It might help to note that in 2009, Australia imported 900,000 tonnes of urea. Gonna take a long time before they meet that demand. Australia's an energy importer, big time. Sure, bargeloads of coal go out to places like Saudi Arabia

Here's a fun little exercise with the Toyota Mirai. Read the spec sheet, and read the wikipedia article. They claim the thing can hold 5 kg of H2, at 10,000 psi. Look into how big the tanks are. The math will show that at that pressur

Australia does not have huge deposits of hydrogen they're just sitting around trying to find uses for. So the input for this technology is imaginary. Making ammonia out of hydrogen, which is so useful that half your food comes from it

Find a customer, any customer. If you're light years ahead of the competition, they'll say so. If you built something you can't sell, then it's not worth anything to the market. Don't worry about your superior comp

Obviously something has to give. Pretend I'm the guy you'd hand your resignation letter to. Can't we talk this over? What can I change so that you'll enjoy working here again? Why didn't you just say so? I believ

But Monty's only being helpful if I guessed wrong. If it actually was behind door #1, Monty's trying to entice me into picking a goat, and basically being a dick. This is also assuming he could've just opened door #1 righ

You can distill the disconnect down to one question. Does Monty know where the car is? (The original article says he does, but this often gets lost in the version people read.) Suggest Monty doesn't, and he opens door #3 to reveal a g

There's a reason alcohol is so generously consumed in airplanes and airports. Obviously you don't want to show up at a rental car counter or business meeting stinking drunk, but it's amazing what just one drink can do for yo

There needs to be written (and if given the time I'll write) a yelp specifically for engineering interviews. Only interviewees can give reviews, and reviews will be restricted to binary yes-or-no questions (did they inform you of a de

In ten years, I predict we'll have started transitioning to aluminum-ion batteries. Lithium has one valence electron. Aluminum has three. Aluminum-ion cells are not new, and they do have issues, but the same can be said of Lithium-ion

There's a reason this is standard operating procedure among gyms. They know their target user is only going to actively use their product for a limited time, and the subscription model is sticky enough to monetize it for much longer.

Millennials don't have enough money saved to apportion what they're saving. As of 2017, 46% had 0 money saved. Another 36% had <$5k saved. I don't think there's anything long-term about a 4-figure bank balance.

It's more than perception- if I had been called into unscheduled one-on-ones with management about incidents that happened, even where I feel like I did nothing wrong, that's a data point that matters. No one-on-ones after 25 yea

Like others, it was just about 100% (I earned more in a year than I had) and that was only about 10% down, subjecting me to several years of PMI. The ideal percentage of your total net worth sunk into a down payment should be zero, because

Unfortunately this type of training is like advertising- a good chunk of the money spent on it is wasted, but they can never figure out where or how large the percentage is (or needs to be). But we still have, and even live by, advertising

I disagree with the other responses. It's a simple question of practicality. If we entrusted attorneys with both criminal defense and prosecution on some kind of ad-hoc contract basis, there'd be way too much temptation to mix t

There are two approaches worth considering. Evaporative cooling is not worth doing in Boston for the space in a residence. It can be used, however, to improve the efficiency of refrigerated air units. Take a look at air conditioner mister

If you define a whole house fan as a whole-house swamp cooler without any evaporative media or water line, then, no. If you define a whole house fan as the part of the whole-house swamp cooler that is a huge fan and covers the whole house,

Software dev as an industry tends to be bifurcated: startups and unicorns tend to be very anticredentialist, at least when it comes to formal education. They'd rather see X years at Y company than really care what school you went to o

Gmail used to do that for free, and if you signed your domain up, you're grandfathered in (I have a few domains still like that). They don't do it for free anymore, and their mail hosting for new accounts is surprisingly expensive

I take a different approach; I've zoomed out from the problem, and looking at it from a macro level, I've concluded that the system is what's corrupt, not the candidates, recruiters, or hiring managers, and all of the individ

A scientific approach is to pose a theory (this candidate would make a good hire) and perform a measurement (whoa, this guy's good) and then perhaps perform the measurement again, without bias, to see if the measurement is consistent a
