colly0410 1,181 Posted October 22, 2019 Report Share Posted October 22, 2019 If all cars/vans go electric where will all the extra electricity to charge their batteries come from? They'll have to build more power stations.. 1 Quote Link to post Share on other sites
colly0410 1,181 Posted December 8, 2019 Report Share Posted December 8, 2019 On hols here in Tenerife & noticed taxis have blue number plates at the back & white at the front, can't remember seeing this last time I was here in 2007 or in Gran Canaria last year. Wonder if only here or all over Spain/ Quote Link to post Share on other sites
MargieH 7,599 Posted December 8, 2019 Report Share Posted December 8, 2019 @colly0410 I'm sure I heard someone say that the batteries are/will be made to charge when the brake is used. I know nothing about cars but this sounded like an interesting concept to me.. Quote Link to post Share on other sites
philmayfield 6,115 Posted December 8, 2019 Report Share Posted December 8, 2019 It's called regenerative braking Margie. Rather than explain it in detail I suggest you look it up 'cause it's a lengthy topic. Quote Link to post Share on other sites
Stuart.C 491 Posted December 8, 2019 Report Share Posted December 8, 2019 And regenerative only adds a small bit to the battery. Quote Link to post Share on other sites
philmayfield 6,115 Posted December 8, 2019 Report Share Posted December 8, 2019 Yes, sadly the perpetual motion machine is yet to be invented! Quote Link to post Share on other sites
Ayupmeducks 1,730 Posted December 8, 2019 Report Share Posted December 8, 2019 I forget what country it was, but regen battery charging was used on one of their cities buses. The buses had a heavy flywheel that assisted in "storing" (kinetic) energy as well, from recollection it was a partial success, as the bus stopped, a clutch disconnected the motor and the flywheel kept a small generator running charging the batteries. Bit cumbersome, but at least someone was trying. As far as perpetual motion is concerned, I think you will find it is possible. I saw a video of a feller who had a motor generator set where initial energy was used to start the motor, which was then fed by the generator. He'd worked out how to gain more energy out than used in generation. I know, but all the laws of physics are theories and theories change when proven ones are dismissed. He couldn't get anyone to look into his test set up, found an Indian electrical engineer at an Indian nuclear power station to look into it and explain WHY it worked. The engineer looks at a schematic he'd enclosed and said IMPOSSIBLE. After some pleas, he built a test set up according to the engineering drawings and put it to the test and was floored! He stated, I have no explanation as to "how" it works, BUT it does! It defies all the known laws of physics... I doubt we will hear too much of it as it presents a danger to commercial annual profits. Quote Link to post Share on other sites
philmayfield 6,115 Posted December 8, 2019 Report Share Posted December 8, 2019 Coefficient of friction of the moving parts will prevent full perpetual motion. Also gravitational force will act against it. Quote Link to post Share on other sites

Ayupmeducks 1,730 Posted December 9, 2019 Report Share Posted December 9, 2019 The most brilliant minds ever, never had university educations that moulded them into their way of thinking, two come to mind, Einstein and Tesla, when it comes to engineering and science NEVER scoff at any idea. We were taught "laws of physics" according to our discipline, mine being electricity and electronics, my mind was moulded to fit their teachings, including text books, learn to think outside the "box" and ANYTHING is possible. Had the inventors of many things thought it was like two unicorns, we'd still be in the dark ages. "Iron ships", heavier than air flight, flat screen monitors, semi conductors, chips holding millions of transistors" etc being perfect examples of what I said. Quote Link to post Share on other sites

philmayfield 6,115 Posted December 9, 2019 Report Share Posted December 9, 2019 Laws of science can proven by demonstration. Theories, such as those of Einstein and Darwin are not wholly proven but no one has yet come up with a better premise. Quote Link to post Share on other sites

Ayupmeducks 1,730 Posted January 20, 2020 Report Share Posted January 20, 2020 When I worked at Boulby Mine, I arrived at work one afternoon shift and there was an RR parked in the employees car park, I thought Jeeze someone puts a lot of overtime in to buy one of those. Turns out it belonged to one of the Surveyors, no they didn't pay that well, he used to buy RR's that were insurance write offs and restore them. Quote Link to post Share on other sites
