Re: Building The World's Largest Thermal Solar Plant

Emerging solar plants scorch birds in mid-air IVANPAH DRY LAKE, Calif. — Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant's concentrated sun rays -- "streamers," for the smoke plume that comes from birds that ignite in midair....

Re: Aug 19th: e-Bike World Record Attempt Sendoff in Missoul

Re: Pusher electric trailer.

I bought a BOB IBEX for just that idea. Before attempting any mods, I gave it a trial run – hauling a load of groceries from my local… and I was not impressed. Never used it again; it remains stored in the back room. :( Decided to built my own trailer using a “jumper” frame . It had some issues that...

Although they did not speak about industrial battery capacity per se,
that is the first time I've heard someone claim we're over 25% peak in renewables in certain regions - and growing.

Re: SPICE: Defining Components

Re: EB218 18FET regen stutter

I am thinking that you are literally up against the wall: Using a 100V controller with a 24S battery which at full charge (4.2V * 24) = 100.8 VDC. When you try to ebrake/regen – there simply is not enough headroom to make a braking effect. I use a 100V-rated controller, though run with a 15S battery...

Re: EB218 18FET regen stutter

Without knowing small details, it’s a guess. The times I’ve had stuttering performance was where the insulation frayed against the framework and was shorting in damp weather, or I had a flakey ebrake switch; check the ebrake signal line for continuity. Check the ebrake switch to be sure it is perfor...
