About

This channel seeks to understand the issues that face our civilisation in the 21st Century and focusses on the potential solutions that will save as many lives as possible and hopefully bring about a greater level of equality in the world. The channel is not a debating forum about whether Human Induced Climate Change is a real phenomenon or not. If that's what you're after then I can highly recommend chat forums on Social Media, where people on both sides of the argument go round and round in circles achieving precisely nothing at all. That is a mug's game. And it's not my game. Anyway, outside of those caveats, I do try to keep it light and humorous wherever possible, so I hope you enjoy the content. Oh..and me... Dave Borlace. Born 1969. BSc in Technology from the Open University in the UK. After a 30 year career in People and Project Management, I now work full time on the channel thanks to the amazing folks who support me on Patreon at patreon.com/justhaveathink

Video Description

Ultra-High Voltage Direct Current (UHVDC) electricity transmission ought to be the stuff of pure science fiction. More than a million volts carrying the equivalent of 12 large power stations worth of power down a single line? Such a feat should be unthinkable. But it's here right now. Today. And since it's installation 3 years ago, it has delivered more than 300 BILLION kilowatt hours of electricity from wind and solar farms in the North West of China to the industrial centres 3000km away in the East. Now China is building another 2700km UHVDC line from the Tibetan plateau to the Guangdong - Hong Kong -Macau region. And it's planning another 10 lines by 2050. So can the West ever hope to compete with such ambition?
