Expanded article on Earth system.
Months ago, I bought several bathroom furniture items from QS Supplies. Ever since, they have bombarded me with unwanted e-mails. They have ignored repeated requests to remove me from their mailing lists. There are plenty of more professional suppliers out there, I strongly urge you to use one of them.

Expanded details about Procyon.
There were 240.0 billion car miles driven in the UK in 2013. That’s 386.2 billion car kilometres. [source]
If electric motoring costs 0.34 kWh per kilometre (from your 4 year old link), then that requires (386.2 × 0.34 =) 131.3 TWh of extra electrical energy.
Total electricity generation was 359 TWh in 2013. [source]
So switching to all electric cars would required the UK to increase electricity generation by 37%, according to the article you linked. If we all drove Teslas, which achieve 0.24 kWh/km, then generation would only need to increase by 26%.
We were play testing my friend Sam’s board game this weekend. It features “annihilator towers” – you build up N levels of tower, and then roll N 6-sided dice to determine the damage dealt. Here’s the wrinkle though: If you roll two or more ones, then the tower explodes and the damage is dealt to the home team. What are the chances of rolling two ones, for a given tower level?

This is the second part of my article on Ad Astra space drives. Part 1 is here. Today, TL9 – TL11.
Ad Astra space travellers are forced to use somewhat more realistic space drives than in “traditional” Traveller. Even with antimatter, high-tech interstellar craft typically take a week to travel to or from the jump point. Without antimatter, travel times stretch into months.
I’ve updated my Traveller ship design spreadsheet to reflect this new reality. This article describes the primitive drive technologies available at TL6 – TL8, together with some examples.
I’ve been working on “Ad Astra”, a space opera campaign for Traveller. I thought I’d publish a bit of the background information… it’ll be useful for potential players, and I relish feedback from my critical friends.

The Long Republic (Langerepublik) is a huge German-speaking state that grew out of the human colony world called “Weg” (The Road). Weggers live as nomads, constantly on the move, either on their home world, or in “Caravan Ships” that ply the Main. Weggers are allied with the mysterious “Spiders” who live somewhere in the coreward Main. This has given them access to technology that baffles Core world scientists – particularly gravity generators and apparently reactionless thrusters. This technical edge allowed them to drive the Xa Imperium back along the Main, almost to Xa-Xa.
