Why domes?

Domes are easy to build, cheap and exceedingly strong. Domes are, in fact, so strong that they provide close to 100% protection from earthquakes, tsunami and storms. Concrete domes are almost 100% fireproof. The lifespan of many domes is measured in centuries, not years. Domes require minimal maintenance. Domes look cooler than anything humans have ever built...

Types

There are 3 main types of dome; geodesic, monolithic and sectional.

  • Geodesic

Geodesic domes are domes made from straight members. Tokyo Hackerspace can make some geodesic dome kits for people working in affected areas.

  • Monolithic

One-piece domes, typically concrete.

  • Sectional

Made of curved sections of metal, concrete or foam.

Uses

  • Temporary shelter or base.
  • Long-term housing.
  • Greenhouse.
  • Storage.

Getting Started

We need to build a small geodesic dome model from bamboo, PVC pipe or metal pipe. We should then build a 4-meter diameter dome for the hackerspace garden, and experiment with different coverings. This would become the THS Dome, and would serve many useful purposes at events.
