2020-09-08 Nikola GM Partnership; Hydrogen

From my comments. From what I’ve seen, Nikola is really trying to get rolling with heavy trucks with hydrogen. That’s where Milton doesn’t have to compete with Tesla. The badger pickup with batteries is kind of a hard sell because it will be competing with Tesla, and that’s nearly an impossibility without some biggie like

2020-09-06 Tesla Alien Dreadnought Giga Shanghai

Some time lapse videos of the Gigafactory Shanghai, Tesla EVs coming off the production line like crazy! Just turn off the sound – he’s not saying anything new and he’s hard to understand. Watch those robot arms go like crazy! https://youtu.be/MfzxxYxJdDc

2020-09-05 Capacitive Dropper Failures In 240 VAC countries

From a comment I left in Big Clive’s youtube video https://youtu.be/jgaCYRc1-og In the past I’ve seen Clive having to replace “used up” capacitors in the ‘capacitive dropper’ circuits of low cost line operated devices. The problem seems to be common in other countries but here in the US I haven’t seen any problems with the

2020-09-05 Tesla Sensors&Self Driving; Truth About Nikola

This YouTube video is about self driving but it shows and tells how the sensors do their jobs. LIDAR is too expensive. https://youtu.be/P8aTDusU7dw **************************** This YouTube video is about Nikola and its business model and about costs of hydrogen vs. batteries. Good. https://youtu.be/7ynupYBLlyA

2020-09-05 Ammonia To Hydrogen For Fuel

This 2017 article is on a website dedicated to ammonia as a the mechanism for transporting hydrogen to be used as fuel. There is a large amount of hydrogen made into ammonia for fertilizer, so it’s an established industry. But this uses methane AKA natural gas as the source for the hydrogen, so it is

2020-09-05 Tesla Stock Will Drop 90 Percent

I hope not. But the market got hit hard last week. TSLA went down a lot but still higher than earlier. I’m bullish on Tesla. The company is much more than ‘just a car company.’ https://finance.yahoo.com/amphtml/news/tesla-stock-could-tumble-over-200529902.html

2020-09-04 Power Outages Caused By Misoperations

This graph is for thevwestern US, I think it said 80 million population. The Misoperations is explained in the text. I noticed that most of the problems seem to be with microprocessors. That must mean there are bugs in the systems. Maybe hardware? Or if the hardware is redundant, then probably software? https://www.wecc.org/epubs/StateOfTheInterconnection/Pages/Misoperations0706-4202.aspx

2020-09-03 Trump builds the very ‘deep state’ he railed against; Trump said Vote Twice

This is disappointing. Let’s hope that Congress can get a law passed to address the many issues that this administration has caused with the media, the public and with the 3 branches of government. https://amp.theguardian.com/us-news/2020/sep/03/as-election-nears-trump-builds-the-very-deep-state-he-railed-against New – Today, Trump urged N. Carolina voters to vote twice. That is illegal and the N.C. authority put out

2020-09-03 Distributed Generation And Islanding

There is a lot of concern for safety when DGs (distributed generators) are connected to the power grid. The grid operators must ensure that none of the DGs feed back into the grid when the grid generator is not operating. They go through several scenarios in this article. https://electrical-engineering-portal.com/protection-impacts-intentional-islanding-distributed-generation From what I see the DG
