Ramez Naam runs the numbers and finds that in ten years, while that nuclear power plant in your backyard will still be unfinished, solar power will have become cheaper than coal power:
Smaller, cheaper, faster: Does Moore’s law apply to solar cells?
Take a plastic bottle cap and make it buzz and glow. Flip it over and here’s the internals:
The bottle cap I have in mind is the plastic one that comes on top of one-gallon water jugs.
The 3 volt motor sells for $4 at Radio Shack. That’s the big expense item. The biggest challenge, in my limited experience, will be concocting a battery holder.
And yes, this toy is similar to the hexbug nano. But I want to expand on that capability, not just make a DIY version of a pre-existing toy but also make it cooler as well.
I’d like to put some kind of translucent design on the top of the cap, and then I’d like to modify the circuit so it could blink and turn on and off when a flashlight beam is shone on a photoresistor.
In the United States today, there are thirty-five boiling water reactors, of the same type as at Fukushima.
Nuclear decommissioning costs around $325 million per plant. So if all the GE plants were to be decommissioned immediately, GE (which would be awarded the decommissioning contracts since it’s its design), would have revenues of 35 x $325 million = $11.4 billion.
Of course, with a little discreet lobbying, I’ll bet that GE could choreograph Congress into ‘forcing’ it to engage in a more cautious decommissioning process, which could cause the cost to rise to $1 billion per plant.
In other words, by shutting down nuclear power tomorrow, GE could have short term revenues of $35 billion.
Alternatively, it could keep trying to build nuclear power plants. Over the past thirty years, it has been able to clear political hurdles in order to have only one new reactor built. Let’s see, cost of new reactor is $6 billion, divided by thirty years . . . is $200 million/year.
And let’s face it, the political hurdles just got a lot higher.
So if I were the CEO of GE, I think I would now suddenly have the ‘courage’ to call not just for a moratorium on building new reactors, but also for the immediate decommissioning of all GE reactors. That would boost profits by approximately 1500%.
But how do you phase out nuclear power without causing a renewed energy crisis that leads to economic collapse? Well, that’s the sweet part. All you have to do is get out of the way, and solar energy will take over the energy market within the next five to ten years.
According to wikipedia:
As of 2010, solar photovoltaics generates electricity in more than 100 countries and, while yet comprising a tiny fraction of the 4.8 TW total global power-generating capacity from all sources, is the fastest growing power-generation technology in the world. Between 2004 and 2009, grid-connected PV capacity increased at an annual average rate of 60 percent, to some 21 GW
In other words, global solar power is .5% of total power, and at a 60 percent annual growth rate, it will reach ten percent in five years and 100 percent in ten years. So even at current trends, solar power was going to make new nuclear plant construction unnecessary within the next decade.
Breakthroughs in solar power technology will soon render solar power as cheap as paint (because it will be paint). How is the nuclear industry going to compete with that? Big as GE is, I don’t see it winning a battle against the Sun.
Now, there are some things that GE could do to speed up the process. It could for example, promote solar power boondoggles. No, wait, that would actually slow solar power development.
How about, GE promotes tax legislation to provide deductions for home solar power installation? And deregulating and streamlining the home installation process? And maybe, ahem, licensing patents on key solar technologies rather than hiding them in the vault in the vain hope of promoting nuclear power instead?
I don’t know. I’m just looking at the numbers. Thirty-five billion dollars for decommissioning US nuclear plants, versus maybe nothing for building another nuclear plant after all the legal fees are paid.
And of course, if one of those reactors goes haywire, will the public demand that GE pay? And if a city is irradiated, will the government be able to let the CEO off the hook like it did with the Banking and Gulf Spill crises? Or will it need a scapegoat this time?
Maybe the CEO of GE won’t back down from nuclear power because of human pride. Well, suppose a group of hedge fund managers were to get together, and use their GE stock leverage to oust the CEO. Then they put in a new CEO, who declares he wants to shut down all reactors. GE stock will plummet, at which time the hedge fund managers buy up all the outstanding shares of GE. Then the government announces $35 billion (or more) in decommissioning contracts to GE, and GE stock bounces back and goes through the roof, and the hedge fund managers are looking pretty sharp at that point.
Well, I’m just a little engineer and don’t know anything about the world of high finance. I really don’t even have much of an idea of how the world is really run or who really runs it. But I do know that, in the aftermath of Fukushima, a little radioactive rain falls upon us all. And for whoever is running the world, it’s also falling upon his lawn. And that’s probably annoying to him. I wouldn’t want to be the person or persons held responsible for causing that annoyance.
The Nuclear Energy Institute reports:
UPDATE AS OF 10:00 A.M. EDT, SUNDAY, MARCH 20:
A two-part operation to spray water into the used fuel pool at Fukushima Daiichi reactor 4 ended just before 7 A.M. EDT. Japan’s defense ministry announced that the Self Defense Force discharged more than 100 tons of water at the pool, and concluded that much of it reached inside the reactor building.

From Salon Magazine: Where are the robots at the Fukushima Daiichi power plant?
Japan employs more robots than any other country . . . So why are human beings manually pouring water over the reactors at the Fukushima Daiichi power plant?
Well, it’s complicated.
The article proposes that robots aren’t being used because of cultural bias. “The case against robots being used for critical duties is buried deeply in Japanese culture . . . . ”
You’ll have to read the whole article to believe it, and by that I mean: to believe it was actually written and actually published. Sometimes Americans have appalling ideas about other people’s cultures, and I will stop there.
No, as soon as the Japanese Self-Defense Force came on the scene, the offer to use robots from iRobot in the United States was quickly accepted. The Japanese government, obviously, is not impeding the use of robots.
If there’s a cultural problem in Japan against using robots in this operation, it resides entirely within the corporate culture of that nuclear plant. And that corporate culture was imported from America along with the design of the Fukushima nuclear plants.
I was briefly in the nuclear power industry about thirty years ago as a civilian employee in the navy nuclear program. Since military personnel often go on to jobs in the civilian nuclear industry, I’ll assume the culture works much the same on the civilian side too. Without going into my own failures and frustrations too much, I’ll say that the nuclear training program emphasized rote memorization of hundreds of pages of reactor plant procedures. There’s basically a procedure for everything, and originality is discouraged.
So what happens if the situation goes off script?
Well, along with the people who just have poor memories (me), all the free spirits and creative types and risk takers left the program a long time ago. What you have left are a bunch of people who are basically acting as meat robots.
Now, part of their delusion is to believe they are ‘effing animals’ (as one such engineer described himself, with the actual word of course), and they do use outrageous obscenity and gross humor a lot and cut loose when they’re off the job — but on the job, they’re basically meat robots, following every line of the reactor plant manual to the letter. They define professionalism as rigid adherence to the script.
Now the situation has gone off script, and they don’t know what to do.
It’s not that they’re anti-robot, and it’s not that they’re anti-creative, either. It’s just that when it comes to their profession, they’ve had all the creativity and initiative programmed out of themselves by the nuclear power industry’s corporate culture.
I hope the military will take charge, and think outside the box. Because the solution to this one sure isn’t in the manual.
So far, my robot designs have been pretty much just conceptual, but now I’m starting to think about how they might actually be built to serve a real world purpose.
Hence, this shot at a general purpose robot:
The red horseshoe bar is for airlifting via helicopter. I’m using only one camera because two-camera bots are for virtual reality, which this thing is not. I went with the four wheel base instead of the six wheel base, because I honestly don’t see much advantage in six wheels, and with the four wheel base I actually have the capability of turning.
The manipulators are horrid, I agree. If you just glance at them, they’re all right for illustrative purposes. But I need something less cartoony, that actually could be built and serve a purpose. Or did I mention that?

Japan Races to Restart Reactors’ Cooling System
At the request of the Japanese military, a Massachusetts company, iRobot, said it put four robots on a plane for Japan on Friday. Colin Angle, the chief executive, said it had sent two small robots that could measure radiation levels close to the reactors and two larger ones that could pull hoses to spray water on the fuel rods.
He said Japanese soldiers could operate the robots from a protected vehicle.
I hope they get there in time.
