Surface 2 MYSTERY: Haswell's here, so WHY the duff battery life?
Apple has just refreshed its high-end portable line with Intel's Haswell chips, delivering Iris graphics and battery life improvements much like those from the recent MacBook Air update. The 13-inch model manages nine hours of battery life, and the 15-inch unit can last for eight hours on a charge.

Vern Raburn, the founder and former CEO of Eclipse Aviation Corp.,
The history of Eclipse Aviation is the story of the largest financial failure in the history of general aviation, one that experts have predicted will have a lasting impact on the aerospace industry.is at the helm of another New Mexico aviation-pioneering startup. Titan Aerospace, a small company thats building a new solar-powered unmanned aerial vehicle in Moriarty, hopes to get a very high-profile boost from its new chairman and CEO .

When the wind blows The hopes, fears and worries of Europes quest for renewable energy Sep 7th 2013 was brought to my attention by John Sobolewski on September 9, 2013 when he handed me his copy of The Economist.
If at times Germany has too much of a good thing, at others it must suck power from nuclear plants across the border in France. And German ministers still worry about the risk of blackouts when the weather is cold, the sun does not shine and the wind does not blow.
Neighbours such as Poland and the Czech Republic complain that power surges from ermany are playing havoc with their grids. ...
Another oddity is that Germany pays some of the lowest wholesale prices for electricity in Europe, yet suffers from some of the highest retail prices. Consumers are burdened with all manner of network fees, taxes and ever-growing charges to subsidise renewable energy.
Is large-scale solar scam/fraud?

Large-scale solar generation of electricity possible scam/fraud several year investigation
reveals that solar works but produces electricity at an inconvenient time.
Solar battery charging and water pumping times are relatively unimportant so solar works fairly well at these applications.
Mr Swan in below article explains the problem of large-scale solar generation of electricity
As of the end of 2012 Germany had more than 30 GW of "nameplate" PV solar capacity and more than 30 GW of wind generation capacity. For a few hours around noon during windy spring days renewable energy regularly meets up to 40% or more of total German electrical requirements.and hence why large-scale solar generation of electricity may be a scam/fraud.
Unfortunately there is a large dark cloud towering above this silver lining. Despite ever-increasing generation capacity, wind and solar sources have failed to consistently produce power when it is needed or significantly reduce German dependence upon traditional thermal generation assets (coal and natural gas-fired plants and nuclear plants). ...
PV Solar generation also displays a great deal of variability and of course is not available after sunset when electricity demand is still quite high. The seasonal variation of PV generation in Germany is even more disturbing with winter values less than a quarter of summer values.
With renewable generation varying by an order of magnitude across the seasons and sometimes within a few hours at night how has the German electrical sector managed to keep the lights on? By depending upon traditional thermal generating assets which must be kept fully operational as "spinning reserves" that are available at all times to back-up renewable sources.

Harbor Freight recently lowered price on
which means more test on AC output.
