Re: Wind and Solar vs Coal, Gasoline, Nuclear

You can't compare carbon in the active carbon cycle to the release of sequestered carbon. This is the mistake that people make all the time. If the cow didn't eat the grass, there wouldn't be additional methane in the atmosphere EQUIVALENT of that amount of carbon. So I'm not yet convinced the mist...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

the production by ruminants in and of itself isn't a big deal A cow does on overage release between 70 and 120 kg of Methane per year. Methane is a greenhouse gas like carbon dioxide (CO2). But the negative effect on the climate of Methane is 23 times higher than the effect of CO2. Therefore the re...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

That's net production. In terms of climate change, cut a tree down and burn it you produce CO2, plant a tree and grow it you reduce CO2. That's what we call "sustainable logging", which is the only way to do it in Oregon by law. That's not the same thing as deforestation though - in case of defores...

I don't think it's very much.
It is estimated that 25% of the world’s total greenhouse gas production comes from deforestation alone.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Maybe people are, but it would take a 100 years for over half of the world's population doing exactly what we've done in the West before they approach the same level. Those should be pretty humbling numbers but they don't seem to be. Well, by the level of industrialization and use of machinery the ...

I don't know if the plan was always for these features to come only after expansion is over, or whether they'd grow with the factory and things are behind schedule. Realistically it is probably a product of $$. They're just short in terms of budget at this time having multiple crazy projects going ...

This was achieved without battery changes - just motor efficiency improvements, software changes and bearing changes.
That last part is incredible in its own. If I'm not mistaken, the number I've seen was something like 97% motor efficiency. Did you catch it anywhere, is that accurate ?

Tesla announced a net loss of $702 million for the first quarter, translating to a loss of $4.10 per share. The company also listed $4.5 billion in revenue, which is below Wall Street expectations. https://www.teslarati.com/tesla-tsla-q1-2019-earnings-call-updates-live-blog/ I'm sure people will dr...

The chart looks somewhat suspect. Aren't EVs significantly simpler mechanically ? Why does it take the same amount of energy to make one prior to the battery manufacturing ?

Re: Thyristor-based load switching

I think one of the reasons contactors get used is for safety's sake because they provide galvanic isolation That's not really a fact. More often than not contactors have the same coil voltage as the main voltage they're switching, so they're activated by directly applying pack voltage. There is not...

Re: Thyristor-based load switching

Like FETs, a common failure mode of Thyristors (SCRs) is shorting anode to cathode. So...you would be unable to use the switch to disconnect the load, and if the purpose was a safety disconnect, it would be unsafe. And contactor can have the contacts welded and being unable to disconnect :) Solid-s...
