Re: Persecuting E-Bikes in New York City

Nah - that doesn't work either. I can change my bike to Class 1, 2 or 3 by changing a few options using the LCD panel. So you configure your bike for the desired class, get it registered, slap on a sticker, and then reconfigure it. Suddenly enforcement isn't so easy. If it is reconfigurable, it's n...

Re: Persecuting E-Bikes in New York City

Actually, they cannot. Class 2 does not say there is no throttle. Right; it says there generally IS a throttle, but it can also have a PAS. From the class listings at Electric Bike Review: Class 1: Pedal Assist The electric drive system on the ebike can only be activated through a pedaling action a...

Re: Persecuting E-Bikes in New York City

Well then sanction the wreckless rider. It`s not doing 35 mph because it's got a throttle. It's doing it cause the guy is wreckless riding on sidewalks with an overpowered 1500W and up eBike kit. Once again, THE THROTTLE HAS NOTHING TO DO WITH THE SPEED !!!! Most overpowered bikes use throttles; th...

bms with adjustable top and bottom cutoff

I'm looking to have a 4s pack of EV batteries for a power wheels car. I'd like to not exceed 4.1v and keep the cutoff to around 3.0v OK a few misconceptions here. A BMS cuts off voltage if cell/pack voltages exceed the safe range. It does NOT terminate charge, nor is it set to the same levels. It i...

Re: Around the world on a solar ebike

Fast forward to today and we have "active diode" or "smart diode" devices like this Texas Instruments SM74611. It's not small enough to encapsulate within the cell but the cost ($3-4), forward voltage (26 mV) and reverse leakage current (3 µA) make it feasible to put one for every 4 or 8 cells. Not...

Everyone knows that wind turbine manufacture is responsible for the vast majority of radioactive sludge lakes, some as big as 10km2 in size. Only gullible types who fall for right wing propaganda.

What i said was they wont last 50+ years. And I demonstrated that you were wrong. And further, they will undoubtedly be replaced with newer technology before they get near that age. Perhaps.

My custom-made PV modules arrived last week. Here's a quick peek at what they look like.
Cool panels.

Can I ask why you chose those over a more standard 4x6 panel like the Solbian SP78? Was it the extra few watts you could get, or was there some other benefit in going completely custom?

Re: Around the world on a solar ebike

I wonder if there is a way to build simple and small reflective mylar panel(s) to redirect some light from the outside of the panel onto the area with the shadow to compensate for the power loss when the shadow is present? Probably not. 1) You'd have to replace the illumination, which means 2x mirr...

Re: Regenerative Braking, is it this easy!?

I think it's more that with conventional rim/disc brakes, the torque from the wheel is applied to the frame (where the brakes are mounted), so the axel sees limited stress from braking. Right. Torque can only be applied _between_ two places (for example, a car's driveshaft and its motor/transmissio...

But there are also many coal fired generators that have remained in service for over 50 yrs, and several more that will pass that also.
Nuclear plants have a design life of 50 yrs and many surpass that also.
Not without major overhauls and upgrades.

About the torque, isn’t it the same amount and direction of torque being applied as when I brake physically? Meaning if my brakes work fine and my wheel hasn’t fallen off yet (steel frame, old but not a cheapo) I should be good? Nope. The torque from conventional brakes is applied to the rim; this ...

Obviously the idea that a solar farm could function for 30-50 years without major rebuilds and upgrades , is laughable... A recent NREL study looked at solar farms that are 30-40 years old. Panel degradation averaged .7% per year for all panels. But when limited to crystalline panels in long term (...
