Whatsapp Facebook Twitter The idea for a proposed transatlantic tunnel connecting London and New York has surfaced yet again. However, experts say it is impractical given its eye-watering price tag of $20 trillion and the fact that it could take hundreds of years to complete First, let’s examine the concept of the tunnel itself. Advertisement As per Newsweek, the transatlantic tunnel would connect New York in the United States and London in the United Kingdom. The distance between the two cities is nearly 4,900 kilometres – and flights take around eight hours. It is estimated that construction on the proposed tunnel could a very long time. For example, the 37 kilometre tunnel Channel Tunnel between England and France took a little over half a decade. News week extrapolated that taking the same time, construction on the transatlantic tunnel would take around 780 years. A flight from New York to London takes around eight hours. Reuters The tunnel would also command a hefty price tag – around $20 trillion. All this sounds wildly impractical. However, the difference now is that the concept could become potentially more viable thanks to vacuum tube technology. This concept, which would create a vacuum in the tunnel and use pressurised vehicles, could theoretically send trains between New York and London at a speed of around 4,800 kmph. Editor’s Picks
