How a Jack Dorsey-backed bitcoin miner uses a volcano in Kenya to turn on the lights in rural homes
HELL’S GATE, Kenya — Two-and-a-half hours northwest of Nairobi by car, a small group of bitcoin miners set up shop at the site of an extinct volcano near Hell’s Gate National Park.
The mine, tucked away on the edge of Lake Naivasha, is operated by a startup called Gridless and consists of a single 500-kilowatt mobile container that, from the outside, looks like a small residential trailer.
Backed by Jack Dorsey’s Block, Gridless electrifies its machines with a mix of solar power and the stranded, wasted energy from a nearby geothermal site. It’s one of six mines run by the company in Kenya, Malawi and Zambia, powered by a mix of renewable inputs and working toward a broader mission of securing and decentralizing the bitcoin network.

“Most people think about bitcoin and the price of bitcoin and how they can save value in it or maybe spend it,” Gridless CEO Erik Hersman told CNBC during a visit to the Kenyan mine earlier this year. “That doesn’t happen without the bitcoin miners and us being globally distributed.”
Decentralization is a key feature of bitcoin, because it means the network isn’t controlled by any entity and can’t be shut down — even if a government disapproves.
Bitcoin and some other cryptocurrencies are created through a process known as proof-of-work, in which miners around the world run high-powered computers that collectively validate transactions and simultaneously create new tokens. The process requires heaps of electricity, leading miners to seek out the cheapest sources of power.
While there are more than a dozen publicly traded miners, thousands of smaller, private operations are also competing to process transactions and get paid in new bitcoin. That includes individual miners in countries from Venezuela to Lebanon, and can involve a single mining rig in a kitchen or several hundred thousand of them in an industrial-grade datacenter.

Wherever the operation, bitcoin mining is a volatile business, because so much of the economics depends on the price of the cryptocurrency. Since losing 60% of its value in 2022, bitcoin has come roaring back, hitting a record above $73,000 in March, before pulling back a bit in recent weeks.
Much of the rally has been tied to the launch of spot bitcoin exchange-traded funds in the U.S., as well as optimism surrounding the so-called halving that took place late Friday. That event occurs every four years and is designed to cut the reward for bitcoin miners in half, reducing the pace at which new bitcoins enter the market. Prior halving events have been followed by big run-ups in the cryptocurrency.
“Bitcoin is effectively unbreakable at this point,” said Adam Sullivan, CEO of Core Scientific, a bitcoin miner based in Texas. “Bitcoin is at a point where it is more profitable to continue supporting the network than to try and break it.”
Analysts at Deutsche Bank wrote in a note on April 18 that they expect the geography of crypto mining to shift after the halving as slimmer profit margins force miners to seek cheaper and more reliable forms of energy. The analysts wrote that the U.S. currently accounts for 40% of mining, with Russia at 20% and China at 15%.
“Latin America, Africa and the Middle East have caught the attention of crypto miners due to their lower energy costs,” they wrote.
Bitfarms, based in Toronto, is now operating in Argentina, while Marathon Digital, headquartered in Florida, has expanded into the United Arab Emirates and Paraguay.
Hersman, 48, was raised in Kenya and Sudan, where his parents were linguists. Before getting into bitcoin mining, he and his two co-founders, Philip Walton and Janet Maingi, spent years building internet connectivity infrastructure in rural and urban Africa.

In early 2022, the trio began brainstorming creative solutions for the divide between power generation and capacity, and the lack of access to electricity in Africa. They landed on the idea of bitcoin mining, which could potentially solve a big problem for renewable energy developers by taking their stranded power and spreading it to other parts of the continent. In Africa, 43% of the population, or roughly 600 million people, lack access to electricity.
Gridless now has eight full-time staffers and manages much of its operations remotely with its software.
Turning lava into bitcoin
Hell’s Gate is a deep and winding canyon that is home to cheetahs, zebras, and giraffes and rimmed by cliffs, volcanoes and thick bush.
The area is covered in ash, and sulfuric plumes of steam will periodically emit from the ground, a reminder of the surrounding, smoldering volcanic craters that wiped out some of the native Maasai tribe in the mid-19th century and threatened others who dared to take up residence there.
Gone are the days of fatal eruptions and spewing lava. Instead, an elaborate, labyrinthine piping system and volcanic plugs comprise multiple geothermal power stations.

Volcano-powered bitcoin mining isn’t new.
Iceland, El Salvador and other countries have been harnessing geothermal energy to mine bitcoin. To make the conditions work for miners, the businesses need the combination of a buy-in from local authorities, cheap and abundant power and some infrastructure, said Nic Carter, founding partner of Castle Island Ventures, which focuses on blockchain investments.
“If you have those three ingredients, it can work, but sometimes, it’s the nation state, or a national, state energy company doing it,” Carter said. He pointed to the Middle East, which is getting into flare gas mining as an example of state-level actors entering the business.
“In some cases, it’s with the explicit blessing of the nation state like Bhutan, and then in Texas, it’s just with very favorable local regulators and local conditions,” he said.
Africa is home to an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro and another 110 gigawatts of wind.
Some of this renewable energy is being harnessed already, but a lot isn’t because building the specialized infrastructure to capture it is expensive. Even with 60% of the best solar resources globally, Africa only has 1% of installed solar PV capacity.
Enter bitcoin miners.
Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help unlock these trapped renewable sources of power. Miners are essentially energy buyers, and co-locating with renewables creates a financial incentive to bolster production.
“As often happens, you’ll have an overage of power during the day or even at night, and there’s nobody to soak that power up,” said Hersman. He said his company’s 50-kilowatt mining container can “take up whatever is extra throughout the day.”

“Within any second or minute, we are going up and down on a certain number of miners that are running,” Hersman said. “It might be down to 50 kilowatts, then up to 300 kilowatts, then down to 200 kilowatts, and then up to another level — and that will happen all day and all night.”
According to the International Energy Agency, in Africa’s rural areas, “where over 80% of the electricity-deprived live, mini-grids and stand-alone systems, mostly solar based, are the most viable solutions.”
Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable. The power supplier benefits from selling energy that previously had been discarded, while the energy plants will sometimes lower costs for the customer. At one of the Gridless pilot sites in Kenya, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents per kWh.
The buildout of capacity is also electrifying households.
Gridless says its sites have powered 1,200 houses in Zambia, 1,800 in Malawi and 5,000 in Kenya. The company’s mines also have delivered power for containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.
“It’s not really sexy,” Hersman said. “It’s a mining container made from a shipping container. It’s got a bunch of dumb machines sitting in it running the same equation over and over again, but it’s actually what secures the network.”
BMW Motorrad’s futuristic electric scooter just got its first real refresh since beginning production in 2021. The BMW CE 04, already one of the most capable and stylish electric maxi-scooters on the market, now gets a set of upgraded trim options, new aesthetic touches, and a more robust list of features that aim to make this urban commuter even more appealing to riders looking for serious electric performance on two wheels.
The BMW CE 04 has always stood out for its sci-fi styling and high-performance drivetrain. It’s built on a mid-mounted liquid-cooled motor that puts out 31 kW (42 hp) and 62 Nm of torque. That’s enough to rocket the scooter from 0 to 50 km/h (31 mph) in just 2.6 seconds – quite fast for anything with a step-through frame.
The top speed is electronically limited to 120 km/h (75 mph), making it perfectly capable for city riding and fast enough to hold its own on highway stretches. Range is rated at 130 km (81 miles) on the WMTC cycle, thanks to the 8.9 kWh battery pack tucked low in the frame.
But while the core performance hasn’t changed, BMW’s 2025 update focuses on refining the package and giving riders more options to tailor the scooter to their taste. The new CE 04 is available in three trims: Basic, Avantgarde, and Exclusive.
The Basic trim keeps things clean and classic with a Lightwhite paint scheme and a clear windshield. It’s subtle, sleek, and very much in line with the CE 04’s clean-lined aesthetic. The Avantgarde model adds a splash of color with a Gravity Blue main body and bright São Paulo Yellow accents, along with a dark windshield and a laser-engraved rim. The top-shelf Exclusive trim is where things get fancy, with a premium Spacesilver metallic paint job, upgraded wind protection, heated grips, a luxury embroidered seat, and its own unique engraved rim treatment.
There are also a few new tech upgrades baked into the options list. Riders can now spec a 6.9 kW quick charger that reduces the 0–80% charge time to just 45 minutes (down from nearly 4 hours with the standard 2.3 kW onboard charger). Tire pressure monitoring, a center stand, and BMW’s “Headlight Pro” adaptive lighting system are also available as add-ons, along with an emergency eCall system and Dynamic Traction Control.
BMW has kept the core riding components in place: a steel-tube chassis, 15-inch wheels, Bosch ABS (with optional ABS Pro), and the impressive 10.25” TFT display with integrated navigation and smartphone connectivity. The under-seat storage still swallows a full-face helmet, and the long, low frame design means the scooter looks like something out of Blade Runner but rides like a luxury commuter.
With these updates, BMW seems to be further cementing the CE 04’s role at the high end of the electric scooter market. It’s not cheap, starting around €12,000 in Europe and around US $12,500 in the US, with prices going up from there depending on configuration. However, the maxi-scooter delivers real motorcycle-grade performance in a package that’s easier to live with for daily riders.
Electrek’s Take
I believe that the CE 04’s biggest strength has always been that it’s not trying to be a toy or a gimmick. It’s a real vehicle. Sure, it’s futuristic and funky looking, but it delivers on its promises. And in a market that’s still surprisingly sparse when it comes to premium electric scooters, BMW has had the lane mostly to itself. That may not last forever, though. LiveWire, Harley-Davidson’s electric spin-off brand, has teased plans for a maxi-scooter-style urban electric vehicle in the coming years, but as of now, it remains something of an undefined future plan.
Meanwhile, BMW is delivering not just a concept bike but a mature, well-equipped, and ready-to-ride electric scooter that keeps improving. For riders who want something faster and more capable than a Class 3 e-bike but aren’t ready to jump to a full-size electric motorcycle, the CE 04 hits a sweet spot. It delivers the performance and capability of a commuter e-motorcycle, yet with the approachability of a scooter. And with these new trims and upgrades, it’s doing it with even more style.

If you’ve ever wondered what happens when you combine a fruit cart, a cargo bike, and a Piaggio Ape all in one vehicle, now you’ve got your answer. I submit, for your approval, this week’s feature for the Awesomely Weird Alibaba Electric Vehicle of the Week column – and it’s a beautiful doozie.
Feast your eyes on this salad slinging, coleslaw cruising, tuber taxiing produce chariot!
I think this electric vegetable trike might finally scratch the itch long felt by many of my readers. It seems every time I cover an electric trike, even the really cool ones, I always get commenters poo-poo-ing it for having two wheels in the rear instead of two wheels in the front. Well, here you go, folks!
Designed with two front wheels for maximum stability, this trike keeps your cucumbers in check through every corner. Because trust me, you don’t want to hit a pothole and suddenly be juggling peaches like you’re in Cirque du Soleil: Farmers Market Edition.
To avoid the extra cost of designing a linked steering system for a pair of front wheels, the engineers who brought this salad shuttle to life simply side-stepped that complexity altogether by steering the entire fixed front end. I’ve got articulating electric tractors that steer like this, and so if it works for a several-ton work machine, it should work for a couple hundred pounds of cargo bike.
Featuring a giant cargo bed up front with four cascading fruit baskets set up for roadside sales, this cargo bike is something of a blank slate. Sure, you could monetize grandma’s vegetable garden, or you could fill it with your own ideas and concoctions. Our exceedingly talented graphics wizard sees it as the perfect coffee and pastry e-bike for my new startup, The Handlebarista, and I’m not one to argue. Basically, the sky is the limit with a blank slate bike like this!
Sure, the quality doesn’t quite match something like a fancy Tern cargo bike. The rim brakes aren’t exactly confidence-inspiring, but at least there are three of them. And if they should all give out, or just not quite slow you down enough to avoid that quickly approaching brick wall, then at least you’ve got a couple hundred pounds of tomatoes as a tasty crumple zone.
The electrical system does seem a bit underpowered. With a 36V battery and a 250W motor, I don’t know if one-third of a horsepower is enough to haul a full load to the local farmer’s market. But I guess if the weight is a bit much for the little motor, you could always do some snacking along the way. On the other hand, all the pictures seem to show a non-electric version. So if this cart is presumably mobile on pedal power alone, then that extra motor assist, however small, is going to feel like a very welcome guest.
The $950 price is presumably for the electric version, since that’s what’s in the title of the listing, though I wouldn’t get too excited just yet. I’ve bought a LOT of stuff on Alibaba, including many electric vehicles, and the too-good-to-be-true price is always exactly that. In my experience, you can multiply the Alibaba price by 3-4x to get the actual landed price for things like these. Even so, $3,000-$4,000 wouldn’t be a terrible price, considering a lot of electric trikes stateside already cost that much and don’t even come with a quad-set of vegetable baskets on board!
I should also put my normal caveat in here about not actually buying one of these. Please, please don’t try to buy one of these awesome cargo e-trikes. This is a silly, tongue-in-cheek weekend column where I scour the ever-entertaining underbelly of China’s massive e-commerce site Alibaba in search of fun, quirky, and just plain awesomely weird electric vehicles. While I’ve successfully bought several fun things on the platform, I’ve also gotten scammed more than once, so this is not for the timid or the tight-budgeted among us.
That isn’t to say that some of my more stubborn readers haven’t followed in my footsteps before, ignoring my advice and setting out on their own wild journey. But please don’t be the one who risks it all and gets nothing in return. Don’t say I didn’t warn you; this is the warning.
