Once people accept the mission of reducing energy use as a priority, fresh thinking and trials are encouraged.
Microsoft has sunk a data centre in the sea off Orkney to investigate whether it can boost energy efficiency.
The data centre, a white cylinder containing computers, could sit on the sea floor for up to five years. An undersea cable brings the data centre power and takes its data to the shore and the wider internet – but if the computers onboard break, they cannot be repaired.
Orkney was chosen because it is a major centre for renewable energy research. The theory is that the cost of cooling the computers will be cut by placing them underwater.
