Wireless devices are a great achievement. They are handy and lightweight. Some of them are essential to our freedom. Technologically poor countries develop fast thanks to CB radio, satellite phones, television broadcast and solar panels. The need to invent new techniques for wireless devices allows for further improvements of classic devices. For example : today home computers use ten up to hundred times too much transistors, memory locations and electric current in regard to their actual performances and reliability. Lightweight processors like the ARM and new operating systems such as Linux for handheld computers will allow to build massive parallel computers that will be a lot more powerful... using the same amount of transistors. Wireless devices will improve even further. One day they will use little power cells that consume the oxygen from the air and fuel from a little reservoir, maybe driven by bacteria. They will deliver five times more power than today batteries, will be more secure and perhaps simply reloadable with table oil or sugar. One closer improvement for wireless devices can be the use of directive low-power laser or microwave beams. Today devices broadcast their signal in all directions. This is a waste of energy and a source of environmental and bandwidth pollution. This is even dangerous to your health. But directive devices, like phase shift microwave antennas or laser emitters and receivers mounted on mobile beds are a good solution. They allow to use a minimum of transmission energy and avoid disturbing other communicating devices. Little public relays placed on ceilings and roofs will allow distant devices to communicate without even using central signal routing servers.
But I do not understand why people praise wireless devices because, so they say, the problem with wires is they mess up. My wires do not mess up. Wires are a low-cost, highly efficient, reliable and non-polluting way to transmit energy and information. If we want every people on this planet to be able to buy communication devices and electric appliances, we will have to concentrate on wired devices. The problem with green energy plants (windmills, barrages, solar plants, industrial wood ovens...) is they often fall down because they lack wind, water, sun or wood supply. In order to supply every country with a steady electric power network, a giant electric network - wired - will have to be build across the planet, bringing the electric power to - wired - appliances in every home and industrial plant. That way the fact the power plants of one country fall down will be no problem for that country because it will momentarily buy its current from other countries. This will make governments to cooperate amongst each other and fasten the abolition of frontiers. In order for the wires inside a home no more to mess up and drive the people mad, a few changes will be necessary. First of all, using wires needs some discipline. Most people mess up their wires because they plug and unplug them at random. Wires become twisted, mixed, make loops and knots with other wires or around objects. When I change a wire I unplug it completely, from both sides, I pull it out of the wire pool, I place it back again inside the wire pool and plug it back in. That way I get no twists or knots. Every change is made simple, without any fuss. Secondly, a mechanical problem with most wires is their plugs are virtual hooks and anchors. Whenever you pull on a wire amongst other wires, its plug will catch the other wires, blockade and make things difficult. A good plug should be relatively small and have a convex shape, so it can be slid amongst other cables with no hamper. Third, the problem with cables is they are often too short or too long. Too short, you cannot make the connection. Too long, the cable will make loops that will mess up the cable pool. The loops of a long cable can be latched together, close to one of the plugs. But that's not the best solution since the latched loops become an anchor. Best is perhaps to use short and medium-sized cables simply plugged together to form long cables. Whenever a cable becomes too long, you just unplug one of its sub-cables. Finally, power supply and communication plugs can be placed everywhere inside a home. That way every appliance can be used everywhere, using just short wires.
This last technique is already commonly promoted. As much as possible, at home and outdoors, cables must be burried away.
