Endless Sphere

I didn't watch the video. Autonomous vehicles will predominate as soon as they cost 10X less than what we're doing now. A major portion of that 10X will be not having to own the motive part. It follows that 3rd parties will own and maintain/operate-for-hire the motive part, so that will make it chea...

Its a useful place for discretionary material, and more useful than fun.

I don't remember anything like that is it from the 50's?

Here's a video about the tether-boat history where they made their own engines & boats in the 30's & 40's.

I had no idea about any of these tether hobbies. Seems fun enough.

Progress ends ICE. Solar+battery+autonomous = 10X cheaper transportation. As soon as that happens it will be a steep adoption curve. We'll be half done converting to service-on-demand autonomous in 5 years and completely done by 2030. Most of what trucks do now will be done by smaller autonomous veh...

Beautiful. Looks like you retained the stock motor sprocket location and replicated the stiffness of the original gearbox to maintain original chassis engineering. Seems like the CG is probably the same, too.

I wonder if wax would dampen the chain sound without being messy?

If its the battery low-voltage circuit cutting power, you might only need more or bigger batteries. Does it torque stall more easily as the batteries get lower?

If you never discharge past half capacity and recharge immediately after any use (not 'a few hours later'), lead can work. A good example would be a lawn mower that gets plugged in anytime its not being used.

The +\- terminals on the ego battery bypass any electronics, and are connected straight to the cell string. The tools decide when to stop accepting battery power. Any BMS is only for the charging/charge display.

This is from the parts diagram from a dual battery EGO snowblower and mower. You can see what looks like capacitors on both the expensive items, so I assume those are the controllers. I'm guessing the $80 & $117 items are diodes and/or power mosfets for switching batteries off. ego_harness.jpg e...

The My2018 has heat limitations and will waste lots of electrons once its getting thermally stressed.

Since when did a RICKSHAW suddenly become a Pedicab ? ..Rickshaw, also spelled ricksha, also called jinrikisha or jinrickshaw, (from Japanese: “human-powered vehicle”), two-wheeled vehicle with a doorless, chairlike body and a collapsible hood, which holds one or two passengers and is drawn by a ma...

Personally, I would keep it in the USA bicycle category for speed. Too much regulation otherwise. Nobody cares if you're using more than allowed power to get up hills, speed is the main focus of the authorities. Going forward since CV, isolation will have a much higher value. Public transport is doo...

Could stretch electric rickshaws be a useful tool for transporting people? Chalo?

The CCP is going down soon and its going to be messy.

Vehicle insurance will be as dead as ICE's when they dissappear from roads, with half gone within 5 years. The more pertanent question will be how 2-wheelers in general will coexist with autonomous vehicles. Will society chose to fund roads for anything but autonomous vehicles?

…You make a balsa frame (grows naturally down here, a junk wood often used to make pallets). … You can stiffen up balsa with the thin cyanoacrylate (superglue) that model airplane makers use. Makes balsa strong and hard, but also more brittle. I made a 2" X 2" footlong 'bridge' using 1/16...

https://en.m.wikipedia.org/wiki/Alternating_current

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.

Ebikes have DC motors that are electronically commutated through 3 successive phases.

One reason is that you can size your motor/controller/battery to the peak load and then run them at partial load without a significant efficiency hit.

Controllers and batteries are advanced enough now that transmissions aren't part of the path forward.

Starting your car just to maintain your battery seems unwise, expecially if the car doesn't get fully warmed up. Modern cars' computers draw enough current to justify a maintainer charger if you aren't using the car daily. If you can't plug in, attach a 'booster' battery that you can easily bring in...

I would think an important distinction would be whether you are engaged in commerce. Governments like to regulate and tax commerce.

Can you post pictures? Some closeups might be nice.

There are moped hubs that have a freewheel on one side, sprocket on the other, and a drum brake in the middle.

Like all Teslas, the Cybertruck's motors are backed by a one-speed automatic.
