Putting down some of the cost estimates for a single family seastead big enough and nice enough for my family (so this is not the minimal cost design). I expect to have an early seastead and have plenty of backups and redundancy so that when things break I my family will be fine even if we have a few months to go till the next port.

Seastead Budget Estimates
Item Units Price/unit Total cost
Thrusters 3 $20,000 $60,000
Motor Controllers 3 $1,600 $4,800
Solar Panels 16,000 watts $4/watt $64,000
Batteries 100 kw-hours $145/1-kw-hour $14,500
Inverters 6 $1,200 $7,200
Wind turbine 1 $5,600 $5,600
Backup Generators 1 $5,400 $5,400
300 Gal Diesel Tank 1 $2,000 $2,000
Diesel Fuel 300 $3.50/gal $1,050
Kite 2 $2,000 $4,000
WaterMakers 2 $4,300 $8,600
Year Supply of Food 5 $800 $4,000
Liferaft 1 $5,000 $5,000
Total $183,100

Open Issues

  • Cost of living area and structure are not in here yet.
  • I like the "free fall life boats" but have yet to find any prices for them.

Tradeoffs

The main tradeoff I am making is to have solar power and electric thrusters so that I don't need to buy diesel every month, listen to the noise of a generator, or smell any exhaust. The other thing is that solar panels are very reliable. Batteries can be done so that single failures don't kill you, and they tend to degrade gradually over a couple years. Diesel engines can stop suddenly. I would want 2 or 3 generators if that was my main source of power. The solar/electric route is more costly up front.
