I have been using Brave Search for the last half year, results seem to be better than DDG and you can append g! to your searches like DDG for Google results.
hellgas00··on How can we make air conditioners more efficient? [video]
LG uses linear compressors in their fridges, very similar to this design and they have been out for years. They generally fail after only a few years, terrible reliability in comparison to a piston compressor.
hellgas00··on Facebook suppressed report that made it look bad
That's not exactly what the article you post says;

"Dr. Gregory Michael’s official cause of death stemmed from complications with immune thrombocytopenia, or ITP, a blood disorder caused by an immune reaction, after getting the Pfizer vaccine, the Miami-Dade County Medical Examiner Department said."

"The idealistic future is one with much more censorship"

Hopefully this can be made into a bumper sticker.

Divide and conquer, as old as politics and war. In this case, populist resentment is the obstacle.

They mention steam in their demo video drives the primary pistons, which in turn drives a 2nd set of pistons that contour a liquid metal chamber, which in turn compresses the fuel mixture.

hellgas00··on YouTube bans Steve Bannon's podcast channel
It should be, but it's not, that is what this discussion is about. The band are political in nature, not moral.
hellgas00··on YouTube bans Steve Bannon's podcast channel
This is the crux of it all. Spend a second to think critically about what is going on outside of the news media echo chamber and it becomes apparent it's not about a moral stance, it's about controlling narratives and exerting power against their political enemies.

Do you remember Russiagate? How half the country literally believed that Trump was a puppet of Russia, and that Russia had hacked the election. Hilary Clinton wrote a book about it. I will say that Trump should act with more tact and decorum, but just months ago CHAZ was a literal autonomous zone acting outside of the laws and authority of the city of Seattle. Nobody should have had their ability to communicate freely online taken away because of it, but fascists apply mental gymnastics to affirm one moral stance against another depending on the person commiting the crime.

Watch speech Bannon gave at The Oxford Union Society if you want to genuinely understand the arguments he makes. I think you'd be hard pressed not to find some of the points he makes compelling.
hellgas00··on OPSEC critique of the Michigan Governor kidnap plot
On Friday, the Washington Post profiled several members of the group.

"One of alleged plotters, 23-year-old Daniel Harris, attended a Black Lives Matter protest in June, telling the Oakland County Times he was upset about the killing of George Floyd and police violence."

Another alleged plotter, Brandon Caserta, called President Trump a 'tyrant' - adding 'Trump is not your friend, dude.' Caserta notably has an anarchist flag behind him in several videos he's recorded.

hellgas00··on How the Maker of TurboTax Fought Free, Simple Tax Filing (2013)
It works the other way around as well. The left votes for social issues that upset the established cultural state, and which in the grand scheme of things will have minimal real impact (like transgender people using any specific bathroom). Social issues are a dividing force that occupies both sides of the spectrum, it's conveniently used as a means to divide and conquer. It's why most politicians will take on social issues as their political battle cry and shy away from issues that will impact financial markets. It's easier if you don't bite the hand that feeds you (wealthy donors).
hellgas00··on “AppleMusic will pay artist for streaming during customer’s free trial period”
NSA was spying on people for years before it was made public, tens of thousands of people had managed to keep their mouths shut. Collusion is a thing that happens all of the time, and considering the money involved its bound to happen again.
hellgas00··on Greece’s Proposals to End the Crisis
It also destroys confidence within countries that are near the brink of collapse, why would I invest in a country that has an unstable future, is what credit markets would be thinking. As well, the debt of Greece has been restructured in light of their financial issues so that the ECB and IMF hold the majority of Greek bonds, have the other faltering countries had their debt restructured? If not that could be an issue going forward. Would the collapse of one country lead to financial contagion? Germany has gained quite a bit from being a part of the Euro, they would also stand to lose a lot from the dissolution of it.
hellgas00··on Solar Power Battle Puts Hawaii at Forefront of Worldwide Changes
I pay about $150/mth on electricity ($1800/yr), if your numbers are to be believed, then it would take about ~13.2 years to pay off a 24k battery pack, this doesn't include the cost of the panels which would probably be another 24K, so roughly a 26 years to pay off (Probably the working life of the panels) So basically at current prices the cost is on par with my utility. It's not amazing, but with the right gov't incentives and future advancements in battery and solar technology I don't see why we couldn't see renewables edge out the dominant players. Sucks for me though, just finished my B.eng in mechanical with specialization in thermal power generation.
hellgas00··on The decline of Vancouver
If only humans were robots without emotional attachments, family or a desire for happiness, applying market solutions to problems would be so easy! Being priced out of the city you grew up in because foreign investors are looking for a place to hide money safely is not good for a city in the long run, or its inhabitants. Perhaps more stringent foreign ownership rules could be applied and produces an effect that didn't require the next generation to pack up and leave for greener pastures.
hellgas00··on The US government's web traffic
What's the point of this comment, all you're doing is trivializing how people use government websites/programs. Also there is absolutely no way your effective tax rate is near 40% unless you're in the 99th+ percentile of earners, a little melodramatic, no?
hellgas00··on Too much finance is bad for the economy
H igh risk endeavors in science are worth the risk because when they pay off they may shift the way we have been doing things in the past, which leads to unforeseen opportunities in the future. This is not an insightful thought, but I believe it is usually overlooked.

The British Engineer Charles Babbage (Father of the Computer in many respects) wasn't afforded the opportunity to complete the first working mechanical calculator because of cost restrictions by the British Gov't, an invention which could have altered the British course in History. High risk projects in Science and Engineering may rarely pay off, but when they do the ROI is incalculable in many ways. Flipping houses, not so much.

Curing cancer is a place holder for any number of fields that are still under-explored. Finance really shouldn't be a driver of growth, especially when the growth is concentrated in public financing of debt, it just doesn't seem sustainable.

hellgas00··on “Equation Group” ran the most advanced hacking operation ever uncovered
-Just to point out, but Israel does not recognize and actively suppresses a state for the Palestinian people, and western nations like Canada support this religiously motivated move (Right wing Likud party and extreme right Jewish Home parties have no plans on ever recognizing a land for Palestinian people). You can't say that these actions are morally righteous while looking down your nose at Iran for doing the same thing.
hellgas00··on Rooftop solar is now cheaper than the grid in 42 American cities
Through out the day electricity demand fluctuates rapidly[1], talking about a 30-50% fluctuation between 6am and 6pm. I really don't understand your post, the need for reactive plants would still be needed (and used) without solar power generation. The limiting factor is to make sure that solar fits within the band between the baseline constant load and dispatch provider power. As long as Solar isn't forcing Nuclear plants (or whatever the baseline is in your area) to ramp, it isn't a big issue. Gas plants will ramp through out the day due to our usage patterns, regardless of solar production. Only way impact this is storage.

I've also seen people argue against solar because it means that plant will have to run at variable temperatures, meaning less efficiency. This is also not true because gas stations usually output around 200MW a piece, and when you have 10s of these plants scattered you can stagger their shutdowns, allowing power plant operates to run efficiently longer.

hellgas00··on RadioShack Prepares Bankruptcy Filing
You posted a website that lays out relevant electronic components supply stores in an easy to digest manner. The problem I see is that the average hobbyist might not know where to start without first knowing about that site.

For instance, I used to buy computer parts from BestBuy because it was easy, they were everywhere, and I didn't know about the smaller stores that were better priced and staffed with generally more knowledgeable staff. I knew about BestBuy because it had a large brand identity, and could market to the general population. RS was large enough to market their business stream to the general population, while these smaller stores can not.

When it comes to sourcing components, you are left to do the research if you want to buy from brick and mortar. If you want to buy a tablet or gaming console come to BestBuy because they told me they have everything.

I still think RS had a great model in hobby electronic, and I really think they could have developed that model, not only for their own financial gain, but to the betterment of society. I didn't find out about hobby electronics until I was in my late teens and more substantially early 20's studying Engineering, probably because it was never effectively marketed towards me.

hellgas00··on RadioShack Prepares Bankruptcy Filing
I live in Toronto, Canada where there are a bunch of independent stores that sell hobbyist electronics and seem to make a good profit doing so, so the market isn't dead. I like to buy stuff online but there have been plenty of times where I've been stuck needing a sensor, resistor, or things of that sort, and don't want to wait for 2 weeks for it to ship from China. It's a false premise to say that electronic component sales moved online when these isn't much in the way of a flagship brick and mortar location to purchase these goods. RS made a choice to move away from a potentially growing market, a market that they owned and could have expanded, and inevitably pushed their customers online.

Just my 2c, but I'm amazed that they thought they would move in on BestBuy (and FutureShop in Canada) territory and be able to compete.

hellgas00··on How Reddit Sparked a Dialogue Between Scientists and the General Public
Apparently the r/spacex community got together ahead of the AMA with Musk to come up with quality comments. During the AMA they worked together upvoting their questions to get the most visibility. The mods on r/AMA felt that this was against the rules, and crowded out the natural discussion, they subsequently deleted all posts from r/spacex. Sounds like a good idea, until you realize that they were very well thought out questions, head over heels better then the questions posed by the r/AMA community. I found the AMA to be underwhelming.
hellgas00··on To save money, state builds copters from surplus parts
Why waste good helicopter parts? I would have to think that the materials used in military applications are more robust than commercial. Refurbishing old parts isn't bad so long as it's done safely. The article says that the helicopter parts are inspected visually every 25hrs, a tear down is done every 125hrs, and any anomalous issue gets them grounded. No mention of problems with the refurbished copters.

Honestly, I think this is a very smart and efficient move on the part of the state. Reuse when possible, so long as it doesn't jeopardize safety.

hellgas00··on An Offer to Sony from 2600
I see what you are saying, but I would have to guess that it's so very rare that the authorities know for sure that a suspect has information to give, that it is almost irrelevant to debate the scenario.

Not to mention, the use of the ticking-time bomb scenarios were used to justify use of torture by the CIA. Which entity determines if a suspect has usable information, to stave off 'improper' use of torture? If you can't trust the CIA to make a definitive call in that regards, why even consider torture as an option in any form?

hellgas00··on An Offer to Sony from 2600
This is the case where there is without a doubt a definitive 'ticking time bomb'. Torture is usually used to illicit confessions, and in the case of the CIA they used it as a method to garner further information without knowing if the subject had more information to give. Say the guy in the article was just a suspect and didn't actually know where the person was, is it prudent to torture him because he might know something?
hellgas00··on Toyota Embraces Fuel-Cell Cars for Post-Gasoline Future
When I see proof of concept I will be less skeptical. As well this only solves conversion efficiency, batteries are already +85% for conversion efficiency.
hellgas00··on Toyota Embraces Fuel-Cell Cars for Post-Gasoline Future
Again how many stations exist? I'm not arguing the concept, I am arguing the feasibility. What is the cost for fueling at these stations? Solar panels generate electricity yet we don't use them to power industrial operations because solar expensive! Just like H2 from electrolysis won't be able to compete with industrial H2 production from coal. Also, what you're suggesting is using predominantly coal to generate electricity from a traditional plant (~40% eff), then transmitting the electricity to a station (90%), then creating H2(60%). Compare that to coal steam reformation (75%) and transportation (80%, being conservative), the latter is far more efficient and cheaper.

And what infrastructure do you need? A gas truck with a pressurized tank on it. The cost of hydrocarbon based h2 will displace electrolysis in large scale production.

And your last point about distributed load efficiency gains, electric cars are already able to balance load and feed into a grid. It's always going to come down to cost, I'm going to buy the cheapest h2 around and it's going to come from steam reformed coal.

hellgas00··on Toyota Embraces Fuel-Cell Cars for Post-Gasoline Future
You need to pressurize the hydrogen to 5-10 kpsi which requires a compressor in every home, this cuts efficiency. Electrolysis is also very inefficient (%65 is usually cities as the upper efficiency[1]). Most importantly the cheapest way to produce hydrogen is through stream reformation of Carbon based fuel (high CO2 emissions req), making electrolysis cost prohibitive.

Hydrogen is not a great way to go, especially when you consider that batteries and electric motors are already very efficient. Working on energy density in batteries would be more cost effective then chasing after H2.
