Digital Cameras: Crop vs ‘Full Frame’

December 27, 2017 January 10, 2022

There are cases where the rapid evolution of technology means that terms can lose connection with their original meaning. ‘Crop’ and full frame are clear

Humans: the species with accessorised evolution.

The defining difference between humans and other species is that the "accessories" we make evolve independently of our genes. The difference between humans of 50,000 years ago and the 21st century can be seen by anyone while birds' nests, beavers' dams and bees' hives only evolve when the species evolves.

In the spirit of Batman and Ironman, our 'accessories' or 'tools' allow to outcompete other species confined by biological evolution and provide humans with enhanced abilities that could even be seen by past generations as superpowers. Genetically we may be similar to humans of over 50,000 years ago, but our accessories make us very different in ways that impact us from our population to tolerance of others.

Cars, Trucks & EVs: Can the EV save the car?

This is the lead webpaper on cars and trucks and their future, which mostly focus on the transition to EVs and hybrids but also the future of car ownership. Many, even including Elon Musk, claim that in the future, people won't need to own a car. I suggest that sentiment misses that which makes car ownership more compelling than just having a method of transport. In fact, this is potentially headed in a same direction where it could also be suggested "people won't need their own home". This is a site that supports a transition to EVs, not begrudgingly and only provided EVs are only ever smaller city cars or better still just electric bicycles, but because EVs should allow the vehicles we want to own to be sustainable. That is provided we don't also succumb to living in cities that seek ever denser population densities.

BYD now targets Toyota: DM-i goes global in 2024 with BYD Seal U Dm-i & BYD Shark.

Commenced: January 14, 2024 Updated: April 23rd, 2024

2024 April 23 th: Updated to second edition, with some fixes and completions.

BYD led with the world's first PHEVs in 2008 in China. Having taken the sales lead in China from VW, BYD began to get serious about global markets in 2022, but initially seeming to target the EV market. As of 2024, rather than wait for the world to migrate to EVs, they are now launching their DM-i plug-in hybrids that are crushing gas-powered car sales in China to the world. This page looks at how BYD "DM-i" plug-in hybrids work what's different from other hybrids to make them to being to "pure EVs" than most people realise, and will track details and specifications of BYD export DM-i PHEVs as they reach new markets. In the last 3 years, BYD went from as far behind Tesla in EVs as they are now behind Toyota in hybrids to catching Tesla. If they can provide DM-i at ICE vehicle prices and less than Toyota ICE based hybrid prices, then just maybe in another 3 years they can catch Toyota.

Software and tips for BYD Atto 3 + other BYD EVs.

2024 April 9 : Updated the "software updates to request" list.

Although this page was launched with information on side loading Apps to the BYD Atto, it is progressively being updated with more tips for BYD Atto 3 owners such as charging and battery care. For those considering buying an EV or other content on the Atto 3 and on BYD can be found on other EV pages on this site. Rather than a typical webpaper, this page is really only of interest to owners of BYD vehicles. See page contents dropdown for an index to this page and a list of what is covered.

Tesla vs BYD: Market competitors or duopoly?

Commenced: April 20, 2022 Updated: March 1st, 2024

2024 March 1 : Update in progress.

Is Tesla or BYD the world's leading EV maker? They both are! While who leads depends on over what period and how you count EVs, together they dominate world EV sales, and their combined position is strengthening. So, no undisputed world number 1 EV brand, even at year end 2023. These two are the current EV market leaders, and as EVs gain market share, these two are on trajectories to become no #1 and no #2 car carmakers worldwide when EVs take over, if no legacy brand passes them. But will either of them ever reach true #1 before the chasing pack catches them? This page reports and tracks progress.

Decades long EV transition with no green quick fix.

Commenced: June 9, 2022 Updated: February 5th, 2024

2024 Feb 5 th: Revised introduction synopsis and transition acceleration calculations.

Despite many claims that EVs have a dirty secret in that they are not really green at all, the real secret is how long it takes for the green payback. The claims are based on two realities: 1) the driving of EVs still results in emissions when EVs are charged from our current dirty electrical grids, and 2) the building of EVs also creates emissions, and sometimes increased emissions over building ICEVs. However real data from critical studies shows that even in the worst case, overall, an high build emission inefficient EVs charged from a dirty grid still result in less emissions than ICEV. Just in that extreme case, only a marginal reducing in emissions! However, already not all grids are "dirty grids" and as vehicles have an average lifespan of over 20 years either dirty grids will improve during that 20 years or we may have bigger problems. Build emissions from EVs largely track EV prices, and Wright's law dictates both EV prices build emissions will soon fall below those for ICEVs. The real conclusion from examining this question, is there is no quick fix green EV transition, but any delay in reducing production of ICE vehicles is creating …

What’s needed to profitably make vehicles, and are only Tesla and BYD there yet with EVs in 2023?

Commenced: November 28, 2022 Updated: December 18th, 2023

2023 December 18 th: Updated "franchise/dealership problem"

Why is it so hard to make money from making EVs at a competitive price? This is an exploration of the profitability challenges, and the answers to "Do only Tesla & BYD profit from EVs?" and "Why make vehicles at a loss?". Auto makers must either 1) find a way to make EVs at profit, 2) close down, or 3) hope there will still be a large enough ICEV market for them to survive. Highly funded research indicates that in future just 5 EV brands will dominate 80% of vehicle the market, and the reality is only one of the top ten automotive brands from 2021 is a likely contender.

BYD. Who is BYD and “what’s next from BYD?”

Commenced: June 15, 2023 Updated: December 6th, 2023

2023 December 6 th: added "What's next for BYD exports" section.

Depending on how you count, BYD is either the biggest, or 2nd biggest, EV brand in the world. But that is only the start as BYD ranks not only compared to Tesla and other EV brands, but in total of ALL vehicle sales. In August 2023 BYD overtook Ford to secure 4th spot in global car sales. In China, the world's largest vehicle market. BYD has now in 2023 taken the lead from VW and Toyota as the bestselling brand of all vehicles inside China. No Chinese brand has ever been market leader in China before, and this not just of EVs but all sales including diesel and gasoline vehicles, despite BYD snow selling only EVs. As of March 2023, the Atto 3 from BYD has risen to 3rd bestselling EV globally behind the Tesla Model Y and Model 3, but the world outside of China is only just starting to see the capabilities of BYD and quality of their vehicles and batteries.

Hydrogen facts: No, it’s not abundant on Earth. Nor green nor an energy source, but energy storage.

Commenced: April 13, 2021 Updated: December 1st, 2023

2023 December 4th : New edition of this page, with additions including white and pink hydrogen and more on the pressure required for storage.

There is much talk of a 'hydrogen economy'. A hydrogen future has long been the dream of the fossil fuel industry, and much of the traditional automotive industry, but what is the nature of the element hydrogen that is behind it all? There are clear practical uses for hydrogen, but the questionable hype is the use of hydrogen as a fuel or in energy storage. It turns out much of the attraction around hydrogen fuel is that it can generate a value chain for suppliers as it more expensive than alternatives and could provide a revenue future for the fossil fuel industry, if only a reason to compel its adoption despite the cost barriers. This is a look at hydrogen itself, its abundance, and the blue and green etc sources of hydrogen, as background for pages on hydrogen cars vs EVs, on carbon capture, and for this page highlighting which "hydrogen projects are viable, and which are scams?"

RCS – The SMS successor and blue bubbles vs green culture war.

Commenced: August 15, 2023 Updated: November 26th, 2023

2023 November 26th : Apple RCS adoption announcement.

The world and usage of SMS has moved on since the introduction in 1992, and the system lacks many features now seen as essential, including even the ability to see if a message has been received. Apple has its own proprietary "iMessage" SMS/MMS successor for communication between iPhones within the Apple walled garden and the bubble wars, Facebook has its own messages system and has "What's App", but is there room for a true SMS successor that is not a walled garden fully controlled by one technology company to create division into "tribes", and instead is able to connect all devices just like the original SMS system? RCS is simple to enable and is the best messaging solution for Samsung and other Android phones and to end culture wars and walled gardens.

Why EV Battery size is not just about range, and the implications for hybrids.

Commenced: April 13, 2023 Updated: November 1st, 2023

2023 November 1 st: full page revision.

When you look deeper, battery capacity of an EV matters far more than you might think, as it effects not just range, but also battery life and vehicle power. If a battery is quite small, as is usually the case with a hybrid (HEV), and even most plug-in hybrids (PHEVs), there will be limited total distance that can be driven "emissions free" before battery degradation, which is why use of fossil fuels is a necessity for most hybrids.

Living with an Atto 3 EV in 2023: An Australian Experience and FAQ.

Commenced: September 25, 2023

This page began as a 'Should you buy an EV or not?' written from experience, but as it is impossible to cover every possible perspective, the example is an Atto 3 in Australia, so the more similar the vehicle being considered is to the Atto 3, and the more similar the country to Australia the more of this content that will be of interest. For comparison with other vehicles, I have a separate page soon to be published comparing the Atto 3 to both other EVs as well as traditional internal combustion or hybrid vehicles.

Once the darling of Hollywood in the wake of "green" image built by the Prius hybrid, Toyota has more recently prompted shareholder complaints, and calls for boycotts by climate groups in response to Toyota anti-climate action and anti-EV lobbying that has seen the company reach the status of no 3 climate enemy company in the world, behind only Exxon-Mobil and Chevron. Either Toyota is ideologically against action on climate change, or senior management see no way for Toyota to survive the EV transition.

Now for something not Covid-19, which is a rarity lately! A different topic for this blog, but 5G came up in a recent conversation, and what I thought I 'knew' about 5G was: significantly higher mobile data rates were possible (true) 5G is based on higher frequency radio than 4G etc (false) 5G works for far more people even in a crowded spaces (true) towers for 5G must always be close in order use 5G (false) 5G data rates could potentially match/replace fibre optic cable (false) As you can see, turns out what I had thought prior to research, was all a collection of misunderstandings, but when I did research, I found more conspiracy theories than facts.

EV Price-Parity: It’s here already – sometimes, and EVs are setting sales records in key segments.

Commenced: October 19, 2022 Updated: March 19th, 2023

2023 March 19 th: Revised "proof is in the sales" and "whats-here".

There already are some EVs with not just "Schrödinger's parity", but genuine price-parity winning not just awards, but topping sales charts. These are mostly from the Tesla and BYD duopoly, but they are not entirely alone. Beating ICE vehicles in sales chart is the best test for price-parity, and segment by segment, EV contenders are being launched. Yes, there are still many overpriced 'token EVs' that either exist to satisfy green requirements, provide products for brand loyalists demanding EV products, or help convince their makers "there is little demand for EVs". This is an evaluation of price parity, and a list of vehicles with price parity on the market. The previously subsidy free Australian market is the base, but with inclusion of key international. The implications for established brands, and brand loyalty were surprising.

5G, Wi-Fi 7 (WiFi), Bluetooth & UWB: Why do we need them, and how do they all fit?

Commenced: January 5, 2021 Updated: March 4th, 2023

2023 March 4 th : Updates for WiFi 7.

I recently researched 5G, in order to understand what it was all about, and the reality of any possible new health risks. I came to the conclusions that 1) health risk claims are groundless, and 2) there is no logical reason to upgrade devices at this time to get 5G. But that research led to questions on how all the connectivity standards fit together, and how compelling might it be to upgrade devices to get benefits of new Wi-Fi, Bluetooth or UWB?

One pedal driving, lift-off regen and regen braking explained: reality, myths, hype, fads and Tesla vs the rest.

Commenced: May 12, 2023 Updated: March 3rd, 2023

2023 Mar 3 : Updated steer by wire.

Update in progress. To make sense of all the often seemingly conflicting information on "regen", one-pedal-driving, and how to best drive an EV, it can really help to understand that in most EVs the regenerative braking is fully integrated into the braking system and the two different regen system in use in EVs can suit two very different driving styles: 1. Lift-off regen: In all EVs and like engine braking in an ICEV. 2. Brake-by-wire regen, an additional regen system in most EVs. Confusion over these two systems is part of regen confusion, but there are many myths and so much misinformation about regen-braking, lift-off regen and one-pedal-driving including that "one-pedal-driving" is not the most efficient way of driving, and that the regen you feel from lift-off is not all the regen. Despite the fact there is so many myths leading to so much misinformation making it sound complex, driving an EV for optimum efficiency is usually extremely simple.

Tracking Legacy Car Brands Fall as EVs Rise.

Commenced: March 8, 2022 Updated: February 28th, 2023

*2024 Jan: Statistics update for VW, Mercedes, BMW,

We are in a time of disruption by electrification as planes, trains and automobiles, as well as shipping, all move to zero emission power. But it is the EV disruption of car industry that will have the biggest impact on consumers, and EVs have become "real" and desirable much sooner than many brands expected or wanted. New players such as Tesla, BYD and others will become the new leaders, and together with the globalisation of the EV centric Chinese car industry, combined, will take at least 50% of the market. So, what happens to the existing big brands of the legacy car industry sharing the remaining 50%? Either half die out, all halve in size, or some combination of both! The EV disruption will catch out many legacy car makers, with the shift skipping the anticipated interim step to hydrogen vehicles. There is a separate webpaper exploring why it is so difficult for legacy automakers to make a profit from EVs, and this page will track major 'legacy' brands through the transition to see which, if any, survive, as the new brands increase their market share.

The two speed EV transition: Manufactures vs consumers. (part 1)

Commenced: February 26, 2023

It is easy to underestimate how long it will take consumers to transition to EVs, and equally easy to underestimate how urgently manufactures need to transition to avoid collapse. Two transition speeds? Yes, brands will switch to EVs in their showroom by 2025 or risk failure, but in what seems like a complete disconnect, there will still be internal combustion vehicles on the road past 2050. Around 10.5 million Electric Vehicles were delivered in 2022, which resulted in less than 0.7% of Internal Combustion Engine vehicles (ICEVs) being replaced by EVs during 2022, even those EVs represented 13% of new vehicles sales. The data shows that new car showrooms transition to EVs 20x faster than the roads, and vehicle manufacture transition 20x faster then the public, and while ICEVs will likely still around beyond 2050, vehicle makers that can't switch fast enough could collapse by 2030, bringing radical economic change.

EVs 2023: Is Tesla losing its cool as BYD ascends?

Commenced: January 13, 2023

The world of EVs is changing, as is the leadership. Tesla lost 50% of its valuation in 2022. Some are predicting it will lose half of the remaining value in 2023, and although others predict the stock price will rebound, both outcomes are possible, and which becomes reality could depend very much on whether Tesla can remain 'cool', or through Musk and twitter becomes linked to far right. Although entire EV future is not dependant solely on Tesla, a decline could have wide implications, for the market, competitors and the global transition to EVs. Not only are the 'legacy' automotive companies GM, Ford, VW and Toyota competition for the hearts and dollars from consumers, but also BYD, who is already taking the EV lead from Tesla. Keys factor in EV trends during 2023 could turn out to be who is 'cool', shifting perceptions of a climate threat and the need for rapid response, and the impact of conflicts such as Ukraine. Rapid radical change for the industry, but it will take longer to impact consumers.

BYD Atto 3 / Yuan Plus: The first 3rd wave EV arrives in Australia, and then the world.

Commenced: April 23, 2022 Updated: December 6th, 2022

2022 December 06 : Awards and sales results so far.

The Atto 3 (or Yuan Plus) is not only EV giant BYD's, first global car, has now become the 3rd largest selling EV globally. Launched as BYDs first global model and the first 3rd wave EV for the west, already outselling Tesla vehicles and #1 selling EV in some markets, the Atto 3 could even challenge to become the world's top selling vehicle. While BYD has exported cars before, the Atto 3 is based on the "global focused" e-platform 3.0, and with a more significant launch into larger markets than previous BYD tentative exports, should spearhead the international push of the world's largest new energy vehicle maker.

Surviving with an EV and no driveway: on street charging.

Commenced: November 20, 2022 Updated: November 20th, 2022

2022 Nov 20: First version.

People have for decades owned cars without needing to refuel at home, so it may not seem obvious just how important home charging is for owners of EVs. Various surveys confirm that 80% to 95% of EV charging happens at home and given that less than 80% of people have access to a space to be able to charge at home, those who can't charge at home are less likely to buy an EV. To understand the problem, try living with a mobile phone without charging at home, or at work.

EVs can be divided into 3 waves: EVs that people can use despite limitations including the Tesla Model S, Nissan Leaf, i-MiEV, and Zoe. Then EVs are truly competitive in premium and enthusiast markets: Tesla Model 3, then Model Y. Mainstream EVs at the Tesla Model A/2 price point, but so far from China, not Tesla. While China has been another world for EVs, with price competitive EVs from US$5,000, only now in 2022 is the rest of the world getting its first 3rd wave EVs, and so far, they all come from China. Teslas were sold globally, but every other EV, was either an EV not sold in China, or a Chinese only EV. Two separate worlds of EVs, that have begun a hurried unification and bring 3rd wave EVs and automotive industry disruption to the entire world.

*2023 December 10 th : Updated market data in introduction.

After friend told me "I am not interested in electric cars, because I will wait for hydrogen cars", I did the research, and found that such a future no longer makes any sense and will never happen. It turns out that hydrogen cars were never desirable and only viable if EVs remained impractical. Hydrogen vehicles have now been surpassed for charge times and range and they were only ever anexpensive to build and operate, higher emissions, limited interim stop gaps, for the time until we reduced the limitations of battery EVs.

EV Battery swapping: Recharge or Refuel?

Commenced: March 20, 2022 Updated: July 16th, 2022

*2022 Aug 17: Link to NIO swap vs XPeng fast charging

There is a full exploration of recharging electric vehicles on another page, but there is an a "refuelling" alternative to recharging: battery swapping. With electrical appliances in the past, when the batteries went flat, we swapped them. Then rechargeable batteries became popular so we could avoid throwing out the old batteries, but I swap first and then recharge. It turns out, we can also do that with cars, and it is happening already. Battery swapping, take only around 5 minutes, but so does recharging the latest batteries. Battery swapping will likely play a key role in the future, but not necessarily the role many expect.

EV range: Anxieties vs realities & needs and the “real-world range” myth.

Commenced: November 10, 2021 Updated: June 1st, 2022

2022 June 8: Initial restructure, added range optimisation section on getting the best range.

This is a look at range, covering from how no one number accurately describes an EV's range and driving the full range of EV outside of emergencies just wastes time, through why range is so unlike that of fossil fuelled vehicles and optimising range is all about efficiency, through to what range a person needs around the town or for highway driving. Range with EVs is such a different experience that novices can feel anxiety, despite that in practice running out of charge in EVs happens no more than ICE vehicles run out of gas. While EV range is getting closer to ICEV range, most EVs, unlike the Lightyear One pictured here, aren't solar and most EVs still don't match the range of internal combustion engine cars for highway driving, but the convenience of background charging means range with EVs is usually only a limitation on relatively rare road trips.

EV Range & Economy: Decoding the Numbers.

Commenced: May 1, 2021 Updated: May 24th, 2022

2022 May 24: added link to article on WLTP range is really calculated.

The key specification for EVs so far has been 'range'. But how are the numbers measured, will range specific match reality, and can the number even be compared? It turns out there are even 3 different standards for measuring range, and they give very different answers! Further, why have we moved from 'economy' to 'range'? Is there still even economy with EVs?

The electrical grid, V2G and EV Home Charging: Missing an opportunity for the planet.

Commenced: February 26, 2022 Updated: March 15th, 2022

*2022 Dec 16: Fully charged

Move to renewables for energy, and electricity for transport, and we solve the climate problem. But renewables require storage, and uptake of EVs requires home charging, and there is a cost to both. But what if electric vehicles could solve the "green power grid" problem, provide energy security, and avert a threat of increasing inequality, and reduce costs? It turns out this dream scenario is definitely possible but can be fully realised only if the home charging problem is solved.

Personal Mobility Advance: Unagi Model One Electric Scooter. Unagi Model 11 Mystery.

Although the Segway did not deliver that new era, it is possible he was onto something that is gradually becoming a reality. This is a look at how far the Unagi E500 model one electric scooter advances personal mobility, and what broader steps technology has made towards personal mobility.

2022: Year Of The EV take over, and beginning of the end for the ‘Legacy’ Industry.

By the end of 2022, Electric Vehicles (EVs) will be the choice for the majority of all new car buyers worldwide. In practice, while Asia and Europe will see EVs at over 50% market share, delivery in some key markets where EVs currently have around 5% market share to around 20% by year end, but the end of the internal combustion engine will clearly be looming. The motor vehicle industry, sales and servicing, will see upheaval with the majority of current players headed forced close or sell out.

Hydrogen Future or Fool’s Gold & Scams: “Where does the hydrogen come from?”

Commenced: October 24, 2021 Updated: October 24th, 2021

*2023 May 17 th: Updated synopsis and revised.

The race to stop CO2, has led to many 'scam' projects involving hydrogen, but it is not always clear who is being scammed: the public, or the proponents of hydrogen projects. What is the attraction behind the obsession with hydrogen? This is a look at the motives, the myths and the facts around hydrogen projects. Spoiler: There are some valid roles for hydrogen, but hydrogen has no remaining role as an energy source, and even any potential role as an energy carrier is highly questionable.

The US military is, for the first time, sharing that they really do have UFO/UAP sightings that they cannot explain. It is easy to underestimate the significance of this revelation. There is even at least the appearance of deliberate efforts to downplay the significance. But this revelation, at some level changes our understanding of the universe. Every possible explanation sounds crazy. All of them. Yet at least one explanation must be real.

Electric Cars: 2021, EVs Just Don’t add up (yet).

*2023 December 10 : Reformatted without content change.

Right now, without subsidies, buying an electric car does not objectively add up. Currently there is a price premium, and as a result EVs only appeal to those happy to pay a premium to indulge a passion. Some buyers are prepared to pay a premium for the environment, "the future" or the acceleration, but right now, buying is driven by passion and/or subsidies.
