24 hours in a day, at 500 watts is 12kwh. The average cost of electricity is 12 cents/kWh. Therefore the profit minus electricity is $4.56 per machine per day. You would have to factor in wear and tear on the hardware. Right now, with bitcoin so high, it is somewhat profitable to mine, but there isn't a guarantee about tomorrow's value.
They wouldn't be rich at all without everyone else doing their part. And they are so rich it's nearly impossible for them to lose enough to become one of the commoners again no matter how badly they screw up.
And this is why automation in manufacturing, service, and military makes me nervous. What will happen when they are in charge of it all and plebs aren't needed?
Parent poster was looking for a car analogy. They meant to say "whelp, looks like I'm buyin' anything but OEM parts on this puppy...". iPhone, the Jaguar of phones.
The clicking noises are probably noise leaking into the audio amplifier from the modulation of the NFC radio. The frequency of the radio is out of hearing range but the modulation is not, and intermodulation can appear as low frequency noise. My iPhone lte radio has done the same thing to land lines on several occasions.
As someone with a masters in mechanical engineering the 30% figure cited for many heat based engines bothers me greatly. This is only true if you have access to a sink colder than interstellar space. A more realistic efficiency is the relative one given the cold side temperature you have to work with. Under this metric, modern ice cars fare much better and can be over 80 even 90%+ efficient.
Next up, isothermal cycles and how the oft forgotten heat flow raises my ire.
Yes, switch to a hybrid if CO2 is your thing. Grids change on the order of decades, waiting it out is too slow. Switching to a solution like electric when there are better options for the grid energy, like a hybrid, dosent make sense.
Fig 3 shows how GHG emissions from the use of EVs varies across the EU: while in Sweden the use of BEV would produce only 7–9 gCO2eq/km, in Latvia EVs emit 169–234 gCO2eq/km and the EU average is 65–89 gCO2eq/km (the first number of these intervals refer to the 14.5 kWh/100 km BEV while the second to the 20.0 kWh/100 km BEV). According to these figures, the use of BEV in countries relying on big shares of nuclear or renewable electricity would contribute to reducing GHG emissions at the national level, while, in countries with a highly carbon-intense electricity mix, electric cars would not necessarily contribute to GHG emission reduction targets than relying on ICE vehicle fleets.
tl;dr the paper itself says if your country has clean energy then electric vehicles are cleaner than diesels, whereas if you have dirty energy, like much of the USA or worse, India, electric vehicles are a wash. Id add that looking at fig3 it also looks like the worst countries would benefit more CO2 wise from hybrids than electrics at least in the short term till the power isn't so dirty.
These require material to train them and the responses tend to reflect the participants nuanced behavior. I mean, what do people think is going to happen when you force feed it, eyes taped open, to 47 million social media feeds? Seems to be some kind of fine line between an algorithm and portal to hell. Well, at least they did better than Microsoft
Sneezing can spread disease, sometimes even serious ones, there have been studies, and it's likely far far worse than a reasonable amount of second hand vaping fluid. It probably should be mandatory to cover up or face fines.
This needs some more mod points. Perfume is at least as bad if not worse than vaping. While I think its ridiculous to ban vaping in all the same places as cigarettes are, we do need some base laws because of the ruining it for everyone people. Strong odors when you are forced into small enclosed spaces should be banned (I'm not even allergic to it and I nearly threw up on an international flight just sitting next to someone), as well as other douchebag things like strobing lights, etc. Until the toddlers of our society grow up, so forever, we are going to need a bit of a nanny state to go make them sit in the corner and think about what they did.
What kind of dust was it? Cheeto, brake, nose candy? Maybe you were simply traveling too fast? Left somewhere in a hurry? My bet is just that the guy had no clue and just wanted to dust you off.
On the flip side, with end goal AI and cheap automation/robotics zero employment is possible. The ruling class won't need subservient humans to provide the luxurious lifestyle they enjoy so much - except a few just for the fun of harassment.
there is little interest in applying technology to overcome the massive human problems of the world.
Completely false, even says so in the summary. Throughout history, if the general population was upset with the ruling class they overthrew them. With automated factories and armies, total control will soon be put in the hands of a few people, unlike all of history. Heck, with all the automation there won't be a need for the plebes to create the luxurious life they are accustomed to. I'm pretty sure Oligarchs agree, this will overcome a massive human problem.
Economy crushing is highway speeds. Slow discharge rates for lithium cells are on the 1-2 hour+ scale. Fast discharge is on the 5 minute end, like a drone or dragster. These batteries do nothing to help range anxiety, to the contrary of what the article claims.
Exactly. It does become practical when you include liquid cooling in the charging system. At 746 watts per horsepower and the famed inefficecy of combustion engines, we already successfully deal with an order of magnitude more heat energy/time. Further use of a supercapacitor bank, or large battery bank, on the charging side could provide far faster charges at the cost of some duty cycle. For example if you assume a 6 minute charge, and and 6 minutes of down time, you only need half the grid connection at full usage.
The 6 minute charge time capacity is better than anything on the market or so it would seem. They say it is high energy density, but don't actually say what it is, you would think that if the specs were good they would be disclosed. Going off thier prototype cell in the link I calculate the volumetric energy density at about 540 watt hours/liter which is about 20% below the higher end of capacity on a volume basis. This battery may actually have the highest actual capacity at high discharge rates, which is why similar batteries have been used in racing electric designs, and be more robust to degradation than most lithium cells, which is why it was probably used in electric cars (cheapest battery per mile), but for slow economy cruising even the new battery is still on par with or below the performance (mileage per size/weight) of existing technologies.
The problem with that whole idea is that sound doesn't behave like laser light.
Actually sound does behave like light, when you look at it by normalizing the wavelength difference. Directional audio gear like this one from lrad can operate a fairly tight beam, with higher frequencies being easier to focus. Both biological and chemical sources would leave a trace of thier presence, and while we could be lied to, if you take reports at face value, sound seems the likely vector.

For small values of 6 this is accurate.

Yea, yea, yea, first born something, surrender your immortal whatever, blah, blah blah. What's the point of reading something before signing?
It would be truly mind blowing if this created neither, but instead a strange/quark star.

Why compete when you can collude with no risk?

For example if you assume a 6 minute charge, and and 6 minutes of down time, you only need half the grid connection at full usage.
For a full charge with economy driving it's 80% of today's batteries. Not even more, nor twice, nor thrice.
