This use of bypass diodes allows a series (called a string) of connected cells or panels to continue supplying power at a reduced voltage rather than no power at all. Bypass diodes are connected in reverse bias between a solar cells (or panel) positive and negative output terminals and has no effect on its output. Ideally there would be one by

Ebike uses less carbon than cycling

One such activity is traveling one mile by an electric bike. Who would have thought that a mile on electric bike is 20 times more carbon friendly than a mile on a conventional machine? How is that possible? Apparently it is because feeding the rider of a conventional bike is far less carbon efficient than recharging an ebikes' battery. In addition, electric motors are around four times more efficient than human legs in converting chemical energy into power. In fact, Berners-Lee calculates if all the recharge energy came from solar power, the "electric bike would beat the conventional bike by a factor of 1000." Wow! https://www.linkedin.com/pulse/electric-bike-emissions-truly-amazing-john-waters https://youtu.be/_-FgxTxBtU0

Speed of Solar powered vehicles

EV can travel at 20 km/h at peak sunlight. This is a fast cycling speed. It will only be one quarter sunlight that EV will drop to 5 km/h, at fast walking speed. It may look so slow but at city centres or streets, these are the normal speeds. Are they really possible? I was inspired by the low electric consumption of a converted Land Rover, who uses up only 1% of battery capacity going off-road across two mountains, whereas a diesel off-road SUV uses up one quarter tank. The Tesla motor used in the conversion allowed a Tesla Model 3 car to consume 120 Wh/km at an urban cycle that includes highway driving. At slow speeds, only rolling resistance remains so it can drop to 50 Wh/km. A Lightyear One Solar Car averages 80 Wh/km but it uses full hub motors and no gears. It's aerodynamic drag is only slightly better than Model 3 so its slow speed consumption should be around 40 Wh/km, better than a Tesla car, but should not exceed 80 Wh/km. The measurements for a Tesla Roadster indicated

Ebikes more fun and efficient than pedal bikes

Study finds electric bikes are 21% more fun and 13% more efficient than pedal bikes Micah Toll  | Nov 16 2022 - 10:54 am PT 41 Comments Electric bikes, which provide motor assistance to make pedaling easier, have seen surging popularity over the past decade as a fun and efficient alternative form of transportation. One of the biggest successes of the  e-bike movement  has been creating new riders out of drivers that wouldn’t have otherwise considered switching from a car to a pedal bike. Now, a new study is showing just how much more efficient (and fun) e-bikes are than pedal bikes. The study, titled “ It’s electric! Measuring energy expenditure and perceptual differences between bicycles and electric-assist bicycles ,” was published in the latest issue of the  Journal of Transport & Health. The researchers compared pedal bikes to electric assist bikes from a bike share program with one-hour rides on each bike, finding that e-bike riders used 13% less energy than pedal bike riders

EV vs Diesel Offroad

Dia boleh convert apa apa kereta kepada elektrik. Bukan saja senyap, kuat effortlessly, luas tapi sangat jimat kalau perlahan. Boleh order dari dia di UK. Kita boleh pasang di sini tapi mungkin perlu beberapa perubahan yang memerlukan precision engineering yang kita tiada. I am designing my Transparent SUV with maximum Offroad capability. I notice that road clearance will make it even easier and comfortable to drive Offroad. Cybertruck has ground clearance of 16 inches but I do not know how it achieved this so I tried to surpass this specification. I am able to get clearance of 18 inches, or 0.7m using 0.6m tyre diameters. This is 28 inches. Now, there is no need to use air bags to raise the wheels. We can even raise the wheels selectively. What stopped me earlier was the availability of air bags that can give this ground clearance. We can even do without any air bag, just springs. Airbags are useful for comfort only, no longer a necessity to have a tilting solar powered car or extreme

MirrorLink vs. Android Auto vs. Apple CarPlay

https://www.makeuseof.com/mirrorlink-vs-android-auto-vs-apple-carplay/ MirrorLink vs. Android Auto vs. Apple CarPlay BY JOWI MORALES PUBLISHED JUN 17, 2022 Whether buying a new or second-hand car, you'll want to find out how to connect your device. It could make all the difference! Readers like you help support MUO. When you make a purchase using links on our site, we may earn an affiliate commission.  Read More. Drivers are rightly discouraged from using their phones while on the wheel. But given how much our lives are intertwined with mobile technology, it's increasingly becoming impractical not to use our smartphones for in-car navigation, music, and communication. So, to help drivers use their smartphones safely, you can now pair your smartphone to your car's infotainment system. And while having something like this isn't the first thing car buyers look for, it's become an essential feature drivers want in a new car. Today, we'll look at the three most popul
