World first UK prototype could pave the way for constant energy all the time – from space

Building the solar power ‘farm’ in space would take more than 60 rocket flights, possibly with SpaceX, and a team of robot builders. The power would be directed away from inhabited areas, probably offshore. Whether the finance numbers would add up is anyone’s guess, but it’s claimed to be a lot cheaper than nuclear power for example, with no waste product.

A company hoping to launch the first solar farm into space has passed a critical milestone with a prototype on Earth, says Sky News.

Oxfordshire-based Space Solar plans to power more than a million homes by the 2030s with mile-wide complex of mirrors and solar panels orbiting 22,000 miles above the planet.

But its super-efficient design for harvesting constant sunlight – called CASSIOPeiA – requires the system to rotate towards the sun, whatever its position, while still sending power to a fixed receiver on the ground.

Network Rail hopes staff will be ‘amateur meteorologists’

Among the latest excuses for train service disruption are problems caused by ‘heavier rain’ and more ‘extreme weather’, due to the catch-all climate change. Storm frequency is called ‘unprecedented’ but such claims lack substance without detailed historical data.
—
Network Rail is aiming to turn hundreds of staff into “amateur meteorologists” as part of plans to deal with the effects of climate change, says BBC News.

It wants to help staff to interpret weather forecasts to make better decisions during storms or heatwaves.

The public rail body said it will spend £2.8bn over the next five years on efforts to cope with extreme weather.

Its boss Andrew Haines said climate change was “the biggest challenge our railway faces”.

Is it time to abandon the idea of phasing out oil and gas? – asks Saudi oil boss

Can oil bosses be blamed for pointing out real world facts and calling for a ‘transition strategy reset’? At present, wind and solar energy contribute just three percent of the global energy supply, and developing countries can’t afford, and/or don’t want, to have to rely on renewables for power as demanded by climate obsessives with big ‘carbon footprints’.

Despite feigning interest, Big Oil still appears to oppose the global green transition and could well stand in its way, says OilPrice.com.

As Saudi’s state oil company leader condemns the green transition and calls for long-term oil production, other major industry players are voicing their scepticism around renewable energy and clean tech.

Despite large investments into green energy and carbon-cutting projects from several oil and gas majors, Big Oil still appears to be heavily favouring fossil fuel production.

First Ever Advanced Reactor Submitted for Justification in UK

Press release – the application ‘has been accepted for Government consideration’. Electricity supply is too important to be left mainly to erratic and weather-dependent power sources.

LONDON, UK – 5 April 2024 – The Nuclear Industry Association has applied for a justification decision for newcleo’s lead-cooled fast reactor, the LFR-AS-200, says newcleo.

Our application makes the case that the benefits of clean, firm, flexible power from the LFR-AS-200 would far outweigh any potential risks, which are in any event rigorously controlled by robust safety features, including passive safety systems, built into the design and incorporated into the operating arrangements, in line with the UK’s regulatory requirements.

The application also demonstrates that the reactor design would support nuclear energy’s contribution to a stable and well-balanced electricity grid, which is essential to reduce consumer bills and maintain economic competitiveness.

Need for a rethink of ‘the critical role’ of atmospheric dust in Earth’s climate

It seems ‘classical dust cycle models have over-estimated the amount of dust emission.’ This in turn affects the results from climate models, which ‘have only been providing a fraction of the story’. This ‘has significant implications’ for reconstructions of past climate.

You may think of dust as an annoyance to be vacuumed and disposed of, but actually, on a grander scale, it is far more important than most people realize, says Phys.org.

Globally, dust plays a critical role in regulating our climate, radiation balance, nutrient cycles, soil formation, air quality and even human health.

But our understanding of it has been hampered by limitations in current mathematical models. These models, built on methods developed decades ago, struggle to accurately simulate the properties and quantities of dust.

Simple equations clarify cloud climate conundrum, say researchers

The paper, Weak anvil cloud area feedback suggested by physical and observational constraints, says in the section headed ‘Implications of uncertainty’: ‘A rigorous assessment of the anvil cloud area feedback was lacking because the confounding factors of cloud overlap and a changing cloud radiative effect on the feedback could not be accounted for.’ However, in the article at EurekAlert we find: ‘New analysis based on simple equations has reduced uncertainty about how clouds will affect future climate change’. A somewhat mixed picture there. The chicken/egg climate/clouds ‘conundrum’ remains.

Clouds have two main effects on global temperature – cooling the planet by reflecting sunlight, and warming it by acting as insulation for Earth’s radiation.

The impact of clouds is the largest area of uncertainty in global warming predictions.

In the new study, researchers from the University of Exeter and the Laboratoire de Météorologie Dynamique in Paris created a model that predicts how changes in the surface area of anvil clouds (storm clouds common in the tropics) will affect global warming.

Scientists unlock the secrets of sand for revolutionary energy storage

Sand batteries ahead? It’s no secret that sand holds heat quite well.
– – –
Have you ever raced across a hot beach and noticed how warm the sand gets?

That simple experience hints at a powerful idea that could change how we store energy, says Knowridge.

Researchers are now looking at heated sand as a promising solution to store energy for the future.

Unlike the batteries we usually think of for storing energy, this method offers a new and potentially game-changing approach.
