Any idea where I can go to watch these? Looks very interesting!
Everything is on youtube, somewhere

Wow...I've always liked the Vsauce videos, and this one is excellent if you want a little perspective on Earth's relative motion to everything else, what causes it and what it means for us as far as timekeeping. It makes some difficult to envision concepts pretty clear.

After my ten degree ride to Danville to meet old coots this AM my thunb nails were last thing to feel good again. Should have used my heated gloves but under 30 miles thought of how many times going to Lexington in the 80s/90s with no heated gear for all most 50 miles each way. Now remember I am 71 now and on BP meds last three years :bonk: :bonk: . Did get bragging rights as the other 11 did not ride in. Did not make the thumb nails hurt less :tongue: Coming back sun out and raised a few degrees. Just that little was much,mo,better! :cheers: :putput: Have seen no other bikes out the last three days.
Stop at the dealer on ride yesterday and did a double take at a new 900Z kaw! Retro that has the colors that look so much like the first year 1973 KZ 900. It was the only year with a black motor. 1977 KZ 1000 replaced the 900.

You magnificent old bastard. [emoji2]

Coldest ride I ever took I think was just around town trying to find a store open one Thanksgiving when it was about 19 out. That was with the big VN1500C and it did NOT like those temps. Kept wanting the choke to idle right after moving for a while. Then it would get a little heat soak going while waiting for the light to change, and I could run it lean again. Think I probably still didn't have the jetting quite right for the pipes at that point.

Put over 82,000 on my 1500 Kaw twin in less than four years.It had same factory battery when sold with no jumps,charges or tender ever.All ways started even in single temps with the Fi but was rode every day but maybe five in that time. Slowest big bike I ever owned.At 103mph and pulling good it just would come to a stop on pulling? My friends 1500 vulcan with carb would run away from it on big end and had less less hp.Nomad would take it in 1/4. It all so drink gas big time next to the heavy Nomad 1500? :putput:

the FI models probably had a speed governor and made it lay down at that speed. Yeah mine was slow too, but the power just kept coming across the whole range. I had it well above 115 a couple of times, seemingly with more to go. Had more handle left anyway.

12 degrees last night...a little warmer tomorrow...and then back down to well, it could hit zero here at the house....the Colonial Pipeline kerosene pipe should hook right to my furnace!

Any rocket geeks here? No? Didn't think so. But since it's my thread I can hijack it and go rogue.

See the big pipe on the left with the nozzle belching sooty smoke? That makes this an example of an open-cycle rocket engine. That kero (or whatever you're using for fuel) and liquid o2 has to get to the engine in major volume, so rocket engines use pre-burner driven turbines to spin the pumps for fuel and LOX.

The black soot here says this is what they call a fuel-rich pre-burner, which is to say it wastes a lotta fuel, unfortunately. Up to 20% of the engine's potential thrust is lost here. When you see a rocket launch, many times you'll see flames sporadically appearing and licking the outside of the thrust nozzles, and it makes you wonder if there's something going wrong. It's not. As the airflow around the vehicle bends the pre-burner exhaust back into the thrust nozzle flame, there's moments of back-burn where it ignites and tries to self-sustain...but it can't really. Too rich, too much turbulent air. It can't burn back into the pipe because the o2 has been used in the pre-burner so until it exits the system, it has no source.

The Russians blew everybody's socks off in the 60's by creating closed-cycle rocket engines, which were considered impossible at the time. They route the by-products of the pre-burner back into use in the thrust section, which sounds like a no-brainer, but materials and engineering-wise is actually pretty difficult. Wrong temp, wrong pressure, wrong ratio, etc. Plus you generally need two pumps with complex cross-feeds, more complexity and headaches. But doing so gives you a nice boost in power and efficiency.

The Russians were building the best designed rocket engines in the world in the 60's and 70's...I said best DESIGNED because while they were elegant and brilliant engineering solutions, they also tended to explode or fail semi-regularly, due to materials flaws and inconsistencies, and poor build quality. Unlike our facilities where everything had to spec and fit perfectly or be rejected, and materials science was top-notch for the times, the Russian factory workers had pretty much free reign to modify parts to fit if made incorrectly, weren't terribly concerned with details like torque specs and such, and the high temp alloys used often weren't very good quality.

So the BEST rocket engine, if you've got millions in equipment or even your butt sitting on top, is the one that's most likely to work right without blowing up or quitting. In that respect, WE built the best rocket engines of the time. [emoji106]

Oh I was gonna mention...the turbopumps on the Space Shuttle's main engines (not the solid boosters) produce around 80,000 hp to deliver the fuel and LOX to the engines. :eek: ...that's serious fuel delivery.

80000hp just to pump fuel? Defying gravity is not easy business!

nope. That's why it currently costs $1000/lb to put something in space. Elon's got a plan, though. :rock:
