Comment batteries cost money (Score 2) 260

And those batteries cannot hold a charge for 6 months anyway.

Even if they could, you're talking about a deficit of about 1/3rd at the peak of winter and a corresponding surplus in the summer. So let's assume you have a 1/3rd total energy surplus for 2 months in the summer and have to hold it 6 months until winter where you use it up.

That'd be 2900MWh times 61 or 177GWh. that's 177M kWh. A Tesla pack holds 85kWh, let's assume it's about to become 100kWh. And the pack costs over $10K, we'll assume it costs $5K.

That would mean they need 1,770,000 packs, at $5K a piece or $89B worth of packs. It's also the entire output of the plant for 3.5 years.

Does this seem workable to you?

I think you're not getting a good grip on the actual size of the problem.

> Is it getting major tax breaks?

Yes. It's getting huge tax breaks here. It got a nearly free auto plant from California.

It gets $7500/car in subsidy from the feds. Many states give $1500 to $5000 on top of that. Some countries they sell into give tens of thousands equivalent.

And this is beyond the emissions trading money it gets, which is a subsidy, but not directly from governments, just enforced by the government.

>becasue they are high end luxury vehicles. Do you send letter to Mercedes telling them their care a rudely expensive?

If they charged $90K for a car which is luxury equivalent to a Hyundai Sonata I would. It's a nice car, but it doesn't measure up to other $90K cars on luxury.

Comment "some storage" (Score 2) 260

From the article:

"Reno gets an average of five peak sun hours per day."

Remember, as soon as you say the word "average" you are counting on a huge amount of storage so that you get the average amount of energy every day, even if that day is below average. And even if every day for the last two weeks has been below average.

In in fact, if you are using solar, you have to understand that nearly every day between the autumn equinox and the spring equinox is below average. That means you need enough storage to store up electricity all summer so you can use it in the winter! This is not at all realistic. More realistic is to make sure you produce more than you need in the summer and enough in the winter.

This does use more than solar though. However, I can't believe this guy counted the windmills in a PR picture.

Anyway, buying and erecting a 3MW windmill costs about $10M. That would mean Tesla would spend $850M on windmills. You cannot seriously think that Tesla is going to spend $850M on windmills before the plant even opens.

This isn't seizing. This is ordering an entity to produce evidence. Yes, the US could order a US company to produce the contents of a safe deposit box in Europe. If the company doesn't comply, the US arm would be fined until it does comply. That is if the US couldn't get cooperation from local authorities to get it seized.

The US government isn't saying anything about other countries' laws not applying. The US government is saying its own do. Where there is a conflict, it really isn't the US government's problem, it's MS' problem.

And this whole thing works in reverse too. US companies in the EU are required to comply with EU laws, including producing evidence that is outside of the EU.

Just to wonder, if you really believe that out of the US is out of the US' reach, you must be really shocked to hear of the IRS now finding out about money in offshore accounts and taxing people on it, eh?

California has had 2-3 of these running for decades. Yes, newer ones are bigger, but even the smaller ones like the one in Coalinga can fry a bird if it flies near the focal point.

Maybe just stop building these. They are quite expensive. They are the most expensive source of electricity, bar none.

"that may result in an unauthorized effort to adversely impact the security, availability, confidentiality, or integrity of an information system or information that is stored on, processed by, or transiting an information system."

It's not an effort (authorized or unauthorized) to adversely impact any of those things. It is an effort to deliver video.

You changed "effort" to "impact". You're changing the meaning of the sentence.

If someone were to hijack Netflix' traffic to create an effort to deny service, then that would be a denial of service attack and ISPs could counter that, as ISPs already counter DoS attacks.

According to the bill a threat is anything which is anything which is part of an unauthorized effort to deny access. Netflix streaming which inadvertently leads to a denial of access would not be part of an effort to deny access.

Here is the bill.

One of the companies who makes the launch system was required to take out a license to produce the boosters themselves. This is the backup plan.

It's not a great backup plan, because just having the plans and license doesn't mean you necessarily can make them, especially with the reliability needed for defense launches.

What 900 lumen light are you using?

I've got a couple 900 lumen lights and they're bright enough that if I shine them at cars the drivers are mildly upset about the brightness. It's like hitting them with high beams (although not covering as much area as a headlight).

I agree 200 lumens and the down-facing output is strange. I expect this is for urban riders who mostly use the streetlights to see.

And why do they use TCP if they are trying to avoid retransmissions due to lost/corrupt packets?

This seems to say that it's most trying to avoid link-layer retransmission, not transport-layer. So somehow I need to figure out all the links my transmission is traversing and disable link-layer retransmission on all of them?
