Comment Actual data from the FAQ (Score 4, Interesting) 58

From https://www.masscec.com/massce..., they expect to draw 3kW - 10kW for 3 hours, for a total draw of 9 kWh - 30 kWh.

We have a Kona EV with a 65 kWh battery, which we limit to 80% charge to maximize battery life. Their expected draw is 14% - 46% of battery life. With our existing V2L adapter, the Kona can specify the minimum battery level where it will cut off. If we set it to cut off at 60%, then they could have 20% of the battery, but no more. 60% is enough for all our expected driving for a couple days, so I'd be comfortable with that. But also, odds are that the power drain event will be in the evening, and there'll be plenty of time overnight to recharge back to 80%.

Lithium batteries don't like being charged all the way to 100% or drained to 0%, but running them back and forth between 60-80% won't measurably damage them for thousands of cycles.

If the software were better, we'd be able to say, "We want to be back at 80% at 5AM. And in any case, we want to keep at least 60% of our battery for our own needs - driving, V2L for our own house in a power failure, etc. Within those constraints, you're welcome to the rest of the power, but we're selling it at $0.60/kWh. If you *really* want power, we'll go from 60% to 40%, but it'll cost you $1.00/kWh below 60%." And then the grid could decide whether it's willing to pay our price, and how much it wants.

Comment No, only 15%. The rest are the consumer. (Score 3, Informative) 104

See https://www.iea.org/reports/em...

"Today, oil and gas operations account for around 15% of total energy-related emissions globally, the equivalent of 5.1 billion tonnes of greenhouse gas emissions."

The 50% number is like claiming that Taco Bell is responsible for the water use of people flushing the toilet after eating a taco.

Comment Yes, but remember the goal of the deal (Score 1) 25

Was not to support local news.

It was to support the politicians complaining about Google search eating local news. So they would stop pushing an even more costly legislative solution.

Simply supporting local news wouldn't have achieved that goal. Because no amount of support would solve the problem that people just aren't reading newspapers and watching local news anymore. They're getting their news through social media. Which, other than YouTube, is something Google is kinda terrible at. See Google+. Or more accurately, don't.

Comment How many snippets occur ONLY in that open source? (Score 4, Interesting) 47

I've implemented linked list traversal f*ck-all-knows how many times over the last 40 years, in a dozen languages. I'm sure similar or identical code exists in hundreds of open source repositories. And millions of CS homework assignments over the decades.

If you compare my code with enough projects, I'm sure you'll find matches. Not because I copied them or Stack Overflow (I was coding long before that was a thing). But because there are really only a few sane ways to implement most algorithms. Which is also why most software patents are stupid, but that's a different can of worms...

Just got back from Indonesia. Photographed on the way in and out. Fiji, too. Philippines. And so on.

Honduras has taken fingerprints for at least 10 years. Their fingerprint readers suck; you really have to press on them to get a good scan.

Even in the US, SFO airport has been taking photos on the way in for US citizens for years.

Comment Generalities are easy. Specifics are hard. (Score 1) 87

I'm sure anyone can look at the globe, or even their region, and come up with at least 30% they'd be happy setting aside for nature. I sure can.

The problem is that we're going to disagree over which 30%.

Ranchers: the 30% which isn't suitable for grazing.
Oil barons: the 30% which doesn't have oil underneath.
Miners: the 30% which doesn't have useful ore.
Fishing fleets: the 30% which we've already depleted of fish.
Developers: any 30% we don't own and want to put houses on.
PG&E: the 30% we don't need to run power lines through.
Normal folks: anywhere is fine, but housing and gasoline and food all cost too much, so it better not raise the price of any of those.

It's like housing the homeless. Even here in California, where the vast majority of people agree we should build supportive housing, nobody wants it built in their own neighborhood.

Comment We passed peak total world IQ a long time ago (Score 1) 243

Hopefully total world IQ will drop more slowly than total world population.

Meanwhile, all those ecosystems we've been pillaging to provide food, clean water, energy, waste disposal, etc. for a growing population can start recovering, if we manage to avoid hitting a tipping point in the meantime.
