Dr. James Dinicolantono wrote . . . . . . . . . For more than 40 years, we’ve been told eating too much salt is killing us. Doctors say it’s as bad for our health as smoking or not exercising, and government guidelines limit us to just under a teaspoon a day. We’re told […]
Renewables rent seekers keep telling us how cheap wind and solar are, compared to those ‘evil’ fossil fuels, coal and gas.
But ‘price’ and ‘value’ are not the same animals. What we pay for something, and what it’s worth depends entirely upon what we get. And, in relation to the consumption of electricity, whether or not we get it, at all.
Wind power might be ‘free’, but try purchasing it, at any price, when the wind stops blowing.
Comparing weather dependent wind generation with sources available, around-the-clock, irrespective of the weather, is a game played by intellectual pygmies. There is, of course, no comparison.
So when you’re faced with a pile of numbers said to show how wind stacks up against the big boys, the obvious retort is, ‘when’? When I need it, or when the wind is just right?
Donn Dears picks up that thread quite neatly in this…

Diversity is the antithesis of cohesion
Over the last few decades a trend becomes apparent where western society falls apart in ever more splinter groups each living in their own social media bubble, fed by anything but objective or scientific social ‘science’ studies.
The concept Racism which as its name indicates concerns racial thinking has been Conflated with mostly non-existent gender issues and religion giving any splinter group a way to kill off any reasonable discussion.
Doubtless when modern education which is less about facts but more about opinion/emotion has wreaked its havoc upon the youth the concept will be further conflated with any other social issue en vogue.
Evidently the more one encourages society to split itself up the more it will fall apart as a unity. This lack of cohesion will be the undoing of western society as we know it.
Being hardwired by nature social animals we as a species can only evolve further if that cohesion remains intact. The results of lack of cohesion is amply demonstrated by tribal nations such as in the Middle East and Africa.
Never ending war, genocide, disease, over population, famine, repression are a common denominator.
Some ‘visionaries’ foresee the human race living on other planets. Sure, in principle nothing wrong with it.
However to really have any chance of survival in the long term that planet has to conform to very restricted parameters, as conditions found on earth since after millions of years having evolved as a species on earth our bodies are designed to live within the boundaries as set by the earth’s conditions.
Even a small relatively deviation in temperature is enough to make human life very hard reason why so few people live on the poles and why the human race had it’s origins nearer the equator.
We need a temperature within a narrow band to survive.
Now take for example the planet Mars.
It’s dead. It died long time ago, it’s atmosphere consists of for us unbreathable gases (mostly CO2) at about half earth’s pressure making surface life impossible.
It doesn’t have a revolving iron core so no magnetic field to deflect hard radiation making surface life impossible
The water content of the planet consists mostly of permafrost at <250 kelvin making the availability of liquid water near enough impossible.
The surface consists of oxidized rock and a good layer of micro particle dust making articulated earth like machines of any usable size a nearly impossible task to keep operational.
The same dust will enter into any construction made by us and in the long term cause any machine or living entity being perfused by that dust.
This dust is mostly iron oxide. Surface of Mars As an abrasive compound it really does the trick. It is toxic in the amounts found in Mars surface and atmosphere.
It is certainly a compound which will destroy any larger machine due to it destroying bearings and being and electric conductor short circuiting any electronic device, which cannot with our present or to be foreseen technology be totally sealed off.
Than the daily dose of radiation. Already the even the shortest Earth-Mars round trip would be about 0.66 sievert. This amount is like receiving a whole-body CT scan every five or six days. Conditions on Mars aren’t any better due to lack of dense atmosphere and magnetic field. Radiation on Mars
So only subsoil habitation is possible and than at great depth. In order to construct a habitat suitable to sustain multiple generations we need to excavate about the size of the current habited surface of earth which including the surface needed for agriculture (based on 2018 population) Earth has a land surface of 149 million km².
Which needs to be heated since the planet is at <250 kelvin. It also needs to have daylight lighting, earth like atmosphere and pressure. The energy needed to just begin to excavate a small colony, heat it, pressurize it and give it earth like atmosphere is beyond calculation. And how does one obtain this energy? Solar panels won’t work since the sun is to distant, windmills won’t work due to the low density of the atmosphere.
Only one energy source would be direct matter to energy conversion as in nuclear fission and/or fusion. But it would have to be a really huge reactor, or field of reactors to generate this energy. But how do you build that on Mars? How do you build the infrastructure? For that you need energy you don’t have yet.
In other words, to have a real self sustaining colony on Mars which won’t cause inbreeding within one generation you need to deplete all resources on Earth, send them to Mars, invent robots that will reliably prefabricate the living quarters and other infrastructure. After the decennia it takes to do that send at least 100.000 of humans of diverse populations to Mars and hope they won’t kill each other on the trip and the cosmic radiation doesn’t cause a significant mutation.
In conclusion the ‘visionary’ which proposes making Mars an alternative for Earth suffers from an overly active imagination and sincere lack of factual knowledge/comprehension thereof
Due to the significant drop in nuclear power consumption, Germany has been unable to reduce fossil fuel consumption as much as previously hoped. This shortfall is especially the case with natural gas, which has been a central cause for concern given the political leverage held by massive Russian exports to Germany, and to the European Union more broadly. On this issue, progress has been limited, and seems to be getting worse.
As the table below demonstrates, Russian natural gas exports to Germany are only increasing, and show no signs of abatement, mirroring anecdotal reports and the steady progression of the Nord Stream 2 pipeline.
Total imports, including those from Russia (except a 2011-2012 decrease due to supply diversions resulting from extreme cold weather), have increased while both domestic production and consumption have decreased.
In 2016, Germany sourced over 46 percent of its natural gas imports from Russia, up from 40 percent in 2006. The other two key suppliers, Norway, and the Netherlands, both maintained relatively stable exports over the period examined.
In short, Germany’s Energiewende is big failure. Having spent 100s of billions of euros on ‘alternative energy production’ the only result is that the consumer end price for electricity risen to amongst the highest in Europe ( What German households pay for power ) whilst dependence on fossil fuels has augmented.
Worst still, due to the unpredictability of their alternative energy Germany has been forced to pay other nations to please pretty please take their surplus energy of their hands to prevent their infrastructure glowing red from overproduction whilst at the same time having to pay spot prices to import energy those nights the sun doesn’t shine, those cloudy days it also doesn’t do much, those days the wind doesn’t blow or those days it doesn’t blow at all or to strong.
Inevitable conclusion: their endlösung for energy production doesn’t work in real life.
The research, led by University of California neurologist Claudia Kawas, tracked 1,700 nonagenarians enrolled in the 90+ Study that began in 2003 to explore impacts of daily habits on longevity.
Researchers discovered that subjects who drank about two glasses of beer or wine a day were 18% less likely to experience a premature death, the Independent reports.
Meanwhile, participants who exercised 15 to 45 minutes a day, cut the same risk by 11%.
“I have no explanation for it, but I do firmly believe that modest drinking improves longevity,” Kawas stated over the weekend at the American Association for the Advancement of Science annual conference in Austin, Texas.
Other factors were found to boost longevity, including weight. Participants who were slightly overweight — but not obese — cut their odds of an early death by 3%.
“It’s not bad to be skinny when you’re young but it’s very bad to be skinny when you’re old,” Kawas noted in her address.
Subjects who kept busy with a daily hobby two hours a day were 21% less likely to die early, while those who drank two cups of coffee a day cut that risk by 10%.
Further study is needed to determine how habits impact longevity beyond people’s genetic makeups.
Grid stability is likely to be increasingly challenged as power distribution moves from a centralized to a more decentralized model, new research has found.
According to a paper published this week in the journal Nature Energy by researchers from Germany’s Max Planck Institute for Dynamics and Self-Organization and the UK’s Queen Mary University of London, integrating growing numbers of renewable power installations and microgrids onto the grid can result in larger-than-expected fluctuations in grid frequency.
The researchers collected data from grids of various sizes in Germany, France, the UK, Finland, Mallorca, Japan and the US. Based on this data, they developed mathematical models that “can establish the influence of making the grid smaller or of adding a bit more renewable energy” in order to aid in planning, said Professor Christian Beck of Queen Mary University, one of the paper’s co-authors.
The team found that small grids like Mallorca’s displayed larger frequency deviations than larger grids, such as continental Europe’s. And comparing different regions showed that a larger share of renewable generation resulted in larger frequency deviations.
“The grid operators want the frequency to be 50 Hz, but it fluctuates a little bit around this all the time,” said Beck. “We can now establish the probability that the deviation is more than 2 per cent or so, which is a big deviation, and we found that the probability of that is higher than expected from pure random fluctuation.”
Beck told PEi that the research team’s “first surprise was that energy trading had a significant impact on the grids studied” after Germany’s grid and others displayed particularly large fluctuations every 15 minutes, corresponding to spot market trading.
“The grid frequency had big jumps every 15-30 minutes,” he said, “and it wasn’t clear to us before that trading has such a big effect. Most people were worried about renewables because they are unpredictable and certainly produce fluctuations in frequency. Trading gives a similar order of, or stronger, fluctuation, which hadn’t been clear to us or, I think, to most people.”
Comparatively, the research showed that a larger share of renewable generation in a given region resulted in larger deviations from the standard 50 Hz. For example, the UK, with more renewables than the US, also had larger frequency deviations. To integrate more renewables onto the UK grid, the research team recommends increasing primary control and demand response.
“The UK is somewhat special,” Beck said, “in that it has a much higher component of wind power contributing, and it also has an overall smaller grid than the rest of Europe. Still, frequency fluctuations caused by trading seem to be at least as relevant as fluctuations caused by renewables.”
Asked about the effects on microgrids, he said that “the maths allows us to extrapolate the effects depending on the size of the grid. If we extrapolate our results to smaller grids, then indeed we would be implying that the effects are more pronounced there, and if people wish to have a microgrid then they need to relax a little bit the conditions they demand on constant frequency.”
“I don’t think we are saying anything against microgrids,” he added. “You just have to complement them with suitable control strategies to make sure the frequency is constant enough.”
The idea that by some miraculous yet to be invented ‘smart’ grid this problem can be overcome belongs to the domain of futuristic solutions. Obviously the more failure prone advanced electronics you add to the problem, the solution becomes a problem.
And all this still is based on the current situation without having provisions for the enormous extra load Electric Vehicles will put on that grid.
If ever the general transport currently based on hydrocarbons where to be replaced by electric the current grid and further infrastructure would buckle at the first time the 47 quadrillion Btu in 2012 to 94 quadrillion Btu in 2040 for the transport sector alone would be trying to get that of any electric grid, being it smart or super-intelligent.
