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.

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.
Continue reading “Motoring body saying “UK needs to ban full hybrid cars by 2030 or face net zero ‘catastrophe’ (only cars that can drive on pure electricity)”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.
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.

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.
The problem with stopping deforestation, is that for the majority of the world we are far removed from rainforests (from where I sit in the UK, I would have to travel 3250km (over 2000 miles) to the nearest rainforest, which is an area on mainland India). Indeed, rainforest is generally something that only survives in developing countries.
This means that, for most people, they either live far removed from the rainforest, and so cant see it impacting them, or they live near a rainforest, but are struggling to provide for their family and those around them. It is quite true that many people in both the first and third world would like the rainforest to survive – indeed, should you talk to people in the west, many are very worried about the survival of the great apes, who are rapidly loosing land.
The problem is simple. Those living in the third world are living hand to mouth, so unless they work in tourism, the rainforest is often an inconvenience that makes life harder.
In 2023 a total of 6.4 hectares of forest were destroyed – more than 25,000 square miles. However, more concerning is the fact that 62.6 million hectares of forest (almost quarter of a million square miles) was degraded – for road building, logging, and forest fires. Degraded land is often less good for carbon storage, as well as conservation of the worlds wild species. It is often, then not long, before someone comes along a removes the rest of the plants so that the land can be used for something else.
And what was this deforestation for (other than logs)? Beef, soy, palm oil paper and nickel.
The Brazilian Amazon is one of the bright spots, where since the election of Luiz Inacio Lula da Silva, deforestation has fallen 62%. Unfortunately, in the same time period, Indonesia’s deforestation is up 57%
It seems hard to see how the world will meet its goal of cutting deforestation to zero by 2030 as most countries have pledged. Also, despite reductions in deforestation, the Amazon has had one of the hardest years in terms of forest fires – something that only gets more likely as rainforests are lost, and climate change increases the temperature in many parts of the world. It is a sad fact, that there is often not a great deal of temperature difference between a rainforest which is functioning, and one that dries out and becomes a fire hazard.
Having said all this… a study in Indonesia has found that controlled low-intensity logging doesn’t have to negatively impact a forest in terms of carbon storage or food availability – this in turn means that much wildlife can survive.
The problem often is that if the land is in private hands, then low- intensity logging is not going to happen. If the landowner has decided to deforest, they will raze the land. In national parks, in theory low intensive logging would be possible, but this would require people to control the logging, and this is the issue that we have in the first place. Unfortunately, despite the pledge by 140 countries, deforestation is coming back.
In a related subject, the Indonesian president Prabowo Subianto has stated that palm oil expansion won’t deforest because palm oil has leaves. There are many issues with this, but perhaps primarily amongst them, when forests are cut down, they are usually replaced with grass lands for grazing cattle – these are also covered in leaves. This is obviously stupid – it may well be a better thing, that the rainforest is going to be replaced with plantations, but it has been shown that palm oil plantations take up a tiny proportion of the carbon that rainforests take up.
In another article, there was a finding that macaques living in palm oil plantations have an alarming infant mortality. Unfortunately, these macaques are not unique in being threatened by palm oil, but others include orangutans, elephants, tigers, pangolins, bonobos, and Irrawaddy dolphins.
While palm oil may be a better vegetable oil than other crops, it still looks like it will lead to us loosing most of our rainforests, unless a grip on this is found.
I have spent a great deal of time, recently, working on a variety of areas of the website that I hope to become important in the near future (including members areas). During this time, I miss writing on these subjects, so I would open tabs on news articles that had caught my eye – when I turned my attention back, there were more than 1000 tabs. Several hundred are wildlife news, which I will deal with in the near future, but the rest have been grouped. There is a long video embeded in the bottom of the page, which gives similar information but in more detail, if you would prefer (produced by the electric viking)
This grouping is stories about Toyota, and its various moves which appear to clearly show their moves to make the climate worse not better.
Continue reading “Toyota was a climate hero in the 1990s, why is it now to exact opposite?”Wildcats are native to the UK, but have been pushed to the brink of extinction by hybridisation with native cats – which come from the wildcats from places like Israel in the middle east. As a result of this, as well as trying to remove the feral domestic cats, and their descendants, they are trying to create pockets of Scotland, which would allow these cats to recover.
The natural behaviour of a British wildcat when meeting a feral cat, is to kill it. However, as these animals become rarer, even rare breeding events, can threaten the survival of the whole species. This behaviour also means that with careful planning, we should be able to reintroduce them into other parts of the country. There are a range of other wild predators lost over the last couple of millennia – and I hope to see the others return, but it is thrilling to know that a wildcat is once again living and breeding in its native habitat of the Scottish mountains.
These wildcats are thought to be the first born wild in Scotland for 5 years, after 19 wildcats bred in the Highland wildlife park, were released into the Cairngorms national park.
This enormous temperature jump could have huge impacts. On 18th March 2022 scientist at Concordia research station on the east side of Antarctica. To put this leap in perspective, that would take a normal spring day in the UK, up to some of the highest temperatures ever recorded on planet earth.
Continue reading “World record temperature jump recorded in Antarctica 38.5”Having been released near Petersfield in the South of England, they will be tracked by a team of academics, to make sure that they survive and thrive.
These beavers will help with the rejuvenation of a wetland area on the river Meon. Currently, the area consists of a straight section of the river, with a sort of duck pond beside it, however, once the beavers get to work, this will change dramatically – turning the pond into a series of ponds, and making it suitable to house a wide variety of British wildlife.
As found elsewhere in the UK, the beavers are likely to have a rapid impact on water quality (for the better). A second pair were introduced to an estate near Basingstoke just last year (they had their first kits in September this year).
As in other parts of the country, these beavers will spread out from where they have been reintroduced (if allowed) and are likely to link up with other populations, such as the Devon beavers, within a small number of years – it seems likely that without a sustained attempt to remove the beaver once again, it is only a matter of time, before they spread to all parts of the UK.
Apart from the joy of knowing they are there, there are many positive impacts of their presence: they will reduce flooding (areas that they do flood with their dams, are places which we likely should not have built anyway), clean water and create habitats for many other creatures. Perversely, they have also been shown to help forests recover (by creating a mosaic of different habitats) and therefore should be a positive for the forestry industry in the UK, despite fears to the contrary.
