Ed is right, and young engineers were more respected in the '60's than they might be today, so they made a pretty good living.
Indeed, although there is a widespread misconception that the Teslas are fast because they have high torque from 0 RPM.
The reality is that every powerful ICE car has too much torque in first gear already and are traction limited. The Tesla's cannot be beaten from 0-60 because they have incredible traction control that keeps the car on just on the edge of wheelspin. The "launch control" that other companies offer is terrible by comparison. Most of them still just light up the tires or cut throttle aggressively.
It just seems like Tesla's control loop runs much faster.
Well, long time ago Engineers were people doing Engineering work, not just technicians that are called Engineers today... Who would pay you for the name, not for the job done?
Well Anatoliy,
Technicians were called Engineers in various counties doing service work, so there is precedent. That was very early in time, so not a recent thing. Here in Canada, the two names are not interchangeable at least.
As far as Engineers are concerned, many make silly mistakes that a decent Technician wouldn't make. It might be that they should be hired in pairs. The engineer thinks of a concept, the Technician makes it work. 🙂 As for worth, how much is a good technician worth? ... a so-so Engineer? There should be crossover there because just having the ring does not guarantee a good engineering job will be done.
I am a technician by formal education. Engineers have often called me an engineering technician. That education was on my own.

If you are Technician by formal education, but design engines that will sell and bring huge money to the company, you may get your Bently money, unlike some Engineer that takes care of one engine made by your company, right?
Can't charge overnight. No sun.
In sunny calif wont need to charge at night. Much. In winter just plug it in over night. Already charged in day time. Just sitting outside in the parking lot while at work inside somewhere. Come out... all fully charged up and ready for the long commute home stuck in traffic.
Tesla owns a solar company... sooner or later they will realise I am right and make a roof of solar melted into the roof structure. Its just a matter of time. you heard it here first.

Maybe. I have seen figures of about 15W per square foot quoted online for current solar panels.
If you have an 85kWh battery...
Hi Anatoliy,
Yes, that is exactly right. Something I realised many years ago and I am currently attempting to do something along those lines. I already built up a company from nothing and sold it, so this time around I know how much work to expect building it up. We shall see. Like the first time, dependence on others is the trouble spot.

I was told in 1970 while in London that 'engineers' did not get the same respect as their peers in the USA. It is a class thing I think, working with technical things and all.
It is interesting that IBM was one of the first companies to dilute the term 'engineer' by calling many people 'engineers'. For example 'environmental engineers' were actually custodians. It would appear to have been an effort to raise morale in the ranks.
However, generally there was a distinct difference between an 'engineer' and a 'technician. I started out professionally as something in-between, where the experienced and better educated (in engineering) people designed the electronics, the technicians built it, and I had to make it work. I wasn't really called an engineer for the first couple of years after my graduation (physics), but I learned my craft, and by 1968 was doing my own design work, with help from more experienced engineers. I learned engineering design on the job at Ampex, putting most of my lunch hours in the technical library, and with after hours classes taught by professors or visiting engineers. By 1968, however, I had developed the complementary-differential input stage and achieved the 0.4nV/rt Hz input noise that I still achieve today, with my best designs.

Hi John,
0.4nV/rt Hz input noise in 1968?? That's impressive. What transistors did you use back then?

I found both the 2N4403 and even better, the 2N4405. Four 2N4405's in parallel, or eight 2N4403's would do it at a few ma each.

Hi John,
Interesting. What made you think of running transistors in parallel to begin with? Did you take the time to match them or not?
-Chris

I did not invent it, I got it from a 1975 paper in 'Electronics Letters' from my company's technical library.
Matching is best, but for low Z drive, 2-20 ohms, probably not that necessary. High beta is preferred, however.

Lover rbb, the same why I used medium power transistors in microphone preamps. Simple theory of semiconductors.
Mercedes already did that in the Maybach. All they could get from the cells was enough juice to run some cooling fans however. There was a weird car for the ultra low power competition years ago covered with cells but not something you could drive to work.
The RV with solar panels probably would not work that well either. Not enough solar generation to get far.
Solar panels are already pretty high efficiency so don't expect a breakthrough. If they are at 26% now (Best performance Solar cell efficiency tables (version 50) - Green - 2017 - Progress in Photovoltaics: Research and Applications - Wiley Online Library) and that's 10% of the power needed you can't get where you want to be.
I did some work with Bentley and saw a lot on the inside that was not too impressive. The Bentley, Audi A8, and VW Phaeton share the same chassis and drive train. I heard that the VW was the best built of the lot. The Naim audio w. BMR speakers was not serious as we would think a premium audio system should be. The tuning was all done in Germany. The Naim amp cost $1M to certify (The car biz is not easy to make money in) and not made by Naim. Only Tier 1 vendors need apply. At one point the Naim guys said they were lending credibility to Bentley!.
