        Have you ever dreamed of building your own time machine? Do you wish you could invent something new? You can find many inventors in British culture, although some of their designs have been more successful than others. Here we look at a few.

        The Sinclair C5

        The C5 was a simple vehicle which moved at 24 kilometres per hour and had three wheels. You didnt even need to have a driving licence to use it. The C5 was invented by Sir Clive Sinclair in 1985. He spent millions of pounds developing this product and even encouraged Stirling Moss, winner of sixteen F1 Grand Prix motor races, to advertise the vehicle. Unfortunately it had many problems. It did not work well on hills and the battery was easily damaged by rain. It also wasnt very safe. The C5 was so tiny it was difficult for much larger vehicles to see it. Only 12,000 were ever sold and Sinclair lost a lot of money. This didnt stop his enthusiasm for inventing and in 2006 he started selling the ‘A-bike, a lightweight folding bicycle.

        Adaptable glasses

        Do you wear glasses? If so, can you imagine life without them? In 1985 Joshua Silver was a professor at the University of Oxford. One day, a conversation with a colleague about lenses for glasses gave him an idea. He thought, ‘Can I design a pair of glasses that could be changed by the wearer? In places like Africa there are often no opticians in small towns and so people cant buy glasses. He designed two plastic lenses that are filled with a special liquid. Using syringes, you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make, and sell in their thousands. Now Joshua is chairman of the Centre for Vision in the Developing World, which aims to give one billion people in the developing world the glasses they need for a better life.

        The wind-up radio

        When you switch on your TV tonight think about all those people without electricity. Trevor Baylis was thinking about this in 1989 when he came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver, he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who dont have electricity and cannot afford batteries, to use it. The radio has a generator which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Product and Best Design. Baylis often stays awake all night working. He has also designed a range of inventions to help disabled people. All this from a man who started his working life as a stunt man!

        The Dyson cleaner

        In many homes around the world you can see a vacuum cleaner that looks like a spaceship. This is the Dyson vacuum cleaner which uses something called ‘cyclonic separation to separate the dirt. This means that you dont need a bag for your cleaner and it doesnt get blocked, so its very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and he made over 5,000 prototypes before he got it right. He tried to sell his invention to manufacturing companies but they werent interested, so in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and the US, and Dyson himself is believed to have earned over a billion pounds.

        So keep dreaming and inventing, and one day you might get it right!

        Word(s) of the week
