Re: Wind and Solar vs Coal, Gasoline, Nuclear

We are more attuned to looking back to see what happened than being aware of it happening at the time. I do see food shortages and instability. See the establishment fighting to maintain the status quo. They started losing their grip 10 years ago, but fighting hard to keep it maybe why trump was el...

Re: How Will Electric Vehicles Be Modified in the Future?

People will. It just won't be power mods. I'm sure there will be a few but it won't be anywhere near what it is today. How could it be, I'd say 90% of the tuning market is exhaust, cams and turbos. All gone. But there are cold gas thrusters. And once Tesla launches the next Roadster, those parts wi...

Re: Question for the Wizzards...why can’t Enphase micro inverters be connected in parallel?

I consider similar configuration. From Ecat/Doc's posts we have below: 1. two M215 with input parallel to PVs, and putput to grid 240VAC, burnt immediately. Outputs I believe is via trunk cable, and input polarity also correct. 2. two M190 with input parallel to a power supply, and output to grid 2...

Re: How Will Electric Vehicles Be Modified in the Future?

However, within the context of the discussion, you're saying if the Raptor was the same price at a base model people would take the base model. Of course not. They'd want the Raptor, everything else being equal. Which is totally incorrect. If people get free floor mats and a tank of gas with their ...

Re: How Will Electric Vehicles Be Modified in the Future?

And the Raptor is the flagship $70K 450hp model. Because that's what everyone wants, a "tuned" F-150. How many customers walk into a Ford dealership and say "I don't want a new Raptor, it won't last with all that fancy hp, give me a base model"? Most of them. Most people do not go to dealerships th...

It's a numbers game. As long as the net is higher than the losses they will offer it. Exactly! And the tradeoffs a company makes in order to make more money will often not be the same as the tradeoffs a driver wants for his vehicle. What's the saying, win on Sunday sell on Monday.

Just FYI - that rack is going to fail quickly. If you can't sit on it with 180ish pounds while it's not moving, it won't stand up to 10-20 pounds while dealing with potholes and curbs.

Well you probably never worked at a car company. Lawsuits and settlements are built into the price of vehicles. Of course. And the way they make money is having FEWER lawsuits and settlements.

Think about it. If you released a remap of a Tesla that was somehow better they would send the remap to every single owner the minute you released it. You don't have proprietary control over their software. (well maybe not the minute. someone would get a memo and then a team of engineers would go o...

It's not like bike motors today, cars are coming with programmable controllers that can do whatever you want them to do. Not easily. And although no one has done this yet (fortunately) it is quite possible to make it impossible to hack vehicle controllers. It doesn't make sense to sell a car with a...

Re: How Will Electric Vehicles Be Modified in the Future?

But you still have to engineer to the peak output which happens at start-up. In an ICE I can limit the top end, limit revs, fuel etc. You can't do that with electrics. Of course you can. You do it in software. When we're talking about things that people want but don't need I would say that's "custo...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

So solar has a different frequency than Natural Gas? I always thought it was the equipment that set it regardless of what was producing it. Yep. It's set inherently by the grid itself - and occasionally by another reference signal. RE providers often provide "ancillary services" which include frequ...

Re: Help me develop the perfect throttle

Not a great Idea, the breakaway moment could be too high. Bad for slow accelleration. Maybe a click sound would be a better sound instead. Gotta have a mechanical detent so that you are: 1) guaranteed rapid return to zero if the throttle is released 2) have a tactile means of knowing when you are a...

Re: DC to DC converter goes tick tick tick

The converter is probably going overvoltage and shutting down. Or is just plain unstable. Shouldn't harm it as long as the voltage doesn't get too high on the output. (You'd have to use a scope to see peak voltage.)

Re: How to identify antennas?

How can i find out what antenna is for what frequency???? Borrow a network analyzer and check their S11 across frequencies. You'll see one frequency it is tuned for; it will work best around that frequency. Alternatively you could do a very manual test with an RF frequency generator, a 50 ohm resis...

That's true, but I can't see any reason it wouldn't come from the factory that way. Because they don't want to pay for warranty repairs. Because they want to sell more, and the cool-looking body sells more cars than the really aerodynamic body. Because they want to make the car a little cheaper, an...

Like I said, no engineer is going to leave that option on the table. And no manufacturer is going to "give away" potential. Not in the automotive market. They already do. Every vehicle out there is a mass of tradeoffs. Lifetime vs emissions vs top speed vs insurance rates vs 'feel' vs styling. Some...

So they get to charge more for every MWh delivered just because they built a bigger battery? That makes no sense.
Makes perfect sense if that bigger battery allows them to deliver power during a time when utilities pay more for it.
