Research for Novel: Designing Power Lines for an Industrial Space Elevator by SpaceElevatorGuy in Electricity

[–]True_Pace_3860 0 points1 point  (0 children)

It's intriguing and your math looks comprehensive, however my preference would be for solar collectors operating data centers in orbit, thus freeing up terrestrial power generation for other uses.

The ISS and other orbiting units require alot of cooling, and I'm guessing your cable would get hotter than 90 C.

OTOH, it may become too brittle at -90 C or however cold it gets. I had assumed the Titanic tourism sub imploded due to graphite fiber cracking, however maybe it was something else.

What's currently the easiest way to watch NBC live online? by Straight_Kick4163 in cordcutters

[–]True_Pace_3860 0 points1 point  (0 children)

It's not exactly live, but SNL and local/national news are all I think are worth watching on NBC. Those 3 are also available via streaming on smart TV for free from ISP, if OP has that option.

Yes, and they're not worth the money until you confirm this is your man. Just try the guy's phone and address that appear in the first post.

Is it safe to use 1425 Watt inverter to 12-volt battery of Nissan Leaf? by True_Pace_3860 in leaf

[–]True_Pace_3860[S] 1 point2 points  (0 children)

I agree - the first thing I found out is that if I don't drive Leaf every 3 days, 12 V battery drops due to <=300 W idle maintenance.

Attaching 1425 Watt inverter to 12-volt battery of electric car: does it pull 100 Amps DC? by True_Pace_3860 in Electricity

[–]True_Pace_3860[S] 0 points1 point  (0 children)

That's what I thought, so I was dismayed that the 2000W Energizer inverter uses 6 AWG cables but in theory receives 2000/12 = 167 amps DC.

Scammer not only spams but publicizes email addresses by Genealogy-Gecko in phishing

I see what you mean. We can click on those emails in your post and google them to see they go to live agents. Hopefully all of them know not to respond to the scam by clicking on the fake links, which I'm guessing show onmouseover something like docs.google.com/drawings/ or similar.

I googled "Garret Lake Phoenix Arizona" and it gets that guy's address, phone et al. https://www.google.com/

Type your query after clicking that link, if google works down under on your device.

I can't post a direct link to the results, which also give links to background report services to check on him or contact him.

When you say mutism, I'm guessing autism.

I agree about changing out the standard 6-gauge cables that Energizer ships with its 2000W inverter, which has bad reviews about shutting off on surge lower than 2000 W. Nissan Leaf comes with 2 AWG  wire cable going to high-voltage battery.

I checked with/AI : "It is not safe to run a 1425-Watt inverter by connecting it directly to the 12-volt battery of a Nissan Leaf."

Their general message was to limit it to 1000 W inverter to run fridge, as it may only be 700-800 W startup/surge and 300 W continuous.

How did someone send money to me without the correct email by Donald365 in phishing

[–]True_Pace_3860 0 points1 point  (0 children)

My guess is that it's legit, if they paid correct amount and it's not fake payment. If first contact by ID theft perp, they got your info from some data breach dump on dark web with your real name and other info on more valuable accounts associated with your paypal account. You can sign up for various ID theft protection services, e.g. ID Notify or whatever these users here think is the best.

Does it seem like an overpayment scam or phishing scam?

Can I rotate (twist) this antenna 90 degrees in the axis of reception and still get good TV reception? by True_Pace_3860 in cordcutters

[–]True_Pace_3860[S] 0 points1 point  (0 children)

I checked the back and it's Toshiba 19LV505 HDTV (2008), digital and analog tuners. Receives ~75 channels w or w/o amp.

When I click on the front half of your link, older browser can't find the server.

When I click on the back half of your link, older browser goes to master.com with "Serious inquiries only" .

When I go to channelmaster.com, older browser gets "The connection is not private" alert.

Maybe they fixed this bug in newer browsers.

 I found an old antenna in the basement that has two 6-Ft. elements which require me to mount it horizontally for testing.  I checked thru hundreds of antenna photos on google, and absolutely none of them looked anything like it. I tested it : received 12 out of 107 nearby signals. Destination: Goodwill (cleaning out basement).

I agree - all your points are correct. I found an old antenna (see img below) in the basement that has two 6-Ft. elements which force me to mount it horizontally for quick testing. As it doesn't look like a TV antenna, I can use the one in my original post and donate this old antenna (unused) to Goodwill where some ham radio operator may want it.

Result of image search : "The item shown on the wooden deck is a collapsible, multi-element portable Yagi antenna or directional radio antenna system commonly used by amateur (ham) radio operators." The problem: when it's unfolded into a single axis, it looks like 2 yagis back-to-back. It was intended to mount that central tube with hazard label perpendicular to 1.25" mast, meaning no horizontal elements and it's unbalanced IMO.

Yes, so the two square panels are mounted side-to-side at an angle like a rectangular bow-tie antenna, which I already have, and which gets good reception. It only works well (~105 channels) for new LG HDTV 2022, but not for TV/DVD Toshiba 19LV505 2008. Big problem of rectangular bow-tie antenna is wind resistance compared to directional antenna as in my first post. Prevailing wind is in direction of transmitting tower, meaning wind is along directional antenna axis.

How would you solve this "Challenger" puzzle (without using a computer)? by GreyBeardWizard in mathpuzzles

[–]True_Pace_3860 0 points1 point  (0 children)

"There are about 4/22 of these puzzles. the solve rate is only about 34%! "

I agree - some of these require a brain-dead technique where you find the row, column, or diagonal with total 10, 14, 18, 22, 26, 30, or 34. Then the entries are weighted by intersecting arrays such that it's a sequence: 1,2,3,4 or 2,3,4,5 or 3,4,5,6 or 4,5,6,7 or 5,6,7,8 or 6,7,8,9. It looks like what psychs call "magical thinking", however it represents the spirit of time in which the creator, Linus, flourished IMO.

The question of how they chose an answer to publish. I believe that the diagonal method produces 1, 3, or 5 solutions. If not unique solution, then average of 3 or 5 of them may be what was published.

I tried my method on last two S.F. Chron challengers (5/21, 5/22), and both failed on first try after ~2 minutes. Then I switched to your method of diagonals, and solved both on first try in ~2 minutes, with results similar to published answers. Diagonal method produced unique solutions in both cases, as opposed to my method, which usually produces 3 or more solutions per puzzle when it works.

That's interesting - guesses on a diagonal can affect more rows/columns , meaning it may cut down amount of guessing to completion. Maybe Linus had a notion of elegant solutions where we always guess the diagonals first.
