You have still got it wrong. It not cards but a digital ID. It's in the name!

Why does the New Scientist continue to laud phony science?

Pumped storeage like Dinorwic was always the best option. France followed our lead when we with little corporate memory forgot.

Your headline is false physics. Their analysis using a scattering matrix with an imaginary component of the wave merely recalculated Snells law with a slower velocity in the medium. No time delay is imaginary compared to the incident wave it is a real delay.

It was irresponsible vandalism by the conservative government to eliminate the fledgling UK ID card system in 2011 destroying all records. This voluntary system would be mature by now and we would be consistent with most civilised countries in the world.

The relative level has stayed within errors to the same value for more than 20 years and only shows that as the nation gets richer, the statistic is constant. You need a different statistic to make what I believe is a valid point Res Foundation!

Where is the diverse connection to the national grid for such an important facility. Single point failure is unacceptable. This, imo shows that Heathrow's owners have not considered this vital design flaw in their resilience planning.

Time is defined as a series of sequential events and is fundamental whereas space emerges from a timely universe.(Smollin) As we can never know or measure what is outside our universe the answer is that the time in our universe started at the Big Bang. QED

The IPPR should know that in all the categories they quote, we do not produce enough ourselves, so there is no more to export. Take energy for example, we have been a net importer in all sub categories of energy since 2005!

I still ask why the CEO of Serco has not responded to this 'topsy-turvy world where a government contractor, Serco, can fail and fail again', so we'll put by the Guardian today.

The story was run on Radio 4 Today and surprisingly they didn't ask the CEO of Serco the tag provider to explain their lack of service delivery for which we are owed. Another of their failures!

And if we are to support green steel then Port Talbot is ideal for a true SMR sized plant.

Good article but pity you couldn't spell Berkeley correctly!

Enrico Fermi, Emilio Segre to name but 2

The trouble is that electricity is not a competitive market. My point is that electricity should be priced in relation to the bulk price not the cost of the last kW on the grid as it is now. By this way we would get the economic benefits of renewable energy.

It has nothing to do with grid infrastructure but is down to the 2014 energy act so the price is set by the most expensive fuel on the system which is gas.
