    Up to around the 15th century most of the tin production was done by panning if I remember my Industrial Archaeology of the [various Devon/Cornwall locations] correctly. Extraction would move up stream with occassional diversions into shallow mining if the...

    "Inside the radium sanctuary itself, the residual activity was so high from the "contamination" everywhere and from the residues of innumerable sources of the past that it was difficult to charge up the gold-leaf electroscope (mounted on the wall) for...
  • Commented on What else can you do with a Big Dumb Booster?
    pop conception of a space elevator but hasn't -- was to begin with a minimal ribbon and build it up with crawlers that add more plies, as we do with suspension-bridge cables. That permits a modest initial lift to GEO...
  • Commented on Facts of Life and Death
    Re: '...people in bed sits' - Is this the same as No, think single room for everything. It's a contraction of "bedroom/sitting room", bed in one corner, chair and a table in another, maybe very basic cooking facilities and probably...

    Pegasus? Hmmm... List price is the almost the same as for a Falcon 9 for 5% of the payload (and you get to use the Falcon first stage again, 2% for expendable), and there have been five flights in the...

    The Aft Cargo Carrier was one of the solutions proposed for ET conversion. Basically a lump bolted on to the back end of the tank to carry large diameter payloads, but which could be fitted out as a workshop with...
  • Commented on What else can you do with a Big Dumb Booster?
    I've not heard much about Paul Allen's Stratolauncher recently Carrier aircraft nearly done alledgedly, but still nothing to carry. The one advantage of airdrop like this or the Pegasus is flexibility. The small amount of horizontal velocity isn't a great...

    Or 18 if we count SA-500F, SA-500D and S-IC-T as well as the Moon shots, Skylab launcher and 2 unused for the planned Apollo 19 and 20 missions. Keeping up the pedantry... Skylab used most of the launcher intended for...

    All the ball bearings will move in roughly the same orbit. Initially yes, but you'll need some kind of bursting charge as mentioned elsewhere which will start the orbits diverging. For maximum fun you launch prograde and take a trip...
  • Commented on What else can you do with a Big Dumb Booster?
    The lander is designed to land and take off again ... so who says 'resupply' How about saying "Refuel"? The lander is designed to lift off again after it has taken on over a thousand tonnes of propellant, when it...

    you'd have some of the same safety concerns as Shuttle about putting big, dangerous rockets in the payload bay The tanker variant is already (probably, easier to pump from dedicated tanks than scavenge from the mains) going to be launching...
  • Commented on What else can you do with a Big Dumb Booster?
    If you want it straight to GEO though, it may need a fuel tanker because the space ship part has to come back to Earth. You don't send the ITS freighter out of LEO, you deploy the re-usable tug and...

    It's not like he's a Bond villain or something. Of course he isn't. And it's not like the outline of the ITS is familiar in any way......

  • Commented on The iron law of development
    From memory, up until the 1400s most of the tin extracted from the general area of Dartmoor, Bodmin Moor and on down into Cornwall was collected from river bed sand and gravel by panning. The rivers would be worked repeatedly...

    So do you think we'll see 172 new Stewards of Chiltern Hundred Only 86. Although applying for appointment as Crown Steward and Bailiff of the Chiltern Hundreds is the one usually quoted, they alternate with the Crown Steward and Bailiff...

    She's not a Westminster MP, though - and so couldn't be elected as Prime Minister by the House of Commons. Couple of tiny errors in your statement. There's no requirement for the Prime Minister to be an MP, although it's...
  • Commented on The unavoidable discussion
    What the UK really needed was a referendum on building a fifty metre wall around the City of London Or around the central reservation of the M25. Londoners seem to be big on the "Why should we let Brussels dictate...
  • Commented on But it's not April 1st yet!
    Greg, my last couple of builds have started from a bundle on https://www.scan.co.uk/todayonly and added in whatever else is needed. eg todays (Friday) item 6 has Case + PSU, HDD, CPU + Motherboard, the MoBo appears to have onboard graphics...

    I think the only other ongoing mission outside Mars is Cassini in the Saturn system Dawn in orbit around Ceres and Juno due to arrive at Jupiter in July. The theory behind relaying is you'd fly one or two "conventional"...

    There's a selection of antidrone drones in Walter Jon Williams "Deep State". As I remember Wedges are the favourite, a fast fly-by is enough to destabilise most other types although a glancing impact in the rotor area is ideal....

    Cost of a Falcon 9 launch stack (disposable): $65M. Cost of a Falcon 9 first stage (reusable): $45M. SpaceX currently advertise a complete Falcon 9 *launch* for $61.2 million and a Heavy for $90 million. The first stage has been...

    There's also records that indicate that Antarctica was once warm enough to grow trees...which means no permafrost. And it appears to have been in the same position at that time. Very different geographical situation when the trees were there...

    Ultimogeniture's a weird one. The only place I really remember seeing it was in an ethnographic account from I think Kiribati I've heard of it being used in parts of Wales, the idea being similar. The oldest son didn't want...
