2021-06-23 High Maintenance #3

Kate J.
The guys had code words for some of the PITAs who frequently called the help desk. One lady, H.M.3 – high maintenance #3, kept asking for the cord replaced on her phone’s handset. I must’ve replaced it a half dozen times.

It turned out that the problem wasn’t the cord, the network itself was overloaded so that at times the voice cut out, it was losing bits, sort of like a loose connection. Looking back, she really was correct that there was a problem, but it was much more complicated than she had thought. All along we were looking at the wrong thing.

Once we found the right place to look for the problem – the overloaded network, we could fix it for good. High maintenance #3 was no longer high maintenance. 👍👍

2021-06-22 How Much Land To Power US?

This article gives an excellent idea of the amount of land to power all of the US using solar panels. Note that the 20,000 sq. mi figure is revised to 10,000 sq. mi or a 100 by 100 mile square that would easily fit in the Mojave Desert, assuming rooftop solar was on most homes.

Later the article gives a link to a map that shows how much land it would take to power the whole world using solar alone.

Later the article links to a map that shows how much ocean it would take to power the world with offshore wind turbines. This is a .PDF.

2021-06-21 SOLshare Peer-to-peer Solar Power Sharing System

SOLshare shares solar power among nearby residences. But it’s a mesh network so the microgrid can connect with another microgrid, which can connect with other microgrids. It’s a peer-to-peer trading platform.

“So that the people who cannot afford the solar system can buy energy.”

2021-06-21 Australia Supplying Lithium And Nickel

Said, “Each EV has about 5000 dollars (Au?) In it.”

Well, the battery pack is about a hundred dollars US per kWh or about $7500.00 per vehicle. It’s hard to believe that the raw material costs make up well over half of the cost of an EV battery pack.

Then he said Denholm noted that the cost of the materials makes up most of the battery costs, and the cathode is the most expensive part and the majority of the fixed costs comes from the nickel and lithium.

He was saying some odd sounding word, and after listening to it a bunch of times I finally figured out he was mispronouncing spodumene.

2021-06-20 Jet Contrails And Climate Change

The Scientists say the contrails from jet engines cause the sky to reflect sunlight out into space, thereby changing the climate.

When we replace many of the jets with electric engines, will that stop the contrails and make a difference?

This article gives more information.

Quote:

<< “The temperature increases related to global warming could be made worse in areas where you have a lot of contrails,” said Carleton. “When you’re increasing the temperature, then that means there is more potential for evaporation of water, which can put more water vapor into the atmosphere and increase temperatures further by increasing the greenhouse effect.” >>

2021-06-20 Thermal Power Plants Use 41% Of The Water

There are those who complain about the amount of water used to mine the battery raw materials such as lithium. But the water used to mine a kg of lithium is only used once. They also complain about the water or other materials used to make wind turbines. That water is used only once.

But every kWh of electricity used takes 15 gallons of water. And here is the major difference: it never stops! The thermoelectric (coal, gas, nuclear) power plants continuously use a staggeringly huge amount of water, 41% of the total withdrawals!! Over a hundred billion gallons per day! And it never ends!

Next time someone complains about water use, show them this and tell them that every time they use that coffee machine, it’s like turning on the water faucet and letting water run down the drain!

2021-06-19 End Of Fossil Fuels

Watson Fixer

Q.) How do you figure this? Only 44% of oil is used as fuel. The other 56% is used for thousands of different products. Just because a car doesn’t use fossil fuel, doesn’t mean a major portion of it isn’t produced with oil! Most products in our society require oil to be produced.

A.) If the process that uses the petroleum releases CO2 into the atmosphere then it will have to be replaced with a process that does not release CO2 into the atmosphere. This may use green hydrogen or electricity.

Q.) Most automotive manufacturers haven’t set a time line to be all electric, the only one I have heard of, has set a date of over a decade out. But fossil fuel won’t be needed in less than a decade you say. Plus, the average car is on the road for 12 years. It’s estimated if we quit building fossil fuel cars, it will take 20-26 years to get them all off of the road, not including collectors vehicles.

A.) Light commuter vehicles will use batteries. Heavy transportation will use hydrogen unless battery technology improves.

Existing ICE vehicles will have to use fuels that are not petroleum, such as biofuels or synfuels.

Q.) What about construction equipment, delivery equipment, air travel et cetera?

A.) See the previous answer.

Q.) Where exactly is all the electricity going to come from? Wind and solar are proving to be no where near capable of supplying current demands, let alone future demands.

A.) This is false. Wind in the US midwest is supplying a large part if the power in states like Iowa, Kansas, Oklahoma, Texas. If Texas was a country, it would be the sixth largest wind power producer in the world with a capacity of 30 gigawatts.

Solar is producing a large part of the power in California, Nevada and many other states. California gets more than half of its power at times of the day, mostly from solar. More and more solar and storage are being brought online all over the world.

Both solar and wind costs are going down making them cheaper than conventional thermal power plants.

Q.) Both [solar and wind] are also creating hazardous wastes, no yet able to be disposed of.

A.) Solar and wind are being recycled. 95% of solar panels is recycled. Lithium batteries are recycled.

Q.) The Netherlands claimed many years ago they would be fossil fuel free by 2020, how’d that work out? Less than a decade, not

A.) That is the Netherlands. The rest of the world is rapidly heading towards a fossil fuel free future.

2021-06-18 Trump Tried To Get DoJ To Overturn 2020 Election

The newsmedia came out with this story today, showing documents that show Trump tried to get the Justice Dept. to overturn the election results of the 2020 election. This is an attempted coup d’etat that is unprecedented in the history of the US. This shameful act is something that should have never happened in a democracy. Our country needs to have regulations that explicitly limits the executive power from doing this ever again.

I shudder to think what could have happened if some of Trump’s appointees, notably Attorney General Bill Barr, had not refused to cooperate. Only custom is preventing these joker presidents from doing horribly inappropriate things.

This link shows only the Newshour news item; it does not show the discussion between Woodruff and Brooks and Capehart about this news item. You should also watch what they say.
