While these fuels power much of the creation of electricity around the world, as well as most transport and heating, they all need to either be left in the ground or 100% of their emissions. Below is a roundup of a group of articles of importance on these subjects.

Before Europeans arrived, Grizzly bears were relatively common in California, with an estimated population of 10,000, around 20% of the USA population at the time.

The car industry has done a great job over the last roughly 30 years, of confusing people. It was once the case, that there were 2 different states – the first cars were electric (so suggesting that modern electric cars are a new technology is ridiculous) and then we developed internal combustion engine vehicles. This meant that there were 2 different types of propulsion 1. fossil fuels (petrol, diesel) or 2. electric cars, charged from the mains.
Toyota developed the Prius back in 1997. At the time, a huge step forwards – it only had a battery of 1.3kwh, but this was enough to store energy recovered from braking and release it back, when the car was able to start moving again. This was the first mild hybrid as it is now called.

Sky islands are found across much of Africa. Our experience of sky islands, occurred within the Udzungwa national park in Tanzania. This national park protects a large portion of the Eastern arc mountains. – a chain of mountains which run across Eastern Tanzania.
Africa started drying out around 5500 years ago, and much changed at this point, including a great expansion of the Sahara. However, what is relevant here, is that in many parts of the continent, this caused the rainforests to retreat. More rain falls on higher ground, so you were left with a situation where the tops of hills and mountains remain forested, but the valleys become savannahs. Perhaps one of the most notable effects of this, was to split the worlds mountain gorillas into two populations, one in the Bwindi impenetrable forest in Uganda and the other in the Virunga ecosystem. At their closest point, these two protected areas are only 20km apart (though driving between the two are likely to take longer, as visitor facilities are not at these points). Unfortunately, this space between the two areas has a large human population. This means that the two mountain gorilla populations were stuck on their respective mountain homes, relatively close together, but with no way to cross the gap between.
Not researched until recently, there is a strip of mountains that runs from northern Mozambique to Malawi’s Mount Mulanje. As with the eastern arc mountains, rainforest was preserved on these peaks. These were finally given scientific attention by an internatiional team in the South East Africa Montane Archipelago study. While archipelagos are usually used to refer to a group of islands, it seems apt here. Among these mountains, there are around 30 fragmented pockets of grasslands and evergreen forests that have been largely cut off from each other.
This is perfect for housing unique collections of species, that have found themselves cut off from other habitat that they once roamed. This study, identified 90 species from amphibians(11), reptiles(22), birds(3), mammals(4), butterflies(39) and freshwater crabs(6), alongside 127 species of plant, not found anywhere else on earth. These sky islands are even being considered for their own ecoregion.
Big or small, it is important to protect these little ecological islands, and it should be possible to have tourists visit to give an extra income to locals.
Now the article (click here to read) goes on and on about this, talking about Musks previous perspective on Hydrogen, the roads being full of this future “stupid fuel” and how this might impact tesla future (suggesting dual fuel would be good – it did not help Toyota).
So, while this article came out in early November, the fact check that I have looked at came out in December (I am sure that there was an earlier one). Click here to read the fact-check but it is outlined below.
It is thought that the rumours came from various online videos and articles, with one specific piece frequently regularly cited. However, despite the fact-checkers tried to find this cited evidence, they were unable to find any about a Model H. Further more, large tech companies did not report this.
Given Elon Musk’s historic disgust on the use of Hydrogen in cars, it should take a lot of evidence to suggest that this was right. Furthermore, the suggestion that Tesla would have fully switched by 2025, rather than offering both is particularly ridiculous.
Is this false story good for Eldario24? Well, clearly it had a moment in the sun, but certainly I will not be bookmarking them. I believe that they should be punished for their behaviour.
Unfortunately, this is an article that does not need much work. Unless we find an insane quantity of hydrogen buried under the ground somewhere (and it would have to be infinite to really count), the question is, how much electricity does it take to make 1kg of hydrogen and how far can the car drive on it? If this is more than an electric car, then perhaps Norway has a point.
Continue reading “Norway has released an engine that runs on hydrogen – does this end electric cars future?”Who are these so called experts? What is there expertise in, and do other experts agree? Their expertise does not appear to have much backing it.
This engine weighs just under 11kg, and they believe that, as it delivers better efficiency and emission control, all within a sleek design. In the literature, so much is made of the efficiency of this engine, but that misses the point. They suggest that this efficiency closes the gap between combustion engines and electric ones.
This misses the point: electric cars are zero carbon at use. Therefore, the cleaner the grid gets, the lower the carbon will be. As such, it is all very well to compare electric cars now, to an experimental engine that will be in cars in a generation or two. However, in 2 generations, it is thought that most countries will have further greened their grid, leaving the electric car still ahead.
We drive an electric car, and as we pay our electricity company for 100% clean electricity, our carbon emissions are essentially zero (particularly, as we bought the car second hand). One could, quite rightly, argue that not all the electricity that we use comes from zero carbon electricity – instead, we use whatever electricity is being created at the time. But that is the point- our supplier buys enough zero carbon electricity to cover all our use, therefore, if they were supplying everyone in the country a 100% zero carbon electricity, they would have to buy enough green electricity for everyone. That could only be done by all the electricity in the country being green.
So, in short – suggesting an uber efficient small ICE engine used 10-20 years in the future is more efficient than an electric car driven on the grid now, is not a fair comparison. It is like comparing the price of apples now, to the price of futures in oranges next year. Do not buy into it. If every person in the UK drove an electric car, carbon emissions would be far lower, than if everyone drove the most efficient ICE car that has, or ever will be made (this seems pretty obvious, do not get hoodwinked).
Continue reading “So-called experts are claiming that the first ultra-compact engine which has just been unveiled, will be the end of EVsTransport roundup: cleaner cars and planes”In Finland, a so-called sand battery (it is actually full of crushed soapstone) has been built, which is capable of storing around 100MW of heat. The crushed soapstone is a by protudct of a fireplace production factory nearby. It is true that this heat battery is large, with a height of around 13m and width of 15m, but it can in theory be buried in the ground. It takes 2000 tonnes to fill this heat battery, but this is just 40 waste trucks worth.
It will serve as a thermal battery, with pipes running through it. It can be heated in the Summer when there is cheap or even free power, and then water run through pipes in the material can extract the energy in winter, powering a district heating network – greatly reducing the emissions from heating houses in the whole area (it is estimated that it will reduce emissions by 70%)
The Soapstone leftover, was a wasted product, and before was just thrown away, so this is a far better use. This “sand” battery can hold heats of around 500 degrees for months if required, and is thought to completely eliminate the need for oil in the network heating system. it equates to roughly 1 month of heating requirements in summer, and 1 week in winter. Costing around $200,000, compared to $1,600,000 for the equivalent lithium battery, it is a good deal. While it is true that it would take around 30 of these to keep the town going for a year and it only supports 100 houses and a public swimming pool, but there is huge quantities of similar waste created around the globe, and therefore is capable of doing far more than one would think.
Simulations of the same idea, in Seoul have suggested at up to 39% savings. It is thought, that as the deployment of solar increases, there will be huge amounts of excess power to be pumped into things like this. Some countries have wonderful quantities of excess electricity in the summer, and while we need to ramp up the quantity of solar wild and other zero carbon electricity, this gives us a route to a zero carbon world.
UK scientists created the worlds first diamond battery, capable of giving power for thousands of years. It is made from synthetic diamonds, which contain a radioactive element called carbon 14. The battery makes electricity from this radiation, much in the way that solar panels work. This battery would still be at 50% power after 5000 years. From devices that need powering in your body, to deep in the sea or in space.
At the end of their lives, these batteries can go back to the manufacturers to be recycled. There is much work being done on this, not least looking at other radioactive elements, to increase the power output.
Carbon nanotubes store triple the energy of lithium batteries. New research shows that twisted nanotubes can store high densities of energy – triple that of lithium weight for weight. It is thought that these could power things like medical implants. Of course, this is great, though only adds to the potential long list of things that nanotubes can do if we can learn to reliably create them in the future. In bigger sizes, it is calculated that these carbon nanotubes can store 15,000 times more per unit mass, than steel springs.
These are both areas which I write on, regularly, so check back for more news. I should also note, that these roundup articles should allow a return to focusing on wildlife rather than clean tech soon.

In 2024, for the first time, Tesla sold more cars than Audi – for many years, there were a large number of suggestions (from so-called experts) that Tesla was not a serious car company. Does this make Audi not a serious car company, or is Tesla finally a serious car company. Shares in Tesla fell last year as a result of the fact that they sold a small amount fewer cars than the year before, though Audi sales fell by 12% – while Tesla sales fell by 1%.
Suggestions that Tesla is in danger, seem far over stretched. It is true that it delayed its next car (the tesla model 2) but this delay is not likely to be long.
They are currently concentrating on the Robo taxi – it seems that share prices are ignoring the Robo taxi. In 2016 there was an estimated 18 million taxis on the road – given the smaller form factor, these are only expected to cost around $25,000-30,000. If they manage to revolutionize the production line (with their unboxed line) they are likely to be able to make huge numbers a year. It does require FSD to be cracked, so timelines could slip, but once cracked it is estimated that owners could make $40,000 a year (or more than initial investment)
For any readers who do not know what a pine marten is, the above will give you an idea. It is an arboreal predator (that is, it hunts in the trees). There are a total of 8 species of marten across the world. Historically, this was the second most common predator in the UK, with only the fox being more common.
Unfortunately, its habit of taking chickens lead to it being hunted ruthlessly. At the current time, it hangs on in Wales, and has a significant population in Scotland. In Ireland, the recovery is far further along.
In the UK, one of the reasons that we miss this little predator, is its impact on grey squirrels. Unlike the pine marten, the grey squirrel is not native to the UK, and its presence does much damage, from its impact on trees, and other plants, to the fact that it carries a disease which wipes out the reds rapidly (so they are incapable of living alongside each other). This is a species which I have followed closely, and while other matters have stopped me blogging on this species as often as I would like, it has not stopped me from reading about it, so you will find summaries of a variety of stories below.

Reintroduction project in Dartmoor: 15 pine martens were released in secret locations within Dartmoor in September. A total of 7 conservation organisations have been involved in this translocation. It is a total of around 150 years since pine martens were last in the area, but the translocated individuals are settling and slowly dispersing across the landscape.
To the right you will find a tiktok video which will give you details on this reintroduction.
@woodland_trust Pine martens are back in Dartmoor! 🎉  This conservation success story is the work of The Two Moors Pine Marten Project which we’re a partner of. 🌳  Site manager David Rickwood explains more. 📽  Learn more at 👉 twomoorspinemartens.org @National Lottery Heritage Fund  #woodlandtrust #wildlife #britishwildlife #wildlifetok #pinemartens #dartmoor #conservation ♬ original sound - Woodland Trust
While there is no idea where the pine martens came from, they appear to be doing well, and as the video shows, are breeding. While they have not been there long, so there is little evidence yet, it is highly likely that the pine marten arrival will be bad for local grey squirrel populations (a non-native squirrel which does much damage to UK woodland). This is an area of excitment and should be followed closely.
Pine marten caught on camera trap in Longleat estate in Wiltshire. It is unclear where this individual came from, lying half way between the forest of dean and the new forest (but far from both), but it is thought it has arrived naturally. While red squirrels would not be able to reappear in this part of the country, without help, as all surrounding areas have grey squirrels, should the pine marten survive, it is likley to greatly impact the local popualtion, and create an island, into which red squirrels could eventually return.
Pine marten were translocated from Scotland into the forest of dean, beginning in autumn of 2019, when 19 were introduced, and a further 35 joined them in the next 2 years. Last summer, there was an estimate of 60 living in the forest, which while not a big increase, it has not fallen.
While the forest of dean covers just over 200 square miles, it is thought that 60 is roughly the carrying capacity. That suggests that the pine martens in the forest of dean need roughly twice as much space as elsewhere, so time will tell if the population can grow beyond this level. Still, it seems likely that this number of pine martens should be able to eradicate the grey squirrel, or at least greatly reduce its number in the area.
The below video shows 3 cubs from around 4 years ago.

Research is being done on whether pine martens can live in timber forests – which account for a lot of forest in Scotland
Some simple changes may well allow timber and pine martens to flourish alongside each other. Across 1 woodland, a number of nest boxes have been added, which appears to be helping. The plantations are also looking at letting some older trees stay standing, as these are where cavities appear, which is the pine martens natural home. This research is being carried out in the forest of Ae and around Castle O’er.
Pine martens have turned up in a London cemetery, in area of England where they have not been seen for 150 yearsÂ
The Zoological Society of London ZSL (London Zoo)Â already had a project in the area with remote cameras, as it is a stronghold for the hedgehog (unfortunately, another species with a horrific decline in the last 20-30 years). It was just one (and this was in 2022, so may well be gone), but it is exciting that such a small area can house an animal like this.
The Forest of dean, is 80 miles away, which is the nearest population, so it is thought that this might have to be the result of an illegal translocation (they are being translocated, but should be done by professionals, with checks and more.
Pine marten recovery is further along, and helps understand how it will work in England, particularly in cities (not the safe zone once thought)
 Once almost extinct, for similar reasons in the UK (habitat destruction, and persecution) in 1976 they were given legal protection, and at the same time, forestry started to expand once again. The pine marten is how living in around 45% of Ireland.
The red squirrel is recovering as a result. There was a fear that grey squirrels would survive within cities, as pine martens are generally to shy to venture into even large parks within cities. However, what has been found, is that the abundance of squirrels in cities is a mirage – there are only sustained by populations outside the city, therefore, should places like the green belt around London get settled by pine martens, it is likely that the London squirrels would disappear within a few years.
Similar to elsewhere, pine martens have now also been introduced to the Lake district.
