San Diego International Airport may be the home base for an enormous amount of emissions from all the airplanes flying in and out of there, but the airport itself is becoming one of the greenest when it comes to its electricity supply.
San Diego International Airport is working with San Diego Community Power (SDCP), a not-for-profit community choice energy program, to get 100% clean, carbon-free, renewable energy supply. The airport is signed up for the Power100 service, which means that SDCP will provide it with 100% renewable electricity.
This new partnership means that San Diego International Airport is switching to 100% renewable electricity almost 15 years early, as its target was to achieve this milestone by 2035.
“Having the opportunity to work with San Diego Community Power enables us to reach our goal of 100 percent renewable electricity well before our planned timing of 2035,” said Kimberly Becker, San Diego County Regional Airport Authority President and CEO. “SDCP’s ability to provide reliable, zero-carbon energy at competitive costs is a gamechanger for us and everyone in the region.”
“As one of our first Power100 Champions, we hope SAN’s choice will inspire additional businesses to upgrade to 100 percent clean energy enabling us to reinvest even more in the community,” said Bill Carnahan, Interim CEO of San Diego Community Power. “As a local not-for-profit, all of our excess revenue will be invested locally in workforce development, job training, aid for communities of concern, and training and employing local workers.”
San Diego Community Power indicates that it offers Power100 service and PowerOn service, the latter of which provides 50% renewable electricity supply, but there are not many Power100 customers yet.
San Diego Community Power will start offering renewable electricity packages like these to residents in February 2022.
Two other things also worth noting: customers can opt out of the service at any time, and all power delivery, billing, and customer service still goes through SDG&E.
“Throughout June, approximately 72,000 commercial and industrial accounts in San Diego, Chula Vista, Encinitas, Imperial Beach, and La Mesa will become customers of SDCP; a public energy agency committed to providing clean energy, competitive rates, and innovative programs,” the organization adds. Though, San Diego International Airport is likely the biggest customer to date. “San Diego International Airport (SAN) is the busiest single-runway commercial service airport in the U.S. and the third busiest airport in California. In 2019, SAN welcomed 25 million passengers and offered nonstop flights to destinations worldwide. The airport is an economic driver for the region, contributing nearly $12 billion in economic activity in 2019 and supports nearly 116,600 jobs.” To go 100% renewable for its electricity is a commendable, important, and hopefully influential step forward.

Weird Alibaba: An inflatable Chinese electric jet ski for $2,000 – What’s the catch?
As usual for entries in this Awesomely Weird Alibaba Electric Vehicle of the Week column, the fun EVs we dredge up tend to bridge the gap between fun-looking and palm sweat-inducing. Would you take a cheap inflatable electric jet ski out into the bay or off the coast? What if I told you that you had to build it yourself?
That appears to be the case here with this week’s find. It’s an inflatable vessel that is jet ski shaped, though I’m not sure it fulfills all of the requirements to become a jet ski – namely the water jet turbine.
In fact, there’s actually no motor at all. It seems to be just the 3.5 meter (11 ft) boat itself, but at least it comes with a convenient transom in back to mount your own motor.
And in our case, we can slap on an electric outboard to turn this thing into not just a bad idea on water, but a green bad idea on water.
If you really wanted to stay true to the advertising, you could actually get an electrically powered jet ski-style water turbine to add to this boat. Amazon can hook you up with an impressive offering that looks like it would require cutting an inlet hole in the bottom of the boat and an exit somewhere through the rear transom.
Short of building a true jet ski though, I think an overpowered trolling motor will probably suffice. The vendor for the motor linked above seems to propose that is equivalent to 10 hp, which sounds reasonable for a small watercraft like this.
Technically the motor is only rated at 2.2 kW, which is around 3 hp. But we generally find that small electric outboards offer performance of around 3x the rated power of combustion engine outboards due to their much higher torque. It may not rip as fast as the larger gas engine below, but then again maybe it will. Who knows until we find out ourselves?!
You’ll need a whopping 60V of battery for that awesome little electric outboard, which I’m hoping will fit either under the seat or under the “hood” of the jet ski.
I’d actually be pretty interested to get a look under that hood to see what’s going on with that steering wheel. Since the jet ski/inflatable boat seems to be set up for a transom-mounted trolling motor, I don’t know how they expect to tie in steering linkage to something like that.
But my past experience of buying electric boats on Alibaba has taught me to never discount the ingenuity of East Asian engineers building low-cost vehicles that will presumably hold the life of one or more people in their hands.
One thing is for sure: At around $2k, this will definitely be the cheapest new jet ski you could buy, electric or otherwise. Personal watercraft aren’t cheap, and the electric ones carry a significant premium.
But if you’re handy, don’t mind wiring up a motor and battery yourself, and also don’t mind a steering wheel for show while you twist around to control a tiller motor, then you just might wind up with one of the most unique vessels on your local lake or river.
And consider the ease of transport! You probably don’t even need a trailer like you would for a traditional jet ski. The entire thing weighs just 176 kg (388 lb), though the spec sheet also says it is made from fiberglass, so perhaps the data isn’t quite accurate. Either way, this inflatable vessel can’t weigh too much. And the fact that you can deflate it to fit in the back of a van or SUV is a big benefit too. Or you can just leave it inflated and probably fit it in a truck with the tail gate down. Not my mini-truck, but maybe your truck.
At $2,025 for this thing, it’s pretty darn cheap – though that’s before the cost of batteries and a motor. Don’t forget though that there’d be several thousand dollars in shipping costs, customs import charges, taxes, broker fees, etc. Also, don’t forget that you should absolutely not buy this thing. While I’ve picked up some cool and weird little EVs from Alibaba over the years, it’s never a good idea. The process is long and complicated, not to mention fraught with extra charges at every step of the way. And you never know if the company who just received your wire transfer is even going to deliver your product in the end, which is just another fun little stressor that comes with shopping on Alibaba. So please, don’t join the ranks of my foolish readers and risk your hard earned money on something weird like this.
But if you ignore my warnings and decide to go for it, be sure to let me know what happened! And maybe update your will before the maiden voyage.
Here are the best April Fool’s jokes from the e-bike industry this year
April Fool’s Day, celebrated annually on the first of April, is usually a light-hearted and mischievous occasion marked by good-natured pranks, hoaxes, and jokes. Large organizations often take part in hoodwinking others, creating an atmosphere of amusement and (hopefully) harmless trickery. Sure, it’s annoying when you fall for it. But it’s also humorous to see what companies can come up with next. E-bike companies and the larger micromobility industry often have fun getting in touch with their inner prankster (remember the pedal-powered popemobile?!), and this year was no exception. These are some of the fun and light-hearted new announcements from around the electric biking and micromobility world.
We’ll keep updating as we find more, and feel free to send me any you find today (contact info in my author blurb below the article).
Magnum’s human-powered bike
Here in the e-bike industry we are often so deeply focused on the latest batteries or the most innovative new motors that we can sometimes forget our roots. Magnum Bikes, a popular electric bike company, wants to make sure we all remember where we came from with the “launch” of its new human-powered electric bike.
Called the Navigator Infinite, Magnum says the bike can get over 100 miles (160 km) of range. I guess “infinite” truly is at least 100!
Muc-Off releases intimate lube
Muc-Off is a brand of bike cleaning products that is known for, among other things, its various bike lubricants.
I’ve tested the company’s bike cleaners as well as their dry and wet chain lube for different riding conditions.
But now the company is apparently branching out into another industry that is slightly more, err…. intimate.
With the release of personal lubricant for adult activities, Muc-Off wants to be there for you no matter what you’re riding.
Though perhaps the company put it best, explaining that they “worked long and hard to develop a deep penetrating lubricant that fills that sweet spot between smoothness and abrasion. With our bicycle lubes the target is to hit zero friction, but following round, after round, after round of internal tests, we found friction to be vital in achieving a satisfactory outcome.“
Well there you go.
Charge your electric car with pedal power
If you thought traditional fast chargers were just too darn slow, then FastNed says they have the solution. And it just so happens to be connected to your feet.
The company is touting its new 750 kW fast charger known as Bike Boost that is powered by pedaling. They claim it can fill your electric car’s battery in just 5 minutes.
That’s more than just a Wheaties breakfast… that must require eating an entire truck of Wheaties!
Radio Flyer’s new air travel
We’ve been more attracted to Radio Flyer’s electric bikes lately, but perhaps it’s time to rethink travel by wheel. Instead, Radio Flyer has announced a new air service known as Radio FlyAir.
It’s not just a Radio Flyer jet though. The entire airline seems to have gotten the red wagon treatment, complete with wagon luggage carriers and kids riding through the terminal.
The best e-bike April Fools prank of all time?
Try as they might, I’m not sure any company will top what I believe to be the best April Fools product launch of all time: The RadFit from Rad Power Bikes.
Just as electric bikes have revolutionized the bike industry, so too can they upend the stationary exercise bike industry. At least that’s what Rad suggested with its electric stationary bike.
I don’t want to butcher this one, so just watch the short video below for the full effect. I promise that it’s worth it.

Scientists have found major storage capacity in water-based batteries
Texas A&M University scientists have been working with metal-free, water-based battery electrodes, and they’re finding that the difference in energy storage capacity is as much as 1,000%.
How the water-based batteries work
In the scientists’ paper, published in Nature Materials this week, the water-based, or aqueous, batteries consist of a cathode – the negatively charged electrode; an anode – the positively charged electrode; and an electrolyte, like traditional batteries. But in this water-based battery, the cathodes and anodes are polymers that can store energy, and the electrolyte is water mixed with organic salts.
The electrolyte transfers the ions – the charge-carrying particles – back and forth between the cathode and the anode, and the electrolyte is also key to energy storage through its interactions with the electrode.
Chemical engineering professor and co-author Dr. Jodie Lutkenhaus asserts:
If an electrode swells too much during cycling, then it can’t conduct electrons very well, and you lose all the performance.
I believe there is a 1,000% difference in energy storage capacity, depending on the electrolyte choice because of swelling effects.
According to their paper, the electrodes – the “redox-active non-conjugated radical polymers” – are promising candidates for water-based batteries because of the polymers’ high discharge voltage and fast redox kinetics.
However, the researchers note in their paper’s abstract:
[L]ittle is known regarding the energy storage mechanism of these polymers in an aqueous environment. The reaction itself is complex and difficult to resolve because of the simultaneous transfer of electrons, ions, and water molecules.
The future of aqueous batteries
The researchers suggest that water-based batteries might be able to mitigate potential shortages of metals such as cobalt and lithium, as well as eliminate the potential for battery fires.
There would be no battery fires anymore because it’s water-based.
In the future, if materials shortages are projected, the price of lithium-ion batteries will go way up. If we have this alternative battery, we can turn to this chemistry, where the supply is much more stable because we can manufacture them here in the United States and materials to make them are here.
The researchers also conducted computational simulation and analysis, and they’ll carry out further simulations to better understand the theory.
Chemistry assistant professor and co-author Dr. Daniel Tabor said:
With this new energy storage technology, this is a push forward to lithium-free batteries. We have a better molecular level picture of what makes some battery electrodes work better than others, and this gives us strong evidence of where to go forward in materials design.
