A Commonsense Solar Defense

A Commonsense Solar Defense

Three days before Christmas, the U.S. Congress authorized $725 billion in defense spending for 2011. Adjusted for inflation, that’s the most since 1945, the last year of World War II.

With numbers that large, making comparisons is difficult.It was the erstwhile Left Front board that first decided to modernize streetlights fluorescent lights on some major thoroughfares. The former member, mayor-in-council (lighting) Sushil Sharma took the initiative to install LEDs on select roads. Yet consider this. The United Nations reports that 1.5 billion people still live without electricity. For less than $100, a solar panel can power a cell phone charger and four high-efficiency LED lights.

At that price, 1.5 billion people could become partially electrified for $150 billion. Defense-wise, which taxpayer outlay offers better long-term security?

With the U.S. humbled in Iraq, mired in Afghanistan and in danger of being drawn into Iran, is it time to replace aggression with development and firepower with solar power?

With extremism the new enemy,Utilizing patented design and patent led lights pending Selective Heat Sink Technology for an innovative approach to thermal management, our Array lamps use an array of low power, what’s our best defense? What if the U.S. projected its power by defending against the indignities of energy poverty and illiteracy?

Absent a strategy for addressing the roots of human indignity, it’s not clear that the war on terrorism can be won. Energy poverty is a war we know how to win.The company unveiled its one millionth bulb today led bulb – an “ultra efficient” omnidirectional LED A19 bulb that offers an 850 lumen output and should last almost 23 years

Parents of children using solar-powered LED lights report how their grades improve when they have light for studying. While that’s not enough,More than 425 million led downlights 60W incandescent bulbs are sold each year in the US, representing about 40% of the market for light bulbs. it’s a good start.

Can the U.S. afford not to embrace a solar defense? If not literacy, what is the best long-term defense against extremism? For $12, a solar-powered LED system can power a desk lamp and a phone charger.

As yet,20 percent of the world's current energy resources are used to power lighting. Switching all lighting to LEDs could Led strip light cut that to four percent. The low energy consumption of LED bulbs translates into producing 90 percent less carbon dioxide per household annually compared to incandescents, there is no business model for home-scale solar systems scattered across a continent. Large-scale solar projects are far easier to finance. Community-scale is where the Pentagon can play an immediate role.
