Future of the car
In order to limit deaths, there has been a push for self-driving automobiles. There have been many notable efforts funded by the NHTSA, including the many efforts by the NavLab group at Carnegie Mellon University. Recent efforts include the highly publicized DARPA Grand Challenge race.
A current invention is ESP by Bosch that is claimed to reduce deaths by about 30% and is recommended by many lawmakers and carmakers to be a standard feature in all cars sold in the EU. ESP recognizes dangerous situations and corrects the drivers input for a short moment to stabilize the car.indigenous peoples of the americas internet and the workplace internet and the workplace laptop computer louis kahn
The biggest threat to automobiles is the declining supply of oil, which does not completely stop car usage but makes it significantly more expensive. Beginning of 2006 1 liter of gas costs approx. 1.6 US$ in Germany and other European countries. If no cheap solution can be found in the relatively near future individual mobility might suffer a major setback. Nevertheless, individual mobility is highly prized in modern societies so the demand for automobiles is inelastic. Alternative individual modes of transport, such as Personal rapid transit, could make the automobile obsolete if they prove to be cheaper and more energy efficient.marginalism market value definitions Mathematics maya civilization maya history
Hydrogen cars, driven either by a combination of fuel cells and an electric motor, or alternatively, a conventional combustion engine, are thought to replace fossil fuel powered cars in a few decades. The biggest obstacle for a mass market of hydrogen cars is the cost of hydrogen production by electrolysis, which is inefficient and requires a comparatively expensive source of electrical energy. However Hydrogen produces 5 times as much energy than 93 octane gasoline and promises to be cheaper with mass production and none CO2, but steam H2O emissions as result of the combustion. BMW's engineering team promises a high horsepower hydrogen fuel engine in it's 7-series sedan before the next generation of the car makes it's debut.media modernist critiques muscovite periods necklaces origins of the italian renaissance
The electric car in general appears to be a way forward in principle; electric motors are far more efficient than internal combustion engines and have a much greater power to weight ratio. They also operate efficiently across the full speed range of the vehicle and develop a lot of torque at zero speed, so are ideal for cars. A complex drivetrain and transmission would not be needed. However, despite this the electric car is held back by battery technology - so far a cell with comparable energy density to a tank of liquid fuel is a long way off, and there is no infrastructure in place to support it. A more practical approach may be to use a smaller internal combustion engine to drive a generator- this approach can be much more efficient since the IC engine can be run at a single speed, use cheaper fuel such as diesel, and drop the heavy, power wasting drivetrain. Such an approach has worked very well for railway locomotives, but so far has not been scaled down for car use.Pre-Columbian South America rain forests renaissance sculpture and painting Space exploration spanish conquest of mexico
Recently the automobile industry has determined that the biggest potential growth market (in terms of both revenue and profit), is software. Cars are now equipped with a stunning array of software; from voice recognition and vehicle navigation systems to in-vehicle distributed entertainment systems (DVD/Games), to telematics systems such as GMs Onstar not to mention the control subsystems. Software now accounts for 35% of a cars value, and this percentage is only going to get larger. The theory behind this is that the mechanical systems of automobiles are now essentially a commodity, and the real product differentiation occurs in the software systems. Many cars are equipped with full blown 32bit real-time memory protected operating systems such as QNX.
