Range and recharge times are perhaps the two biggest issues currently facing electric vehicles. But StoreDot is ready to solve at least one of those. The company just showed off its fast charging batteries by topping up an empty electric scooter battery in just 5 minutes.
Electric scooters have taken the world by storm over the last few years. Cities like Paris have as many as 20,000 electric kick scooters on their streets. And they all run out of charge faster than riders would like.
So wouldn’t it be nice if they could be recharged in minutes instead of hours?
StoreDot’s new scooter batteries now prove that 5-minute recharges aren’t a dream anymore. During the Israeli battery company’s demo, a Torrot Muvi electric scooter with a completely discharged battery was topped up to 100% in just 5 minutes. That bought the scooter another 70 km (43 mi) of range.
“This is showing the world that we can break the barrier of fast charging, and what was considered impossible is actually possible,” said StoreDot Chief Executive Officer Doron Myersdorf, according to Bloomberg.
But don’t take a screwdriver to your scooter in hopes of a battery swap just yet. StoreDot’s scooter batteries won’t be ready for retail sales until 2021. In the meantime, StoreDot is working on developing fast charging batteries for a number of different products, from 5-minute cell phone charging to full-size electric cars.
The company’s next proof of concept will be for a Mercedes electric vehicle. StoreDot plans to pump 480 km (300 mi) of range into the Mercedes in just 5 minutes, just like the electric scooter battery.

StoreDot’s batteries, while still part of the larger class of Li-ion batteries, contain less lithium but more germanium and tin than other Li-ion batteries. StoreDot also includes anti-degradation agents into the battery chemistry to combat the biggest downside of fast battery charging: faster wear rates of batteries.
How much will StoreDot’s batteries cost once they make it out of the lab and onto the market? That’s anyone’s guess, but they certainly won’t be cheap in the beginning. As Doron explained, “Try to put a price tag on something that didn’t exist before. The sky is the limit in terms of value that impacts each person on the planet, and the planet itself.”
Pretty exciting stuff, though I’m waiting to see how commercializing this tech will go. With good quality electric scooters currently costing just $400 on Amazon, I’m not sure I’ll want to pay four figures for a scooter just to make it charge quicker. And I can’t even imagine how much a full-size electric vehicle battery will cost.
But as with all new technology, the price is often sky high in the beginning before it floats down for the rest of us commoners.
Perhaps what I’m most excited about is seeing 5-minute charging in electric motorcycles. So far, electric motorcycles can do just about everything gas bikes can do. The one area where they still fall short is range. Without any big advances in battery energy density on the horizon, fast charging is the next best thing. If I could get an electric motorcycle with 150 mile (240 km) range and 5-minute charge time, I’d be pleased as punch. Electric motorcycle touring would finally be a thing.
Let’s do this, StoreDot!

Gen X and Y just got their Beatles Anthology, basically – and it’s fantastic. Radiohead remind us why we love them with nearly two gigs of demos ripped from (seriously) MiniDiscs.
Maybe it’s taking Radiohead back to the “just a band” phase, but there’s something gorgeous about these stripped-down and earnest productions. And if you don’t want to burden yourself with the 1.8GB, you can stream them to get a rough impression of one of the biggest bands of their generation when … they were developing ideas and didn’t bother to tune their guitars.
Live sets in there, too, sketches, the lot…
The amazing thing about this story is, they evidently are kidding about being “hacked” – it seems someone really did try to ransom all these all recordings. (Maybe. It’s certainly a believable possibility.)

Of course, unlike the previous generation’s demos, the 90s produced recordings that were pretty half-decent. You’ll hear some charming sounds as mics are moved about, but the quality is pretty crisp – and then you get an in-the-room quality missing in the umpteen times we’ve heard Radiohead’s albums and then various covers.
Heck, even though I run a site that celebrates technology, you might just say the band is even a bit better in this raw, punk format, without all the studio work. There’s just way too much to listen to all at once, but £18 GBP gets you what in the 90s we thought was a big file (two gigs is a lot of dialup download time).
Someone could say something about the value of music here, except Radiohead already have given away albums, so really, this is a slight increase of value? I guess?
Enjoy. And maybe dust off your MiniDisc recorder and go make something.

Suede is a leather material used to make belts, watch straps, bags, and more. Men are most likely to encounter it in shoes, like chukka boots. Suede looks and feels good; it adds a unique visual and physical texture to your footwear and accessories.
But for a lot of guys, suede can seem like an intimidating material. You’ve perhaps heard about its delicate nature — that it is easily scratched and scuffed and can be readily damaged by water, grease, and other elements and stains.
While suede isn’t quite as sensitive as it’s been made out to be, it does have its own care routine that differs from other leathers. We’ll get into that in just a bit. But first let’s have a look at what suede is and how it’s made. With both bits of knowledge under your (suede) belt, you’ll be well on your way to eliminating your aversion to this handsome material.
What Is Suede?
If you’re anything like me, it’s possible that the way suede is labeled and marketed has made you think that it’s an entirely different variety of leather (or material altogether!) — something man-made or exotic.
The reality is much simpler: leather is a material made from the hide of any number of animals (cow, sheep, crocodile, etc.), and suede is formed through a process that can be applied to any of those leathers.
Manufacturing leather is a complex process, and different parts of the hide go into making the different kinds of leather — full grain, top grain, bonded, etc. Suede is the softer underside of the hide. Sometimes manufacturers will just flip the hide over, but that creates a stiff material that isn’t generally what you’re going for with suede (though Red Wing does this and calls it “Roughout” leather). Most of the time suede is actually made from a thin middle layer that gets fully cut away from the outer part of the hide. Suede is thinner, more naturally porous (hence being known as a water-sensitive material), and, since it was undercover and protected from the elements when it was part of the animal, not as naturally toughened up as the types of leather taken from the outside of the hide. The result is a napped material that’s softer, lighter, and, more prone to damage.
It should be noted that most suede is made from lamb — while other hides can be used, lamb suits itself best to the process; larger animals create a much shaggier nap, which just doesn’t look as nice.
What About Nubuck?
If you’ve ever shopped around for suede you’ve likely also encountered the term “nubuck” or “nubuck suede.” Rather than coming from an inner layer of the hide, nubuck is actually full grain leather that’s been sanded/buffed to give it a slight nap. So it looks and feels much like suede, but with two main differences: 1) it’s not quite as soft, and 2) it’s a bit more heavy and durable since it’s the outer part of the hide. This also means it doesn’t quite need the same maintenance (though the below routine can still be followed, just less frequently). When it comes to nubuck vs. true suede it’s not really a question of one of them being better or worse; it’s more about what you’re looking for in the material.
How to Care for Suede and Make It Last
As previously alluded to, suede isn’t as delicate as you may think. Scratches can be buffed away, and a little bit of water or dirt isn’t going to permanently ruin your shoes.
But, it does need to be cared for and maintained, just as your other leathers do, albeit with a different process and set of products. The bristles in the brush in your standard leather care kit are usually a bit large to be working on suede, and you definitely don’t want to be using any polish/cream on the material, nor a wet cloth.
So first, get yourself a suede care kit. Any suede-specific kit will come with a small brush (and sometimes a second brush specifically for maintaining the nap) as well as what’s called a suede eraser (or sometimes suede block). It’s basically a large rubber eraser that removes scuffs. And depending on the kit, you may also get a leather protector in the form of a clear spray.
As soon as you crack open your new suede shoes or belt, give it a spray with the protectant.
From there, use the following routine — once a month or so for irregular use; every 1-2 weeks with regular all-day wear — to regularly care for your suede and make sure that it lasts for years to come:
Use the bristle brush to clean off any dirt, sediment, etc. Don’t press too hard and scuff the material — it’s more like the pressure of brushing your teeth than washing dishes. You also want to brush in a single direction to keep the nap uniform.
When you brush, it does appear to change the color some, but that’s just the nap fluctuating (just like what happens when you run your hand over a suede or velvety couch).
If there are specific spots or any stains on the material that didn’t come out with the first brushing, use the eraser to gently scrub them off. Again, use a light pressure. The eraser works great for nearly any stain that isn’t grease (more on that below) as well as scuffs and small scratches.
One thing that can truly muck up any material — suede included — is grease. One little spot can really ruin the uniform look of a shoe or accessory. With this particular type of stain, there’s one product that does near-miraculous wonders: cornstarch.
Apply a small pile to the stain (be liberal here), allow at least 15 minutes for the cornstarch to sit and absorb the grease (up to an hour or so), and then brush away with your suede brush. One application may very well remove the stain completely. If not, apply cornstarch again and repeat the process until the stain is gone. Give the area a scrub with the eraser, then give it a final brush to fully remove any residue and restore the nap.
Don’t try to use other grease-fighting agents, like dish soap, as they can ruin the material.
Bonus #1: cornstarch can also be used effectively even on old and seemingly set-in stains (though it’s not a guarantee of course).
Bonus #2: cornstarch can be used on any material to remove grease. No more relegating stained shirts to the rag pile.
3. Brush Again
After you’ve used your eraser, brush the suede once again, in a uniform direction. If your kit comes with a second brush (often called a “crepe” brush), use it here.
Apply a clear protectant by holding the item about arm’s length away and giving it a good spray all over. The material will probably change color some, but don’t worry at all, that will go away.
If your suede gets wet, don’t fret. If it’s just a little bit, let it dry, then give it a brushing. If it got quite wet or muddy, dab it dry with a paper towel, let it dry, and give it a clean. If you’ve been regularly applying the spray, you don’t have much to worry about.
If you do end up with a stain of any kind that you can’t get out yourself with either a brush or eraser (or cornstarch), look for a dry cleaner in your area that does leather/suede.
Again, while suede is not a delicate fabric per se, it is more prone to damage. So you might as well not take chances with how you wear it. In general, do yourself a favor and just don’t put on the suede boots if the forecast calls for inclement weather, or if your agenda calls for a muddy adventure.
If you do that, and follow the maintenance routine described above, your suede products will find years of enjoyable use.
