Report Urges U.S. to Pursue Space-Based Solar Power
Space-based solar power, according to the report, has the potential to help the United States stave off climate change and avoid future conflicts over oil by harnessing the Sun's power to provide an essentially inexhaustible supply of clean energy.
The report, "Space-Based Solar Power as an Opportunity for Strategic Security," was undertaken by the Pentagon's National Security Space Office this spring as a collaborative effort that relied heavily on Internet discussions by more than 170 scientific, legal, and business experts around the world. The Space Frontier Foundation, an activist organization normally critical of government-led space programs, hosted the website used to collect input for the report.

Solar photovoltaic panels could lead to cheques from your electricity supplier
Paul Norris has the kind of power bill we all dream of - his electricity supplier sends him a cheque.
He generates so much electricity from the solar photovoltaic (PV) panels on the roof of his three-bedroom house in Tunbridge Wells, Kent, that he not only satisfies his own needs but also exports excess supplies to the National Grid. "The main reason I had it installed was because I was worried about climate change, but it's great to actually make some money out of it," he says. "Most people imagine it only really works during a sunny summer's day, but it even produces a decent amount of power on a cloudy day in the middle of winter." |

Power station harnesses Sun's rays
Well, the memory of it kept me chuckling as I toured the extraordinary scene of the new solar thermal power plant outside Seville in southern Spain.
From a distance, as we rounded a bend and first caught sight of it, I couldn't believe the strange structure ahead of me was actually real.
A concrete tower - 40 storeys high - stood bathed in intense white light, a totally bizarre image in the depths of the Andalusian countryside.
The tower looked like it was being hosed with giant sprays of water or was somehow being squirted with jets of pale gas. I had trouble working it out.
In fact, as we found out when we got closer, the rays of sunlight reflected by a field of 600 huge mirrors are so intense they illuminate the water vapour and dust hanging in the air.
The effect is to give the whole place a glow - even an aura - and if you're concerned about climate change that may well be deserved.

TIP OF THE MONTH: Bottled Water
ENDING BOTTLED WATER ADDICTION WILL SAVE MONEY & ENVIRONMENT
BOTTLED WATER ISN'T NECESSARILY CLEANER: According to the San Francisco Chronicle and lawsuits from the Environmental Law Foundation, 40% of bottled water is really just repackaged tap water. Maybe that's a good thing, considering federal standards for tap water are actually higher than those for bottled water.
BOTTLED WATER AND OIL: Supplying Americans with plastic water bottles for one year consumes more than 47 million gallons of oil, according to the Container Recycling Institute. That's enough to take 100,000 cars off the road and 1 billion pounds of carbon dioxide out of the atmosphere. Add in the additional amount of oil it takes to ship the bottles thousands of miles from extraction source to recipient, and your drink of H2O could be categorized with the "Hummers" of the world.
BOTTLED WATER AND BIODEGRADABILITY: Buddha's bones turned to dust a long time ago. But if he had been a bottled water drinker, that plastic would still be laying around. It takes two minutes to drink a bottle of water, but it takes thousands of years for that piece of plastic garbage to go away.
SOLUTION: Buy a water filter and a non-plastic water container (I use stainless steel bottles) of your preferred size. Fill it up in the morning before you go to work or school. Do a quick online search, and you can also find affordable portable water filters for when you are traveling. You'll save yourself and the environment a lot of expense.
