The maths are simple.. The Solar constant ..ie the energy from the Sun at local noon on a surface normal to the rays close to the equator is 1kW per sq metre. It drops away off noon ,in cloud and at different latitudes .. but not as badly with latitude as might be expected. A quality solar cell...

That's a no brainer.. Of course there will be taxes on the use of electric cars. Whether it is a yearly return on the odometer reading .. which is my preferred method , or a massive cost on the MoT or NCT as we call it , the State needs its revenue. All jt requires is the inclusion of a small...

I hope the Op went well.. . Having a heart will be a genuine improvement. In my case sticking metal bits around the one I was born with has not done me harm.

Thank you for including me in a debate in which I have consistently avoided. British internal party politics is an internal matter and has zero interest for me. If I am interested in buffoonery, I have plenty of more local targets.

I think we all have our tales ... Like bringing a caravan through Snowdonia in Wales but having the jockey wheel interfere with the automatic brake , so all the braking was due to the car ... . Or bringing the same caravan on the coast road between France and Spain , near Coillures, with the...

But you see it might not be as heavy ...if it were a hydrogen FC with a very small battery. The huge problem with a caravan is the parachute effect .. the wind resistance will play havoc with any estimate of range.

Nice one Flecc.. yes I got my taste for France from caravanning , but I was coming to the same conclusion anyway. We would be on the roads looking at streams and stream on coming caravans and wondering ...what are they coming from. ? What do they know we dont know about the place we are going...

I don't doubt that. However in my case, I have already absorbed the capital cost of my Diesel, It has a very low resale value, and putting a towhitch on a new car would absorb a lot of thst. , there is no major advantage in road tax ... And we don't do congestion charges or free parking. Motor...

If you read back, I was not carrying a flag for the Prius, what I did say was even with the extra baggage it was carrying, the electric motor bit brought the efficiency comparable with other cars of its vintage. I always thought that combining both motors via a gearbox ... electric and ICE...

Hey!!. That is called moving the goalposts. A Fuel cell system feeding a battery and a motor from a source of fuel, is exactly as much a hybrid as a ICE , driving a generator feeding battery and motor, from a source of fuel ....and that is where I made my initial posting.

I am comparing the 15 year old Prius technology with the 15 year old Automatics it was in competition with. Can you not keep a train of thought for longer than a post?. And no. I currently drive a 10 year old Peugeot 3008 Diesel , bought from new , which is actually ideal for my needs. It has...

The new PEUGEOT e-EXPERT Hydrogen includes a new mid-power plug-in hydrogen fuel cell electric system, specific to STELLANTIS. Based on the EMP2 (Efficient Modular Platform), the new PEUGEOT e-EXPERT Hydrogen is a fully electric vehicle, combining two on-board sources of electrical energy. The...

The Prius against the petrol engine automatic transmission cars of 15 years ago is the comparison . The only materials required for an electric motor is aluminium, steel and a ceramic bearing material.and an insulating varnish. Copper and Aluminium can be interchangeable. Rare earth elements...

Nope .. and you call yourself car buff?. The current and earlier hybrids use a complex gearbox arrangement to feed the ICE power into the wheels and also electric motor power into the wheels,and also the ICE energy into a battery. So in so far as it is heavy, it is, inefficient yes ..but even...

No it is not ridiculous at all. The ICE is most efficient when running at a fixed speed into a optimal load with air flows optimised. . It is running it into a load which is varying and at varying speeds which is wasteful and requires a complex gearbox, clutch etc. ..all of which add weight...

That is as maybe. But holding politicians to account is always useful. If they realise that what they do might well be scrutised 9 months later, they might be more circumspect in their behaviour. Otherwise the tendency is to behave like a St Augustine .".with a God give me the gift of Chastity...

As is my practice, I will not be commenting on individual British politicians, however I would strongly disagree that it is not time for a review of what the UK did wrong with CV19 in the March to October 2020 period. . You might be taking slight comfort that the current daily death toll in the...

Not very subjective. The figures are there in the tables dates of initial infections.. . Contrast that if you will with our acting Taoiseach who was on the annual junket to Washington , who two days previously held an utterly unprecedented press conference on the steps of the Observatory in...

No Zlatan, there were contingency plans in existence, and it is the PRIME responsibility that of the Government,to direct the resources of the State. If you go back to our musings of mid March , we were very clear of the failings. And yes We in Ireland have skin in this game. Our infections...

It also depends on your age... As a youngster, the teadium of the hard seat and the cold and dreariness was palatable, in the company of mates, and was acceptable if it meant saving up for a home deposit but one becomes more intolerant of creature discomforts ..and in my case extremely...
