Comment Re:6 hours? (Score 1) 377

Base load is the easy stuff in power generation. The peaks are vastly greater than the minimum demand at night.

Absolutely. The whole thing about the sun not shining at night is a total red herring, because that's not a problem until the day we produce more solar energy than we can use in real time, and we're a couple orders of magnitude away from that good problem too have.

PV does not scale well since if you double the size you only double the output. With thermal solutions of all types you can get a lot more heat out of stuff if you have a lot of hot stuff

No, not really. The energy available is directly proportional to the collector area, be it PV or thermal.

Besides, installed PV is around $4/watt (and falling fast), while this thermal plant was over $7/watt.

Comment It's worth investing effort... (Score 1) 598

Code that's successful tends to last a lot longer than its creators anticipated, so lay that foundation carefully. It's usually worth investing effort to do it as right as possible the first time. Doing it "quick and dirty" is the equivalent of mailing somebody a bomb, and often the recipient of that bomb will be you.

That said, there are some fantastic programmers in the quick-n-dirty catagory. Use them effectively--to throw together proofs of concept and demos, to explore alternate implementations, etc. Just don't let them manage the whole damn project.

As the codebase gets larger and older, collecting dependencies along the way, it gets exponentially more expensive to redesign/rework components. Sometimes those are the only good ways to fix bugs, so you'll end up with not-so-good band-aid fixes instead. Then, your technical debt is growing exponentially along with your codebase.

Why are we paying $4500 a year to get worse results than 20-30 other countries including many 1st world countries with otherwise similar costs of living?

Just for the record, Americans actually spend nearly $9000 per capita per year on health care (without actually covering everyone, of course). The $4500 you claimed would be an enormous improvement, but still worse than the UK, which spends about $3000/year, and actually covers everyone in the process.

IAAEVE (I am an electric vehicle engineer) and I worked on Li cell, battery, and powertrain technology that was licensed to Tesla.

The real problem is that nobody's allowed to make big batteries for use in cars because the oil companies bought up all the patents

Please stop spreading this BS rumor--it's been floating around the "EV community" for long enough, and it's totally untrue.

Anyone can license those patents, and no, Chevron's not going to build you any unless you want a LOT of them, but it doesn't even matter: No one wants to build NiMH cars anyway, because we have much better cells (Li-ion) now. Even hybrids, which need power (more so than energy) and were the last NiMH holdouts have moved to Lithium.

This is the reason they have to use 8000 tiny little flashlight batteries in cars instead of a few dozen big ones.

This is wrong in so many ways it makes my head hurt. First, you're confusing radically-different cell chemistires (NiMH vs. Li-ion). Second, the "flashlight" cells are actually 18650 Li cells, a form factor often used in notebook computers. Lastly, Telsa uses 18650 cells because they are (by a large margin) the best available in terms of energy density [Wh/kg]. If you want heavier or more expensive cells, there are plenty to choose from.

Untill the world gets its act together and starts deploying more CANDU type reactors which by design cannot meltdown, I for one will still fight against nuclear power.

The right time to fight against nuclear power is the day after the last coal plant shuts down, because back in the real world, when nuclear shuts down, coal replaces it (immediately!) nearly 1 for 1, and coal kills many, many more people even when it is working nominally. (Coal generation also releases much more radiation into the atmosphere.)

Alternative energy proponents: Save it. I love 'em, too, and I back that up with the 7 kW of thermal and photovoltaics on my roof, but it doesn't change the fact that coal (and gas) are what ramp up (in real time) when nukes shut down. Examples abound.

Germany? Building new coal plants as it blathers about shutting down the nukes.

Japan? Partially made up for their nuclear shortfall with conservation (good!) but mostly with increased imports of coal (and especially LNG, brought to you by fracking).

Now that the last San Onofre units are offline, California will be compensating (forever) with additional coal and natural gas generation.

The people didn't ask for any of this. Those in power were merely opportunists willing to exploit a tragedy in order to expand the powers of government past their legally mandated boundaries.

Calling the end result "the will of the people" is just nonsense.

Why? On balance that's what it is.

Perhaps "the people" didn't ask for it directly, but for the most part they're delighted with the outcome. You and I may not like it, but an overwhelming majority of americans approve of the naked body scanners and other invasive TSA practices, and there has been no meaningful backlash against illegal wiretapping, GITMO, "papers please" travel restrictions, etc.

A nation of fools (who would trade liberty for the illusion of security) deserves at least as much blame as any of "those in power" who took advantage.

Comment Texas to California, seriously? (Score 1) 98

Until there really is a super-charger network from central Texas to California, I wish I could get one of the gas-powered (or gas-electric hybrid) Apteras.

If you're really making the Texas -> California road trip often enough that it's not an outlier, then an electric vehicle is not the right vehicle for you even if Tesla's Supercharger network (which is proprietary to Tesla, BTW) comes to fruition. The good news is that the (in)ability to make outlier trips like that doesn't have much bearing on the utility of EVs for the 3-4 standard deviations of driving that we do.

Comment Dealers are right to feel threatened... (Score 1) 555

Being an industry insider, I'm sometimes a little rough on Tesla, but if there's one reason I'm rooting for them, it's because I want someone to lay waste to the antiquated car dealer model in place in the US.

I just went into a [shall remain nameless] dealer over the weekend for the first time in a decade, and I'd forgotten how absolutely awful it is.

Comment 1 vs. 2 hands (Score 1) 260

I do some things (like write) left handed, but use my right hand for other things (e.g. I bat right handed). For years I searched for the factors that made any given activity a left- or right-handed one, until a few years ago when I finally noticed the pattern.

I do single-handed activities left handed, and two-handed things the way a typical right-handed person would. Tennis is a left-handed thing, but a two-handed bat (or golf club) grip makes me a righty, there. A fork goes in the left hand (which makes me Euro-compatible) but scissors go in the right hand. (I think it's a two-handed activity because you manipulate the cut material with the other hand.)

And since everyone else is weighing in on this: I'm not a regular firearms user, but a one-handed weapon definitely goes in the left, while I'd hold a rifle right-handed.

And I'm posting this in hopes of discovering if there's anyone else out there like this.
