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

Solar updraft tower [1]

Cost per Watt of capacity = 4 EUR [2] (Up to 85% at higher latitudes) [3]

Cost per watt of capacity (200 MW): 4 EUR, (50 MW): 6,04 [4]

50 MW (Spain, 1800) cost per Watt: 20 EUR

200 MW (Spain, 1800) cost per Watt: 12 EUR

+ Low maintenance cost.

+ Uses greenhouses that can be used for agriculture.

+ Produces energy at night at a reduced rate [5]

+ Produces energy when overcast [6]

+ May be able to desalize water by using condensation [7]

-Takes in a relatively large amount of space.


Solar power tower

+Desalinizes water.

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

-Solar has a variable output.

PV panels

Cost per Watt = 6 EUR (Africa, 2000) - 13 EUR (Netherlands, 900) [8] [9] [10]

+ Decentralized

- Variable output

Energy use

  • Beamer

100-300 Watts. Can provide for +- 100 people. Per person: 2 Watt.[11]

  • Small led television

57 Watt. Per person: 14-57 Watt.[12]

  • Xbox

185 Watts [13]

  • Wii

18 Watts[14]

  • Desktop (with peripherals):

60-250 Watts[15]

  • Laptop:

40 Watts[16]

  • Netbook:

16 Watts[17]

  • Tablet (Ipad2)

1-3 Watts [18]

  • Iphone

Less than tablet[19]

  • Amplifier

40 Watts and up [20]

  • DVD player

10 Watts and up


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

12 Watts [21]

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

6 Watts [22]


  • Washing machine

0,81kwh/wash 1600 W average 9 year average 500 EUR[23] (If 10 people share one machine: 36 years = 200 EUR per person)

  • Dishwasher

175 Kwh [24]

  • Refrigerator

>12 Watt [25] (374 L, no freezer, 700 EUR)

12 V refrigerator 4,7 Watt 50L (700 USD)[26]

Monetary cost

Solar updraft tower

Collector diameter +- 750 meter = 400,000 m2 = 100 acre (60 soccer pitches)[27]

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

Argentina < 8,000 USD per acre [28]

100,000 - 1,000,000 for land

Cost of maintenance 40 years: +- 1,000,000 USD [29]



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.

A 1 MW solar plant will produce +- 0.25 MW average over a 24 hour day.[30]
