Comment Re:I look to the manufacturer (Score 1) 128

Merck is not more the manufacturer of ivermectin than kodak is the manufacturer of cameras. Their patent experied a long time ago, and currently hold next to nothing of the current market. They have nothing to gain on the success of ivermectin. However they have invested big in some patentable covid therapeutics. I would hardly consider them a authorative source on this.

0F isn't just "cold"... it's the point where even someone in good health, with proper protective clothing, is likely to be at serious risk of injury or death if literally anything goes even slightly wrong. Likewise, 100F (wet bulb) isn't just "hot", it's the point where you're in active danger of heatstroke, EVEN IF you're literally hiding in the dark in front of a big fan.

Are these meaning of values something fahrenheit users are all grown up to know

Because that would be highly imprecise. Risk of heat stroke happens when the body hits 104 degrees fahrenheit. Not outdoor temperature. 100 degrees in a dry desert is no problem as long you have water and shade. Body temperature is fine, as sweat will quickly evaporate and cool you to lower than 100 degrees. I would argue 80 degrees in 90% RH can be more uncomfortable as sweating is much less effective. 99 is safe and 101 is not, could be a dangerous idea

As for the 0 degrees...

According to a story in Germany, Fahrenheit actually chose the lowest air temperature measured in his hometown Danzig in winter 1708/09 as 0 F, and only later had the need to be able to make this value reproducible using brine.

Freezing point of saturated salt water is actually -6 degrees fahrenheit. It is dependent on salinity, which varies on geographic location. Hardly precise.

Comment Re:Fueled by gov't subsidies.. (Score 1) 206

I've always wondered how many people would be driving electric cars if it wasn't for the state/Fed subsidies (rebates) or other benefits like Leaf's free charging.

I've always wondered how many people would be driving ICE cars if they had to pay to remove the CO2 that they are pumping into the atmosphere.

I would say currently about 70.9% of new sales. That is the case in Norway so far with heavy taxes on ICE cars and no taxes on electric.

Comment Re:Mild Hybrids (Score 1) 240

You are mostly correct. Consider the strongest Tesla at 581kW. Assuming we do the same in one 48VDC motor we are talking more than 12kA !! Even more on the AC motor side. Even ignoring the massive wires (well bus bars) and converter costs, I don`t think this would be any safer than any higher voltage system, which is the general reason for going 48V.

I`ve tested short circuits with 24V systems with 100A capability, and the arc is scary as fuck without a contactor to do the contact. I did it once by hand thinking it was safe, got a huge fireball as plus hit ground, bounced it slightly before reconnecting and the wire caught fire and welded stuck surprisingly quickly. With 12kA nominal capability I can`t even imagine. And the di/dt effects of parastic inductance could make all kinds of interesting effects

That said, for a low end hybrid I can see it work. For instance a 16kW system with 400A could be doable.

I`m no tax expert but I believe it`s done like this:

  • 1) Buy services or import overpriced goods from a business you own in a tax haven.
  • 2) Scale the above till you barely profit in the high tax country, but have massive profits in the low tax country
  • 3) Pay low income taxes in the low tax country
  • 4) Profit!

I believe you will not have to pay income taxes more than once. At least as long as you keep the money in the business set up in the low tax country.

Comment Re:People actually *like* Python whitespace? (Score 1) 339

Subjective stuff I guess. Me on the other hand throws a sigh for every brace I have to write. Or even sometimes move to make another original authors program intent readable.

Ive only ever encountered a problem with the whitespace when tabs are mixed with spaces. Which really was a major mistake to allow. But as long as its edited in an IDE, they all protect against using tabs for whitespace anyway these days.

Comment Re:Is C.H.I.P. really sub-10$? (Score 1) 122

16$ for the allwinner is not true. I remember a few years back some of their cortex a9 chip made lots of problems for the industry that they sold it for around 5$. I wouldnt be surprised if its even cheaper now.

But even if it were true, they havent offered a single CHIP for 9$ yet. Only 29$ + "free shipping". Shipping something like this from shenzhen would cost around 1$. So it`s really a 28$ module so far. Hardly a loss leader by todays standards. You can already today get android phones with touchscreen, gsm, camera, gps and a battery added in as well for 7$ more(35$).

Comment Re:Where again? (Score 1) 102

Flamebait responding to flamebait. Who wants to respond to this?

Well me apparantly, since I don`t get this comparison that frequently comes up. The geographic knowledge of internal states of a nation is more detailed knowledge than geographic knowledge of reasonably sized nations. Not just a size thing either. Wyoming is big, but Sakha is 12x bigger, and most people still don`t know its location.

Oh I`m pretty sure you wouldn`t want to be near any sort of metal penetrated high voltage super capacitor. I mean high voltage, low ESR, high energy density, short circuit. What could possibly go wrong.

On the other hand. With so much energy and power density, there is so much that could go right!
