So you want someone to compare a starting at $699 m1 Mac to a $10k top of the line pro machine? That you are even interested in this shows how great the m1 chip performs, but as a comparison This is pretty useless.

This still misses the primary reason why hydrogen won’t ever be useful, where lithium-ion batteries can do the job. Hydrogen is just too energy inefficient from an end-to-end efficiency perspective. Lithium-ion achieves a 80%+ efficiency fr

for one, they would agree on one version of how to write standardize. It's primarily about spelling, and sentence cases, constructs etc. It typically adapts to the language, not the other way around.

This means the competition will have to stomach a loss per electric car sale until they catch up to Tesla’s price advantage or not be cost competitive. According to the author Tesla was 3-4 years ahead, with a growing gap given the battery

This! We did the exact same, though our payback period was 2 months of AWS costs. Try and put the base load on your own servers, use the cloud to scale up and down when needed. Cloud servers are a “luxury” that most don’t realise and just t

Absolutely the worst. Ten years ago I encountered a bug in a wireless networking stack that would crash the whole network of nodes. It was in the worst possible location that was highly dependent on timed sending where every nanosecond matt

It absolutely has. It’s basic physics and it definitely applies to batteries or in fact any static charges, which is what is being discussed.

Divided by distance^2 - looks inverted exponential to me. It does apply to spooled batteries, which is pretty much most modern batteries but most importantly Li-ion batteries

There is a somewhat equivalent to that for batteries: Coulomb’s law [1]. The energy contained in a battery increases exponentially the closer the anode and cathode are to each other. Due to this, scale and other reasons, we’ve seen batterie

Electrify America / ionity / Tesla superchargers these days already output 250-350kWh. You could also use those super capacitors in the charging station itself to level out demand. Using them in the grid itself is an even bigger a

The situation is pretty clear. They need to fix the wiring issue. Stick to the regulation or don't regulate... It's also shocking to me that the MAX may be rectified when depending only on one angle-of-attack sensor (the one that

It’s not just China that does this. This is a proven path for developing economies, that still have a labor price advantage. It’s the reason “Made in Germany” exists as a label, forced by the brits to mark “inferior goods” that turned out t

This is impressive, but the most impressive part is that Tesla will likely grow another 50% in the coming year given their guidance. Tesla China can now produce 3k cars a week, let’s extrapolate that to the year at a really conservative 2k,

This! The reason Germany has a high level of proficiency for a country that doesn’t translate media (movies, tv shows etc don’t act as language learning agent), it has a deep and well trained set of teachers. How? Famously the last German e

Minutely so. Tesla’s model 3 is 200kg (~400 pounds) heavier than BMWs equivalent 3 series. Don’t think the tire wear due to that difference will make much of a difference...

Have we not learnt our lesson? Nearly 70 years of massive global subsidies have gone by and yet the nuclear industry has not been able to produce anything competitive, let alone anything that doesn’t require government guarantees / ext

“A new International Monetary Fund (IMF) study shows that USD$5.2 trillion was spent globally on fossil fuel subsidies in 2017. The equivalent of over 6.5% of global GDP of that year” Such a waste. Another example of how subsidies result in

I love it. I recently had to temporarily go back to a 2014 MacBook and it just felt mushy and imprecise. The new keyboards feel sharp and way more precise. Just simply better.

That’s debatable and dependent on what metric you’re looking at. Prior to nationalisation the number of rail passengers in the uk had flatlined for decades. After prioritisation it has been growing like mad [1]. There are valid criticisms a

Mine work perfectly. I’ve heard this being a problem from other sources as well though. Is your phone and/or MacBook older?! If so i suspect the older Bluetooth version may be causing issues here. Other issues: congested use of the Blu

Every GPS device pays a couple of cents to use the system, regardless of country. Whilst this initially may have been peanuts, I’d be pretty sure that this is a self-paying system by now.
