Aaahh - but is there enough dense matter in the head to simulate a pressure-cooker explosion?

I wouldn’t call this a goldfish nibble Grumpy… it’s more like a shark bite to the side!

That brain-dead shark in the other thread you mean...?

What they simply do is to reverse the combustion process (or electrolysis, etc.), and produce (or recover) fuel.

This is possible, but to achieve it you will need an efficient energy source, which in the case of sunlight is not an efficient one.

Sunshine is however free at source. The key point is whether the total cost of the process is more or less than that of producing by other means. an equivalent amount of fuel with the same energy value,.carbon foot print etc.

That's irrelevant if you cannot utilize it effectively. How much sunshine is needed to run a car for 100 miles?

Indeed. It is however not a matter of how much sunshine or wind or moving water one has but what else is needed in terms of land, labour and capital to turn these free resources into something we can use.
