At times news items on alternative, renewable energy and eco/green issues catch our attention and we are driven to give our own views in our ecoEnergyDIY news section.
If there is one thing that worries us at ecoenergydiy.com it is the irresponsible adoption of inadequately checked and tested data and 'scientific' reports by the climate change authorities including governments, the United Nations and the Intergovernmental Panel on Climate Change (IPCC).
The truth is too important to get wrong.
Reported in the Sunday Times (January 17, 2010) under the title it turns out that the significant claim in
the IPCC 2007 report that "the world's glaciers were melting so fast that those in the Himalayas could vanish by 2035" was
only there because the IPCC had read a campaigning report by the WWF based on an article published in 1999 by
the 'New Scientist' who reported some assertions made by a little known Indian scientist.

This article in the New York Times discusses how the weather can have significant side effects on the use and efficiency of alternative energy. Subjects include: ice build up on wind turbine blades; snow on PV solar panels; congealing biodiesel fuel.
Mostly these are negative effects but the article does identify some
positive ones including increased efficiency of PV panels (once cleared of snow!).

Much improved efficiency together with other advantages is claimed for a wind turbine with a new design of cowl/shroud. The cowl modifies the airstream and allows the turbine to rotate faster and extract more energy from the wind passing through. The turbines can be spaced more closely together than open vane turbines and being smaller are claimed to be less intrusive in the landscape.
However it is yet to be seen if the claimed advantages will be seen in practice.
So far the company FloDesign has built a small prototype for
wind-tunnel tests and plans to build a 12 ft diameter one for field tests.
