For the majority of people hovercraft are a new experience. Our knowledge of them is usually gleaned from newspapers, television, magazines and the like, and consequently misconceptions are ripe.
For any vehicle to operate economically the drag, or resistance to motion, must be kept to a minimum. The majority of drag arises from the motion of the vessels hull through the water, therefore we can reduce drag and consequentially propulsive power by minimizing hull contact. The hovercraft achieves this by using low-pressure air to form an air cushion beneath it, thus actually lifting the hull clear of the water/ surface. In addition, by using air propulsion to generate forward movement, the hovercraft becomes amphibious, and able to traverse land, soft terrain / mud flats or water. The main point here is that because the hovercraft does not pierce the surface over which it is traveling the advantage is two-fold,
a) less friction = less fuel burnt to move,
b) less friction or interruption to the surface = less disturbance of the environment.
Therefore Hovercraft can be used to best advantage in shallow water and drying areas, these areas often being remote and environmentally sensitive. Most of these areas are wetlands, swamps, and river delta. They are not only the feeding ground for a lot of different species of birds but as well very often used from marine live for hiding from predators. In these sensitive areas are nearly no transportation means available. Hovercraft are able to operate in these areas in an environmentally friendly way.

the hovercraft was invented by using alot of parts
The power source of a hovercraft is generally a battery system with an electric motor or a gas engine. The hovercraft is lifted using a large fan.
Hovercraft is remarkable technology, expanding transit options in unpredictable terrain, as below. The performance of Hovercraft in this extreme environment means that for any predictable period of uptime, you'd be required to carry a Hovercraft mechanic and spare parts with you as you travel. Known performance in Antarctica is not reliable enough to permit unsupported transit using this technology.
The advantages of desalination is that you are not going to run out of water if you are using a water source like the ocean.
what are the advantages and disadvantages of refrigeration

Compact Refrigerators save space because of their smaller form, this in turn means they are easier to store when not in use and transport if using in a camping environment.

what are the disadvantages of land transport?Disadvantages: Land transport is slower.Destinations are more limited.Runs on more fuel, if using a land vehicle.Advantages: Land transport is safer than sea transport.

their can be a leakage in the pipelines. It can be broken the thing can be transported easily and conveniently. It is profitable
The advantages of using paper would be having a hard copy, being able to easily transport it. The disadvantages would be more trees cut down. More likely to become wasteful.
This depends on what means of transport you are using to get there.
less likely to aggravate existing injuries
a hovercraft can go upto 60 mph
A "maglev" or "magnetic levitation" train is suspended over the magnetically polarized rail. A hovercraft is more like a low-flying helicopter, using fans to blow air down underneath the vehicle. A hovercraft is sometimes known as a "ground effect vehicle", because it compresses air between the ground and the hovercraft. Hovercraft do not require tracks, and are equally able to "fly" over land and water.
The advantages of using a cordless home phone is that one can move around whilst using it. This means that one can have a conversation in any part of the house.
