takes its liquid form at -423F/-253C), the H2R features a double-redundant safety system: If the pressure within the tank ever exceeds 5 bar, two additional safety valves open up immediately. This gaseous hydrogen exerts a higher pressure inside the tank. The condensation of the gaseous hydrogen reduces the partial pressure inside the tank, so no hydrogen escapes while the tank is being filled. Hydrogen is added to the H2R’s tank at a mobile hydrogen filling station through a manual tank coupling. The fuel tank is topped with a speedometer, tachometer, and matching filler caps. According to the BMW Web site, the company’s long-term goal is to eventually replace the cars that run on atmosphere-polluting fossil fuels with vehicles that use clean-burning, liquid-hydrogen fuel. Whereas other carmakers have gone the route of hydrogen fuel cells, BMW has opted for a more traditional-style engine that utilizes a nontraditional fuel.

So why is BMW expending copious amounts of time, money and energy to spearhead the production of hydrogen-powered vehicles? Conceived and developed in only 10 months, the H2R features a 6.0-liter, V-12 hydrogen-powered engine. Combo Cleaner primarily focuses on malware removal and system optimization, but it does not provide file recovery features. Although more difficult to repair, the dual belt system provides clean, quiet, and mostly trouble-free operation. The 1982 Harley-Davidson FXB Sturgis motorcycle was fitted with toothed belts instead of the typical chains, providing a clean, quiet ride. As denoted by the “FX” prefix in the nomenclature, the FXB is based on the Low Rider chassis and engine. One week each summer, the town of Sturgis teems with bikers from around the country, and in 1982, Harley-Davidson decided to commemorate the event with the release of the FXB Sturgis. Like virtually all of Harley’s early customs, the Sturgis is now a collector’s piece.
