On the morning of March 5, local time, one of Britain’s greatest inventors, Trevor Bayliss, died of illness at his home in Twickenham, southwest London. He was 80 years old. His wind-up radio has benefited millions of people in poor areas around the world.
In 1992, while watching a TV documentary, Bellis, who was already over 50 years old, learned that AIDS was widely spread in Africa, but due to the lack of local electricity, African people were unable to use any communication equipment. , for prevention and treatment information. So he invented a new type of radio that was powered by a clockwork dynamo that produced enough electricity to operate the radio without the need for a power source.
In the same year, Bellis established a company in Cape Town, South Africa, to produce wind-up radios. In addition to Africa, other less developed countries and regions also have high electricity prices or no electricity, so wind-up radios became very popular as soon as they came out. Millions of people in poor areas have access to the latest information and are better educated.
Bellish is known for fighting for the rights of inventors and protecting intellectual property rights, and he has long called for the theft of other people's ideas to be made a criminal offence. However, in 2013, the company that produced the wind-up radio changed the original design and reapplied for a patent. Due to a loophole in patent law, Bellis lost control of his wind-up radio and he went bankrupt.
Belish never married and had no children or other living relatives. During his lifetime, he invented more than 250 products, including wind-up flashlights, cell phone chargers and MP3 players. In March 2015, Bellis was awarded the Order of the British Empire.
