Energy can be saved through sharing appliances (for instance by using a beamer to watch film and television). Energy plays an important part in automation.

Energy generation

Centralized

Solar updraft tower [1]

+ Low maintenance cost.

+ Uses greenhouses that can be used for agriculture.

-Takes in a relatively large amount of space.

-Solar has a variable output.

Solar power tower

+Desalinizes water.

+Contains a furnace (that can be used for melting iron for instance).

-Solar has a variable output.

Energy use

  • Beamer

100-300 Watts. Can provide for +- 100 people. Per person: 2 Watt.[2]

  • Small led television

57 Watt. Per person: 14-57 Watt.[3]

  • Xbox

185 Watts [4]

  • Wii

18 Watts[5]

  • Desktop (with peripherals):

60-250 Watts[6]

  • Laptop:

40 Watts[7]

  • Netbook:

16 Watts[8]

  • Tablet (Ipad2)

1-3 Watts [9]

  • Iphone

Less than tablet[10]

  • Amplifier

40 Watts and up [11]

  • DVD player

10 Watts and up


  • Nanolight (100W equivalent, 30,000 hours)

12 Watts [12]

  • Led lamp (50-60W equivalent, 50,000 hours)

6 Watts [13]


  • Washing machine

0,81kwh/wash average 9 year average 500 EUR[14] (If 10 people share one machine: 36 years = 200 EUR per person)

  • Dishwasher

175 Kwh [15]

  • Refrigerator

16 Watt [16]

Monetary cost

Solar updraft tower

5 USD per Watt, so 1 MW tower = 5 million USD [17] (Schlaig 2005)

Collector diameter +- 750 meter = 400,000 m2 = 100 acre

Land price US +- 1,000 - 10,000 USD per acre

Argentina < 8,000 USD per acre [18]

100,000 - 1,000,000 for land

Cost of maintenance 40 years: +- 1,000,000 USD [19]



100 W capacity per settler when the sun is shining. This means using anything other than a tablet / smartphone is advised against. Watching television by yourself or with a handful of people should also not be a habit.

1 one MW solar plant will produce +- 0.25 MW average over a 24 hour day.[20]
