Wrapping Up Another Year . . .
I’ve gotten a lot of nice comments about my recent blog, Stirring The Pot – On Climate Change. And several people asked about a PDF copy, so I posted a copy under the Greg’s Musings tab on the top menu.
And here’s a few more. And this one is from 1934.
And here’s one from the UN, saying we’re all doomed, if we don’t reverse ‘climate change’ by . . . 2000.
And here’s some data from our northern neighbor.
For example, Vancouver had a higher record temperature in 1910 (30.6C) than in 2017 (29.5C).
Toronto had a warmer summer in 1852 (32.2C) than in 2017 (31.7C).
The highest temperature in Moncton in 2017 was four degrees cooler than in 1906.
Brandon, Man., had 49 days where the average daily temperature was above 20C in 1936, compared to only 16 in 2017, with a high temperature of 43.3C that year compared to 34.3C in 2017.
I’ve talked about Elon Musk and his SpaceX company.several times before, most recently about a month ago, with his Starhopper flight.
This first flight only flew to about 500 feet before it landed safely, just as was planned.
This was the first test of his Starship, built to take people of the moon. Now he’s readying the next version, the Mk1
This one will test fly to about 60,000+ feet before returning to earth.
One thing I like about Musk’s Starship is that with every iteration, it looks more and more something that Flash Gordon or Buck Rogers would fly.
I still get goosebumps watching the simultaneous landing of the two Falcon Heavy boosters back at the Cape last April.
The Falcon Heavy used 3 Merlin engines with about 900 kN of thrust each and would be capable of lifting a fully-loaded 737 aircraft.
The Starhopper that flew last month used one of the new Raptor engines, with a thrust of over 2000 kN. And the Mk1 will use 3 Raptors for over 6000 kN, or over 1.3 million pounds of thrust.
WOW.
But the full-blown Starship, capable over carrying 100 passengers and cargo for a settlement to the moon, will use 36! of the Raptor engines, for a thrust of over 15 million pounds.
That’s twice as much as the vaunted Saturn V, which will make it the most powerful rocket in history.
Go Elon!

Auto-correct has become my worst enema.
