Laser Beams from Space: Aetherflux’s Solar Vision

-

A California startup named Aetherflux is making headlines with a daring plan: by 2026, it wants to launch mini solar farms into low Earth orbit and transmit energy back to Earth using laser beams. The company, backed by major investors and powered by the vision of Robinhood co-founder Baiju Bhatt, believes this approach could open a new era of continuous clean energy. (CNBC)


How It Works

Unlike ground-based solar panels, orbital solar arrays can capture sunlight without clouds, weather, or night interrupting them. The satellites convert sunlight into electricity, then into infrared laser beams, which are sent to receivers on Earth. These receivers turn the laser light back into usable electricity for grids or off-grid locations. (New Atlas)

Why SpaceX?

To reach orbit, Aetherflux will rely on SpaceX rockets, leveraging lower launch costs that make experimental projects like this possible. The company plans test flights by 2026 to prove that orbital beaming is not only possible but scalable. (TechCrunch)

Price Tag and Economics

Cost remains the biggest question. According to early estimates, orbital solar power could be 12 to 80 times more expensive than ground-based renewables. Building satellites, launching them into orbit, and maintaining laser precision is costly. Yet, Aetherflux argues that USD $50 million in recent funding is only the start, and prices will fall as technology improves. (PV Magazine)

Potential Uses

  • Providing emergency power to disaster zones
  • Supplying electricity to military bases in remote regions
  • Supporting research stations in polar or oceanic areas
  • Reducing dependence on fossil fuels for hard-to-reach places

Challenges

Technical and regulatory hurdles are enormous. Lasers must remain perfectly aligned with ground stations, even as satellites orbit at thousands of kilometers per hour. Weather, clouds, and atmospheric scattering may interfere. Safety regulators must also ensure that high-power beams do not pose risks to aircraft or people. (Payload Space)

Expert Opinions

Critics say the economics don’t add up — ground solar, wind, and storage will remain far cheaper for decades. Others argue that niche markets like defense, emergency relief, and space settlements could justify the cost. Supporters note that nearly all radical technologies begin as expensive experiments before scaling down in cost. (Freethink)

Graphics & Visual Concepts

Concept art from Aetherflux shows satellite constellations orbiting Earth, capturing sunlight, and projecting thin red beams toward circular receivers on the ground. These images illustrate a futuristic yet feasible energy transfer system — a blend of science fiction and cutting-edge engineering. (ESA)

Looking Ahead to 2026

All eyes are on Aetherflux’s first test. If successful, it could mark the birth of a new energy industry. If it fails, it will still provide valuable data for future efforts. Either way, 2026 could be remembered as the year laser-based space solar power took its first real shot at becoming reality.

Conclusion

Space-based solar power may sound like science fiction, but with SpaceX, Aetherflux, and investors pushing forward, it is closer to reality than ever. Whether it becomes a global solution or remains a niche technology, it represents one of the boldest attempts to rethink energy in the age of climate change.

The Hidden Threat Beneath the Waves: Exploring the Environmental Impact of Shipwrecks

-

Shipwrecks scattered across the ocean floor may seem like a relic of the past, but today they pose a constant and growing environmental threat. With more than 8,500 shipwrecks lying underwater around the world, these forgotten vessels carry both historical value and environmental hazards. That’s why understanding and addressing this issue is critical to protecting marine ecosystems. The Scale of the Problem Historical records, such as those held by the Lloyd’s Register Foundation in London, and research by experts like Paul Hershink, shed light on the staggering number of shipwrecks. These vessels include warships, cargo ships, and oil tankers, many of which still contain hazardous materials such as fuel oil and chemicals that can pollute the marine environment for decades. The Cost of Inaction The environmental and financial costs are alarming: Dollars: Removing pollutants and salvaging materials from shipwrecks costs millions per ship. For example, cleaning up World War II wrecks can...

The Ethical Dilemma of Mirror Neurons: Why Scientists Are Calling for Their Regulation

-
Image
Mirror neurons are one of the most groundbreaking discoveries in neuroscience. These specialized brain cells fire both when a person performs an action and when they observe another doing the same. While they hold enormous potential for understanding empathy, learning, and even artificial intelligence, some scientists argue that manipulating them poses significant ethical and biological risks. But why should these neurons, essential to human connection, be considered too dangerous for experimentation? What are mirror neurons ? First discovered in monkeys and later confirmed in humans, mirror neurons allow us to “mirror” the actions and emotions of others. They are central to processes such as imitation, emotional contagion, and understanding the intentions of others—cornerstones of human development. However, their potential misuse, such as creating hyperempathic systems or manipulating behavior through advanced technologies, has raised concerns in the scientific community. Why are sci...
