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.”
Despite the warnings, BYD continues introducing new discounts. On Wednesday, BYD’s luxury off-road brand began offering over 50% Huawei’s smart driving tech.
BYD introduces new discounts on smart driving tech
After BYD cut prices again in May, the China Automobile Manufacturers Association (CAMA) warned that the ultra-low prices are “triggering a new round of price war panic.”
Although they didn’t single out BYD, it was pretty obvious. BYD slashed prices across 22 of its vehicles by up to 34%, triggering several automakers to follow suit in China.
BYD’s cheapest EV, the Seagull, typically starts at about $10,000 (66,800 yuan). After the price cuts, the Seagull is listed at under $8,000 (55,800 yuan).
It doesn’t look like China’s EV leader plans to slow down anytime soon. Fang Cheng Bao, BYD’s luxury off-road brand, introduced new discounts on Huawei’s smart driving tech on Wednesday.
The limited-time offer cuts the price of Huawei’s Qiankun Intelligent Driving High-end Function Package to just 12,000 yuan ($1,700).
Buyers who order the smart driving tech in July will save over 50% compared to its typical price of 32,000 yuan ($4,500).
Earlier this year, Fang Chang Bao launched the Tai 3, its most affordable vehicle, starting at 139,800 yuan ($19,300). The Tai 3 is about the size of the Tesla Model Y, but costs about half as much.
The Tai 3 will spearhead a new sub-brand of electric SUVs following the more premium Bao 8 and Bao 5 hybrid SUVs.
BYD’s luxury off-road brand sold 18,903 vehicles last month, up 50% from May and 605% compared to last year. Fang Cheng Bao has now sold over 10,000 vehicles for three consecutive months.
The Chinese EV giant sold 382,585 vehicles in total in June, an increase of 12% from last year. In the first half of the year, BYD’s cumulative sales reached over 2.1 million, a YOY increase of 33%.

Every year, it seems like there’s a new headline about the world’s lightest electric bike. Each year, engineers manage to shave a few more grams off of an exotically designed frame built with even more exotic materials. And each year, the continuously lower weight is balanced by continuously higher prices – often exorbitantly high. But now Dahon has bucked that trend, offering us an incredibly lightweight electric bike at a price that normal e-bike riders can afford. Meet the Dahon K-Feather.
To put things in perspective, some of the previous lightest electric bicycles have included the 11.8 kg (26 lb) LeMond Prolog at US $4,500, the 11.75 kg (12.59 lb) Trek Domane+ SLR at US $8,999, and the 10 kg (22 lb) Hummingbird Flax folding e-bike at US $6,050.
So with that in mind, please allow me to introduce you to the new Dahon K-Feather. This is a 12 kg (26.5 kg) folding electric bike priced at an incredibly reasonable US $1,199 in North America or €1,499 in Europe.
Sure, it’s not the absolute lightest folding e-bike we’ve ever seen, but it’s 90% of the way there and at a quarter of the price. Plus, it comes from Dahon, which is one of the most respected names in the folding bike world and is largely credited with paving the way for the booming folding bike industry we see today. Since the 1980s, Dahon’s innovative designs have been imitated around the world, yet the folding bike maker has continued to innovate and stay several steps ahead of competing brands.
The K-feather achieves its extra low weight through the combination of a novel frame design employing Dahon’s patented frame designs, including the company’s DELTECH technology and “super down tube,” which help improve rigidity and robustness while reducing weight.
The electrical system on the K-Feather is also a featherweight, keeping the e-bike largely in the last-mile category. While the battery claims a maximum range of up to 24.8 miles (40 km), real-world riding and hilly terrain could reduce that range. Still, clever designs like a system that automatically shuts off the extra motor power when detecting a downhill segment help to eke out more range from the small 24V and 5Ah battery.
The ultra-lightweight 250W hub motor also offers just 32 Nm of torque, meaning the assist is more of a helpful push than a powerful shove. But with the inclusion of a torque sensor for the pedal assist, that push comes on quickly and reliably, making the bike feel more like a traditional analog bike being pedaled by someone with extra strong legs.
With 16″ dual-wall rims and 14g spokes, this isn’t the heavy fat tire folding e-bikes we’re used to in North America, and the capacity reflects that. The K-Feather is rated to support riders weighing up to 105 kg (231 lb), though the highly adjustable seating position can support a range of rider heights from 145 to 190.5 cm (4’9″ to 6’3″).
Coming in six colorways, the Dahon K-feather folding e-bike is now available in the US and has launched for pre-order in Europe, with shipments there expected in September.
I had a bit of a preview of the K-feather on my last trip to China when I was able to visit Dahon’s headquarters and test ride the bike.
I still can’t believe how light it felt, both underneath me and while folding it up and carrying it around. Be on the lookout for that full experience from my trip, coming soon.
Electrek’s Take
The K-Feather represents a compelling milestone not just for Dahon, but for the entire folding e-bike market. By delivering a truly lightweight, compact, and fully electric folder at an impressively affordable price point, Dahon has made minimalist e-mobility more accessible than ever.
It’s not just a bike for die-hard lightweight e-bike connoisseurs; it’s a real-world solution for commuters, travelers, and apartment dwellers who want the freedom of electric assist without the bulk or the sticker shock. If the goal is to get more people on two wheels, the K-Feather might just be one of the most important steps forward yet.
Coming in at less than half the weight of most folding e-bikes, and still a fraction of most lighter-duty folders, the K-Feather’s modest performance makes it a great urban ride for those who favor compact size and light weight. In fact, I think it might be perfect for my mother-in-law, who needs an e-bike to get to and from the train she takes to work, but also needs it to be light enough to carry up to her second-story apartment. Hmmm, perhaps I should have her do a review for us…

The Honda Prologue remains a top-selling EV in the US, but it’s Acura’s luxury electric SUV that’s been the surprise hit this year.
Honda Prologue sales rise while Acura’s EV surprises
After delivering the first Prologue models last year, Honda’s electric SUV quickly became a hit. In the second half of 2024, it was the second-best-selling electric SUV in the US, trailing only the Tesla Model Y.
Despite limited inventory due to the new 2025 model year change, Honda sold 2,799 Prologues last month. In the first half of the year, Honda has now sold 16,317 Prologue models in the US. In comparison, Toyota sold just over 9,200 units of its electric SUV, the bZ4X, during the same period.
Toyota’s luxury brand, Lexus, sold only 763 RZ models, its sole electric SUV, for a total of 3,779 units in the first half of the year.
Honda Prologue sales have now held steady, averaging over 2,700 units per month, but it’s Acura’s electric SUV that has been quietly gaining ground in the luxury EV space.
With another 1,318 models sold last month, Acura ZDX sales reached 10,355 in the first half of 2025. Acura’s electric SUV is even outpacing the Cadillac Lyriq, which is based on the same Ultium platform.
Sales are significantly higher than the company expected. Earlier this year, Mike Langel, vice president of national sales for Acura, told Automotive News that the company expected to sell around 1,000 ZDX models a month this year.
A significant reason behind the strong demand is the availability of massive discounts, which can reach nearly $30,000 in some states. The luxury electric SUV is more affordable than a Honda CR-V, with monthly leases starting at just $299.
The Honda Prologue is available to lease for as little as $259 per month. The offer is for 36 months with $2,399 due at signing in California and other ZEV states.
With the Trump administration planning to end the $7,500 federal EV tax credit, many of these savings will soon disappear.
If you’re looking to take advantage of the savings while they’re still available, we can help you get started. You can use our links below to find deals on the Honda Prologue and Acura ZDX in your area.
