Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source

Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source

What Is Osmotic Power and How Does It Work? Osmotic power (or salinity gradient energy) is electricity generated from the natural process of osmosis – the movement of water across a membrane from a dilute solution to a salty solution theguardian.com. At river deltas where freshwater meets the ocean, immense chemical energy is continuously released as the two mix. Osmotic power plants capture a portion of this energy by separating fresh and salt water with special membranes in a controlled setting theguardian.com. The concept has been studied since at least the 1970s, but only in recent years have technological advances

Electrifying Europe: 2025’s Best Electric Cars – Range Kings, Affordable EVs & Game‑Changers

Key Facts Europe’s EV Market in 2025: A Breakout Year Electric vehicles hit the mainstream in Europe by 2025, marking a breakout year for electrified transport. After years of double-digit growth, EVs now account for roughly 15–20% of new car sales across the EU (and climbing fast) best-selling-cars.com best-selling-cars.com. In the first half of 2025 alone, over one million battery-electric cars were sold in Europe – a new record best-selling-cars.com. This momentum comes even as the overall car market remains slightly below pre-pandemic levels, indicating that EVs are grabbing market share even in a lukewarm economy. Notably, Europe is now

Your Next Rooftop Will Be a Power Plant. Rooftop Energy Technologies: Present and Future Innovations.

Your Next Rooftop Will Be a Power Plant. Rooftop Energy Technologies: Present and Future Innovations.

Solar PV costs have fallen about 90% over the last decade. Modern home solar panels often exceed 20% efficiency, with typical residential systems of 5–10 kW. In the United States, over 4 million homes had solar panels by early 2024. Global rooftop PV adoption could reach about 100 million households by 2030. In the United States, the rooftop solar roofing market is projected to reach nearly $1 billion by 2025, as California mandates solar on almost all new homes starting in 2023. A Dutch startup unveiled the Blade X1 rooftop wind turbine at 1.4 meters tall, generating about 2,500–3,000 kWh

This New Solar Panel Tech Works Even at Night

This New Solar Panel Tech Works Even at Night

Thermoradiative energy generation, nicknamed night-time solar, produces electricity by emitting infrared radiation to the cold night sky when the device is warmer than its surroundings. Unlike conventional solar cells that absorb sunlight, thermoradiative devices emit photons to space, effectively running as a solar cell in reverse and using the Earth–space temperature difference at night. In 2020, Jeremy Munday and colleagues proposed an anti-solar cell that could theoretically produce up to about 50 W/m² at night under ideal conditions. In 2022, UNSW Sydney demonstrated the first unambiguous lab power from a thermoradiative diode using mercury cadmium telluride (HgCdTe), generating nanowatts and

Technology Trends 2025: Global Innovations in AI, Green Tech, Space, and More (Updated: June 27th, 2025)

The global AI market is estimated at $758 billion in 2025 and is projected to rise to multiple trillions in the next decade. Apple’s 2025 software enables an iPhone to run a local large language model for Siri, marking edge AI in consumer devices. The AI semiconductor market is projected to exceed $150 billion in 2025 as cloud data centers invest heavily in AI processors. In May 2025, scientists delivered the world’s first personalized CRISPR gene therapy to a one-year-old boy with a rare genetic disease, halting disease progression. In June 2025, Insilico Medicine announced positive Phase II results for
