At Long Last, we have finished all 5 energy modules, all buried in the ground and all full of water. The only signs of their presence is the red white hazard tapes marking out the locations and thin pipes sticking out of the ground.

It has been a long haul, which included the repair of Number 3 (it got lifted by a flood of rain water), some 50 days of work to install all these Energy Modules, they contain a total of 35,000 litres of water, which can store about 10GJ (giga-joules) or about 2700 kWh of free energy from the sun. It is a big investment of time and money but we should see a payback quite quickly over the first few years of operation once the house is built.
