2020-03-07 Coal And Its Evil Results

In China, industries burned coal and people burned coal for cooking and heating. In cities like Beijing the air pollution was so bad that it was hard to see the stop lights and pedestrians had to wear facemasks. The pollution killed estimated millions of people with lung problems. China realized this and has done a lot to cut air pollution.

p.90 “as public awareness of the dangers of air pollution mounted, the Chinese government moved quickly. It shuttered old coal plants and create a new regulations for all new plants. In some regions, it cancelled all new coal plants completely.

Thanks to these new policies, some experts estimate that over a hundred and ten thousand fewer Chinese people will die of pollution related deaths in 2017, with an additional 2.1 million rescued from debilitating a lung disease. The world is better off, too in no small part because of China’s moves, global greenhouse gas emissions have stabilized over the past three years.”

But we in the U.S. still use coal to generate 1/3 of the electricity. I’ve been reading “Climate of Hope” and I have been finding out how evil coal and the industry is. These are some excerpts from the book.

from “Climate of Hope” p.85
“PROPER REGULATION.
For over a century, mining and energy companies have been able to privatize coal’s profits while socializing its costs. Translation: corporations make money and taxpayers pay the price. This is still largely true. And yet the many ways in which mining and burning coal imposed costs on the rest of us are rarely recognized. Coal companies pay neither to care for people their plants sicken nor to clean the air of the toxins their plants emit, to say nothing of the huge climate costs imposed by carbon emissions. In a properly functioning market, coal companies would have to account for the costs they impose on society. Instead, those costs are still largely borne by society.”

p.86 “And while the Trump administration may gut [the Clean Power Plan], it’s worth remembering what happened from 2010 to 2015, when emissions fell and so many plants closed: the price of wholesale electricity fell by a quarter, and there was no increase in the frequency of power outages. We can cut costs /and/ emissions without sacrificing reliability — or human lives.”

p.87 “A good example of how Beyond Coal has worked comes from Omaha, Nebraska. The Omaha public Power District (OPPD), a local utility, had owned and operated a large coal plant, its North Omaha Station, for more than 60 years. Since it had been built well before the Clean Air Act, it was not equipped with technology to limit its pollution. The act had stipulations for this, of course, mandating that the plant update pollution controls whenever it modernized the plant. But OPPD never upgraded the plant, allowing it to become one of Nebraska’s largest sources of air pollution. A Nebraska state legislative study linked it to 240 asthma attacks, 22 heart attacks, and 14 deaths a year, imposing $100 million in health and environmental costs on the community.”

“Nebraska’s Sierra Club chapter decided that this plant was a prime candidate for the Beyond Coal campaign. The chapter has spent years talking with the community about the plant’s health hazards. But it was only when the club demonstrated to the utility that moving from coal would be cost-effective that the situation changed. In June 2014, OPPD approved a plan to retire three of five coal-fired units at the plant by the end of 2016. Meanwhile, they promised to convert the two remaining units to cleaner-burning gas by 2023. Even better: the utility committed to implementing energy efficiency measures and investing in substantial new wind power. By 2018, one-third of the area’s power will come from renewable resources.”

p.88 “SUBSIDIZING THE PAST
Despite its health dangers and bad economics, government still subsidizes coal in ways that give it a price advantage over renewable and other cleaner-burning fuels. Consider the Powder River Basin, which straddles Wyoming and Montana. The basin contains two of the world’s largest coal mines, which alone produce a fifth of the nation’s coal. The entire region produces about 43% of America’s coal, or nearly 500 million tons each year, virtually all publicly owned. Yet, amazingly, the US Department of the Interior has not classified Powder River as a coal producing region.

If it did, it would have to sell the coal from public lands in a fair market, with competitive auctions. Instead, current rules allow coal companies to buy publicly-owned coal at whatever price they set. This not only deprives taxpayers of the true financial value of public coal, but it also enables mining companies to flood the energy market with subsidized coal, unfairly competing with gas and renewables. Taxpayers get cheated out of nearly $3 billion a year in the deal. There was a lot of talk in 2016 about a “rigged” economy. Well, the energy market is rigged in favor of coal. And while coal is still losing badly, it is hurting the rest of us on its way down.”

“The Obama administration finally began to limit these giveaways in 2016, by imposing a moratorium on new leases of coal on public lands. But existing leases, at far below market value, remain intact. One study estimates that just removing the federal subsidy would reduce demand for Powder River coal by up to 29%. Ending the sale of coal from public land would raise the price of coal to market levels, forcing it to compete on a more level playing field with cleaner fuels like renewables and gas.

Because of the political power of the coal industry, the federal government props up coal companies in other ways too — ignoring their use of creative accounting to shift liabilities (like worker pensions and environmental cleanups) to shell companies they allow to go bankrupt. By allowing this scam our legislatures and regulators hurt coal workers and impose costs on taxpayers. Time and time again, as mining companies run out of money, courts have let them take the money set aside for pensions and use it for their own operations, leaving the public to pick up the uncovered costs. In 2015, for instance, a bankruptcy court allowed a mining company to use funds set aside for the pensions of 208 Indiana minors, spouses, and widows to pay its lawyers instead. Yet even after they go bankrupt and abandon their employees and neighbors, coal companies managed to keep paying the politicians who have protected them. In 2016 bankrupt coal companies gave federal and state candidates nearly $1 million from their corporate political action committees. So civic-minded!”

p.90 “China and India both still have a long way to go to wean themselves from coal, but both are making progress, and other countries are moving even more rapidly. The UK has announced that it will eliminate is last coal-fired power plant by 2025. In 2016, there were several brief points at which absolutely no electricity was being generated in the UK by a coal — a first since 1882. Portugal is routinely powered by renewables alone for days. And in countries from Myanmar to Chile, citizens are pushing back against coal — and winning. The international energy agency found that renewables like wind and solar represented more than half of the total global growth in electrical generation capacity in 2015 and that this trend would accelerate over the next five years.”

p.91 “Coal is the single greatest threat to civilization and all life on our planet”, the scientist and early climate change pioneer James Hansen has said. America helped lead the world into the industrial revolution. Today it is helping lead the world out of one of its worst legacies. In 2015 the Sierra Club and Bloomberg Philanthropies increased our goal for Beyond Coal. We had originally aimed to cut coal power by 1/3. Now, we are aiming to cut it in half by the end of 2017. The GenOn Potomac plant — the backdrop for our kick-off announcement on that hot July day — is now closed. And a coal free world is finally in our sights.”

More Coronavirus Covid19 information

Why are Costco, Target, etc. running out of toilet paper? Are people using it for facemasks? Are they using it instead of kleenex? Very strange.

Time Magazine has an article about how the US healthcare system is not good for preventing the Coronavirus epidemic.

More than 150 cases of the coronavirus have been confirmed in the U.S. so far. But the structure of the health care system is complicating the response.

2020-03-04 The High Cost of Staying Alive

We went out to Hennessey’s in downtown San Juan Capistrano, and I talked to a guy who is waiting on a list for a kidney. In the meantime he goes to a dialysis center for treatment three times a week for four hours, brings his laptop and watches movies. It costs his insurance $7,400.00 per treatment. He said that in another country it would only cost $300.00. There is something wrong with our medical system where it’s almost impossible to pay for a recurring lifesaving procedure that’s absolutely mandatory. Seriously, your life is just a large amount of expense that some insurance company would like to avoid. Your life, or your money? It’s a very disturbing thought.

2020-03-03 The 5G Technology is NOT Linked to The Corona Virus

This false claim is being spread around the Web by conspiracy theorists, one being David Icke. There has never been any evidence linking the two. Be aware that these articles use pseudoscientific terms that attempt to make the reader believe the claims are based in fact, but they’re not. Don’t be tempted to go over to the Dark Side by these deceptive articles. Be wary.

2020-03-02 Life’s not easy in So. Calif.

From FB comment.

If you don’t vote for change, the whole world’s going to go to hell. We had better change the way we live, and cut back on fossil fuels, and change to renewables, or else there’s not going to be any livable world for the future generations!

If your relatives moved out of state, more power to them. We have plenty of people here who are willing to put up with the high cost of living just to have a decent job. If your relatives were smart they would market themselves into a better paying job. They would take evening classes to upgrade the skills they need to get a better job, and keep looking for an opening. If they stagnate, they’ll fall behind and end up having to abandon their good life here and find a cheaper place to live. That’s life. 🥺🥺

2020-02-29 Volume Control Pot Repair Help

I found that if I clean the volume control and it’s still intermittent, it helps if I connect a resistor from the center pin of the volume control to the ‘cold’ or common or ground end. The resistance was about 10 percent of the value of the pot. Say it’s a 5k pot, the resistor might be 560 ohms or less.

There are two kinds of malfunctions of volume control potentiometers. Both are caused by excessive wear on the resistive element. One malfunction is where the worn spot is causing the resistance from the center wiper pin to the cold or ground end to go higher when intermittent. This sounds like the audio is going from normal to louder. This is where using the resistor from center pin to cold end does the most good.

I connect a resistor from the center pin of the volume control to the ‘cold’ or common or ground end. The resistance was about 10 percent of the value of the pot. Say it’s a 5k pot, the resistor might be 560 ohms or less.

The other malfunction is where the resistance from the center pin to the pin on the hot end of the pot goes from normal to higher when intermittent. This sounds like the audio is going from normal to silent. This is where using a resistor from the center pin to the hot end of the pot does the most good.

I connect a resistor from the center pin of the volume control to the ‘hot’ or maximum volume end. The resistance was about 10 times of the value of the pot. Say it’s a 5k pot, the resistor might be 47k ohms or so.

The values of the resistors can be adjusted to cause the normal volume point on the pot to move to a new, unused good spot. This can reduce or stop the intermittence.

These changes take only a few minutes to do. It’s easy to do, and undo if needed. And it can save a lot of hassles of obtaining a replacement pot and replacing the original intermittent pot.

But probably the best thing about this is it can rescue a bad pot and avoids having to cannibalize some other radio to get a working pot, because it is often impossible to obtain an exact new replacement pot.

2020-02-28 CoViD19 Novel Corona Virus

The problem with CoViD19 isn’t the ARDS (acute respiratory disease syndrome), it’s the inability of the health care system to respond to an overwhelming number of cases. It’s treatable *if* there are enough staff, facilities, equipment and supplies to treat every patient. You had better hope you catch it and get adequate treatment before the system is overwhelmed.

I found that 100 uH was a good all around value for these solar garden light circuits. But at the time I made these around 2009 the 5252 4 legged chip was uncommon and almost all the garden lights used 2 discrete transistors. I don’t know why they started using the 4 legged 5252 – it would have made more sense to use a 4 pin surface mount chip.

I bought a few dozen 100 uH 10% chokes from an online guy and I measured them at 75 to 80 uH with two different meters. I emailed the guy and I sent them back and he refunded the $$. He also measured them at too low a value with more than one meter, so he had no explanation for the out of tolerance issue. This isn’t the first time I’ve had this problem.

So I gave up on RF chokes for this circuit and started buying the Fair-Rite 594300(something) 3/8 inch or 9mm ferrite toroid cores for 12 cents apiece and winding a 8 inch or so piece of wire on them to make any value of choke that I need. They’re lower resistance so have less I squared R losses than an RF choke – every loss takes away from the brightness of the LEDs. I’m much more satisfied by the results. Every electronics tech or hobbyist should have a few dozen ferrite toroid cores in his parts stock to quickly wind a needed value of inductance. The cores can be from .25 inch or 6mm up to more than 1 inch or 25 mm but larger sizes get expensive. You can get them already wound, of course. A good source for small ones were the CFL lights.

2020-02-19 Nobility 15 transistor Radio Repair

2020 Feb 18 – Nobility 15 transistors OTL
S/N (?J)29549
I replaced the electrolytic capacitors. The spkr buzzed when I touched the volume control. Nothing from the detector (transistor). It’s unusual. I pulled and tested some IF parts including one of the transistors, no problems found – transistor tested good. I called it a night.

Next day, I tried to inject a low level 455 kHz modulated signal and got nothing. I wasn’t sure if I was getting output from the signal generator so I connected it to the RF input of a signal tracer, nothing. Instead, I connected the AF input of the signal tracer and I hear the modulated RF. That’s backwards! So I checked the signal tracer, detector diode was okay. I’m puzzled. Back to the radio, I probed around some, not getting anything. I probed the transistor next to the variable capacitor and it seemed to not be working. I unsoldered it and tested it and it tested okay. So I soldered it in and the radio worked! I don’t know what I fixed! ?? Weird! I put the radio back together and it’s working fine.
