UK English slang is a wonderful thing My wife has been here 30 years (she's American) and she still scratches her head and needs some of it explained....she does know that if she has to ask she's probably going to end up rolling her eyes and saying ewww, disgusting!!

Just because you can trace your maternal or paternal line back to some dude who pitched up in North America 400 years ago it won’t mean you are some pure bread Norwegian / German or whatever. Every time that ancestors kids have married or had kids that dilutes your ancestry by half. I’m no geneticist and I’m probably over simplifying things but after 12 generations you might have 4000 ancestors. I did one of those tests and I’m Northern European / Scandinavian and English. It’s an interesting thing to do, and I’m forever getting emails alerting me to people I’m related to but they are in the main extremely distant relations with a tiny percentage of common dna. I’d be interested to take another test from another provider, I’d best you don’t get identical results. These companies don’t give much info out on how they classify genetic geographical groupings.

Glad she is OK, and hope this hasn't knocked her confidence. That your kid has been knocked off must be about the worst think you can hear as a parent, can't have been much fun for you either.

Im just loving my garage heater Might even get another one so I can be extra toasty out there ... bloody freezing outside though and I still have 20 tons of leaves to clear up.

I'd love to see some snow down here, although I changed my car in the summer and the new one will be bloody useless on snow ... so be a good excuse not to go to work

They are bloody brilliant. I was wondering if I could wear mine whilst skiing , need to rig up a 12v battery to run it as it works off the bike

Clearing up leaves today, making a huge bonfire and making sufficient smoke to annoy my neighbours. Needs doing every few days at this time of year. Had to change the belts on the leaf sucker half way through, they dont seem to last very long. I did get out for a bit later, nice and toasty in my heated under jacket thingy.

Surely to get sufficient energy density for practical storage for refuelling its going to have to be stored at massive pressures, which must take a ton of energy in the compression process? I have cylinders rated to 300 bar and they are pretty chunky, I'd imagine you are going to need to go a long way beyond that to make it practical.

I realise that, I have an electrolysis machine which generates one H and 2O's from a given volume of water, but it uses lots of electricity to do it. In an electric car one uses clean power (mostly) to charge the thing up and off you go. There are transmission losses in getting it from generation to point of use, around 10% but it depends on lots of things so could be less. The electric motor in an electric car is around 90% efficient. Overall transmitting and using electricity in a car is pretty efficient. For an H car again you need to use electricity... to produce H gas, then you need to liquify it. H needs to be cooled to circa -250DegC to liquify it, process which uses over a quarter of the energy in the H to achieve. Then you need to transport it, still at -250C and store it, still at -250C (I assume?) until it goes into a car fuel tank as gas. The fuel cell/ engine is more efficient than an ICE engine but less so than an electric motor. I think they are 60% efficient? So you lose a big chunk of the energy to make the H then liquify the stuff, then store it, only to use it in an engine which itself is about 60% efficient...or am I missing something here...?

Ah OK, they must just pop down to the lake of hydrogen at the end of their garden to grab a jugful then.

I wonder where the hydrogen to run it comes from in the first place.

Sorry to hear that, it’s heartbreaking to go through. Make his last day a really happy one for him.

Thanks, it's so sad that they have such short lives. He passed away in my arms last Monday but I keep expecting to see him come into the room, and then I remember. I still get broken up about it. I hope yours gives you many more years of love.

Give him/her a hug, every day. I lost my dog after almost 13 and a half years last week, Im still heartbroken about it.

You've got the right username. Glad you survived....
