Cords and wires are likely to disappear from our homes after 2015.Extremely efficient batteries will provide cable-free operation of many household devices, including vacuum cleaners, computers and irons. For this reason plug sockets will be replaced by battery re-charging stations. Most of the electricity required in such wireless power networks will be generated by conventional technology, although advanced solar panels, wind and wave power generators will become quite common. Some high-tech homes will use other alternative energy sources.
Movable walls made of lightweight sound-proof materials will allow us to section off another bedroom for a visitor or create a large single space to host a party in just halt an hour. Other walls will function as huge screen displays. Still more flexibility will be achieved multi-purpose furniture. At our request it will change structure and shape, or even the colour and texture of the covering.
By 2050 computers will be almost in complete control of our homes. Small and cheap, they will sense changes outside and inside and adjust light, temperature and humidity levels automatically. They will check efficient use of energy for heating and cooling and operate numerous electro-mechanical devices, e.g. they will immediately detect litter dropped oh the floor and send a robot vacuum cleaner to clean it up.
