The human brain can generate about 20 watts of electrical power enough to power a small LED lightbulb This electricity is produced by the synchronized firing of roughly 86 billion neurons, each one acting like a tiny biological battery pumping ions across membranes to create voltage spikes. When you have a thought form a memory or feel an emotion what's actually happening is an electrochemical cascade sodium and potassium ions rushing through protein gates creating waves of depolarization that ripple across neural networks at speeds up to 268 miles per hour. The combined electrical activity of your brain at any given moment could theoretically charge a smartphone battery over the course of a few days.

The Kampala Entebbe Expressway is now illuminated, with the Northern Bypass set to follow suit. Given its cost-effectiveness and low maintenance, some may wonder why solar lighting wasn't utilized. The first challenge is solar energy, which faces intermittent generation and varying sun hours in different regions. In Kampala, the average sun hours generating light is 3.5 to 4 lux, compared to 6 in Northern Uganda. Seasonal variations further impact consistency, making maintaining the recommended 40-70 lux lighting for expressways throughout the night challenging. This inconsistency poses safety concerns on high-speed roads. Second challenge Vandalism is another issue, as batteries used in solar lighting can be targeted for resale at 12Volts /24Volts. Despite efforts to deter vandalism, the challenge persists. Telecom towers, which also use solar, avoid this issue due to continuous monitoring, which can't be done for a road with 180 lights and less marketable 48Volt inverters. These things are hard to sell. The final Challenge is maintenance and durability. Uganda is a country of pollen, dust and grime. Regular checks on battery efficiency, cleaning of solar panels, and monitoring darkness sensors are essential in our dusty environment. Standard lighting may be simpler to maintain, focusing mainly on the bulb. While solar may be unavoidable in remote and hard-to-reach areas, the initial installation cost, inconsistent light output and maintenance challenges currently make grid power a more practical choice. While there have been successful solar implementations on a global scale, the widespread adoption of solar technology is still in its nascent stages. Notable examples include the A14 in England, where a section incorporates solar lighting, a 24km expressway in Chile that utilizes solar panels, and a segment of Interstate 10 in Arizona dedicated to illuminating wildlife crossings using solar power. These cases illustrate promising strides in integrating solar solutions, yet comprehensive deployment is yet to reach maturity. The transition to renewable energy is seen as inevitable, but for now, standard roads are better suited for solar lighting with manageable lux and duration requirements, e.g. Kira Matugga KCCA roads.

Germany currently has about 26 gigawatt hours of battery storage. Most of it sits in home batteries with only 4.3 gigawatt hours actually serving the grid. Building that storage already cost more than 10 billion euros and at national demand levels it only covers roughly 30 minutes of summer electricity usage. The winter months bring what's known as "Dunkeflaute" - cold dark windless periods and higher energy usage. To survive a 10-day winter lull (the minimum realistic requirement), Germany would need about 12,000 gigawatt hours of batteries, 470 times today's storage. Such a system would weigh roughly 60 million tons and would be made from vast quantities of lithium, nickel, graphite, copper, aluminum and steel, all requiring intensive mining. At current battery prices, the system would cost trillions of euros. And batteries last only 10 to 15 years, meaning the entire system would need constant replacement. The conclusion is unavoidable... Wind and solar require reliable backup power, renewables need oil, coal, gas and nuclear.

A rare insight into the AN/PRC-10 field radio used in Korea and early Vietnam war, mainly built by General Electric. A 1950s vacuum tube man-pack system, fully assembled and wired by hand, built around 16 subminiature vacuum tubes with no semiconductors, no digital control, and no onboard computation. To operate, it required a stacked multi voltage battery system producing 1.5V, 6V, 67.5V and 135V simultaneously, just to keep analog amplification and RF stages stable in field conditions. For scale, a modern smartphone battery like an iPhone stores roughly 10 to 12 watt hours of energy in a compact lithium cell. The PRC-10 was operating with far lower usable power output, around 1 watt of transmission power, but in a completely discrete high voltage analog architecture. Each unit costed roughly $300 to $430 in 1950s terms, about $4K to $5K today, not because of electronics complexity in the modern sense, but because every radio had to be individually hand calibrated for frequency stability and field reliability all built by hand. In practice, systems like this gave US infantry units reliable 5 to 12 km communication in terrain where coordination with artillery and manoeuvre units directly influenced survival outcomes. What looks like simple battlefield equipment today was a fully hand built analog communication system that carried command decisions across entire units in real time. 🎥Biofab138

California's $2.2 billion solar plant is shutting down. Once hailed as a breakthrough, the Ivanpah Solar Facility in the Mojave Desert is now a case study in failed technology and environmental risk. Built with $1.6 billion in federal loans in 2014, the plant was hailed as a symbol of America's clean energy future. It used 173,000 mirrors to focus sunlight onto three massive towers heating fluid to drive steam turbines. Complicated. Expensive. And it never delivered on its promise. After just 11 years, the technology is now obsolete. On top of that, the facility became notorious for its environmental toll, with estimates of at least 6,000 birds incinerated each year by the concentrated beams. The promise was affordable, reliable, green power. The reality was high costs, technical failures and ecological damage.

The solar tax credit cliff is coming. But as prices rise, the economics of solar are still moving the right way, for those businesses that can reduce costs and survive. Bret Biggart of Freedom Solar Power told me: “If you can make it through these next challenges, the horse has left the stable for solar.” Even with federal tax credits expiring, the underlying math still works. Because when you strip it down, solar economics hinge on two numbers: ⚡ Cost to install per watt ⚡ Price of electricity If installation costs keep trending down and power prices keep trending up, the curve favors solar, especially in sunny Texas. ✅ Short-term: panels and components are pricier due to inflation, tariffs, etc. and margins are tight. ✅ Medium-term: power costs increase from IRA repeal and continued tariffs, inflation, etc., competition and innovation force solar costs down. ✅ Long-term: solar grows even faster. The transition won’t be painless. But as Bret put it, those who endure the “last punch in the face” will be standing in a stronger industry. One that’s leaner, cheaper, and more resilient. 👉 Full conversation in the comments. #TexasEnergy #TxEnergy #SolarEnergy #CleanEnergy #EnergyTransition #EnergyPolicy #txlege

You will remember that a month or two ago, I posted about the solar system at my home in Johannesburg, which has allowed me to hardly use Eskom or City Power because it generates enough energy for my entire usage, including powering geysers. After that post, one of you on this page, a solar expert, reached out privately and advised me to remove the electric geysers from the main solar system. He said the solar batteries were doing too many cycles because they were powering the geysers, and that this would shorten their lifespan. His advice was simple, remove the geysers from the battery load if I wanted the batteries to last the full period that they are built for. I took that advice seriously. I then asked my plumber, Shanil, who owns Metro Plumbers, to guide me on where to get high-quality solar geysers in Johannesburg so that I could replace the electric ones. Shanil told me about a new technology called the Elon Smart Solar PV System. He explained that it is much cheaper than buying completely new solar geysers. Instead of replacing the electric geyser, you simply buy the Elon unit, which comes with its own solar panels, and it is fitted onto your existing electric geyser. That is what I did. I have now removed all four electric geysers from the home solar system that powers my home. Each of them has been converted using the Elon Smart Solar PV technology. They are now powered by their own dedicated solar panels. The four geysers are running on a total of thirteen panels. So what this means is that I will never use Eskom or City Power again because in the past, when it was cloudy for three or four days, I would return to the grid to assist the batteries. This was happening because the batteries were carrying a heavy load that included four geysers. Now that the geysers have been removed from the main solar system and converted to their own dedicated solar supply, I will never return to Eskom or City Power. Even on cloudy days unless the solar system breaks down. The system is able to generate enough power for everything that I need. I also use a gas cooker, which helps reduce the electrical load. I hope this information helps you. If I had gone for the top-quality geysers that are exclusively solar, I would have paid between R25,000 and R30,000 per geyser. That would have come to around R120,000 for four geysers. Of course, there are cheaper solar geysers that you can get, but they are cheaper for a reason. So, in essence, I saved half the amount I would have paid for the geysers if I had chosen top-quality solar geysers. If you are in Johannesburg and you are interested, Shanil’s number is +27 (76) 890-5582. He can do the work for you. The gadgets and their panels cost R60,000 from Plumbing Supplies Sanitaryware Centre in Woodmead. So I have had the system in place for a week now and it is working very well. I have deliberately allowed all the geysers to continue heating so that I could test whether everything is functioning correctly, and the water is as hot as it should be. So that is the story. I thought I should share it with you for those who might want to reduce their bills. P/s The other interesting key feature of this system is that I can control it from my phone. If it is very cloudy and the water is not as hot as I want it to be, I can simply go onto the app and instruct that particular geyser to use the grid. Unlike my previous setup, where I had to switch the whole home solar system onto the grid, now each individual geyser can independently switch to the grid and heat the water to a temperature that I have set. Once the water reaches that set temperature, it automatically disconnects. I can also decide to switch off a geyser from using electricity, in my case from my solar system, or for those who do not have solar systems, from Eskom. In the same way, I can switch it off from using the solar panels. For instance, if there are four geysers and one of them is in a bedroom that is not being used, I can switch off that geyser completely so that it is not heating water unnecessarily. This gives you control, flexibility, and saves you a lot of money in the long run. You can read more about this technology here;

You will remember that a month or two ago, I posted about the solar system at my home in Johannesburg, which has allowed me to hardly use Eskom or City Power because it generates enough energy for my entire usage, including powering geysers. After that post, one of you on this page, a solar expert, reached out privately and advised me to remove the electric geysers from the main solar system. He said the solar batteries were doing too many cycles because they were powering the geysers, and that this would shorten their lifespan. His advice was simple, remove the geysers from the battery load if I wanted the batteries to last the full period that they are built for. I took that advice seriously. I then asked my plumber, Shanil, who owns Metro Plumbers, to guide me on where to get high-quality solar geysers in Johannesburg so that I could replace the electric ones. Shanil told me about a new technology called the Elon Smart Solar PV System. He explained that it is much cheaper than buying completely new solar geysers. Instead of replacing the electric geyser, you simply buy the Elon unit, which comes with its own solar panels, and it is fitted onto your existing electric geyser. That is what I did. I have now removed all four electric geysers from the home solar system that powers my home. Each of them has been converted using the Elon Smart Solar PV technology. They are now powered by their own dedicated solar panels. The four geysers are running on a total of thirteen panels. So what this means is that I will never use Eskom or City Power again because in the past, when it was cloudy for three or four days, I would return to the grid to assist the batteries. This was happening because the batteries were carrying a heavy load that included four geysers. Now that the geysers have been removed from the main solar system and converted to their own dedicated solar supply, I will never return to Eskom or City Power. Even on cloudy days unless the solar system breaks down. The system is able to generate enough power for everything that I need. I also use a gas cooker, which helps reduce the electrical load.

Does the world have enough lithium to power all the electric vehicles and stationary batteries needed to transition the world to 100% clean, renewable energy and storage for everything? The answer is yes. In 2025, the USGS increased its estimate of world lithium resources over land by 30%, to 150 million tons, with the U.S. having the largest resource, 30 million tons, followed by Argentina, Bolivia, Chile, Australia, and China. How much lithium is this? The world has 1.1 billion passenger cars and 375 million trucks and buses. Replacing these requires about 47 million tons of lithium -- 9 million tons for the cars and 38 million tons for the trucks and buses. That’s only 31 percent of the 2025 known lithium resources, and keep in mind, the known resources grow each year as people look for more lithium. What is more, lithium stays in a vehicle during a battery’s 15 to 25-year life. At the end of the battery’s life, the battery is recycled or re-used for stationary electricity storage, so the mining is one-time. For stationary electricity storage itself, less than one-tenth the lithium, 2 to 4 million tons, is needed worldwide than is needed for vehicles. As such, current lithium resources are over three times those needed for vehicles plus storage. Also, many other battery types now exist that don’t use lithium. In sum, there is no shortage of lithium to transition the world to 100% clean, renewable energy and storage for everything. More info Video:

THE SOLAR SYSTEM IS OFFICIALLY A HARDWARE STORE: DISMANTLING THE PLANETS TO POWER THE FUTURE The conversation about Dyson Swarms has shifted from science fiction to a logistical reality of "when," not "if". While covering the sun in a solid shell is a structural nightmare, a Dyson Swarm, a network of independent solar collectors, is the pragmatic path to a Type II civilization. Elon accelerated this timeline, suggesting Starship could deploy solar harvesting satellites delivering 100GW per year to Earth orbit within the next four to five years. But if we are talking about a true, star encompassing swarm, the 50 year sprint begins with Mercury as the ultimate sacrificial planet. It is metal rich and sits at the perfect distance from the sun to minimize energy costs for launch. Automated robots would mine Mercury’s crust, refine materials on site, and launch solar panels into a statite orbit using radiation pressure to maintain position. Disassembling just half of Mercury provides enough material for a swarm capturing a billion times more energy than Earth currently receives. Asteroids are the "fantastic food source" for this construction because they are a non starter for gravity wells. Mining an asteroid like 16 Psyche is infinitely more efficient than fighting the gravity of a planet like Jupiter. Most asteroids are already sorted into carbonaceous fuel or nickel iron kits, making them perfect modular factories for solar panels. While we harvest these dead rocks and the asteroid belt, habitable candidates like Mars will be left untouched. Source: Moonshots Peter H. Diamandis, MD
