583: 788:, which have the advantages of being responsive, useful in a wide range of power levels, environmentally friendly, efficient, simple to install, and easy to maintain. Batteries also facilitate the use of electric motors, which have their own advantages. On the other hand, batteries have low energy densities, short service life, poor performance at extreme temperatures, long charging times, and difficulties with disposal (although they can usually be recycled). Like fuel, batteries store chemical energy and can cause burns and poisoning in event of an accident. Batteries also lose effectiveness with time. The issue of charge time can be resolved by swapping discharged batteries with charged ones; however, this incurs additional hardware costs and may be impractical for larger batteries. Moreover, there must be standard batteries for 61: 713: 34: 87: 599: 10907: 1274: 10931: 10847: 1689: 10782: 7122: 114: 10979: 10871: 7146: 10967: 10835: 10806: 7134: 927: 10883: 1503: 10955: 10919: 10794: 1065:. Electric motors can be very efficient: over 90% efficiency is common. Electric motors can also be built to be powerful, reliable, low-maintenance and of any size. Electric motors can deliver a range of speeds and torques without necessarily using a gearbox (although it may be more economical to use one). Electric motors are limited in their use chiefly by the difficulty of supplying electricity. 10895: 10943: 1485:. Because U.S. aircraft must be flown for some time before they are certified, there is a provision for an experimental airworthiness certificate. FAA experimental aircraft are restricted in operation, including no overflights of populated areas, in busy airspace, or with unessential passengers. Materials and parts used in FAA certified aircraft must meet the criteria set forth by the 10859: 1289:. But it is often required to stop a vehicle faster than by friction alone, so almost all vehicles are equipped with a braking system. Wheeled vehicles are typically equipped with friction brakes, which use the friction between brake pads (stators) and brake rotors to slow the vehicle. Many airplanes have high-performance versions of the same system in their 1577:

Similarly, toll routes are open to the public after paying a toll. These routes and the land they rest on may be government-owned, privately owned or a combination of both. Some routes are privately owned but grant access to the public. These routes often have a warning sign stating that the government does not maintain them. An example of this are

955:. An example of this is the steam engine. Aside from fuel, steam engines also need water, making them impractical for some purposes. Steam engines also need time to warm up, whereas IC engines can usually run right after being started, although this may not be recommended in cold conditions. Steam engines burning coal release 1637:

There are specific real-estate arrangements made to allow vehicles to travel from one place to another. The most common arrangements are public highways, where appropriately licensed vehicles can navigate without hindrance. These highways are on public land and are maintained by the government.

Compressed gas motors have been used on some vehicles experimentally. They are simple, efficient, safe, cheap, reliable and operate in a variety of conditions. One of the difficulties met when using gas motors is the cooling effect of expanding gas. These engines are limited by how quickly they

Passenger aircraft carry a great deal of safety equipment, including inflatable slides, rafts, oxygen masks, oxygen tanks, life jackets, satellite beacons and first aid kits. Some equipment, such as life jackets has led to debate regarding their usefulness. In the case of
