Re: Tesla Model 3

Tesla had started this WELL OVER A YEAR AGO! Even without the building being finished! https://www.teslarati.com/tesla-gigafactory-1-solar-rooftop-array/ I think you misunderstand me. I was cautiously excited when the GF1 plans were first announced that it would be a huge, energy hungry battery yet...

Re: Manned multirotor

That is so cool!

So much potential redundancy as well. It's hard to think of any single point of failure that could afflict such a design.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

It is like ACTUALLY. Pumping all 10 years worth of CO2 into the environment NOW.....rather than releasing the same amount progressively over 10 years. Which is worse according to current CAGW cult theory ? It actually makes little difference whether X amount of CO2 is emitted now or in 10 years if ...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Yes. Skimming the first 10 minutes of intro out of a 4 hour video series isn't going to be very enlightening. Like reading the preface of a book and calling it done. I consider it like reading the abstract of a paper - it tells you if it's worth reading the rest. In this case I'm not overly interes...

Re: Thyristor-based load switching

I meant isolation in the sense amberwolf said - when the contacts are open the load is guaranteed to be isolated. It's something I recall being told was required to meet an electrical saftey code - no solid state switches allowed. Contacts can weld but contactors would appear to be much more toleran...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

It is also comparing the best of very mature ICE technology to the worst case BEV (Tesla batteries are by far the largest on the market) with fledgling battery tech. EV battery tech must, and likely will, follow other electronic tech and become cheaper and less resource intensive (same thing, really...

I think one of the reasons contactors get used is for safety's sake because they provide galvanic isolation

To sum up what I say in the fewest words :" Things will be much smaller and simpler in the future".
Should we start culling people now while we still have fossil fuels to make metal tools? Or should we just wait for 90% of the population to starve to death in our new medieval world?

Re: Wind and Solar vs Coal, Gasoline, Nuclear

No one is expecting a 1:1 easy replacement for fossil fuels, but you've preached a post-apocolyptic world and the end of humanity as we know it.

This simply encourages the "no point even trying" mindset.

Endless consumerism has to give, that's widely accepted.

Re: Aluminium vs steel contraction when frozen

Honestly, it's well known brain-teaser as to whether the hole in a ring gets bigger or smaller when it's heated. The trick is to mentally uncoil the ring into a rod. When you heat a rod it obviously gets much longer than it does thicker and if re-bent into a ring it would have both a larger outside ...
