Earlier generations of Nest didn't have proportional control capability of any kind, no ability to apply Load or Temperature compensation either which are things that less polished looking heating and cooling control systems have been

Ireland has very hard water for the most part so I don't think that'd be the reason.

In fact, on (2) this isn't even something an exchange can do through their Ts&Cs. Local law will decide creditor priority so in the absence of a regulatory framework that treats exchanges as "bank-like" and makes, as a mi

Hydrogen is extremely easy to store underground. It is expensive to make (i.e. inefficient and capital intensive) and to move around with compressors but actually storing it if you have access to salt domes and depleted gas fields is not ha

Those don't exist. What's the point in just making things up?

The challenge here is at what point in your life is one making the gamble to live in the US vs Western Europe? If I had to pick one or the other to be born in, but knew that I would be born randomly within each of these societies, I'd

Strangely, not very much.

Historically, the UK has not had much gas storage capacity (even Rough wasn't that big) because gas wells have a reasonable amount of turndown capacity and those wells are directly coupled through St Fergus and other sites into gas cle

"King Charles III had just taken the throne last week when one Caribbean leader floated the idea of doing away with the British monarch as his country's head of state." This is sloppy reporting. Browne has previously made cle

I think part of it is the problem space to be honest. SAP basically gets used to glue all the fiddly bits of organisations together and I don't know that there is an approach to that set of problems that doesn't get tangled up in

Essentially. The CO2 cooled AGR has much lower power density and was thought by its designers to be a much superior design to water cooling for safety and cost reasons. It turns out, definitely not on cost grounds and the AGRs are all reach

Ironically all but one of our UK reactors are carbon dioxide cooled although to be fair that carbon dioxide is then used to boil water.

On the other hand, basically every complicated bit of engineering on the PWR is due to the fact that it does have such a high volumetric power density. A PWR is basically a fancy (very fancy) pressure vessel which is cheap (in relative term

"Which is a problem considering how small the H2 molecule is: we can't reuse our existing LNG pipelines." Assuming you mean natural gas pipelines, this isn't the case everywhere. Many flexible seals and ancillary equipme

It's actually both better and worse than you think. Better in that many places which have comparable population densities on a national level like the UK or Italy are mixtures of villages, fields, and forests with substantial areas of

I liked it. It is cherry picked but I think that doesn't affect the value of the book. Essentially the point of the book is: "it used to be uncontested that all human societies in the past functioned in a particular way and mo

You're right that its explicitly identified that way but that's because it isn't obvious, if it was obvious they wouldn't have needed to be explicit about it. For example, retreating soldiers are absolutely still combata

This story is specifically about West London, which is not the EU but I'll grant you has similar settlement patterns. More than two thirds of car owners in the UK have access to off-street parking. Many people who do not have such acce

The impact of domestic chargers with smart charging enabled (now mandatory) on maximum demand after diversity is not very large because they almost always end up charging in the middle of the night. Public chargers have a much bigger impact

Grid connection, land use permissions (i.e. local planning). The latter is very easy in rural Texas so just the former really.

Is it? People seem to think that planes are fancy and new and trains are old technology, therefore it's absurd that flying is cheaper. If you think about all the infrastructure that needs to be built and maintained for high speed rail

It's built into the meters based on a hardware ID code, so any particular meter will only accept a certain set of highly sensitive operations on particular days. So if you need to shut off Mrs. Miggins for non-payment (not legal to do

The author mentions demand charges where a substantial part of the bill is based on the peak capacity available to you at the most congested time rather than energy unit charges. In many places, large customers already pay this way. In Fran

The GB grid has half-hourly pricing for retail customers (with a cap and floor to prevent exposure to full wholesale risk i.e. not like those Gridly clowns in Texas).

The architecture of the GB smart grid only allows any given meter to be remotely disconnected on certain days. This is to make it impossible for an attack to disconnect more than a fraction of all meters with any one attack.

Samples are concentrated, then cultured in L20B (mouse cells with polio receptors added) and human rhabdosarcoma (RD) cells) to screen for either non-polio enteroviruses (very common). Samples which are L20B +ve (i.e. likely have polio) are
