I noticed that the German pebble bed reactor has lots of graphite like Chernobyl, which was one of the mistakes to come out of that incident. I'm not sure of the implications for a pebble bed reactor compared to the Chernobyl design, perhaps one of our more knowledgeable members can elaborate?
I agree with you to some extent, but putting your backup systems (diesel generators) in the firing line is a little worrying, but not as much as storing spent fuel where continuous power is required. This is really pushing it. I think spent fuel storage is still the nuclear industry's biggest failing.
No service industry accounts for all possible scenarios. Firstly, all designs are done to meet some specifications. If your specficiation is to withstand an earthquake of 8.0 and Tsunami of 5m, its too bad you got hit by 9 and 6m Tsunami. Secondly, no human being can think of all possible scenarios.
It is not yet clear if the situation could have been controlled better with timely action. I would not blame bad engineering just as yet.
After all the raving on about how pebble bed reactors are so safe and Thorium is so great this really seems to swing the argument away from nuclear doesn't it. It seems like all these "new" technologies just have new risks.
I keep hearing how thorium reactors are the answer to everything.
Check this link out:
Germany built a thorium reactor, then shut it down four years later. It was too expensive to run. The German taxpayers ended up paying about 100 million dollars to shut it down.
A fair enough concern, but if you visit the site you'll see that its coverage of Fukashima (including a real-time discussion forum) is very much focused on the technical facts of the situation.
You can choose to agree or not with the site author's opinion on nuclear energy, which is no secret (in contrast to that of many of the so-called "experts" trotted out by the mainstream media, who are often current or former members of activist organizations like "Friends of the Earth," Greenpeace and "Union of Concerned Scientists").
"Get government out of the nuclear power indemnification business and let the industry settle at a true cost equilibrium."
Yea now there's a good idea! lets have NO government oversight (evil regulation). don't worry, business can regulate itself! the market will take care of EVERYTHING! great idea,.... oh! and the "market" will have a buying opportunity in Japanese real estate just for you VincePG.
the free market economic theory has now been proven false and dangerous on multiple fronts and is merely a useful tool to be implemented for short stretches, not a permanent scenario. freedman style free markets are as much a science as Scientology.
This catastrophe is a perfect storm of stupid ill conceived ideologies such as deregulation (yea i know its Japan and not the US but similar corporate forces are at play), as well as deceitful business interests in the name of profitability.
people die when company's lie.
These conflicting amounts prompted me to look it up, it seems about 10g for one person. I'm assuming quickly as I also found that 1g could cause lung cancer if inhaled. I also found that 1g could cause could kill a few people due to lung cancer. All that said, if you had 100g and let everyone on earth hold it for a time they would probably all be dead or dying. It's important to have the how explained. Regarding your sperm, I'm assuming you mean in one "sitting", I'm afraid you flatter yourself :-) as apparently there are between 2 and 500 million sperm in one shot, you will at best only manage 1/4 to 1/3 of the women of child baring age.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
