"We'll do our manufacturing in space so the pollution stays in space"

"What powers your space manufacturing?"

For "solar panels", press 1!
For "liquid fuels", press 2!
For "nuclear", press 3!

cnbc.com/amp/2019/07/17…
1: Why not just do it on Earth where all your other raw materials are and you don't need to achieve escape velocity all the time?
2. How do you produce your liquid fuels without polluting your residential-zoned Earth?
3. You think flying nuclear reactors into low-Earth orbit is less risky and expensive than operating them on the ground?

Nissan's plan to cut 12,500 jobs with most of the pain taken overseas is exactly the wrong prescription for a business whose least productive factories are in Japan bloomberg.com/opinion/articl… via @bopinion
@bopinion Useful stat to remember is that while Nissan as a whole produces about 40 cars per employee -- one of the best records in the industry -- in Japan it's a pretty poor 15 per person.
@bopinion Only high-end carmakers like Daimler and BMW can normally get away with that sort of high labor intensity. Without exports to other countries, Nissan's domestic operation is no bigger than its UK business.

This is going to drive me up the wall.

Old bar: 45g, of which 25g is sugar
New "30% less sugar" bar: 25g, o/w 13g is sugar

Change in sugar content per bar: -48%
Change in sugar content per 100g: -3.6 percentage points (55.55% - 52%)

HOW DO YOU GET 30% OUT OF THIS???
Have standards of accuracy fallen so low in this era of demagogic leaders and fake news that Cadbury's feel they can just throw random numbers around?

Lying about the size of your inauguration crowd is bad, but the nutritional content of Dairy Milk bars should be sacrosanct. 😭
Please Twitter explain my rookie maths error to me.

I badly want to be wrong about this so that some scrap of decency and normalcy can be said to remain in the world.

This is something that someone actually wrote on the Wikipedia page about the Jacques Brel song "Amsterdam":

en.wikipedia.org/wiki/Amsterdam…
I write about maritime logistics for a living (sometimes) and I still can't think of a more boring thing you could say about this amazing song
Noteworthy is the fact that, at most latitudes and times of day, the shadow cast by a dog is larger than that cast by a hand, unless the dog is very high above the ground

Hey, I’ve now had my #solar panels for 2 years. So here’s a thread about why #solar panels are awesome. 1
The first thing to know about going #solar is that once you do it you never have to think about it. I sell power to the grid during the day and buy power from the grid at night, but that's all automatic. When I turn on the lights the lights turn on, day or night. 2
The next thing to know about #solar is the excellent economics. I estimated in this essay about greening my life politico.com/magazine/story… that my panels would pay for themselves in eight years. It's now looking like the payback will be...yup, eight years. 3

"Contrary to public perceptions, solar panel uptake is proportionally more common in roofs of those with lower- to middle socio-economic standing." Great work by @solarcitizens @VEPC_VU @p_hannam

1/For those who say - "what about renters and people who live in apartments?" there are a few options available. 1. Sun Tenants which works by splitting the benefit of #solar between landlords and tenants - suntenants.com @SunTenants
2/ Then if you live in Victoria the Vic Government is introducing a #Solar for renters rebate from 1st July this year. #springstreet danandrews.com.au/policies/rente…

Nuclear maintenance would literally be a 100,000 year project with almost no room for error--sorry but I'd rather have a ten year replacement schedule for solar panels, lmao.
Even for so called clean nuclear fusion, the plastics produced by seawater extraction would choke the ocean with plastic is under a decade--and that's assuming clean fusion is possible, and not, y'know, on a 50 year rollout schedule from the present day.
It would take building one solar panel a day for 50 years to compensate for current energy use. It takes 5 years to build a nuclear power plant, this means, on average, 1825 need to be under construction during a year at any given time FOR FIFTY YEARS.

THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon

1/ Quick take on the Trump tariff on imported solar cells is that people are going to lose their jobs. Simple Math: Tariffs increases solar costs. Higher costs means less solar. Less solar means fewer jobs. #Solar
2/ Trump country will lose out the most. Big growth in utility scale solar is in the Southeast, Texas and Southwest. All those Southeast solar markets will be hurt MORE by Trump tariffs because they are the most cost sensitive #Solar
3/ The regions of the country with high electricity prices like California and Massachusetts will be hurt but not as much as Trump country. CA and MA markets will see lower margins for developers but don't expect lots of cancellations. Still TBD. #solar
