>What do you think causes viral pneumonia? Clue's in the name. A respiratory virus, of which there are many. >covid-19 variants are generally more contagious than the flu, so mask …

I don't think you understand how the maths works. The EROEI of nuclear is 106, by the link I previously provided. The very best solar installations have an EROEI of 7. That means n…

Not sure how you can say that, when almost every comment I've ever made to you has had some kind of calculation in it. Sounds like it is you who is attempting to dismiss arguments …

Just fine, if you're happy with approximately 1/4th the energy output for a given (manufacturing) energy input. And that's for the best case, for certain wind power installations. …

There absolutely is - it's called energy returned on energy invested.

I don't even care about the cost of the land, it's the mind-boggling amount of solar panels that would need to be manufactured to fill it. Have a think about how the panels would g…

I already did. We will never be able to find out how many people specifically died of Covid, and how many died of a viral pneumonia, thanks to the changes in death reporting guidel…

Do you really think that our current lifestyle is at all sustainable, without using nuclear power? So far, you have suggested that we build several 1000 square miles of solar panel…

Now there's where we get into interesting territory. The UK significantly relaxed regulations around March 2020, and basically made it very easy to put "Covid" on death certificate…

Fascinating argument, but unfortunately, we are doomed. That is, unless we go nuclear. Apart from that, there is nowhere near enough energy or resources to maintain our current lif…

Do you have a source for that? Assuming we use the hydrogen conversion process you mentioned, and have fitted the 1000's of square miles of solar panels it would need - I find it h…

Which will make fuel much more expensive, and thus less consumed (which is really what is needed). Obviously that will also mean poor people can't travel very far, but what are you…

Using the advertised final cost of electricity is, in my opinion, a useless way to work out the sustainability of any power source. It is skewed beyond usefulness by government inc…

Arguably the Amazon rainforest isn't competing with food supply, at least on a global scale. The UK has only just started reversing the almost complete deforestation it experienced…

Generating 500g hydrogen requires 25kWh (and a perfectly-efficient electrolyser would require 20kWh). One gallon of fuel has about 40kWh of energy available. To put it another way …

It's bogus that jet fuel can be renewable, at least in anywhere near the quantity we currently use. Mainly because the amount of arable land needed is staggering, and we already ar…

How much hydrogen do you need (eg, per final gallon of jet fuel), and where does that come from?

By "article", you mean "marketing blub from someone trying to sell you something". Ultimately, all of those "sustainable" feedstocks will have to be grown. As my quick maths points…

>They'd also know that pretty much the only condition we're treating nowadays is Covid. Do you have a source for that? The percentage of Covid patients in ICU wards in the UK peake…

The UK Government Covid death statistics literally say "deaths with Covid", and are defined as "deaths within 28 days of a positive test". So it is true, and always has been. https…

This is completely bogus. The ever-increasing global demand for soy foodstock is already accelerating the destruction of tropical rainforests - how is it all sustainable to burn hu…

Who gets to decide the "legitimacy" of a chain? Some document, or the participants?

Practically all of our "green" solutions rely on the fact that their energy-intensive manufacturing is done somewhere with lots of cheap (and polluting) energy sources. Show me a w…

How much electricity does this contraption need to generate, before it's accounted for its own embodied energy (that is, the power needed to manufacture it)? Probably more than any…

1. I absolutely hate the chatty style when it's used to spread the description of a js API over many tedious pages, let alone when it's used for a scientific subject like this one.…
