  1. Re:Solar thermal scales better on Largest US Power Storing Solar Array Goes Live · · Score: 1

    The $7/watt figure here includes storage of 6 hours at maximum output. So for a 300 watt PV panel, exactly what is the fully installed and warrantied price of each 1.8KWh battery pack, including a 30+ year warranty at 365*100% discharge cycles/yr?

    The answer is "irrelevant" because we're not within a factor of 100 of having more solar energy online than we can use in real time. The only people who back their PV with battery systems are 1) fools willing to pay a fortune for the privilege of thinking they're giving the utility company "the finger", and 2) people who absolutely can't get a grid connection (and are thus paying a fortune for their battery-backed PV).

    It's also "irrelevant with prejudice" because the $7/watt thermal plant in question most obviously does not come with a 30-year warranty either. In fact, no one seems to want to talk about its operating costs, which are probably staggering.

    Hmm, maybe you should think before speaking next time.

    I'm thinking and typing. And you're acting like an asshole in public.

    Make it bigger and those costs come down.

    How much and by what means? It's pretty well accepted that PV will be at $2/watt in 3-4 years. Thermal needs at least a 4x improvement in power/$ to be even worth considering unless it provides some unique benefits. (Storage is not one of them--we're not within a factor of 100 of having more solar online than we can use in real time.)

    It's not big but it's big enough for a proof of concept.

    And at three square miles it's not exactly small, either. PV has the advantage of being arbitrarily scalable, and not requiring dedicated land, which means it can be sited closer to the point of use.

    So in other words this thing makes perfect sense and bitching about it [...]

    It might make sense under some very specific criteria, but that is far from conclusively established. And using the brain for critical thinking and asking reasonable questions is not "bitching".

    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.

  5. It's worth investing effort... on What Are the Genuinely Useful Ideas In Programming? · · Score: 1

    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.

    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).

    This is conflating unrelated things (internal combustion holdouts with "cloud connecteness" and other user interface aspects).

    Electric drive is coming, like it or not, and it's a great thing. As for the other, there are good and bad ways to execute, and it's healthy to be wary of change.
