For obvious reasons there's a lot of focus on Tesla's automobiles, but part of me wonders if these Powerpack grid batteries aren't the real innovation and killer product for the company.

Where's Tesla's secret sauce in this solution: the battery chemistry, the control circuits or well-engineered integration of the parts? How much a threat is constrained lithium supply to the business model?

FYI this project wasn't built with Panasonic / Tesla / Gigafactory batteries. They were purchased from Samsung:

Zero emmissions If nuclear has to include the costs of dismantling the plants, batteries have to include the cost of building them. And wind generators are massive aluminum structures, which are extremely costly to shape. Some day, maybe. Let's be fair in the meantime.

Wind towers are mostly steel.

(which doesn't really change the point)

This outcome is in a particularly distorted badly operated market, one where for no very good reasons regulatory power is not being applied, and distorted bidding for FCAS and peak supply has been the norm. It's hugely politicised, and in the context of a rejection of carbon trading and an attempt by the ruling federal liberal-national government to wedge coal into the mix (it's basically uneconomic now, and won't ge…

Life is hugely politicized We think we’re boxing it off from that but if you look closer, through the abstract nonsense people peddle, you’ll see it comes down to a political yes/no process You’re welcome to pretend otherwise. I’d rather just dispense with the notion life is anything but dialog back and forth, jockeying for acceptance and access into some clique or the “right” to build useful infra

You comment seems to suggest there is some rational decision making emerging from an open back-n-forth of facts and ideas.

I wish that were the case, but the simplest explanation of political reality both in AUS and USA is that our leaders owe favors to a few very rich people, in fact work for them.

Not to the point where it costs $14,000 per MW. At that pricepoint hiring humans to hand crank generators is not the laughably ridiculous proposition it should be.

Tesla is as much a battery company as Cray was a refrigeration company.

It is so obnoxious when a website immediately asks to send you notifications.

I’ve actually never seen it approached any other way (triggered by a direct action), which is somehow even more obnoxious than the prompt itself.

Gmail at least used to do that. There was sometimes a link near the top of the page with text instructing you to click it if you wanted to enable notifications.

Tesla's core innovation is that they don't give a fuck about nonsense opinions, they care about facts - science and engineering.

Plenty of other viable technologies exist, we just need some rich science-aware people to help us roll them out.

There was a link here recently with a video of a consultant talking about a Model 3 tear-down. He basically said the "Skateboard" was amazing, the rest of the car was sub par. The were most impressed with the battery pack, saying it was was above and beyond anything they had seen with cell to cell voltages being astonishingly close.

Also the electronic control systems, motors, suspension, and drivetrain. You know, everything but the fit and finish.

No one has any way to dispose of nuclear waste (except reprocessing, which has significant cost and safety concerns). It sits in storage pools waiting for that day. Lithium batteries have no such issue.

While not cost effective in the slightest, jettisoning nuclear waste into outer space is one proposition. Naturally, launching rockets filled with nuclear waste comes with its own safety concerns.

Elon has the space-launch market covered too, he's one step ahead of everyone.

A human might average 100W per hour over a workday at say 10$ per hour to keep the numbers clean (1$ = 10Wh). 14,000$ per 1,000,000Wh is 72wh per dollar so far cheaper. Except this is instantaneous power so they would need 1,000,000 people to sit around doing nothing most of the day and then occasionally have have some or all of them work, because again that battery caps at 100MW. Really, people in AU don't pay 14$ p…

> Really, people in AU don't pay 14$ per kWh making 14$ per MWh meaningless.

Agreed that consumers don't pay wholesale pricing - but disagreed it's meaningless. Consumers do (of course) end up paying an amount that includes the amortised cost of wholesale power over the course of their contract.

Additionally, there are a range of incentives that result from these kinds of significant, if ephemeral, variations in wholesale pricing. Some of these incentives are bad for consumer, planet, etc.

> They are really paying to keep generating capacity online not for actual power. A backup generator that's never used costs infinite dollars per W, that does not make it useless.

A backup generator that's never used actually is useless.
