<p>We recently had some behavior issues with our kids - they didn't want to do activities outside the house, they hated reading, they hated anything that required even the slightest discomfort or effort.<p>We decided to cut device usage way down - they get 1 hour in the morning to play whatever games they want on computer, tablet, console.  Then they get 1 hour before bed to watch TV.  The rest of the day, no devices.  We are homeschooled so this is a LOT of free time.<p>After a few weeks, they're now: blasting through books daily (to the point where they forgot their own TV time, which used to be sacred), playing board games with us more frequently, asking to do things outside like learning to ride bikes (which they've previously shied away from), writing their own comic books and board games on paper, and overall just being creative through the day and entertaining themselves.<p>It's such a huge difference.  It is the devices.  It's 100% the devices.</p>

<p>Big relief for me.  As a passive investor, I want the indices to follow the same passive strategy they always have, and specifically not make exceptions for specific companies like SpaceX wanted.<p>Plenty of ways to get exposure to that stock without it going into the indices it is not qualified for.</p>

<p>My son is in 4th grade (nominally anyway, we homeschool so it doesn't really matter).  He takes the MAP test periodically, which scores on a single scale for all grades.  You can look up the percentile score for your student's grade, as well as where that score sits on the percentiles for all other grades.<p>He's ahead in some areas, having some skills from as far as 7th grade, but mostly he's more in the 5th grade band by now.  His MAP test score is 50th percentile for 12th grade.  This means, basically, he knows more math than 50% of 12th graders who take the MAP test.<p>This really blew my mind at first, but these kinds of single-scale tests are really valuable for this purpose.  We should be reaching for a solid absolute standard, not grading everything on a curve and passing people who haven't demonstrated real mastery.</p>

<p>Hate to break it to you but the Mormon belt extends well up into Idaho (probably all the way to Montana on the East side) and down into Arizona, and diffuses out quite far from there.  Probably need to go through Montana or skirt the Mexican border areas to avoid it, but border areas these days come with their own issues self created by our government...<p>I lived in Idaho Falls (well within the majority Mormon area that extends farther North at least to Rexburg) and never had an issue, but I definitely knew I was not part of the club.</p>

<p>I don't know that local control is an unalloyed good. The interstate highway system would never have been built if we followed this as a principle, for example. For another example, Californian voters consistently vote for state level increases in housing, yet locally consistently vote against increasing housing in their community.<p>At some point national and state level goals must supercede local control if progress is to ever be made.</p>

<p>Even being social engineering, the design of the plugin system allowing this means the platform is completely unusable as a sharing tool.

<p>I spend a lot of time in the rural Philippines and I notice that locals out here don't sleep that well and it doesn't seem to bother them.  They get up extremely early with the sun, roosters are crowing even before that, cats are fighting randomly through the night, storms kick up many nights in the area through the year, and then they sometimes stay up late singing karaoke, though most of the time they are in bed early.<p>In compensation I noticed they nap frequently in the day time, often in the hottest part of the day when it's unpleasant to work.<p>It put my own sleep issues in perspective, I realized I had been a little too precious about it and I can indeed do fine on more fractured sleep. Often I form a judgment in the morning about my sleep and if I feel bad about it, I carry that through the day. I'm more convinced now it's a psychosomatic thing, I'm convincing myself I should be tired! So I try not to do that now and think of the people out here who live every day like this.</p>

<p>Also just as a follow on my assumption is it's much easier and cheaper to scale the DC side since it's often at the 400-500v range (for example 10 panels in series with open circuit voltage of 49v and operating voltage around 43v) vs the AC side in the 230v range, since resulting amperage is half. So that may account for the ratio.</p>

<p>Nope but in a different market so makes sense, those are probably pure grid tie inverters, which I don't have a lot of experience with because it's not commonly used here. I do see the EG4 hybrid has a similar ratio (we have the same tech here under the Luxpowertek brand).<p>Even without a battery people usually choose hybrid, which can function on and off grid.<p>Also to be honest I'm mostly looking at larger inverters so maybe that colors it. Not many users here need 24,000 watts continuous outside a commercial context, for instance, so an inverter with that as an input but 12,000 watts continuous AC output doesn't seem weird since part of the 24,000 watts DC can be sent to the battery.</p>

<p>Typical hybrid inverters have an output rating around half the theoretical max input of the panels. This is due to theoretical max of panel input being very rare or even impossible in normal earth conditions, the presence of an attached battery to soak up part of the input, and the general cost benefit trade off of solar equipment (more throughput means more heat, means bigger heatsinks, means heavier and more expensive).<p>You can definitely get equipment that can do symmetrical input/output, but if you actually model out the supply and demand curves on the system it's not usually going to be worth the extra up front expense since peak input is a small portion of the day and that extra hardware will mostly sit idle.<p>For that matter people often design systems where peak input can't even be accepted by the inverter and the extra power is just wasted, because it's more valuable to have a steady input over a long period than to maximize the daily peak.</p>

<p>This assumes you have more valuable ideas than you can implement. Which, at first glance, seems like something you can take for granted. But in my career over 15 years I was surprised to find it's not the case for most established businesses. The existing business acts as a constraint that limits the idea space way down, and the ability for owners and product managers to generate ideas is way lower than I ever expected.<p>Execution of unrelated ideas seems like a natural follow on, and having managed several such "labs" efforts, it's actually a good idea but it inevitably grinds up against the lack of will to continue investing in the face of headwinds, especially since the main business line is several orders of magnitude larger than anything labs can deliver in a foreseeable timeframe.</p>

<p>The next obvious question is where do they come from since presumably there weren't dinosaurs and plants dying there 300 million years ago.<p>Went on a bit of a rabbit hole and it appears that there is a lot of methane in the atmosphere and that gets broken down via photolysis into hydrocarbons somehow, and the methane likely is there from the formation of the moon originally via methane ice.</p>

<p>I love this idea and it's one of those ideas I categorize into the bucket of "when all the other lower hanging fruit has been picked", just because it's more complicated.<p>When we've got actually braindead policy like ethanol fuel mandates, the ROI of switching a corn farm to solar is so incredibly high that solutions like this just aren't competitive.<p>I wish some of our billionaire class would turn their attention to these things rather than building yet another rocket company. Maybe that's why Gates is buying up farmland, who knows.</p>

<p>Same in the Philippines here, and we're all buying the same Chinese materials at the end of the day so somehow Americans are getting really fleeced hard on this equipment.<p>Payback time is 2-4 years.<p>It reminds of healthcare and infrastructure in the US. When you really dig into why both are so expensive, it's literally every step. Every link in the chain between supplier and consumer is some kind of inefficient market, or burdened by regulations, etc.<p>Americans are just so rich they don't care enough to see these huge margins and undercut the competition, which is what happens here and keeps markets much more efficient.</p>
