However, the financial incentive to find those bugs would be huge, and Intel hasn't been kicking rear end on security recently (which is admittedly very hard). Intel isn't kicking rear end because they got lazy. No seriously, they knew about the flaws, but the goal was to outdo AMD on IOPS to maintain edge in the market, so they willingly overlooked blatant flaws to gain that advantage.

How much energy can you reasonably recover from an exhaust gas energy recovery unit as say a percentage of what a HFO fueled reciprocating generator puts out? It turns out our islanded powerstation has an EGER on each of the stacks of our six 3.4 WM HFO fueled MAKs. The recovered heat is currently used to heat the HFO tanks and heat tracing the HFO lines but seems to only use a fraction of the heat (we can keep the fuel heated with only two underloaded MAKs online during plant shutdowns and normally run four when at full production). I am thinking it maybe worthwhile to install a boiler and turbine generator on the heat recovery to save some HFO costs (currently around USD13.5M/yr) and reduce emissions. We are going to hit up consultants but what do Goonsultants think?

Combined cycle retrofits certainly exist, but the cost of engineering (and supporting) a custom solution for what is probably an old plant is probably prohibitive compared to buying an off-the-shelf combined cycle combustion turbine system from one of the usual suspects.

Bluewaters coal-fired power station written off as worthless as renewables risequote:The owners of Australia's newest coal-fired power station have written down the value of the asset to zero, wiping out a $1.2 billion investment in the face of an onslaught of renewable energy.

Bluewaters is an interesting one because it was built because the WA government corporatized the WA power which one effect was eliminating the old policy of buying off the two coal mines in Colley evenly despite the prices. At corporatisation. Muja power station set up a tender for long term supply and both coal mines bid on a long term contracts. Bluewaters wouldn't drop their price so didn't even get a cut of the action. So instead of shutting down the coal mine, they built a powerstation with the hope of selling power to commercial customers. Unfortunately; Bluewaters, despite being a new coal plant, couldn't sell power as cheap as old Muja (with non-ESP flue gas treatment from the 60's because not everything was corportised - Muja got to keep government exemption from the governments own environmental legislation for a lot of things - source, my sister was an enviro there for a few years) so Bluewaters was generally underbid there as well. Bit of an irony that one of the youngest (2009) coal plants in Aus is a chance to be retired before one of the oldest (1966).

Still talking about batteries that have runtimes of 1-3 hours depending on load. That's not enough, and Australia is doing basically what Germany was doing, backing their Renewables with Fossil Fuel generation and doubling down in fossil mining/drilling.

MightyBigMinus posted:what ever happened to your ~half-megawatt (?) battery quotes Somewhat overtaken by events in trying to sort out the electrical safety, SCADA/PLC/Instro issues due to incomplete construction and covid making hard work of all of it. In slowly going through everything, the Exhaust Gas Energy Recovery (EGER) has gone from barely recovering enough heat to keep the HFO tanks heated to where only the heat of one or two generators is more than enough. Additionally, as we get used to the VFDs we have on the two mills in the plant (historically I have only ever worked with mills that had Liquid Resistance Starters or Slip Energy Recovery), I am finding just how awesome it is to be able to slow down your the speed to 40% of full speed on a whim. It has given me the thought that rather than dropping breakers off - with significant process interruption, we can shed 40 - 50% of total site electrical load off the mills via slowing them down with the VFD - it might be good enough to eliminate the benefit of a battery but not sure if the SCADA/mill VFD can react quick enough to be effective load shedding. Once the consulting propeller head electrical engineer can get onsite (was originally going to be onsite in March), I am keen that we look at the battery with pricing, look at sorting out load shedding (either being cute with VFDs or just breaker tripping), assess whether generating some electricity from the EGER is worth it as well as obviously continue sorting out the normal stuff like automation/SCADA and PLC completion /safety robustness / etc.

Well, I found the rather simple manual for our Heatmaster economisers. They are each rated for 600 kw (but assume the amount recoverable is much less than that from the HFO engine running @ 2 MW) and deliver a maximum oil temperature of 180 degrees. Not sure if that will be high enough temperature to be worth trying to run a steam generator/turbine. Going to try to contact the OEM of the Heatmaster (out of Holland, apparently) if they can point me in the right direction of converting hot oil into electricity.

It depends, I disagree with the articles description of the positions as lucrative unless you consider something like $100k/y rich. That's just a typical upper-middle class income especially if you are living in urban areas. The fallout from the Fossil Fuel Industry will be tough. It sucks to have worked on something all your life expect now all the sudden it's no longer necessary.

When I was in school for engineering (15ish years ago) it was common knowledge that you went into the petroleum industry to get paid, it was always listed as the best paying engineering discipline. We also all knew by then it was soulless destructive work hence the good compensation.

I'm not in O&G but am confident that most petroleum/geotech/O&G professionals are not from rich backgrounds. For some, their olds would have been in the industry (and therefore doing quite well) but bankers are the large money rollers and you doubt you see them at isolated work school. Rich bankers daughters/sons don't do 12 hour minimum length hard yakka shifts for weeks at a go in some isolated part of the world. They go to MIT, get parachuted into the top of the organisation and have strong opinions on how others should work. Isolated O&G work is something that pays well relative to your education and the high school you went to. You can clean? $100k/yr for you. You can manage something or are a competent engineer? You will be on $250k/yr. Another bonus about that field is unlike Medicine, it does not have a whole Union of gatekeepers actively doing their best to keep out people interested in the discipline.

Most of the folks are out of Dallas or Houston. A quick search shows the average rent is about $1,400. Average In-State Tuition for four-year STEM Degree will be around 60k in debt. $100k after taxes and 401k is going to leave you about $75k. If you an actual McMansion in Houston, Dallas or suburb is about $500k and that probably won't get you a gated community. They can't afford this. At all.

Oh, so we're getting a McMasion outside the 610. I missed that as an earlier criteria. Looking at the schools listed, we have University of Austin Texas, University of Houston and Rice University. One of them is a graduate student. Houston is the cheapest at 4911.00 but the others are not especially for the graduate. These people aren't going to rich. If they're lucky they'll live off of their investments during retirement. For what it's worth, I always enjoyed Spring, TX. The Woodlands was nice but everyone was kind of a dick, pricey and way too easy to get lost. Gucci Loafers fucked around with this message at 18:09 on Jan 5, 2021 |

France is going to have to get their natural gas from somewhere, and wherever it is it’s going to cause more harm to the environment and geopolitics. France may get its natural gas from Iran, which has dangerous nuclear ambitions and has threatened to blow up Israel several times. Or they could turn to Russia who has dangerous ambitions and invaded Crimea just a couple years ago. Or they could look to the Middle East, a region not exactly well known for its respect of Western legal traditions.
