Comment ANyone else find these headlines, bait annoying? (Score 1) 174

There have been droughts, and famines, multiple times in the millenia that mankind has walked this earth. While some of them may have been due to some local ecological issue (earthquakes, vulcanism, etc.), Suggesting its about climate change is like saying the next card after the King of Spades should be the Ace of Spades. The arguments over whether climate change occurs drive me so crazy.

We know climate changes, anyone who's had any geography or history knows this. That's not and is not the issue. The issue is whether the current change is:
  • 1. Exasperbated my mankind's development of natural resources, and the consequences to air, water, and other environmental qualities
  • 2. Whether the developments that mankind is responsible for actually have an appreciable impact over and above the natural climate cycles.
  • 3. Whether the primary heat source in our solar system, IE the sun, is perhaps also changing (getting hotter) and thus impacting the earth as well
  • 4. Given any of the above if true, what steps should mankind make, to try to adapt to this scenario that are reasonable?
  • 5. Whether we should basically kill industrialization in some foolhardy attempt to prevent what likely is going to occur in the not so distant geological future and the consequences on human society, international cooperation, etc.

No matter where you stand on these issues, arguing over whether it occurrs, acting like people who disagree with suggestions to help, as if simply suggesting solutions equates with fixing the problem. (when it is just as likey that some actions we take may make the problem worse or have no impact: Ex: the conversion to ELectric cars, that require massive power storage and generation to account for the transmission of it to homes. As an engineer, the thought that by switching to such sources, solar, and wind in all circumstances will somehow fix something, or are the right choice and that governments should compel by force of law, is far more likely, from where I stand, to cause issues in some regions beyond what we may be thinking is helping. LIke it or not, mankind still has a lot to learn about the climate, the oceans etc. Because of this, I'd rather here solutions discussed, and considered on their own, without the kind of hard ball that some politicians seem to want to play.

Comment Re:Better Battery/Charging Tech is needed (Score 2) 93

That feels like kind of a 'well duh' if its in the garage it doesn't matter much. The problem is, and this is where I struggle when I think of when I'd consider buying one. It travel over the mountains from Virginia into West Virginia frequently enough, getting to my relatives is within range usually, but I wonder if charging while visiting is an issue when your destination lacks the same charging equipment. To me that's really the bigger issue, that and capacity in the Grid.

My main question this morning is, how much speed can we reasonably expect to get out of these things. For people that live in large cities and never go anywhere it likely does not matter to them at all. Its rural, out from the big cities where people are like well how would that work for us?

Comment Better Battery/Charging Tech is needed (Score 2, Interesting) 93

I think most of us know that better battery and charging tech is needed. Many keep reminding us that the grid likely will have to produce a lot more electricity to be able to support all the future electrified vehicles.

However, I worry sometims when I read about how they are going to make batteries better, charging faster. As a Computer Engineer with some Electrical Engineering in me, I can't help but wonder where that improvement could come?

Will it need to come in:
  • Transmission/Generator Side - IE Find a way to not lose as much power during transmission over large distances
  • Battery Capacity - Able to store higher energy levels
  • Battery Size - Able to store higher energy levels in a smaller form factor
  • Charing Capability - Able to put more charge faster into batteries
  • Generator Power Loss - Loss that may occur at the plug in generator transitioning from a Traditional AC current, into whatever form the battery needs (voltage/amperage/AC/DC) to charge
  • Power Recovery while driving - Find a way to use the forces already present in a car to send back some energy as power to improve charge life

However, I severly wonder if there is a hard limit on just how fast any battery can be charged. It likely is linked to a function of the generator's overall max rated load rating (in terms of voltage/charge/amperage) and the max capacity / impedence of the battery / system to get to the battery. I know there have been some improvements over the last few years, but I wonder if there may actually be a physical limit to just how fast this can be done.

Then there are thoughts I have about how battery tech may be applied in EVs. If you can charge multiple batteries in parallel, one car at the same time as opposed to one massive serially linked one maybe you could get some gains that way.

I am not downing on EV tech, the engineer in me has doubts about how far we can reasonably push things with current technolog potentials.

Comment Re:"industry partners".. that's funny (Score 1) 78

The only problem with this reasoning, and for me personally I could see myself maybe considering these sorts of things. If we are talking commercial flights, they often are going that way whether you buy a ticket or not, whether the plain is at capacity or not. So not taking a flight because of this alone seems like not enough info to reason around. Just my opinion.

I've had the same objections to recent FCC proposals. They say X speed should be standard for broad band, but is that for a 1 person dwelling a family of 4? Nevermind that device number has exploded in the last ten years. IOT will only make it worse. We have a family of 3, used to be 4, and I had to go up to a 150 MB/ Sec Plan minimum to worrk from home, when the kids got game consoles that chewed through data like nothing. We boughtt he unlimited 'package' to remove the caps, but its still crazy what they may do on this stuff.

" In that vision, there is room for only some of crypto's underlying technical features, like programmability and tokenization, not for cryptocurrencies themselves. "Our broad conclusion is captured in the motto, "Anything that crypto can do, CBDCs can do better,'" said Hyun Song Shin, an economic adviser and head of research at the BIS, during a press briefing on Monday."

If there is no room for some of Cyrptos technical features, how can you turn around and say CBDCs can do better? This statement seems dubious to me.

Comment Re: Religion is belief without evidence (Score 1) 517

Actually that's not correct. Religion has always informed politics and government, acting like that is not the case is ludicrous. What the First Amendment did was prevent any one religion being enshrined as a national one, at the expense and persecution of all others. That's what it was intended for.

You cannot call yourself an engineer in court unless you have passed the 'fundamentals of engineering exam', practiced as an engineer for sometime, and been certified as a professional engineer. I can count on one hand with no trouble the number of software practioners that build software and have a PE. Most of them deal with software that interacts with machines, and not what runs in your computer, or web browser.
