Meanwhile, all of the tech equipment purchasing supporting those activities has come to a grinding halt.
I leave mine in the aquarium, safely out of reach from the kids.
On the other hand, why would you bury the charcoal? There's lots of demand for it. Then we can stop doing whatever we're doing for charcoal now, which is obviously less efficient since we're not capturing the gases, and probably aren't using direct solar thermal.
Right now I believe most is made from waste wood from lumber factories. They do a low-oxygen burn in charcoal sheds. It doesn't seem efficient, but it is more efficient than turning perfectly good lumber straight to charcoal.
And.. innovative?? Innovation? Involving fossil fuels? The only trade secrets they are likely protecting is the toxicity and environmental impact of fracking.
You don't know what you're talking about. There are a lot of trade secrets in fracking. There are trade secrets in the instruments that monitor and improve drilling. There are a lot of trade secrets developed to improve production efficiency. There's a lot of essentially "public" knowledge too, but even that is hard to come by, so internal training materials can be extremely valuable to capture that knowledge that is typically only accrued with experience or being an insider at a reputable company. Just because fossil fuels have been down there a long time doesn't mean there is no innovation involved in getting them, otherwise we (the USA) wouldn't have just passed up Saudi Arabia as the worlds biggest energy producer. American fracturing companies dominate the world market for fracturing.
China has a problem trying to exploit its shale reserves. They aren't as flat and even as those in the USA. So they may be looking for ways to make similar improvements exploiting their own shale reserves by looking at how we fracture reserves in states that do have some geological variance in their shale reserves, like Pennsylvania and Colorado. Chinese companies are making often pitiful attempts to compete in the international market with sub-par technology. It won't always be pitiful though, I think. They're obviously trying to improve and the only thing holding them back is the trade secrets.
But precisely finishing the last 20 percent of a lower receiver has still required access to a milling machine that typically costs tens of thousands of dollars.
Whatever. I made mine with a $350 micro milling machine from Harbor Freight. The template kit to mill & drill the other 20% of the incomplete lower receiver was about the same cost as the 80% complete lower receiver. So all of the parts & tooling in sum total less than $550. Plus I use the mill for other things and the template has resale value. Also FTA:
Defense Distributedâ(TM)s machine canâ(TM)t carve pieces as large as its competitors, but its small size makes it more rigid and precise, allowing it to cut an aluminum lower receiver from an 80 percent lower in around an hour. Thatâ(TM)s a task Wilson says would still be impossible with todayâ(TM)s cheapest hobbyist mills but doesnâ(TM)t require five-figure professional tools. âoeWeâ(TM)re making this easier by an order of magnitude,â he says.
I think that they meant to quote him as saying it is POSSIBLE. An order of magnitude is a gross overstatement, given that this was the 3d milling version of trace paper.
Subversive ambitions aside, Wilson doesnâ(TM)t hide the fact that the Ghost Gunner is also a money-making project.
For that matter, oil floats on top of water, so how does the lower 99% get contaminated? If somehow a gallon of oil was mixed into water in such a way that every molecule of oil was separate, and each molecule floated 7 inches from any other one, how many gallons would be contaminated by that oil?
All of them. Remember that when the fluid comes out of the well, there is gas, water and oil in one turbulent, bubbly stream. The separation process is relatively simple and doesn't include any filtering really. It's basically a settling process with some baffling to slow the turbulence. The oil and water in the beginning are quite well mixed from turbulence and so on. Lots of stuff that makes oil black can dissolve in water better than it can dissolve in oil, so produced water is really nasty, caustic stuff and varies from clear to black. Depending on the locale it can even eat through stainless steel sometimes. Oil contamination is not the biggest issue, but due to soaps used for lifting the fluid it may have some dispersion, regardless of the other chemicals often pumped down there specifically to separate the oil and water. A typical oil loss to water might be 0.001% if the process is fine tuned and the separation equipment is appropriately sized, or worse if it's not (which it usually isn't in the beginning).
I work on safety systems to prevent these kinds of accidents. By law these tanks have a berm around them to capture the leaked fluid if they are permanently installed, temporary vessels may not, so I'm guessing this was a temporary vessel like a frac tank (looks like a big shipping container). The plug they're referring to is most likely a 1/2" or 1/4" NPT plug where a level gauge or fluid level controller would be installed. They are usually isolated by valves, which may not have been completely closed, and may not have been noticed by the local FNG before the tank was filled and the leak began. No one would usually congregate in this area to notice, so bringing criminal charges is sort of ridiculous. In the end, we wouldn't be talking about jailing an Exxon CEO, more like your childhood buddy who didn't go to college and tries to make a living working wrenches in the oil field. It seems like a costly, but honest, mistake to me. I know from working in the area that there is definitely no top-down directive to violate EPA laws. There are literally daily meetings where human and environmental safety are stressed as the highest priority, especially at a larger company like XTO. They definitely realize that the public wants to castrate them for any reason it possibly can and make the utmost efforts to prevent these kind of environmental (and PR) disasters.
In the 80's, women made up most of CS programs around the country. When I went in 2000 - they made up a handful of the entire class. But, engineering was the same (for all engineering majors). There isn't some evil conspiracy to prevent women from entering tech (some of the best innovators in tech I know are women). They simply, for whatever reason, aren't interested in it.
My stepmother was a programmer in the 80's. She quit and decided to be a homemaker because of rampant sexism in the workplace. Among the things she's told me about that, the one that stands out is that the office would throw incentive parties at strip clubs in order to exclude her from being rewarded for her work. She's a smart lady.. but they would give her the most menial of tasks (mainly testing other programmer's code, and having to very thoroughly document problems or else they would be dismissed as her error).
One would hope that the same things aren't going on today, but from reading
I was shocked and thrilled that in my first industry job our staff programmer is a woman in her late fifties. That gives me hope that maybe it wasn't this bad everywhere. She's brilliant at her work and has a very strong work ethic. I truly didn't expect to see any women in my workplace after my experience in college.
TSA is the main reason I have been refusing to fly to and within the US for years now. Colleagues, friends and acquaintances reporting the same. The security craze is costing the US money.
I've flown through most regions of the USA, some 80k miles maybe through too many airports to mention. Been to foreign airports in London Heathrow, Frankfurt, Bucharest, Hong Kong, Singapore and Dubai. All of them seemed pretty similar to TSA style screening, with some having stricter screening practice pre-board and upon departure. For my connecting flights through Frankfurt and Hong Kong, my luggage was searched again, even though I was simply deplaning and re-boarding the same plane. The main difference I've noticed is that the nude-o-scopes are absent, but people are still around to feel me up and rifle through my luggage in most countries. So what's different, from your perspective, in your home country?
Ah, I actually RTFA : "the annual number of earthquakes record at magnitude 3.0 or higher in the central and eastern United States has increased almost tenfold in the past decade â" from an average of 21 per year between 1967 and 2000 to a maximum of 188 in 2011. " I don't think one needs a statistical test for those data. The trend is pretty clear.
You RTFA, and managed to miss that this is unrelated to fracking? I work in the oil and gas industry, so include me among the biased I guess, but I also understand oil and gas production so I'm here to tell you that it is injecting wastewater into fault lines that is causing earthquakes. Not fracking, not oil production, not gas production, but what we call "disposal wells."
In many areas of the USA, water is a scarce commodity, so there aren't any injection wells even though there is lots of fracking.
In many areas of the USA, there is water injection going on in order to "wash out" remaining oil in old formations. These wells are not hydraulically fractured shale formations (the "controversial" process). This has been going on for nearly 100 years.
A Geophysicist I know who works for a large independent oil & gas producer maintains that it has been known for about 20 years that injection wells can cause earthquakes by lubricating fault lines. Extensive testing was done during fracturing at multiple sites and the study was not able to find any data supporting a link between fracking and earthquakes. The instruments used were geophones, which are ultra-sensitive accelerometer devices normally purposed for analyzing formations by echolocation.
All of the comments I see so far clearly didn't click links.. the links mention geothermal production and water injection, the summary indicates that somehow natural gas is extracted by pumping fluid in the ground. That is only true for oil production. In natural gas production our aim is to deliquify wells so that the water isn't exerting backpressure on the gas production, slowing it down and eventually stopping it altogether. Disposal wells are only sometimes used, to get rid of the nasty, brackish, useless water produced from all kinds of hydrocarbon wells.
1. Use a second physically completely separate Internet for infrastructure only?
It's called a WAN Link, They have been around for quite some time and are a lot cheaper than internet circuits in the same tier class for corporate/industrial.
T1s are cheap (usually under $600/month) and can be deployed anywhere (%90) there is copper phone service. (not as cheap as 'consumer' internet, but you wouldn't be using that anyway for something like this now would you??...) And other connections are usually available in most urban/industrial areas (DS3, Metro-Ethernet over copper/fiber, dark fiber leasing, etc...) and are usually covered with SLAs,
And all the major telcos already have all of the above on a "separate" internet infrastructure and even separate them out by customer so they can't even talk to each other (unless they installed a link between and only when they request it) You can even get WAN links between providers that are P2P (T1 from ATT in one location and a T1 from VZ in another and they will be a direct link as far as your router on each end is concerned.)
This is the proper way to link internal systems that you can not link yourself. And if your really paranoid you can even do VPN encryption over that just in case someone actually takes the time to dig up copper/fiber and splice into after some how knowing which in 1,000 pairs of copper/fiber is actually yours in the middle of a street.
Respectfully, $600/month is way, way too expensive for most industrial applications. I work in energy, and we use a tunnel to our VPN provided by cellular companies to link our hosting services to customer sites. It's closer to the realm of $40/month depending on the bandwidth of the connection. All of these options, and encryption, are plausible ways to sufficiently separate ones self from the public internet. I won't comment too much on my experiences with unsecured connections except to say that it is much worse than the summary says it is. These are the discovered devices only..
"Merlin" is an engine brand of Rolls-Royce, a V12 piston engine from the 30's onwards used in a wide variety of aircraft. I can imagine raised eyebrows in their offices, but would they actually sue? I hope not, that would show these lawsuit-happy Yanks what British class really is.
It's a different market segment, so the trademark can't be enforced in that way in the USA.
