Fortescue Metal Group's Infinity train will never need to be fuelled, never need to be charged... it uses regenerative braking to charge onboard batteries when it goes downhill and uses that charge to get back up the hill. Does that sound like a perpetual motion machine to you? The project doesn't actually rely on a secret source of "free energy" to work. Sorry if that disappoints you! It's all based on sound physics, which I explain in this video and then I run the calculations to see whether the numbers add up! Calcs from David Cebon, Professor of Mechanical Engineering at Cambridge University can be found here! https://textdoc.co/2Aztp3Y8KQH5Puhb Bookmarks: 00:00 Intro 01:34 What is Fortescue's Infinity Train? 03:03 THe physics behind the Infinity Train 05:53 Calculations 09:35 e-Dumper: Kuhn Schweiz AG's electric mining truck 11:34 Rosie's thoughts on regenerative braking technologies 11:43 Thanks to Brilliant for sponsoring this video! 12:41 Outro Sources: Craft4 Shubham - 100% working free energy https://www.youtube.com/watch?v=YWaAhdC86mk Veritasium - Risking My Life To Settle A Physics Debate https://www.youtube.com/watch?v=jyQwgBAaBag Fortescue Metals Group - Fortescue Williams (WAE) settlement powers development of world's first Infinity Train https://www.fmgl.com.au/in-the-news/media-releases/2022/03/01/fortescue-williams-(wae)-settlement-powers-development-of-world-first-infinity-train Tom Scott - The UK's last aerial ropeway uses no power, moves 300 tonnes a day, and will be gone by 2036. https://www.youtube.com/watch?v=6RiYXI1Tfu4 UN Climate Technology Centre & Network - Regenerative braking in trains https://www.ctc-n.org/technologies/regenerative-braking-trains Fortescue Metals Group - Climate Change Report FY21 https://www.fmgl.com.au/docs/default-source/announcements/fy21-climate-change-report.pdf?sfvrsn=b26e27f9_4 Ogawa et al, 2017 - Method of Calculating Running Resistance by the Use of the Train Data Collection Device https://www.jstage.jst.go.jp/article/rtriqr/58/1/58_21/_pdf/-char/ja Lucas di Grassi - eDumper - The BIGGEST EV in the world! https://www.youtube.com/watch?v=7ikxdFeOQZE Jalopnik - These Electric Trains Never Need Recharging Thanks to Regenerative Braking https://jalopnik.com/these-electric-trains-never-need-recharging-thanks-to-r-1848975204 If you would like to help develop the Engineering with Rosie channel, you could consider joining the Patreon community, where there is a chat community (and Patreon-only Discord server) about topics covered in the videos and suggestions for future videos and production quality improvements. https://www.patreon.com/engineeringwithrosie This video was sponsored by Brilliant.
