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.”
![Here's our first official look at the new Hyundai EV debuting next month [Images]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/08/hyundai-ioniq-2-first-look.jpeg?resize=1200,628&quality=82&strip=all&ssl=1)
Is it the IONIQ 2 or 3? We are finally getting our first official look at the new Hyundai EV that will debut at next month’s Munich Motor Show. Take a look at the images below.
Hyundai offers a first look at its new EV
Rumors of a new entry-level Hyundai have been spreading like wildfire over the past few months. After a few prototypes have been spotted out in public testing, some claim it’s the IONIQ 2, while others say it will be called the IONIQ 2.
Either way, the new model is almost here, and it sounds like it could shake things up. Hyundai dropped the first official images of the new EV on Tuesday, offering a glimpse of what’s to come.
Although it’s just a teaser, the images reveal a few new design elements that will be showcased. The rear spoiler appears to be roughly the same shape and size as the updated IONIQ 6, which is likely to feature a full-length LED light bar.
The teaser comes after several test vehicles have been spotted recently, displaying a similar, upright, more SUV-like style reminiscent of the Kia EV2 concept.
Like its other IONIQ models and the Kia EV series, Hyundai’s new concept is likely to be based on its advanced E-GMP platform. It’s expected to fill the gap between the Inster EV and Kona Electric in Hyundai’s electric car lineup.
The interior is expected to be a step up from Hyundai’s current vehicles with a new infotainment system. Powered by its advanced new Pleos OS, the system will feel more like a smartphone.
Hyundai has yet to announce prices, range, and other final specs. However, since the Kona Electric starts at £34,995 ($47,000) in the UK, it will likely be priced closer to £25,000 ($33,700), like the Kia EV2.
Similar to the Kia EV3, Hyundai’s new electric car will likely be offered with 58.3 kWh and 81.4 kWh battery packs. The former provides a WLTP range of 260 miles, while the latter is rated with a range of 365 miles on a single charge.
The new Hyundai EV will make its global debut at the Munich Motor Show in Germany, from September 9 through September 14.
Kia’s EV3 is already the most popular retail electric vehicle in the UK through the first half of 2025. Will Hyundai match it with the new model?
Hyundai will reveal two new sets of images over the next week, so be sure to check back for the latest updates.

The Tesla Model Y has long been a dominant force in the EV world. It is the best-selling electric vehicle in the world, and it briefly became the best-selling car globally.
But it is being seriously challenged. In China, the Model Y is already feeling the impact of Xiaomi’s YU7.
Xiaomi wasn’t shy about positioning the YU7 against the Model Y when it unveiled the vehicle earlier this year.
The Chinese electronic giant turned EV manufacturer compared virtually every spec and price to Tesla’s best-selling EV, and it wasn’t surprising since the YU7 compares extremely favorably to Tesla’s refreshed Model Y.
The company announced that it aims to outsell the Model Y, and it made a strong start with more than 200,000 pre-orders within minutes of unveiling the vehicle.
The impact of the YU7 has already been felt throughout the Chinese EV market, as many buyers are expected to wait more than a year for the vehicle due to the backlog of orders, and Xiaomi still needs to ramp up production.
Lei Jun, Xiaomi’s CEO, is so unworried about demand that he even recommended people order from competitors due to the size of the YU7 backlog.
Despite being only two months into the start of YU7 deliveries, the vehicle appears to already be putting pressure on the Model Y.
New insurance data shows Model Y versus YU7 deliveries over the last 3 months (via ThinkerCar):
The sheer volume of YU7 pre-orders disrupted the entire small EV SUV market in China, but it has settled back after it became clear that someone placing a new order wouldn’t get the vehicle until next year.
Nonetheless, as deliveries ramped up to over 3,000 units per week over the last two weeks, Tesla’s deliveries are going down and they are still far off their highs.
It is increasingly looking like the YU7 will have a similar impact on the Model Y as Xiaomi’s SU7 had on the Model 3.
Over the last year, the SU7, Xiaomi’s first EV, has been consistently outselling the Model 3. Earlier this month, there was hope that Model 3 was making a comeback, but it looks like it is already back to normal:
Tesla’s sales are down 6% year-to-date in China based on registration data.
Electrek’s Take
China is the most interesting EV market because it is by far the most competitive one. That’s because Chinese automakers are not penalized there like they are in other markets.
Furthermore, Tesla can’t complain since it basically got the same deal as Chinese automakers with its Gigafactory Shanghai in the free trade zone.
For the last 5 years, the American automaker enjoyed some dominance in the Chinese market, but now local companies have caught up and Xiaomi is one of the best examples.
The impact of the SU7 on Model 3 is undeniable.
It’s still early to see the impact of the YU7, but it appears to be happening already. It is also cannibalizing SU7 sales.
If this trend continues, it appears that YU7 will outsell Model Y by the end of the year – although I would expect Tesla to start cutting prices before then, likely with the new stripped-down Model Y, which should delay YU7 becoming the sales leader into next year.

The Yangwang U9 is an EV powerhouse, packing four electric motors and a whopping 1,300 horsepower, but the new Track Edition model takes it to the next level. After reaching nearly 300 mph, BYD’s Yangwang U9 set a new global EV speed record.
BYD Yangwang U9 sets a new global EV speed record
BYD launched the U9 in February, its first electric supercar and the second vehicle under its ultra-luxury Yangwang brand.
The Yangwang U9 made an explosive debut, showcasing its dance moves, jumping capabilities, and sleek sports car design.
Earlier this month, we learned BYD was developing a new Yangwang U9 Track Edition model, packing a monstrous over 3,000 hp (2,20 kW). The standard U9 already features four advanced electric motors, providing a combined power of nearly 1,300 hp.
The souped-up variant has already set a global record, and it’s not even out yet. BYD announced on Tuesday that a Yangwang U9 Track Edition test vehicle broke the world EV speed record after reaching a ridiculous 472.41 km/h, or about 293 mph.
The achievement was certified at the ATP Automotive Testing Papenburg test track in Germany, beating the old EV speed record by over 20%.
BYD said that this “marks the first time a Chinese domestic brand has achieved a world record in this field.” Not only does it mark a massive leap forward for the Chinese auto industry, but it also marks a significant milestone for electric vehicles as a whole.
The Yangwang U9 starts at 1,680,000 yuan in China, or about $233,000. That’s around half the cost of a new Ferrari SF90 Stradale or Lamborghini Aventador SVJ.
BYD’s Yangwang U9 is faster and even more affordable than most internal combustion engine (ICE) supercars. And the interior features “the smartest supercar cockpit,” BYD claims, powered by its advanced DiLink infotainment system. Which one are you taking?
You can see how fast BYD’s electric supercar really goes in its record-setting run in the video above. We should learn more about the new Yangwang U9 Track Edition model soon. Check back for the latest.
