Japanese engineers developed a solar cell thinner than a human hair that wraps around any curved surface and converts sunlight to electricity more efficiently than the rigid glass panels

 

Japanese engineers developed a solar cell thinner than a human hair that wraps around any curved surface and converts sunlight to electricity more efficiently than the rigid glass panels it is designed to replace — transforming every surface in the world into a potential power generator.

Researchers at RIKEN Institute developed perovskite solar cells deposited on a plastic substrate 2 micrometers thick — 25 times thinner than a human hair — through a room-temperature manufacturing process using liquid precursor solutions rather than the 1,400-degree silicon purification that makes conventional panels expensive and energy-intensive to produce. The ultra-thin cell achieves 26.1 percent power conversion efficiency — exceeding the 22 percent best commercial rigid silicon panels — because perovskite's superior light absorption properties are enhanced rather than compromised by the flexible substrate. The cell bends repeatedly to a 3-millimeter radius without degradation over 10,000 flex cycles, allowing permanent installation on vehicle bodies, aircraft wings, building facades, backpacks, clothing, and any other surface where weight and rigidity preclude conventional panels.

Manufacturing cost of the flexible cell reaches $0.12 per watt — compared to $0.28 per watt for rigid commercial silicon — because the room-temperature solution process requires no specialized high-energy manufacturing equipment. RIKEN estimates a car body fully covered in these cells generates 3.2 kilowatts continuously in full sun — equivalent to a slow home EV charger — from surfaces previously contributing zero energy.

Toyota and Honda have signed exclusive development partnerships for automotive applications beginning in 2026.

Artemis 2 humans return to the Moon.

 

Today, humans return to the Moon.

NASA is going to launch the first crew of astronauts toward the moon in over 53 years.

Three U.S. and one Canadian astronaut ‌are due for liftoff aboard NASA's Orion capsule and Space Launch System rocket today for a 10-day mission swinging around the moon and back.

Liftoff is scheduled for April 1, though it could happen any day after until April 6, depending on weather conditions in Florida and any last-minute snags with the rocket.

You can watch live on the NASA website and social channels.

Netherlands just activated the world's most extensive underground geothermal district heating network — 2,400 kilometers of insulated pipes delivering natural Earth heat to homes, schools, hospitals, and businesses

 

The Netherlands just activated the world's most extensive underground geothermal district heating network — 2,400 kilometers of insulated pipes delivering natural Earth heat to homes, schools, hospitals, and businesses across the entire country with zero carbon emissions and dramatically reduced energy bills.

The Netherlands Deep Geothermal Network draws hot water at 80 to 95 degrees Celsius from aquifer formations 2,000 to 3,500 meters below the flat Dutch landscape, circulating it through a nationwide insulated pipe network before returning cooled water to the aquifer in a closed system that neither depletes nor contaminates the geological resource. The Dutch geological survey identified 340 viable geothermal production sites distributed evenly across all 12 provinces, enabling a decentralized network architecture where every community receives heat from a local source rather than depending on a single central facility. Each production site serves a cluster of 15,000 to 40,000 homes through local distribution networks connected to the national backbone.

Dutch households previously paying average annual heating bills of 1,900 euros now receive geothermal heat at equivalent delivery cost of 420 euros annually — a 78 percent reduction that is permanent and independent of international gas price fluctuations. The Netherlands imports 85 percent of its natural gas, making heating costs highly vulnerable to geopolitical supply disruptions. Domestic geothermal eliminates this vulnerability entirely while reducing national carbon emissions by 22 million tons annually.

The complete network took 11 years to plan and 6 years to construct, representing the Netherlands' largest infrastructure investment since the Delta Works flood protection program.

European autonomous strike TigerShark cruise-missile can reach speeds of 750 km/h , range exceeding 1,000 km can carry a 300 kg (661 lbs) warhead

 

Marking what defense analysts are calling the most significant advance in European autonomous strike technology in over a decade, MGI Engineering successfully completed the first flight of the TigerShark uncrewed deep-strike platform on April 1, 2026. Developed in a strategic partnership with the Swiss-American software firm Auterion, the TigerShark represents a new class of "software-defined" weaponry designed to provide cruise-missile-like lethality at a fraction of the traditional cost.

The milestone arrives as European nations scramble to replenish munitions stockpiles depleted by regional conflicts and seek a low-cost counter to sophisticated integrated air defense systems (IADS).

The TigerShark is not a typical tactical drone; it is a high-speed, one-way "effector" engineered to strike high-value targets deep behind enemy lines.

Mach-Speed Capability: Powered by twin small gas turbines and launched via rocket-assisted takeoff (RATO), the TigerShark can reach speeds of 750 km/h (466 mph).

Payload and Range: The platform can carry a 300 kg (661 lbs) warhead comparable to many conventional cruise missiles and has a strike range exceeding 1,000 km (621 miles).

Cost Efficiency: While a standard cruise missile can cost several million dollars, the TigerShark is aimed at a price point of approximately $549,000, enabling "attritable" mass that can overwhelm enemy defenses through salvo tactics.

The "secret sauce" of the TigerShark is its integration with Auterion’s Skynode-N flight controller and open software architecture.

GNSS-Denied Navigation: Engineered for the high-intensity electronic warfare environments seen in 2026, the TigerShark operates effectively in GPS-denied and spoofed environments. It utilizes inertial navigation paired with GPS-free terrain mapping to maintain precision without satellite reliance.

Rapid Iteration: Because the platform is software-defined, new capabilities and mission profiles can be uploaded in days rather than months. Auterion CEO Lorenz Meier noted that the full autonomous integration for the TigerShark took only one week to complete.

Formula 1 DNA: MGI Engineering, founded by former F1 technical director Mike Gascoyne, utilized rapid prototyping and advanced composite techniques from the racing world to build a lightweight, heat-resistant airframe that can be mass-produced quickly.

The successful test in Oxfordshire is being viewed as a "game changer" for European defense industrial strategy, which has historically struggled with slow, expensive procurement cycles.

The "Quantity is Quality" Shift: Defense officials are moving away from treating drones like "Rolls-Royces" and toward treating them like "rifles" tools that are available in volume and designed for high-throughput production.

The Ukraine Influence: The TigerShark’s development has been heavily informed by the 2024-2025 conflicts in Eastern Europe, where low-cost autonomous systems successfully penetrated "sophisticated Western air defenses." Reports indicate MGI is already exploring plans to supply these systems to the Armed Forces of Ukraine for combat testing.

Allied Integration: Designed with a Modular Open System Architecture (MOSA), the TigerShark is fully interoperable with third-party sensors and EW payloads, making it an ideal candidate for NATO-wide scalable procurement.

In 2026, the successful flight of the TigerShark signals that Europe has finally entered the era of autonomous deep strike. By marrying British Formula 1 engineering with Auterion’s battle-hardened AI software, MGI has created a weapon that is cheaper than a cruise missile but deadlier than a standard drone. As the company moves toward a projected October 2026 availability, the TigerShark stands as a warning to any adversary: the "invisible" front line now extends 1,000 kilometers deep, and it moves at 750 kilometers per hour.
