A couple of kids wrote a science book about Tesla & EVs, by kids and for kids
A new children’s science book about Tesla and EVs, Everything Tesla: From How They Work To How Fast They Go And All The Fun In Between!, launches today, written by twin 9th graders Aiden and Eliana Miao, and targeted at kids between the ages of 8 and 13.
Aiden and Eliana are from Palo Alto, California and spent the last 4 years assembling the impressive tome, which was originally going to be 20 pages long but swelled to over 200 pages as they researched and wanted to add more to the book.
The authors say that they wanted to inspire kids to learn about science and electric cars and to care about the environment. They say that their parents’ Model 3 inspired them to think about climate change, along with wildfires and smoke days that have increasingly become a feature of California summers and autumns as climate change continues to worsen.
For their research, they read and watched a number of EV news sites and Youtube channels, including us here at Electrek (hi kids!). They pitched us over email and frankly, it was one of the more professional pitches we’ve gotten, and the book really impressed us when they sent us a copy.
Eliana says they also held meetings with professors and engineers to fact-check their writing over the course of the 4 years of work they put into this book (more than a quarter of their lives working on one book? they’re veritable George R.R. Martins).
After years of writing the book and being met with a significant amount of rejection from adults, Aiden and Eliana found an editor, Alexander Cox, and a designer, Sadie Thomas of LS Design, who helped them turn their idea into a real book.
The book is exceedingly well-realized (way beyond what we expected when we read their initial pitch email – Stanford, keep an eye out for these kids’ college application when it comes in), with full-page graphics on every page and quite a lot of information.
Everything Tesla largely focuses on Tesla and Tesla-related topics, though a lot of these points are generalizable to other electric cars, like how electric motors work or dispelling battery-related myths, or to related topics, like sections on solar panels and climate change.
The book as a whole is written in language that is accessible to young audiences, but still has a wealth of information that could probably teach some adults the basics about electric cars. The authors think this might be the first kids’ science book written by kids and for kids. Or at least, they couldn’t find any others in their own search.
While the book is not endorsed by Tesla, it does adopt a very positive view of everything related to the company. We here at Electrek also appreciate Tesla’s leadership in the EV industry, but our praise for the company and particularly its leader might have been a little more moderated than what you’ll read in the book.
Nevertheless, this is a much more impressive effort than, uh, anything I’ve ever seen a 9th grader do. Kids these days, am I right?
Everything Tesla releases today, is self-published and is available on Amazon in Kindle or hardcover versions, and at Books Inc in Palo Alto. The authors will have a book launch event at Books Inc on March 23rd at 2pm, and are excited to give an author talk next week at their old elementary school, where they attended when they started writing the book.

InMotion, a well-known brand in the world of personal electric mobility, has officially launched its latest electric unicycle, the InMotion V9. Combining advanced technology and new safety features, the V9’s design positions this electric unicycle as a key option for urban commuters and adventure seekers alike who want good performance without spending a fortune.
Believe it or not, the electric unicycle market is quite broad. There are dozens of interesting models, offering everything from slow, beginner-friendly wheels to massively powerful and scary fast off-road electric unicycles (EUCs).
The new InMotion V9 launches as something of an in-between wheel, providing enough power and speed to keep it fun and interesting, yet without going so over-the-top that it becomes unaffordable or unapproachable by newer riders.
Priced at $1,299, the InMotion V9 is powered by a 1,000W motor that can reach peak outputs of 2,000W. This setup delivers a top speed of around 28 mph (45 km/h), positioning it well for urban streets and bike lanes, two of the most common stomping grounds for EUCs.
Range anxiety isn’t just a concern for cars; it can also affect micromobility riders. For its part, InMotion gave the V9 a fairly hefty 84V and 750Wh battery. This capacity allows the V9 to achieve up to 37 miles (60 km) per charge under optimal conditions. The UL-listed battery charges fairly quickly, reaching full capacity in approximately five hours.
One key feature of the V9 not found on most beginner-friendly wheels is its Nimbus Air suspension system, which provides 60 mm of travel to enhance rider comfort and reduce fatigue on uneven surfaces.
The included suspension is even more notable considering the V9 is currently InMotion’s lightest suspension-equipped electric unicycle, weighing around 48.5 lbs (22 kg). And speaking of weight, the EUC can support riders weighing up to 265 lbs (120 kg).
The InMotion V9 doesn’t skimp on smart features, either. Its integrated GPS tracking enables owners to remotely locate and monitor their unicycle via InMotion’s mobile app, even when powered off. Remote locking functionality further enhances security, ensuring peace of mind for riders frequently leaving their wheel unattended.
Additional smart integrations include customizable RGB side accent lights and built-in Bluetooth speakers, allowing riders to personalize their ride and stay entertained while commuting – or just keep cars and other road users more aware of their presence. The V9 also includes USB-A and USB-C ports with 20W output to ensure riders can conveniently charge their mobile devices while on the go.
Safety is always paramount in electric transportation devices, especially those that come with their own unique concerns like electric unicycles. The V9 has TÜV Rheinland UL2272 certification and “advanced fire-resistant technology” to mitigate risks further.
The InMotion V9 is now available for purchase through local InMotion dealers and via the official InMotion online store.
I don’t cover electric unicycles as often as e-bikes, scooters, and other micromobility devices, but not because they are less deserving. They’re certainly more niche, but I know that the EUC community is adamant about their advantages. And listen, I get it. They’re small and convenient to park or store inside, they don’t require much maintenance at all, and they’re pretty fun after you get the hang of them. An EUC can be intimidating at first, but once it clicks in your brain after a few learning sessions, riding one is a blast!
With the electric unicycle market continuing to gain traction, InMotion still faces competition from other premium brands. However, the V9’s comprehensive package of comfort, safety, and advanced smart features, combined with its competitive price point, should place it pretty well in the crowded landscape of personal electric transportation.

Fremont, California-based Delta Electronics just rolled out a sleek new 50kW DC Wallbox charger that’s designed for tight spaces at ACT Expo 2025.
This charger packs a punch in a surprisingly slim, 10-inch-thick, and lightweight (just 225 pounds!) casing that can be wall-mounted or set up on a pedestal. It’s specifically designed for tight spaces like urban parking lots, busy corporate campuses, or crowded fleet operation hubs.
Delta plans to manufacture these 50kW DC Wallbox chargers in Plano, Texas, keeping it local and supporting the rapid EV infrastructure growth across North America.
A 50 kW charger is at the low end of Level 3 fast charging speed, because you don’t always need to charge your car in 25 minutes. It’s the ideal charging speed for shopping, lunch, or seeing a film. Eng Taing, Delta’s senior VP and GM of energy & telecom Infrastructure, says, “Our focus is on seamlessly integrating high efficiency charging into the diverse scenarios of everyday life, including commercial operations, not just maximizing power output.”
With a 97% efficiency rate, the Wallbox can juice up two EVs simultaneously using either CCS1 or NACS connectors. Plus, the 23-foot cable makes it easy to accommodate nearly any parking layout, eliminating headaches during installation.
Delta’s vertical integration approach means it handles everything from design to manufacturing. But it doesn’t stop at hardware; the charger also connects to Delta’s IoT platform, offering remote diagnostics, predictive maintenance, and over-the-air updates. That hopefully means fewer disruptions and smoother operations for fleet managers and EV users.

More car buyers are hunting for used EVs – CarMax says searches filtered by “electric vehicle” have nearly doubled since January 2022.
CarMax saw EV searches surge in March 2022 and again in June 2024. The first spike lined up with the gas price shock after Russia invaded Ukraine, and the second came right as the Biden administration rolled out its $4,000 federal tax credit for used EVs.
The online used car marketplace’s Spring 2025 Electric Vehicle Consumer Report shows just how far used EV prices have tumbled, down over 40% between January 2022 and February 2025. By comparison, prices for gas cars, hybrids, and plug-in hybrids only slipped about 12% over the same period.
The top 10 most popular used EVs
For the third year running, the Tesla Model 3 and the Model Y were in the No. 1 and No. 2 slots, respectively, from September 1, 2024, to February 28, 2025. The Chevy Bolt jumped into third place from its previous spot at No. 7 in 2024 and 2023. The Ford F-150 Lightning (7) and the Rivian R1T (10) made the top 10 for the first time, while the Tesla Model S and the Audi e-tron dropped out. The Hyundai Ioniq 5 and Nissan Leaf were at Nos. 5 and 6, and the Volkswagen ID.4 (4), Nissan LEAF (6), and the Ford Mustang Mach-E (9) made the list for the third year in a row.
What people are trading in
For the first time ever, more people are ditching sedans and coupes for EVs than SUVs. CarMax says sedans and coupes made up 44% of all EV trade-ins, up from 36% in 2024 and just 29% the year before. It’s a clear sign that the EV switch is picking up speed across more than just SUV drivers.
When customers traded in sedans for EVs during this report’s measurement period, the most common EVs they purchased were the Tesla Model 3, Tesla Model Y, and Chevy Bolt EUV.
The top traded-in model for an EV at CarMax was the Tesla Model 3, and those who traded in a Model 3 usually went for a Model Y. The rest of the top five include the Honda Civic and Accord, the Nissan LEAF, and the Toyota Prius. The Ford F-150 truck, the top trade-in alongside the Accord in the 2024 report, dropped off the list.
Where used EVs are most popular
Since this is CarMax’s report, it’s of course based on data sourced from its 250 stores across the US. In 2025, Oregon beat California to become the state with the highest percentage of EV sales compared to each state’s total sales at CarMax. California has previously held the top ranking since 2023.
The West Coast continued to dominate when it came to used EV sales. California and Washington were in second and third place, respectively. Nevada and Arizona were fourth and sixth, while Utah and New Mexico (new to the top 10 list this year) held spots five and seven. On the East Coast, New York (10) appeared on the list for a second time, dropping two spots from No. 8 in 2024.
The newcomers include Minnesota, which jumped 24 spots in a year to No. 8, and New Jersey, which moved up six slots to No. 9.
