Small Barrel Wind Turbine for residential rooftop use

In Feb 2007, the Western Australian Sustainable Energy Development Office awarded Graeme Attey a $34,000 grant to develop a modular axis wind turbine system suitable for individual houses and other buildings in urban areas. It will involve the development to commercial stage if testing of an existing prototype proves successful.

Another grant to Dr Jonathan Whale of Murdoch University will examine best practice for placement of rooftop wind systems and establishing of best practice guidelines.

The unit is modular and stands about 1.5m high. Six connected to the grid would apparently power a household. At AU$700 each, it could be a lot cheaper than solar panels in a suitable location, clearly suiting Perth because of its daily sea breeze, the "Fremantle Doctor". The design takes advantage of roof profile to concentrate airflow .

Wind e® - a rotary device can pull out hot air in warm months and moist air in cold months. Located on roof tops and using only wind and pressure differences as their power source they offer energy savings and comfort with low up-front cost.

Wind e® is incorporated with bearing free German Technology vis-a-via a sealed self lubricating steel device in polymer mounted within the steel shaft, for minimal friction resulting in high RPM and consequent more extraction of hot air. This also results in maintenance free and Silent, Smooth and Sustained operation for more than ten years.

So round the year, Wind e® roof turbines can help cut your energy costs; and that means less greenhouse gas emissions and more savings into your pocket!

Roof Turbo Ventilators resolve most of the ventilation problems by moving air constantly, causing trapped air to be replaced with cleaner, cooler air from outside.

The unit discharges the extracted air vertically through the roof cladding, dispersing it to the atmosphere thereby minimising the possibility of re-entering into the building

Associated benefits are:

- The turbine is maintenance free
- Works all the time
- Silent operation
- Performs better than static ventilators
- Does not impact on the environment
- Lightweight construction means roofs do not need reinforcing

Doctors and Pharmacists would know a whole lot more regarding the dangers of vaccines if they
bothered to study the inserts, few if any do. Despite the fact that keep
this in mind, many states are thinking about forcing doctors and other health care workers to use the vaccines, since they do not, anyone
with half a brain should comprehend that the doctors and health care workers do
know something, they just are not telling us. If I remember correctly it
is only about 40% of doctors and nurses that accept vaccines.
I concur with you as to the number of vaccines young
children get. I remember we use to have about three as young children and
my young children received about six to eight. The pharmaceutical companies
just keep multiplying the number, keeps their bank accounts total.
I would bet they, and their youngsters tend not to get those vaccines.
