Computing in the Long Emergency

by

Where will computing go in the coming years? I thought I should find out, so I watched a roundtable and other talks and interviews on the subject (warning: it’s pretty dry stuff). I came away underwhelmed. I struggled to figure out what these guys were seeing that I wasn’t. I’m not sure I’ve figured it out. Eventually I came back to the one key issue that’s missing from their roundtable conversation—and that of most conversations among engineers in the computing world—limits, both ecological and material.

After the nuclear disaster, Japan considers a green future

by

Last March, a 9.0 magnitude earthquake and subsequent tsunami left nearly 20,000 dead or missing and destroyed 125,000 buildings in the Tohoku region of Japan. The two disasters also caused three reactors at the Fukushima Daiichi nuclear power plant to melt down, which released dangerous levels of radiation into surrounding areas and led to national power shortages. Tokyo’s iconic neon signs were switched off as rolling blackouts spread across the country. Faced with the greatest reconstruction task since World War II, Japan is asking difficult questions about the future of its energy supply and just what sort of society should emerge from the ruins.

The motion of the ocean – updated

by

With the exception of tidal energy, our focus thus far has been on land-based energy sources. Meanwhile, the ocean absorbs a prodigious fraction of the Sun’s incident energy, creating thermal gradients, currents, and waves whipped up by winds. Let’s put some scales on the energetics of these sources and see if we may turn to them for help. We’ve got our three boxes ready: abundant, potent, and niche (puny). Time to do some sorting!

Renewable energy standards: If it ain’t broke, don’t fix it

by

When your local utility buys more renewable energy to power your lights and computers, what more do you get besides the power?
You get cleaner air, fewer respiratory health problems, and lower health-care costs.
You get local jobs building and maintaining green power plants and a better foothold in the fast-growing, multi-billion dollar global renewable energy industry.
If you use the power to charge the new plug-in electric vehicles now available, you reduce our imports of foreign oil and increase our energy security.
And finally, you reduce the greenhouse gases that are leading to the severe, threatening weather events spurred by global climate change.

Indian villagers’ lives transformed by new energy delivery system

by

It’s late December and an icy fog cloaks the northeastern state of Uttar Pradesh. Here, far from the cities, smoke rises in dense, choking spirals from meagre wood fires and scantily-clad children shiver against the cold. These are largely farming families, and their mud huts fortified by the occasional brick wall are for the most part devoid of light, heat or clean water. But it is here in Uttar Pradesh, one of India’s largest and poorest states, far away from the country’s straining power grid, that US-born entrepreneurs Nikhil Jaisinghani and Brian Shaad have started to pioneer a wholly different energy system, designed to meet some of the most basic needs of the poorest.

Is deception no longer an adaptive human strategy?

by

“A lie is as good as the truth if you can get somebody to believe it.” So goes the cynical maxim. Naturally, it contradicts the accepted public morality embodied in the saying: “Honesty is the best policy.” That saying is attributed to Miguel de Cervantes though it has been repeated by many others. I rather think that the ancient Roman satirist Juvenal had it right when he wrote: “Honesty is praised and starves.”

ODAC Newsletter – Jan 13

Fears of an EU recession gained ground this week with news that the German economy shrank in Q4. In oil markets this dunked oil prices to a New Year low – though they quickly recovered on Thursday in response to renewed concerns of supply disruption. In Nigeria unions threatened to escalate nationwide strikes to the oil production sector at the weekend if the government fails to reverse recent cuts in fuel subsidies.
