Points a) and b) are not as prevalent as you'd think - Americans don't all 'live on credit'. You do see a lot of card-based transactions, but they're either debit transactions or credit transactions of convenience. I'm not sure what the UK equivalent is, but funds I spend via my debit card (looks just like a credit card; even has Visa on it) come directly from my bank account linked to that card. It's like a card-based check (cheque to you). Debit card volume in the US exceeds credit card usage.

The other thing you see is people using their credit card to make purchases to get 'points' or other rewards. Personally I don't bother with that, since the CC companies are betting that you'll 1) forget to pay off your balance on time, 2) let the points expire, or 3) earn fewer points than the yearly cost of the card. I only have CC's with no annual fee, and I don't have time to bother with balance-juggling.

For a start the amount of water available is limited, and more needs to be pumped in at some stage.

You're still thinking of old designs. LFTR reactors, like all Molten Salt Reactors, do not require ANY water as a primary or secondary coolant, and can be built anywhere, not just near a river or other large source of water (when the secondary heat exchanger feeds a gas turbine).

For example, a 4x8 foot router table can cut up an entire sheet of plywood to make self-assembled furniture.

Thinking outside the box a little, why not have the router move by itself on the plywood? Your 4x8 'table' would be reduced to either:

1) a wheeled router with decent X/Y awareness and a bit that has a roller ball on the tip to prevent over-penetration and damage to the underlying surface. The plywood can be arranged on any flat surface.
2) a pair of channels that clamp onto sides of and span the plywood in one direction and a crossmember that makes up essentially a giant X/Y plotter with a router at the intersection. The channels and crossmember can be disassembled and stored away easily.

You don't necessary need to dedicate a 4x8 area for a particular task using either method.

I already had most of the components laying around, but I did buy power supplies for the Pi's. I also have one in the attic running dump1090 and the upload client for flightradar24 - it has no case either, and I'm using a <$15 RTL tuner from nooelec.com.

Flash Card: $6
Case: None - taped naked to the back of the TV
Power: About $7
HDMI Cable: $3
Ethernet cable: already had tons laying around, or could make one for $1

Grand total: $17
