Saudis parked fuckload of money in ai startups

This will continue as long as there are CCGTs used as baseload, then it will drop as CCGTs (and biomass + waste burners) will cover the gaps

methane cracker? that’s a very unusual unit that outputs hydrogen and carbon. i could find info about opening of ethane cracker in 2025, but that’s for plastics, next to shutdown of another similar unit

No they don’t, there’s still 4 units one per launcher. Most of problems you mention seems to come from energy storage system. Energy is stored in the flywheels, which requires annoying converter, so chinese variant uses giant set of supercapacitors instead which is just a bit heavier and has less problems with communications interference. Also can be split in many parts and fit in any space you have. Mostly benefit of being designed later. Zero surprises if americans figure it’s better but institutional inertia keeps them using the old one

They don’t actually. Steam catapult is operated with completely separate steam supply, and major design goal of ford class was to remove it so even if pedo in chief wanted, retrofit is physically impossible. That separate steam supply needs extra freshwater because it’s not condensed and recovered. EMALS is much milder on plane and pilot because it’s a big linear motor that gives constant acceleration instead of spike then decreasing like with steam. Efficiency of steam catapult is also dogshit compared to turbine + energy storage system

EMALS has been around for over 15 years so naturally trump lost interest

there are photos of 16 different radios and a couple of antennas, but the one in thumbnail is Elecraft KH-1

It’s up for you to decide. On U/VHF you can talk to other people directly (locally) like on HF. But you can also do things that HF can’t provide, or provides with limitations, like talk through repeater (uncommon on HF), or to ISS, or through satellites (HF bounces from ionosphere) or do longer distance communications from mountaintops, or do image transmission or packet radio (HF has less bandwidth). On receive only you can also download NOAA weather satellite images, or whatever else data are emitted by them. You can make your own repeater from two baofengs. HF gets affected by space weather, U/VHF is not, and we’re entering solar minimum. 6m will take you far further than 2m but it’s usually bundled with HF radios

On higher end there’s also moonbounce, but it’s not in the budget category

e: there’s 50 things you can do with SDR only (many on U/VHF) https://blinry.org/50-things-with-sdr/

Depends on what you want to do. UHF/VHF handheld radio can be had for 20-30, uSDX or QMX type small low power HF radio is closer to 100. You’ll also need battery, antennas (perhaps tuner) and something to put data in and out (headphones and microphone or cw key or audio interface to laptop) (no idea if it’s good but people use it)

You can’t critihype it when you call it phage madlibs from the beginning

waaaaay less impressive when you take a look inside

Once Evo got familiar with the genomes of Phi X-174 and its kin, the researchers prompted the model to write new versions of its own. Evo generated 700,000 potential versions; the scientists pursued only the ones that looked as if they had the best odds of succeeding.

They ended up making DNA molecules from 285 of Evo’s suggested sequences. […] All told, they discovered that 16 of Evo’s genomes produced viable new viruses.

Dr. Crook cautioned that Evo’s viruses were not radically new creations. They tend to be very similar to natural species, relying on the same underlying biology.

look out for breathless boosters “warning” everyone that ai will kill us all and it’s definitely not used as a marketing strategy

that bot setting is just irl evil bit

hornyposting on main must be one of these elusive family values then i guess

there are still coal powerplants around and any replacement is better. geothermal doesn’t work everywhere

Coal ash (from some mines) contains so much uranium that if emissions like this were detected near NPP all hell would break loose, but nobody cares. Energy content of that uranium can be higher than what was released during coal combustion

it replaces gas turbine with a fuel cell, which is a good couple % more efficient than CCGT. still under development. there is also another variant where hot offgas is generated under pressure and expanded directly. no steam, same effect

Could be. Amplifiers are a bit more complicated and there are many things that can limit bandwidth

there is a power generation scheme that uses high temperature fuel cells. optimally it could run on hydrogen only, but because it runs hot, it is able to take almost any flammable gas, along with some steam, and it forms hydrogen internally, then oxidizes it. this alone generates bulk of electricity, but offgas is hot, so it goes to heat exchanger which boils water, which then turns steam turbine

If we consider groundplane antenna, which should be much better than anything that you can fit on a HT, it might be centered on 145MHz (region 2 band) and it’ll be good for 10MHz for 1:1.5 SWR (140-150) and 17MHz for 1:2 SWR (136.5-153.5) according to some random measurement, first that i found. Outside of these ranges SWR rises rapidly and if you tried to transmit on say 170MHz you might get SWR 1:5, perhaps 1:10 or worse if you’re unlucky. On receive this doesn’t matter too much because these nano- to microwatts of rx power would just bounce back harmlessly with the only effect being that apparent signal strength is lower. But if you tried to transmit then design currents or voltages would be exceeded and something will break, usually final stage of amplifier. This gets rarer than it used to be because some radios can measure SWR and will reduce power in such scenario. This also gets worse the higher transmitted power is

This happens because unlike on HF + 6m, on 2m and up ATUs are not a thing* and all antennas are expected to be matched. So you can use the same radio on GMRS or PMR or what have you and on 2m or 70cm band, but you have to change antennas between these uses. If you want to use all of these on one antenna, then there are special wideband designs like LPDA but this makes sense on a mast and not on handheld radio

* there are tuner designs that work on 2m and up, but you won’t find them in HT, there’s no point, they’re too big, too heavy and too expensive

Even if you tried and made it to work, there might be other incredible problems with things like harmonics or other spurious emissions because filters were not designed to work way out of these frequencies. For example you can try to force Quansheng UV-5K (?) to transmit on 60-ish MHz but most of the power goes out at 2nd and 3rd harmonic, because of the way filters were set up. Narrowband designs are much easier and this is what you’ll see all the time in amateur radio. Wideband and ultrawideband designs are constant source of job security for RF/microwave engineers

You can think of matching units and antennas (and to some degree even feedlines) as filters to some degree, because their bandwidth is not infinite
