It would seem that it's a bad decision by the Chinese to fund/build this design since the first projects using this design are many years late and many billions of dollars over budget (and still not operating)... but, of course, it doesn't seem to be possible to build a nuclear reactor anywhere near on time or budget. The problems with the EDF reactors cover the gamut from structure (concrete and steel) to mechanical (valves, etc.). Of course, they are developing a new, enhanced, better, EPR design which promises to fix all of these problems... want to bet? As for pebble bed... good luck with that. It's a new unproven design. Only one prototype has been built (Germany) and it closed due to many problems: No possibility to place standard measurement equipment in the pebble-bed core, i.e. pebble bed = black box Contamination of the cooling circuit with metallic fission products (Sr-90, Cs-137) due to the insufficient retention capabilities of fuel pebbles for metallic fission products. Even modern fuel elements do not sufficiently retain strontium and cesium. improper temperatures in the core (more than 200 C above calculated values) necessity of a pressure retaining containment unresolved problems with dust formation by pebble friction (dust acts as a mobile fission product carrier, if fission products escape the fuel particles)
Ah yes, the powerful anti-nuclear lobby which has resources of thousands of dollars has somehow managed to push aside the nuclear industry which has resources of billions of dollars. "If only we didn't have all those pesky regulations and have to worry out nuclear waste for thousands of years and could have more subsidies and free insurance then we would be much cheaper." Nuclear power has gone from too cheap to meter to too expensive to matter and it has nobody to blame but itself.
For some reason, China and France are building this reactor in the UK using a new, French EPR design: https://en.wikipedia.org/wiki/... The Chinese are also building this type of reactor in China so pebble bed may not be working out as well as hoped. Of course, the EPR design has its problems. It has been built twice (France and China) and both of these have safety problems that may prevent them from getting approval to operate.
It's failing on its own merits. Even with subsidies, it's too expensive and can't compete. The UK just approved a new nuclear plant (Hinckley Point 3) which requires consumers to buy power at a price much higher than wind, solar, coal, or anything else. It was approved in the best traditions of corrupt government... advisers to government had a financial stake in it's approval. Also, the plant gives the Chinese access to French and UK nuclear technology and control over the plant... a win for everyone except the UK.
New records to correct mistakes are just fine. Going back and editing the blockchain is fraud. Anderson/Accenture know all about fraud so I can see why they want this. No, I don't trust them or anyone. That is why we have the blockchain.
They may be able to save a bit on the transport step if they can pull the train up to the H2 factory although you have to drive the train to the H2 factory. However, this only saves a few percent and still leaves a huge gap in efficiency between batteries at 70% and H2 at 20%.
If you'll read the references, you'll see that batteries are much cheaper. The equipment needed to convert surplus electricity to H2, compress it, store it, transport it and convert it back to electricity is much more expensive than batteries.
Just get a Chromebook. ChromeOS is Linux at the core and you can easily install Linux using Crouton and run it side by side with ChromeOS since they both use Linux.
Except Chromebooks are taking over. They run Linux at the core. (You can even easily install Linux using Crouton if you need programming, command line, Linux software, etc. It's fast since it uses the same Linux core. It runs ChromeOS and Linux side by side in a chroot environment. You can switch from one to the other with a simple hotkey command.) Hard for Microsoft to block Chromebooks.
cars + computers + network connectivity + bad security = bad You can't isolate yourself from the entire world. That's why we have locks on doors. Some people have strong locks, others don't need strong locks. Cars need strong locks. These security researchers did the right thing. They found a vulnerability, notified Tesla, and Tesla was able to fix it quickly and roll out the fix to its cars. That's the way it's supposed to work. All cars have a CAN bus which can control many things in the car. It needs a strong lock.

I use an HP LJ 4L (circa 1991) that I've had since it was new. It just keeps going printing like it was new. I use recycled cartridges ($10) about once a year.
People die every day by not paying attention in their cars. Tesla tells you every day to pay attention. If you don't, you could die. Some people can't follow simple directions.
Slashdot Mirror
These issues were raised by nuclear power experts.
The Chinese need to address them.
Baseload is BS. There is too much baseload. They give away electricity at night.
HP C electricity cost is twice that of the average electricity cost.

It defeats the purpose of having a blockchain if you can change it retrospectively.
It's not a blockchain if you can "edit" it.
Water?
I don't think it's mammals.
Burning massive quantities of fossil fuels could be a factor (it's in the FA).
Totally different beast. It might be useful but not as a competitor to Raspberry Pi.
Regardless of the energy density, H2 is still massively inefficient as an energy storage medium so it doesn't make sense to run anything on it.
They may be able to save a bit on the transport step if they can pull the train up to the H2 factory although you have to drive the train to the H2 factory. However, this only saves a few percent and still leaves a huge gap in efficiency between batteries at 70% and H2 at 20%.

H2 is very inefficient compared to batteries.
This diagram explains it in detail...

Bottom line, only about 20% efficient compared to battery 69% efficient.
