    Getting the extra power isn't a problem. Dissipating it effectively is. 280 watts is a lot of power to get rid of. You need a massive heat sink and great airflow, or liquid cooling.

    The market won't support solar panels with a life of only 5 to 7 years. Half the cost of solar is the installation. If you have to put in new panels every 5 to 7 years the economics don't work out. While the problems mentioned exist, they can be mitigated designing panels with longer life. We...

    Bathroom fan replacement (v. quieter + more CFM)

    We only have one bathroom and it doesn't have a fan. I always thought fans were a thing if you had a windowless bathroom. We have a bathroom window, and if it gets :poop: , we can open it and turn on the whole house attic fan.

    DJI drones - New Mavic 2 pro announced tomorrow

    That all may be true, but look where they're testing it. It's probably miles from anybody but the people testing it. I also don't think it would fall a whole lot faster even not autorotating. It's light with a fairly large surface area. I'd be surprised if its terminal velocity at lower...

    DJI drones - New Mavic 2 pro announced tomorrow

    I've read it's possible to get waivers but that's probably beyond the means of hobbyists. Companies like Blue Origin have to get waivers to launch their rockets, for example. It looks like there are no rules regarding height in Mexico, so that's one possibility...

    DJI drones - New Mavic 2 pro announced tomorrow

    Those are my thoughts exactly, Doug. I would love to try something like this but it's obviously not happening in NYC, or probably anywhere in the NY Metro area, for obvious reasons. My parents bought a plot of land in New Mexico. It's pretty much in the middle of nowhere. The area was supposedly...

    DJI drones - New Mavic 2 pro announced tomorrow

    You can see the ascent/descent rate in the info screen (middle right just under the altitude). It looks like it maxed at around 37 m/s (83 mph) for the 33,000 foot flight and about 48 m/s (107 mph) for the 40,000+ foot flight. That slows a lot as you descend into thicker air. The propellers...

    Express elevator going up, way up: Record drone flight to over 33,000 feet Later record to 40,000+ feet As far as I know, it's completely legal to go this high with drones in the area where these flights were made (Western Siberia).

    Add about 50°F to 100°F to those numbers once global warming runs its course. If I live long enough I might actually see 200°F broken somewhere on the Earth's surface.

    Honestly, when I was researching solar panels it was kind of a shock to me that by default you won't have power if the grid was down. One of the reasons, albeit a minor one, for getting solar panels is exactly so you have power during blackouts. The fix is relatively simple, namely to have a...

    Or just get a Ryzen 2400G APU for about $136. If you don't want a gaming PC, you likely won't notice the difference between 4 cores/8 threads and 6 cores/12 threads. The IGP on the Ryzen is superior to anything from Intel. In fact, nowadays if you don't want a gaming PC I'm not seeing much...

    The price sounds in line with what other places charge. One thing everyone should do before installing solar is see where usage can be reduced. We went from an average of around 1000 kW-hr/month to 670 and dropping (I'll know the exact figure as soon as the cooling season is over). How did we do...

    I'll need to check if ConEd does something similar, although the way I'm sizing my system it probably wouldn't generate a net surplus beyond my annual average usage. That makes sense from the perspective you mentioned, plus micro-inverters already have all the other advantages I mentioned. The...

    A 6 or 7 kW system should probably cover that in your part of the country. Covering your needs is ideal but anyone know about the situation where you generate more power than you use? Does the power company buy that power from you at the going rate they charge you, or can the best you do with...

    Ancient PC with Windows 98

    Also, a lot of master/slave support was flaky at best. Some devices worked fine alone but didn't work once you added a slave. Others worked fine as masters, whether alone or with a slave, but didn't work at all as slaves. It's only safe to say the drive doesn't work at all if it's set as a...

    A lot of employers explicitly prohibit moonlighting because of its effect on job performance. In some places it's even illegal to moonlight. Even if not, there's a lot of legal stuff to worry about: https://www.nurse.com/blog/2018/01/22/dont-land-in-legal-hot-water-when-moonlighting/...

    Best 8TB Drive

    Obviously if you need that much storage SSDs will cost many thousands more. I couldn't imagine filling up 8TB, never mind the amount of storage you have. For the masses who can probably get by with 1 TB or less, SSDs are the best solution. I'm pretty sure he's still alive even though he stopped...

    Best 8TB Drive

    Don't know anything about quality but 5400 or 5900 RPM 8 TB seems to be the sweet spot in terms of cost per TB. I don't see much point spending more for 7200 RPM when the decrease in access times is marginal, and 8 TB will most likely be used for bulk storage. In my opinion, given the high bit...

    Technically speaking, "throttle" more accurately describes the function as it's something which varies the power output of the engine or electric motor. "Accelerator" is really a slang term. If the term were strictly accurate, you would only hit the accelerator to accelerate. When you let off...

    I personally think of retirement as a time when I can just do only work which I find interesting and which pays enough, rather than taking anything which comes my way. I really have no set age when I'll just never take any work. So long as the mind/body are able, and the work is enjoyable, why...

    Earnings potential doesn't necessarily mean much at this point. Yes, I was making about $100K annually on my last consulting gig but they no longer need me.

    I've been doing asset planning for a long time. Basically, I'll have way too much assets to qualify for Medicaid when I'm over 65. I can technically get Medicaid right now since there is no asset limit if you're under 65 but then that means if any lucrative consulting work comes if I'll have to...

    Well, if I had coverage I would have had it treated. For what it's worth, for a lot of relatively minor stuff, the Internet is a great source of information.

    Here's the thing. Nobody knows what the healthcare landscape in this country will look like in even 5 years.

    I've probably spent $15K on dentists over my entire adult life. Yes, it's a big hit when you need work, but it doesn't happen often.

    The problem is neither of them drove all that frequently. It was mostly short local trips. As a result, their driving skills weren't that great to start with, especially my mother, and got worse due to the problems with age. In the case of my mother, she had joint and other issues which...

    I've paid out of pocket for the dentist. It's not that bad. Getting coverage for something like that is pointless when the premiums will likely exceed what you get in dental bills.

    Yes, very true but at least the pilot is capable of safely flying the aircraft should the autopilot fail.

    Right, they're a work in progress. They're not ready prime time now, but probably in 5 to 10 years they should be.

    It's not a question of wants. It's a question of what people can afford. Lots of people I now can't afford a new car, or even a relatively new used car.

    Sure, something designed from the ground up as an electric is going to be better but conversions are certainly feasible. People are already doing it. Another problem is have you seen the new car choices? It's really more like new SUV, pickup, and crossover choices. If you like real cars, as...

    Last I checked fewer and fewer people have money to buy new cars. There's also a demographic shift. But my point here is today's car bodies last a really long time. If someone is happy with their vehicle, why wouldn't they want to convert it to electric, instead of taking chances buying...

    That might not be a bad business to be in. There will be a combination of carrot/stick approaches to get ICEs off the road.

    No one wants over 16TB per drive SSDs

    It's probably more complex than that. The failure of an SSD is some function of the failure rates of the controller and the individual NAND chips. Since drives in any given generation use similar density NAND chips, an individual NAND chip is not more likely to fail based on the size of the...

    No one wants over 16TB per drive SSDs

    In the case of SSDs, unlike HDDs, it's not like the larger ones have higher data density. They just have more NAND chips. I have more confidence in SSDs since we've increased chip capacity by stacking cells, instead of using smaller cells. The primary problem with large SSDs is when they fail...

    No one wants over 16TB per drive SSDs

    I can say as an individual I probably wouldn't want anything much over 4TB. The problem is backing it up. Some SSDs suffer from a data retention problem if left sitting unpowered for long periods. HDDs in my opinion have squeezed so much data on a platter that they're inherently unreliable, period.

    I did something like this maybe 15 years ago when I ran ethernet cables from my bedroom to four other areas. What helped was routing them partway either through the attic or the basement. That meant I just had to either drill a hole in the basement ceiling where the cable would drop down from...
