The "Varyflush" water-saving device for toilets, the fully ergonomic keyboard, the under water bike and the talking potty are just some of the exhibits on display at the British Invention Show.
But how many will make it into our homes? Not enough, according to some of the world's most eminent inventors. Britain, once the cradle of inventions such as the printing press, the steam engine, electricity and the telephone, has turned its back on product innovation.
That's why inventor and businessman Paul Davidson has set up Facilities Corporate Management (FCM), a business accelerator fund to help inventors commercialize their ideas.
Davidson, who created the Oyster Converter -- a fitting that allows pipes to be joined without welding, soldering or compression -- knows all about the frustrations of an inventor.
"Inventors are treated with total disdain by business in this country, and yet they're some of the richest people in the world," he said in a telephone interview.
Davidson's innovative pipe-fitting was rejected by engineering firm Delta Plc. So he set up his own firm, Oystertec, which was so successful that in October it bought Delta's plumbing unit for ?28 million (US$40 million). But his case is the exception to the rule.
"I've heard estimates that Britain has lost as much as ?165 billion from inventions made here but exploited abroad," said Trevor Bayliss, inventor of the wind-up radio.
The hovercraft, the vertical take-off plane and CAT scanners are just a few British inventions lost to foreign manufacturers.
James Dyson, who invented the bag-less vacuum cleaner, blamed a smorgasbord of economic and cultural reasons for the decline of entrepreneurial spirit in Britain.
High interest rates, a strong pound, and a financial system obsessed by short-term returns have halved the country's manufacturing base since World War II. As most inventions are products that have to be made, this has devastated the market.
Dyson, who spent two fruitless years trying to sell his vacuum cleaners in Europe before being granted a licence in Japan within weeks, said Britain's education system was biased against practical disciplines such as engineering.
"It's a whole way of thinking we have lost," he said.
Sharing these concerns, Bayliss has set up the British Academy of Invention to provide advice, help and a forum for inventors to discuss ideas.
Davidson is also doing his bit for the industry. FCM is sponsored this month's British Invention Show in London. But he also sees a business opportunity.
"The mistake the government makes is to try to turn an inventor into a businessman," he said, referring to various schemes that provide small grants to set up enterprises.
AIR SUPPORT: The Ministry of National Defense thanked the US for the delivery, adding that it was an indicator of the White House’s commitment to the Taiwan Relations Act Deputy Minister of National Defense Po Horng-huei (柏鴻輝) and Representative to the US Alexander Yui on Friday attended a delivery ceremony for the first of Taiwan’s long-awaited 66 F-16C/D Block 70 jets at a Lockheed Martin Corp factory in Greenville, South Carolina. “We are so proud to be the global home of the F-16 and to support Taiwan’s air defense capabilities,” US Representative William Timmons wrote on X, alongside a photograph of Taiwanese and US officials at the event. The F-16C/D Block 70 jets Taiwan ordered have the same capabilities as aircraft that had been upgraded to F-16Vs. The batch of Lockheed Martin
GRIDLOCK: The National Fire Agency’s Special Search and Rescue team is on standby to travel to the countries to help out with the rescue effort A powerful earthquake rocked Myanmar and neighboring Thailand yesterday, killing at least three people in Bangkok and burying dozens when a high-rise building under construction collapsed. Footage shared on social media from Myanmar’s second-largest city showed widespread destruction, raising fears that many were trapped under the rubble or killed. The magnitude 7.7 earthquake, with an epicenter near Mandalay in Myanmar, struck at midday and was followed by a strong magnitude 6.4 aftershock. The extent of death, injury and destruction — especially in Myanmar, which is embroiled in a civil war and where information is tightly controlled at the best of times —
China's military today said it began joint army, navy and rocket force exercises around Taiwan to "serve as a stern warning and powerful deterrent against Taiwanese independence," calling President William Lai (賴清德) a "parasite." The exercises come after Lai called Beijing a "foreign hostile force" last month. More than 10 Chinese military ships approached close to Taiwan's 24 nautical mile (44.4km) contiguous zone this morning and Taiwan sent its own warships to respond, two senior Taiwanese officials said. Taiwan has not yet detected any live fire by the Chinese military so far, one of the officials said. The drills took place after US Secretary
THUGGISH BEHAVIOR: Encouraging people to report independence supporters is another intimidation tactic that threatens cross-strait peace, the state department said China setting up an online system for reporting “Taiwanese independence” advocates is an “irresponsible and reprehensible” act, a US government spokesperson said on Friday. “China’s call for private individuals to report on alleged ‘persecution or suppression’ by supposed ‘Taiwan independence henchmen and accomplices’ is irresponsible and reprehensible,” an unnamed US Department of State spokesperson told the Central News Agency in an e-mail. The move is part of Beijing’s “intimidation campaign” against Taiwan and its supporters, and is “threatening free speech around the world, destabilizing the Indo-Pacific region, and deliberately eroding the cross-strait status quo,” the spokesperson said. The Chinese Communist Party’s “threats
