A short < 5 min. Video about socialism in the past century.
Americans don’t have to be afraid of socialism; they have to fear communism.

2021-08-20 Queen Of The Night Went Crazy Last Night
My beautiful Queen of the Night went crazy again last night. Tue night / Wednesday morning she went crazy with 5 flowers, one you can see shriveled and sagging in this photo — that’s the one in the second photo. About 10 to 12 bloomed in the last few days.
2021-08-19 Congressmen Who Objected To Electoral Votes
This is the list of congressmen who objected to the electoral vote count. Six senators and the rest representatives, all Republican.

2021-08-19 New! Robotic Weed Killers, Insect Treaters
I’ve thought about these robots several times over the years because for millenia farmers did this by hand, without the carcinogenic (cancer causing) herbicides and insecticides. Now they have built a robotic weed killer that zaps weeds with a Laser. And another farm robotic machine is powered by a Tesla battery.
What makes me elated is that technology can solve problems with solutions that remove things harmful to the environment. So in the future untold numbers of workers will not become cancer victims due to herbicides or poisoned by insecticides.

2021-08-18 Climate Change Argument Ignores Problem!
While this p!ssing contest is going on, the changes in climate are doing more and more damage. If either of these arguers are not able to give a solution to the change in climate then they should both be ignored.
The fact is if these arguments keep on distracting others from solving the problem, then the arguers are part of the problem, not the solution.
It is better to stop adding greenhouse gases and reduce the CO2 down to 350 ppm than do nothing but argue. Even if the above doesn’t help, it’s a whole lot better than bickering about trivialities. And if it’s the right thing to do then there will not be the widespread catastrophe. But doing nothing but argue is just wasting precious time! And the costs of doing nothing will be much more severe and there will be more costs of adapting to a catastrophe!
So stop arguing and give the world solution(s) to the change in climate. Otherwise you arguers will be eliminated when push comes to shove. Mother Nature will go on just fine and humanity will perish. I’m glad I’m too old to be around when the fit hits the shan.
Watch this video Busting Climate Myths.
My comment on a renewables video. A solar park in Gujarat India will be the biggest at over 4000 MW or 4 GW!!
He asked, “How many years do you think it will take for the world to switch to renewable resources?”
It must be done as soon as possible if the world governments want to save their people from disastrous climate change. The effects are already being seen in areas where the people live on low lying land next to the oceans. Sea level rise is flooding some areas and it will become worse. Hurricanes and cyclones will do much more storm water flooding and damage.
This video said that the area was hot – 45 to 48 degrees C, and instead of almost uninhabitable, areas like this will grow and become completely uninhabitable.
The worst part is that some of the effects have occurred in a few decades and will be irreversible – it will take hundreds or thousands of years to put the melted ice back on Greenland or Antarctica. SMH..
2021-08-18 Robotic Delivery on Sidewalks
These small delivery vehicles are used in some areas of Silicon Valley. They have a number of advantages as told in the study. The savings on fossil fuels makes good sense. One disadvantage that I see is the customers would not keep enough food on hand and be dependent on the delivery system.

2021-08-17 PHEVs More Sophisticated Than BEVs
From TSLA Shareholders FB group.
I think most here have no clue of what makes a PHEV work. It’s much more sophisticated than a BEV. It has everything a BEV has including a way to integrate the engine’s output with the battery and electric motors’ output. As in the BEV, the motors also act as generators and do regenerative braking, along with charging the battery. Plus the plug-in charger that BEVs have.
Anyone who believes this meme has any truth to it is misinformed. Don’t believe me? Watch this.

2021-08-17 Laser Hydride Film Stores Hydrogen
This company called Plasma Kinetics has developed a thin film that can store hydrogen at the same volume as a 5000 PSI cylinder but lighter, and lighter than batteries. The medium can be very thin film or disks. The hydrogen is released by shining a laser onto the film. Because the hydrogen does not have to be compressed, the process uses less energy and is more efficient. Also the hydrogen is not under high pressure so less of a fire and safety hazard.
A high pressure hydrogen fueling station costs a few million dollars; the hydrogen fueling station using PK’s cartridges costs a few hundred thousand.
It’s still in development but there is room for improvement.
2021-08-17 BEV Fires Take 40x More Water
I got in a disagreement with a guy about how dangerous hydrogen powered vehicles are. He claimed hydrogen vehicles are more dangerous than lithium batteries. I cited the fires that were occurring in Chevy Bolts recently. So here’s an article that “adds more fuel to the fire” on how dangerous BEVs are. Hydrogen burns but it’s much lighter than air so the flames go up and dissipate, whereas the lithium batteries burn in place and as the cells get too hot they burst, blowing hundreds of cells all over, spreading the fire.
It just happens that most BEVs on the roads are Teslas since they’re the biggest sellers. I would still buy a Tesla in a heartbeat, without hesitation.

If this was an ICE vehicle fire it could not be extinguished with water. (One of my favorite movies from when I was young is “Two for the Road”. There is a scene where a car catches fire. Audrey Hepburn’s character throws water on it and then declares “It likes water!” after it flares up.) Instead the fire fighters would have had to have used aqueous film-forming foam (AFFF) which is a known carcinogen. Not only does it put them at risk it is a environmental danger to all those in the area of the fire especially when, as in this case, the fire is in a wetland setting.
Then there is the gasoline which itself is in the following hazmat categories:
Flammable Liquid – Category 2;
Skin Corrosion/Irritation – Category 2;
Germ Cell Mutagenicity – Category 1B;
Carcinogenicity – Category 1B;
Toxic to Reproduction – Category 1A;
Specific Target Organ Toxicity (Single Exposure) – Category 3 (respiratory irritation, narcosis);
Specific Target Organ Toxicity (Repeat Exposure) – Category 1 (liver, kidneys, bladder, blood, bone marrow, nervous system);
Aspiration Hazard – Category 1;
Hazardous to the Aquatic Environment – Acute Hazard – Category 3
Tesla is working on making BEV fires less likely. Their new design of the battery announced on Battery Day will greatly reduce the size of batteries and allow them to be positioned at the center of the vehicle where damage from side impacts will be much less likely. >>
