I went to get my U.S. Technician license (I've had a Swedish CEPT2 license for a long time but never been very active) after studying a bit online, and after passing that they asked if I wanted to try the General test too, since I was

Is 50% a reasonable number? It seems low to me, given that electric motors are ~90% efficient, and battery charge efficiencies seem to be around 80%. To get that to 50% overall, the gears and powertrain would have to be < 70% efficient.

Yet traffic means that you can, in practice, do none of these.

Long distance lines are usually so large you don't have to worry about trees falling on them, though.

If US utilities were focused on reliability, they would have stopped putting power lines above ground a long time ago. The power grid in the US is way more unreliable than any other country I've experienced, and I can only think that i

We have one of these, and if the power goes out it's got enough power to run e.g. the fridge/freezer so your food doesn't go bad. It can't handle even momentary overloads, so it's not good for powering motors, but I

It is my impression that things have been changing at SpaceX over the past couple of years. No doubt they are demanding to work for, especially if you are in the direct path of launch deadlines, but as the company's grown they also see

Staying silent is at least better than desperately trying to speak of something you don't know about I don't agree. You should obviously not attempt to make it appear you know something you don't, but asking questions is

Well, to look for life is one of the strategic objectives of NASA's science mission directorate.

Homeowners have a strong financial interest in underestimating the probability of a severe flood I don't know about that. Even if I have flood insurance, it's not clear I'm financially better off by having my house flood. I

No, it's correct. The key is the "... in water" part.

The key is phrase is " ... such that its carbon content does not quickly return to the atmosphere ". Growing grasses for biofuel wouldn't help.

There isn't really a "worst" case here. We can always make it worser...

Sure, if you don't include the word "net". Natural processes account for the majority of CO2 introduced into the atmosphere. They also account for the majority of the CO2 removed from the atmosphere, because there's

IIRC they were not included in the IPCC reports, but for a different reason: even though pretty much everyone agrees that they exist, they were too difficult to quantify.

but we can't be sitting on "a bomb", or it would already have long since gone off. That's a strange argument given that previous variations in climate indeed were very severe...

what might not bother you might be a huge problem for someone else Exactly, that's what I'm saying. It goes both ways. Was your seat reclined?

I completely disagree. I have a neck problem and not being able to recline the seat will completely kill me for any flight longer than an hour. Also, how exactly does the seat in front reclining affect your comfort? Not being able to reclin

Do you completely reject the prescence of existing biases, conscious or unconscious, that give an advantage to males? I would hope not, since such biases have been clearly shown in blind studies by e.g. swapping names on resumes, etc. But u

I disagree. Making arguments by selectively withholding counter-evidence you are aware of to see if those arguments "withstand scrutiny" is not scientific process. Certainly, arguing about which evidence is more important, or how

I have no factual information, but I know that when I write papers where I want to invite discussion, I don't make blatant statements based on a subset of the evidence I have and then expect people to dispassionately pick them apart fo

Long-term that's true ... but just like you can make a fire go out by putting too much fuel on it too early, if you try to light too large a candle, the candle might go out.

But that same argument applies to unions, too. If your company dies, you're out of a job. Why would a union do that?

You're right, clearly American workers are doing great. </s>

If unions are "tyranny of the masses", isn't no unions "tyranny of the dictators"? It's not an either/or situation. As pointed out elsewhere, the relationship between unions and employers in the United Sta

The pay off time for our system here in Hawaii was, if I recall, about 6 years, even though the price of installations is really high. The price of electricity is too, though.

It's not that different, though. Preventative measures show up in many insurance contexts (although I guess usually as a premium discount, not as being paid for by the insurer): fire alarms, and training for motorcyclists and pilots, c
