A small wind can go a long way


Robert at HansIsland put me onto this option:Quite Revolution wind turbine

How much energy does it generate?
The QR5 will generate around 10,000 kWh per year in a go
od wind site of 5.8m/s average. This is equivalent to five low-energy houses’ electricity demand, or the electrical needs of a twenty man office (i.e. lights, computers, servers, printers, faxes and phones)Aermotor type

I'm not saying go out and buy one of these. But in a country that is littered with windmills (pictured right --and I'm not in Holland!). With The notion that a multi layered grid can be created by employing top engineering to harness "small winds" makes a lot of sense.

In the context of this orchestrated debate over uranium energy and Climate Change we greenoids need to be up with the new tech options. Their utility will vary region to region but there's an option for all conditions I expect. Winds may vary as do what you can grab through solar panels, but there's one option I'm interested in here in Queensland -- hot rock energy.


Studies at ANU and previously at Geoscience Australia have looked at the prospects for Hot Rock Energy in Australia. These studies have established that a very significant resource exists.

A database of sub-surface temperature measurements for the continent has been built. This database contains around 3,500 temperature measurements made in boreholes at depths between ~100 metres and 4 - 5 kilometres. With the database a picture has been built of the way that temperature at depth across the Australian continent. An example is shown below.
