Economies of scale will continue to make solar panels cheaper. But changes in design and manufacturing also make them more efficient.

The early lecture theatre looks quite different to today's venue. Volta's battery was the first continuous source of electric current and started the modern electric era Davy discovered several elements by passing current through molten salts.

This is just missing a few yellow flames in the gas lamps and also a couple hanging from the ship. Little yellow highlights would offer a spot of appropriate colour

LED come in different colours and by mixing the primary red, green and blue LED you can create other colours. By generating colours we get a brighter purer light than using filament bulbs or carbon arc lights and coloured filters. I enjoy colour changing bridges at night

My morning rabbit hole. Our technology is like magic but instead of saying some incantation while waving a magic wand each part of this story pushes technological boundaries. Lots of hard work for each part. From sputnik in 1957 to today what a change we have seen

The picture in this post warranted a more detailed look. About 17 horses are shown but a group of them are pulling a steam engine. Does anyone recognise the painting and the subject? One figure looks like it has motion blure Or is this an AI creation?

For thousands of years our only source of artificial light was the yellow flame. (Or lots of them as in a bonfire) Electricity enables higher temperatures so lights become brighter and whiter. I know gas lit areas in our capital city that are looking beautiful at night.

What an extraordinary story. Aircraft only saved by being locked away and 'forgotten' rather than sold on or scrapped. In the UK taxation on commercial property would mean the owner would take the roof off. I do wonder if they had any WW2 searchlights.

Millions of consumers are paying a few pounds more on energy bills of which some are paid to these network operators soon accumulate to these huge sums. My brain copes with millions but billions look like this £4,000,000,000

In a thread on unusual bus stops this one sports bee attracting wild flowers and a solar panel. Fuel for bee powered flight and electric energy presumably to power displays of bus times.

Car parks around supermarkets, retail parks, and other similar places are ecological deserts with a few token tree avenues along the paths. One even has plastic grass around the edges. I can think of no better locations for solar canopies to shade the cars.along with a battery

Of course someone owns the collectors, and then the bulk transmission and then the local distribution and billing. A bit like water where the rain falls giving us free water but it costs me circa £400 /yr for the stuff coming out of the pipes

I was only reading Michael Faraday's book on the chemical history of the candle last week. Enjoyable for the science but also as a record of his Christmas lecture at the RI It was how people used to speak in the 1860's

We have lost all of our public electric supply power stations from the Victorian era. Let us at least keep one set of these

This post led to an uncontrolled chuckle

~45% of US corn production is now used to make ethanol, mostly for mixing into gasoline. That's ~13% of all US crop land already used for energy production. Using some of the same land for solar panels would capture 50-100 times more energy per acre.

"Palace" is trending on twitter due to the team name winning in football If the Victorians can build an impressive crystal palace with iron and glass then we can easily recreate it but even better This is an excellent idea and if we start now we might just manage to do it in time

The thread below was my morning waking up screen read. The Ferranti Deptford power station had sudden changes in load. Long cotton rope 'belts' linked the steam engines to the generators and the elasticity of the rope helped stability before inertia systems.

France has passed laws requiring all large car parks to be covered in solar canopies. Car parks are ecological deserts apart from an odd token tree. Outside supermarkets who could use the power so no grid charges. Why cannot we follow their lead? solarstoragextra.com/closura-offers…

Robots to speed up solar construction in Saudi Arabia. When you have hundreds of thousands of panels to install robots can do the work instead of humans suffering in the extreme hot climate solarstoragextra.com/robots-to-spee…
