Comment "Smaller than a hair" - no (Score 1) 15

If you read the article carefully, they are talking about lenses THINNER than a hair. I see several of the posts here thinking the width/radius of the lenses is this small, a reasonable mistake given the way this was written. Having a radius that small would severely reduce their light gathering ability, requiring very bright light or very dim images or very long exposure times.

Comment Still not impressed (Score 4, Informative) 105

Germany has squandered over half a trillion euros on Energiewende, and to show for it they have the second filthiest grid in Europe, has some of the highest electricity costs in the world and still relies on coal. Half a trillion euros could have bought dozens of gigawatts of clean and reliable nuclear capability.

I live half-way up the UK at about 54 degrees north. My panels produce virtually nothing between late October and mid February.

This year has been unusually good for solar production but it usually peaks when I don't need it. Will probably look into getting a battery, though despite how I keep hearing about how cheap they are now someone needs to tell the installers.

Comment Here's an idea... (Score 1) 72

Instead of trying to get battery and hydrogen power to work, buses can collect electric current from wires strung above the road. This will make the buses lighter, more efficient, safer and enable them to run all day and night.

I've even come up with a name for them: "Trolleybuses".

I also thought of a more advanced concept where these electric buses run on rails set into the road but I don't want to start a revolution here.

Comment Re:Renewables supplying 15.2% of UK electricity no (Score 1) 63

More wind is not the answer as the intermittency and storage problem will never be resolved. Adding more will just lead to an over abundance on sunny and windy days, with a massive deficit on cold and still winter nights.

The UK and most of Western Europe experienced near nil wind from August-November 2021, the output would be the same if you had a thousand turbines or a hundred thousand.
