2.HISTORY

• Thumb house –the first earthship building• Micheal Reynolds – founder of Earth

Biotechture.• Design later incorporated in Earthship• Earthship biotecture- company specialising

in designing and building Earthship.

3. CONSTRUCTION MATERIALS

• PRIMARY BUILDING BLOCKS USED ARE

– Rammed – earth encased in steel belted tyres

– Aluminium cans or glass/plastic bottles

9

Rammed earth encased in steel belted tyres

•Automobile tyres

•Filled with compacted earth

•Encased in steel belt

Aluminium cans or glass/ plastic bottles

•Very strong

•Easy to build

•Create beautiful colour wall

•Light shines through the walls

12

4.NATURE OF MATERIALS USED

• Indigenous• Thermal mass• Durability• Resilient• Low specific skill requirements

13

5. SYSTEMS

• Water• Electricity• Climate

14

Water

• Water collection process

• The grey water collection and reuse system

• The black water treatment system

15

• Greywater is gently used water from your bathroom sinks, showers, tubs, and washing machines. (filter plants)

• Blackwater is used to describe waste ware containing feces, urine and flushwater from flush toilets (solar enhanced septic tank or incubater)

16

• Water organising module

• Consists of filters and DC-pump

• Create common household water pressure

• Used for all household activities except flushing

toilets

17

Electricity

• Photo Voltaic solar system

• Collect store and use

• Majority of electricity harvested from sun and wind

• Wind turbines- DC energy

• Power Organising Module- used to store energy from batteries and inverted it for AC use

18

Power organizing module (POM)

19

Climate

• Advantage of the properties of thermal mass and passive solar heating and cooling

• Large front windows with integrated shades

• Walls soak up heat during day and radiate heat during night

• Natural ventilation

6.CONSTRUCTION PROCEDURE

VEDIO (WITH PLASTIC BOTTLE, SAME AS THAT FOR

TYRES ALSO)

7.KARUNA: THE EARTHSHIP IN INDIA

• Earthship in India

• Prakasapuram Village, Kodaikanal, Tamilnadu

• 100% self sufficient

• No extra heating or cooling system

• Luxury home
