> Tattoo pigment particles are quite inert. Asbestos is quite inert, which is a good property for fire retardant materials to have. However it does have an unfortunate effect when inhaled.

EDF has only recently become fully state owned. Also the French state have recently amended the ARENH arrangement to get greater revenues (who knew selling options for 42 EUR/MWh was a bad idea). Greater losses and damages have been in

It is a good job the station's Finnish owner/operator, TVO, got it on a fixed price contract. That does not make coping with the delays in coming online any easier, but some consolation that someone else is footing the constructio

I understand that such a capacity metric might be useful for generation, and somewhat useful for storage. One could see the grid operators having a good grip on the utility of storage to smooth off tv pickup and evening peaks, in full knowl

Well, I've eyeballed the capacity of the storage in the system from the graph at around 25 to 30GWh. The CAISO website does allow downloading per-day CSV files of the 5-minute power on a per-day basis. There is also the question of beh

The article seems to mix storage capacity and instantaneous power. Lithium batteries tend to be able to discharge their stored energy in perhaps 1 to 4 hours (for instance the Tesla Megapack is between 2 and 3 hours to discharge). Yes batte

I believe that offshore wind formed a key part of the vision for the United Kingdom's net zero transition. They wanted to use the learning curve to become the "Saudi Arabia of wind power", manufacture hydrogen etc. https:&#x

Indeed, the selling point is probably that a single entity can build an SMR without risk of going bankrupt. Perhaps this speaks to the problem of building consortia of like-minded companies. Currently EDF are being stung for a large chunk o

You can produce significant fractions of a large modular reactor (e.g. AP1000) in a factory. There are arguments that for a small modular reactor the civil works that happen onsite (e.g. foundations) could make up a larger proportion of the

I'm not sure that nuclear is that expensive per unit of energy delivered, compared to rooftop solar for instance. In Europe (UK and Germany) one might get 1000 kWh/year from 1kW of panels. Last year I helped a family member instal

Ontario gives hope to the nuclear dreams. Being able to deliver projects on-budget gives decision-makers cause to believe project plans. Lets hope that another 4-pack of CANDU reactors will be built, to further the soverign industry.

CANDU are a great design; the calandria is a nice adaptation to the capabilities of Canadian maufacturing, and it is impressive to see the lines of reactors at Bruce, Pickering and Darlington. It is also a widely exported design, with China
