Wind Costs More Than It Saves…?

February 11, 2011

“…The 280ft turbine situated in a business park near the M4 in Reading operated at just 15 per cent of its capacity year, meaning it generated £100,000 of energy, despite attracting subsidies of £130,000 from the Government.  Since 2005, when it began producing energy, the turbine has been subsidised with £600,000 of public money but has run at an average of 17 per cent of its capacity.  Figures were published as ministers promised to crack down on the spending of substantial sums on turbines built in areas without enough wind to make a significant saving.  The turbine in Reading is capable of generating two megawatts (two million watts) of electricity at any time, but last year worked at 15.4 per cent of this rate, producing 2,692 megawatt-hours (MWh) – the total amount of energy measured in hours – over the year…” Nick Post in Today’s Telegraph 11Feb11

Yep, wind turbine costs more…

CO2 Concentrations — How about the benefits?

February 11, 2011

“Many books and reports rail against mankind’s usage of fossil fuels such as coal, gas and oil because of the carbon dioxide or CO2 that their combustion releases into the atmosphere…. Now, however, comes a book that does just the opposite by describing a host of real-world benefits that the controversial atmospheric trace gas provides, first to earth’s plants and then to the people and animals that depend upon them for their sustenance…” A.

Sometimes, even VCs get it right

February 6, 2011

“…Cleantech companies just can’t seem to get it right.  At least, that’s the notion Peter Thiel — a co-founder of PayPal and president of Clarium Capital — subscribes to when he looks at cleantech companies as potential investing opportunities. He made the comments at a Commonwealth Club event in San Francisco Wednesday.

“ ‘ …Most of the people who run cleantech companies are sales people, not engineers,” Thiel said. “Something seems to have gone quite wrong with cleantech.’

“…As a result, most cleantech companies that try to develop alternative energy forms are building power sources that are more  expensive. Solar panels, for example, are still not a cost-efficient way to generate power, Thiel said.  ‘We need something cheaper, not more expensive,’ he said. ‘It doesn’t matter if the energy is cleaner, it doesn’t work if it’s more expensive.’ ” — Matthew Lynley, VentureBeat, 3 Feb 2011

The End of Wireless Profitability

February 3, 2011
Just why are managed services and application services vital to sustain the network’s profitability?
/
Should a mobile network persist in selling the ‘lowest-common-denominator’ IP based capacity, the provider will have no recourse but to market a discounted commodity. As broadband applications consume higher capacity, these applications become intolerant of, lost packets, out of order transmissions, delay or congestion.
/
At the same time, the content provider can play the various “me-too” wireless networks against one another to lower the allocated capacity costs that wireless carriers will attempt to pass along to them for supporting their resource-intensive content.
/
We have designed the Power Grid Network to deliver a virtual circuit resilience / privacy / performance value set.  Establishing our best of breed, vendor-independent network of excellence will immediately differentiate us from other vendor-driven network architectures.  The PGN will sell excellence on an as-used basis — the lowest cost solution and the highest market value rolled into one offering set.
