Jack Dorsey’s Block backs bitcoin mining company that wants to bring 25-cent electricity to rural Africa

ACCRA, GHANA — Up until February, Janet Maingi didn’t think much about bitcoin. Born and raised in the Kenyan capital of Nairobi, Maingi had instead spent more than twenty years focused on trying to solve one of Africa’s biggest problems: connectivity. To that end, she spent more than 20 years working in operations in the telecom industry, in companies specializing in internet and wireless networks to cable and satellite television. But earlier this year, the 45-year-old mother decided to take on the continent’s second-biggest issue: Its energy problem.
Africa is a renewable energy mecca. There’s an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro, and another 110 gigawatts of wind, according to data from Energy, Capital & Power, an investment platform focused on Africa’s energy sector.
Some of this renewable energy is being harnessed already, but a lot of it isn’t, because it is expensive to build the kind of specialized infrastructure necessary to capture it. Even though Africa boasts 60% of the best solar resources globally, the continent only has 1% installed solar PV capacity, according to the International Energy Agency.
“When you sit back and look at rural Africa and rural Kenya, one of the things that is very prevalent in the homes — I am talking about the 50% that are not electrified — is children have to do their assignments using either paraffin lamps or candles,” Maingi told CNBC on the sidelines of the Africa Bitcoin Conference in Accra.
“Think of their eyesight, think of their health,” she said.

Maingi was frustrated by the divide between generation and capacity, given that 43% of Africa’s population, or 600 million people, lack access to electricity. So in February, she began spitballing creative solutions with two friends, and the three of them landed on a sort-of counterintuitive idea: bitcoin mining.
Mining for the world’s biggest cryptocurrency is a process known as proof-of-work. Miners around the world run high-powered computers that collectively validate transactions and simultaneously create new tokens. The process requires a lot of electricity, and because this is the only variable cost in a low-margin industry, miners tend to seek out the world’s lowest-cost sources of power.

Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help to unlock these trapped renewable sources of energy. Bitcoin miners are essentially energy buyers, and when they co-locate with renewables, it creates a financial incentive for buildout and improves the core economics of renewable power production. The IEA says that in rural areas “where over 80% of the electricity-deprived live, mini-grids and stand-alone systems, mostly solar based, are the most viable solutions.”
By May, Maingi and her two colleagues decided to try it out. They founded a venture called Gridless to see whether the additional demand of bitcoin miners on these semi-stranded assets could make renewables in Africa economically viable — and crucially, whether the additional source of energy could power communities previously out of reach of microgrids that electrify parts of Africa.
Gridless also has plans to expand into other parts of Africa with the help of a fresh injection of cash.
Jack Dorsey’s digital payments firm Block and Alyse Killeen’s bitcoin-focused venture firm Stillmark, have led a $2 million seed investment into the company, which Gridless says it plans to use to open new mines.
Maingi is the chief operations officer, and her two friends turned co-founders, chief executive Erik Hersman, and chief financial officer Philip Walton, have spent the last several months launching pilots across Kenya in which they work with mini-grid hydro and solar generators to use their excess capacity to mine.
“We had spent years building internet connectivity infrastructure in rural and urban Africa, and realized that you cannot have a 21st-century economy without both power and connectivity together,” Hersman told CNBC.

“As we looked at the next problem to solve, we realized that bitcoin mining solved a major problem for renewable mini grid energy developers, in that we could be their industrial off-taker for stranded power, no matter where they were located, thereby making them more sustainable and increasing electrification across Africa,” continued Hersman.
Gridless currently has three operational pilot sites in Murang’a, a rural town that’s a 90-minute drive northeast of Nairobi. Each mine runs on hydroelectric power from HydroBox, an energy company based on the continent. Two of the mines have about 50 kilowatts of capacity, and by Thursday, the third mine will expand to 300 kilowatts.
To put those numbers into perspective, 30 kilowatts would power about 500 households. 50 kilowatts is closer to 800 households.
In January, Gridless plans to launch another 50-kilowatt hydromine in Malawi and its first solar-powered site in West Africa that will have a 30 kilowatt capacity.
Lowering energy costs
So far, the economics make a lot of sense for everyone involved. Gridless serves as a sort of anchor tenant. The company finances construction and manages the operation of data centers in rural communities where traditional industrial or commercial customers are not available, according to a company statement released Tuesday.

Because the power supplier benefits from selling energy that previously had been discarded, the energy plants will sometimes lower costs for the end user. At one of their pilot sites in Kenya, for example, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents.
The buildout of capacity is also electrifying households. Gridless says they’ve already seen this translate to containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.
Once those types of needs are met, Gridless said in a statement that the remaining electricity capacity is used to power the bitcoin mine.
“Bitcoin and mining is really the tool. We’re not doing bitcoin for bitcoin,” said the lead for bitcoin mining and wallet at Block, Thomas Templeton. “The whole objective is really to empower these villages. Bitcoin is a means to that end.”
Block previously announced in April it would be teaming up with Blockstream to break ground on a solar- and battery-powered bitcoin mine in Texas that uses solar and storage technology from Tesla.
Block is also working on a project to make bitcoin mining more distributed and efficient.
Making the mining process more accessible has to do with more than just creating new bitcoin, according to Templeton. Instead, he says the company sees it as a long-term need for a future that is fully decentralized and permissionless.
The company is solving one major barrier to entry: Mining rigs are hard to find, expensive and delivery can be unpredictable. Block says it is looking into making a new ASIC, which is the specialized gear used to mine bitcoin.
Democratizing access to the mining process is big for Block. Right now, Africa accounts for around 0.2% of the global bitcoin hashrate (an industry term used to describe the collective computing power of the entire network), according to the Cambridge Centre for Alternative Finance. The bulk sum of the hashpower shifted from China to the U.S. over the last 18 months after Beijing banned crypto mining. Many in the industry tell CNBC that this kind of centralization is a problem.
“Decentralized mining is essential for the resiliency of bitcoin,” said Templeton, who added that Block kicked off its mining initiative to make mining more accessible, user-friendly and reliable, so that more people can mine.
It was a sentiment echoed by Dorsey in Accra on Tuesday morning. The Block CEO, who said he still plans to move to Africa for six months, added that Block wants to partner with other companies on the continent to make it easier to onboard people into bitcoin.
“We’re working on a hardware miner to make it more, hopefully, accessible and more efficient for people around the world and especially on the continent to participate in securing the network and making it even more resilient in the form of something that’s also useful for other things, not just mining.”
Supporting the rise of bitcoin mining across Africa also translates to another big goal for Block: Helping to accelerate global renewable hashrate.
“Gridless represents a close strategic alignment with our vision of ensuring the bitcoin network increasingly leverages clean energy, in combination with bitcoin computational centers around the world,” said Templeton.
Yolo County, California depends on its climate for continued agricultural success. As such, the county’s leaders are taking environmental stewardship seriously by aiming for full carbon neutrality by 2030. To help achieve that goal, they’re putting zero-emission machinery like the Volvo DD25 Electric compactor to work.
We got our first chance to sample the DD25 Electric at Volvo Days last summer, where the all-electric tandem roller’s vibrating drums impressed dealers and end users alike. It was no surprise, then, that when Yolo Country fleet superintendent, Ben Lee, when shopping for a compactor the DD25 Electric was high on his list.
“The DD25 Electric will help us achieve our goals in several ways,” explains Lee. “By reducing emissions, lowering noise levels, being more energy-efficient, improving working conditions and promoting environmentally friendly practices … we’ll use it to compact soil, gravel and other base materials for road and foundation projects, as well as rolling out and leveling asphalt during road construction and resurfacing.”
To help Lee handle those various projects, the Volvo’s drum frequency can be adjusted from 3500 vpm (55 Hz) to 4000 vpm (67 Hz) to cater to different applications and materials.
The DD25 Electric offers other benefits, as well – like a 20 kWh 48V battery that offers up between six and eight hours of continuous operation. That’s could be several shifts in the kind of conditions Yolo’s work crews will encounter, meaning it will only have to get put to bed (Volvo recommend overnight AC charging) two or three times a week.
Getting power to the compactor, too, is something Yolo is considering. “There are some remote areas in the county, so we’re looking into a mobile, self-contained charging unit as well,” explains Lee, apparently referencing the Volvo PU130 mobile battery. “So we wouldn’t have to bring the machine back to the yard each night during a long-term project.”
Yolo County views electric equipment as an essential step in reducing emissions and energy consumption, especially as communities work towards stricter regulations and sustainability goals.
Electrek’s Take
This press release came to us ahead of the devastating wild fires in Southern California that are dominating headlines right now – so much so that I effectively sat on the news for a few days, debating whether or not we should even be talking about a California news story that isn’t about the fires right now.
But I realized: this story is about the fires. Climate change driven by combustion and carbon emissions is driving climate change and that’s making fires like these possible … and I should have run it sooner.

Kubota came to this year’s CES with a sprawling display filled with electric equipment, hydrogen gensets, and an onslaught of commercial robots ready to mow, farm, dig, and build. If you weren’t impressed by Kubota’s display this year, you weren’t paying attention.
Kubota gave us a sneak peek of its KATR farm robot – itself a smaller, updated version of last year’s New Agri Concept – before the doors officially opened last week. Kubota’s robotic farm buddies promise to be able to quietly and autonomously haul stuff from one end of the farm to another, or pull carts and specialized implements along predetermined paths.
KATR uses self-leveling technology and active suspension to ensure its cargo deck stays level when working on the sort of uneven terrain found on farms or construction sites.
That doesn’t mean the New Agri Concept is dead, though. Agri Concept 2.0 debuted as an electric tractor concept offering AI-powered automation and a fully electric powertrain. The new version features a Lite Brite-style “grille” that it uses to communicate its current mode, direction, and other important information with the people it shares a job site with.
On the more practical side, Kubota showed off its KX38-4e Electric compact excavator. First shown in overseas markets in 2022, the KX38-4e Electric features a 49.2 kWh lithium-ion battery that’s good for up to five hours of continuous operation. More than enough to complete a typical day of work on a construction site when you factor out idle time.
An onboard DC fast charger means it can be quickly recharged between shifts, too. But when there’s no grid power on the site, charging can be a challenge. That’s why Kubota has hydrogen genset for zero-emission on-site power generation.
Looked at individually, each of the new electric Kubota products on display might be impressive. The real magic, though, is in the way the Kubota machines work together as a holistic job site or farm solution.
“At Kubota, we believe that truly listening to our customers drives innovation in every aspect of what we call the ‘Work Loop’,” explains Brett McMickell, Chief Technology Officer of Kubota North America. “The Work Loop — an essential cycle of assessing, analyzing, and acting — has always been fundamental to effective task management. With the integration of advanced sensors, AI-driven analysis, networking protocols, automation, and robotics, we are enhancing this cycle to be more seamless and efficient than ever before.”
That was obvious in some of the more thoughtful implements and attachments on display, including a Smart Plant Imager that uses advanced robotics and “hyper-spectral imaging” cameras to capture real-time data and insights on a plant-by-plant level – as well as a Smart Autonomous Sprayer and Robotic Pruner that that classifies buds and canes based on position and fruiting potential, it optimizes production precision and accuracy.
The more you look, the more impressive Kubota’s farming solution gets. “We will continue to learn from many of our customers across segments to iterate the next product and technology solution that will help them manage tomorrow’s challenges and grow their businesses,” McMickell added. “This is how Kubota works to make a better quality of life for individuals and society.”
There was more, of course. Autonomous versions of the company’s electric zero-turn mower with GPS-powered route memory, fun accessory baskets for the robots, even a weird, jet engine looking thing that I forgot to ask about (below). I was genuinely impressed, in other words, and can’t wait to see what Kubota comes up with next year.

The e-bike industry has stalled a little bit in terms of features, and with harsh new legislation coming in from places like California, maybe it is time to start looking at e-bikes that are light, efficient, and smooth rather than how much wattage they can output. The Tenways CGO 600Pro, which comes in at just 37 pounds, is a model e-bike you should keep an eye on…
The CGO 600Pro comes in 2 flavors: a carbon belt single-speed version that Micah reviewed and this one, which is a chain and 8-speed Shimano gears. The belt drive is going to win out on simplicity and weight but if you are expecting to get close to the ‘class 1’ top speed of 20mph or need to go up some significant hills, you’ll want to opt for the chain/gear version here.
One thing I love about this bike is the tradeoff decisions. These keep the price low and weight down while still providing a great ride. The spec sheet overall is solid but not top-shelf.
Tenways CGO600 Pro tech specs (chain/geared version)
- Motor: 350 Watt rear hub motor with 45 Nm of torque
- Top speed: 20 mph (32 km/h)
- Range: Claimed up to 53 miles (85 km)
- Battery: 36V 10Ah (360 Wh)
- Weight: 37 lb (16.8 kg, over 40lbs with fenders, kickstand, etc)
- Frame: 6061 aluminum alloy
- Tires: CST Puncture-proof 700*45C-size Tires
- Brakes: Tektro dual-piston hydraulic disc brakes
- Gearing: Shimano 8-Speed Claris
- Extras: Compact LED display, 4 pedal assist levels, slim fender set, kickstand, internally routed cables, LED lighting, removable battery, Tenways app integration, torque sensor, four color options
No Throttle?
Note that as a class 1 e-bike, neither belt/chain version has a throttle. While this may be controversial to some, it not only simplifies the bike, it makes it a Class 1, which will be legal in the most places. I tend to think of no throttle as a “foot throttle” and for the commuter application, this will serve well. Would I appreciate a throttle on a hill start? Perhaps.
The idea of this bike is to just enhance your pedal bike experience. You are going to get some exercise on this bike versus a bike that is a glorified low-power moped that runs on throttle with vestigial pedals.
More importantly, the torque sensor here is phenomenal; I mean, it is probably the best torque sensor I’ve ridden connected to a rear hub motor. The acceleration is smooth and strangely powerful for the 350W/45nm motor. Significant hills are a breeze, and this is one of the few bikes where I forget that I’m using an e-bike sometimes (until I look down and I’m going 20mph with little effort). Hills are also where the gearing really helps.
The tires are also the perfect size for a commuter with puncture resistance and treads that will do OK in rain and snow.
The bike itself is also very stealthy in terms of showing that it is a powered e-bike. The small 36V, 10Ah battery is integrated magnificently into the narrow downtube of the bike. All of the cables are integrated into the bike frame for a super-clean look. The rear hub motor is small but packs a punch. Many people won’t even recognize this as an e-bike. While I’m proud to be riding an e-bike around, perhaps some people would like to keep that on the down-low.
Brakes are great with hydraulic Tektros clasping against 160mm rotors in front and back. It is such a light bike that stopping can be jarring.
Assembly was super easy and took about 30 minutes with the included tool set. The battery came about 40% charged but was ready to go within a few hours with the 3A charger. Shoutout to Tenways for using a water-resistant standardized barrel charger adapter and not some proprietary adapter so that I can use one from another bike when I inevitably lose it.
Electrek’s take
The Tenways CGO600 is a fantastic light, clean, stiff and smooth e-bike that I have 0 reservations about recommending. While the battery and motor are small, they power the light bike admirably and for around 50 miles (your mileage will vary).
Currently there is a $200 off promotion code “HAPPY2025TW” at checkout bringing the CGO600Pro down to $1399 which is an amazing price for this bike:
