This is factually wrong; rare earth elements are not required for batteries. Rare earth elements are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), pra

This links to something that's occasionally interested me. Are you able to consciously refocus your eye? By this I mean stare at an object (with one eye), and consciously make it go in and out of focus, whilst always staring straight a

1.2GW, 120km off the UK coast. The UK currently (Jan 2016) has ~8.5GW onshore wind, and ~5GW offshore, so Hornsea 1 is a significant addition :)

Good to see this happening. Grid-scale electrical energy storage/peak-removal is definitely something that needs to happen before the move to 100% non-fossil-fuel is possible, and electric vehicles can play a worthwhile role here. I pl

Diesel is essentially a hydrocarbon, so water and CO2 can provide all the elements required. The normal problem is that the cheapest/easiest source of hydrogen is from the stream reformation[1] of natural gas, but here there are using

The Green Party are extremely unlikely to achieve a majority vote in the election, but it's just possible they'll be involved in a coalition. It'd be exciting to see what happened if a policy like this is ever talked about

I can't find a reference now, but as I understand it this isn't so much of an issue at low pressure. Apparently underground low pressure storage has been used successfully: http://en.wikipedia.org/wiki/Hydroge

I was wondering if these could be used to store hydrogen generated by solar water-splitting? Could the hydrogen be piped in place of natural gas? Or combined with natural gas? seemingly "town gas" was primarily hydrogen [1]. Or it

They mean GW. Many news articles on this subject show irritating ignorance of energy/power and the correct use of units :( GW per hour would be the rate of change of power generation, which is obviously incorrect given the context :)

Garbage collectors have no problem with reference cycles. A GC works by finding all objects that are reachable (referenced by some other object or a root), then discarding all other objects. So a cyclic data structure is completely discarde
