Fukushima's Collateral Effects

This is part of IEEE Spectrum's ongoing coverage of Japan's earthquake and nuclear emergency. For more details on how Fukushima Dai-1's nuclear reactors work and what has gone wrong so far, see our explainer and our timeline.

What a difference six months make. Last fall, at a smart grid technical meeting organized by IEEE's Communications Society, a Japanese speaker said that his country had no particular interest in making its electric power system more reliable, as it already was very close to 100 percent reliable.

Now we are hearing that because of the Fukushima catastrophe and the temporary shut-down of other nuclear power plants, there are almost sure to be summer shortages that will require the government to impose electricity rationing. The Financial Times reports that Tepco's peak load during last year's (unusually hot) summer was 60 gigawatts; the amount of generating capacity expected to be available this coming summer will be 52 GW. As reported here, Japan's bifurcated national grid will complicate the job of getting electricity to where it's needed.

In a shattering investigative article that led The New York Times on Wednesday this week, reporters Norimitsu Onishi and Ken Belson describe a "culture of complicity" that drastically weakened nuclear regulation in Japan. A revolving door between industry and government involving "ascent to heaven" and "descent from heaven" meant that regulators relied on industry people to do their technical work, so that in effect the foxes were guarding the henhouse.

That system will obviously have to be drastically reformed if Japan's nuclear industry is to recover public confidence and the country as a whole is to restore its technical reputation. The effects could go even beyond that. The Chernobyl catastrophe was a not insignificant factor in the Soviet Union's loss of legitimacy and the collapse of Russian communism. We won't be seeing a political revolution in Japan, of course, but we may see something close to it: a calling into question of the cozy government-big business system that has dominated the country since World War II.

Here’s How We Could Brighten Clouds to Cool the Earth

"Ship tracks" over the ocean reveal a new strategy to fight climate change

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.

The particles produced by these ship emissions can also create brighter clouds, which in turn can produce a cooling effect via processes that occur naturally in our atmosphere. What if we could achieve this cooling effect without simultaneously releasing the greenhouse gases and toxic pollutants that ships emit? That's the question the Marine Cloud Brightening (MCB) Project intends to answer.
