Spendy mercury-free LED bulb supposedly lasts 50,000 hours

Somewhere, in school or on the job, every engineer learns about tradeoffs -- that there is no free lunch, and that, once a design is at all reasonable, gains in one dimension come at the cost of compromises in others.

The shorthand statement of this is the pithy evergreen in design classes: "Good, fast, and cheap. Pick two!"

There's a new bulb out: a 13-watt LED array bulb with an integral diffuser, so you don't see the annoying space-craft look of little tiny rows of LEDs like the first-generation LED lamps offer. It has no mercury, a boon, and lasts about five times longer than its 13-watt compact-florescent competitors, while being much faster-acting and producing a warmer light.

It costs a boatload, at least now ($90). But I still have my first compact florescent bulbs from 1989: huge, heavy ballasts, barely "compact" at all. I'll buy one of these whenever I need a new bulb and gradually switch over all the hard-to-reach spots.

An interesting video comparison with 100-watt incandescent bulbs and 13-watt compact florescent bulbs is available at the link.

Neighbors help neighbors get power from the sun

Co-ops are hugely underrated for their potential to make good happen in the world. As an example, the renewable energy co-op I'm a member of in the Northeast, aptly named Co-op Power, had its first "member to member" solar hot water installation this weekend. The power of this co-op is in its 300-plus members' enthusiasm, and it was in evidence on this day as our trained team hoisted two panels into place, which were making hot water by evening.

Texas forum on what’s new, April 10

For the interest of those who haven't given up entirely on biofuels, I humbly present the National Algae Association forum in Texas on April 10. This meeting will serve as an update on what's new in this promising branch of the nascent sustainable biofuel movement: biodiesel from cultured algae (outside of biodiesel from waste oil, that is).

This week's Renewable Energy World podcast had an interesting interview with the principal of one algae-fuel company, Solix Biofuels. Like all the companies, they have a whole array of challenges to figure out, from competitor algae to stress regimes that are optimal for producing oil. It's actually tough to grow algae -- who knew?

DOD panel calls out power grid disruption threat

Here's another good reason to fix a shaky and outdated power grid, from the Defense Science Board: keeping the Air Force flying during the next terrorist attack.

The military focuses much of its efforts on avoiding global petroleum disruptions. But it has not thought much about power grid disruptions that could affect its own bases, the Department of Defense (DOD) group says in a report authored by former Defense Secretary James Schlesinger

The board says "physical or cyber sabotage -- or even a simple capacity overload -- could devastate U.S. military and homeland security installations and have a frightening ripple effect across the country, leaving everything from sewage systems to border security controls paralyzed for weeks, perhaps months," ClimateWire reports ($ub. req'd, but free trial available).

Investigators noted: "A long-term major power outage would have significant consequences for both DOD and the nation ... Unfortunately, the current architecture of the grid is vulnerable to even simple attacks."

A Generational Challenge to Repower America (as prepared)
D.A.R. Constitution Hall
Washington, D.C.

Ladies and gentlemen:

There are times in the history of our nation when our very way of life depends upon dispelling illusions and awakening to the challenge of a present danger. In such moments, we are called upon to move quickly and boldly to shake off complacency, throw aside old habits and rise, clear-eyed and alert, to the necessity of big changes. Those who, for whatever reason, refuse to do their part must either be persuaded to join the effort or asked to step aside. This is such a moment. The survival of the United States of America as we know it is at risk. And even more -- if more should be required -- the future of human civilization is at stake.

I don't remember a time in our country when so many things seemed to be going so wrong simultaneously. Our economy is in terrible shape and getting worse, gasoline prices are increasing dramatically, and so are electricity rates. Jobs are being outsourced. Home mortgages are in trouble. Banks, automobile companies and other institutions we depend upon are under growing pressure. Distinguished senior business leaders are telling us that this is just the beginning unless we find the courage to make some major changes quickly.

The climate crisis, in particular, is getting a lot worse -- much more quickly than predicted. Scientists with access to data from Navy submarines traversing underneath the North polar ice cap have warned that there is now a 75 percent chance that within five years the entire ice cap will completely disappear during the summer months. This will further increase the melting pressure on Greenland. According to experts, the Jakobshavn glacier, one of Greenland's largest, is moving at a faster rate than ever before, losing 20 million tons of ice every day, equivalent to the amount of water used every year by the residents of New York City.
