New Haven turned a landfill that stopped accepting trash more than 20 years ago into a solar farm with over 1,900 panels, enough to generate the equivalent annual electricity use of about 200 homes while bringing the city $72,000 a year in rent
Nearly 5,000 solar panels were installed on a Swiss dam 8,200 feet above sea level, and despite deep snow and freezing temperatures the Alpine plant produced 3.8 times more winter electricity per unit of capacity than a lowland installation during its first measured year
A Swiss greenhouse installed 1,736 solar modules above working tomato crops and produced up to 1 MWh of electricity a day while cutting summer grid use by 35%, yet the surprising result was that tomato yields did not fall and were actually 1% higher
A Massachusetts farmer grows sweet corn under 832 solar panels raised 10 feet above the soil, and he still harvests 80% of what the open field next door gives him
Colorado researchers grew saffron beneath semi-transparent rooftop solar panels and harvested twice as many flowers and twice as much dried spice as unshaded plots, with a five-year model projecting about $61,000 from electricity, saffron and new plants
The world’s largest working cattle station spans about 6,080 square miles and holds 17,000 cattle, yet its headquarters runs mainly on just 49 kW of rooftop solar and batteries, with careful planning essential because forgetting one critical part can mean a 1,120-mile round trip
New York demolished all seven turbines at its pioneering Madison wind farm in just 30 seconds after 25 years of operation, but a proposed neighboring project with nearly seven times the capacity now has its grid-connection application listed as withdrawn
A 12.75-inch underwater robot autonomously entered a submerged 21-inch torpedo-tube test fixture in New York and then backed itself out, a precision maneuver that could eventually let U.S. submarines launch and recover drones without sending divers into the water
An Ohio solar farm now shares its 196-megawatt site with more than 50 beehives and nearly 3 million honey bees, turning land around the panels into pollinator habitat while veteran beekeepers use the project to train other veterans and first responders in caring for colonies
Scientists built the first all-optical photonic time crystal by making a material change its optical properties every trillionth of a second, and the strange experiment cut losses in light-and-electron oscillations by more than 50% while opening a possible path toward new terahertz lasers
Researchers studied 200 wind turbines rising above Iowa corn and soybean fields for two summers and found they could cool the air by up to 0.75°C during the day and warm it by 1.5°C at night, but whether that actually produces more corn remains unanswered
In 1999, workers filled a 42-foot nuclear reactor vessel with 200 tons of concrete and moved the 1,020-ton package 300 miles by barge and a 320-wheel trailer, but 791 spent fuel assemblies from the same Oregon plant are still waiting in storage today
Sweden imported 3.86 million metric tons of other countries’ waste in 2024 and gets paid to burn it for heat and electricity, but the system still releases fossil CO2 and is not the same as recycling
South Fork Wind’s 12 turbines off Long Island are already working as artificial reefs, and black sea bass catches were ten times higher at nearby Block Island, but scientists warn that more fish around a turbine doesn’t mean more fish in the ocean
Texas ranchers sued to stop 46 wind turbines near the Devils River, conservationists worry about a cave once home to 250,000 bats, and a study shows a simple change could cut bat deaths by 62%
More than 23,000 solar panels have floated on a reservoir outside London since 2016, generating enough electricity for roughly 1,800 homes while using less than 10% of the water’s surface, and research suggests the shade beneath them could also reduce evaporation
Radia is designing a 356-foot cargo plane with a 261-foot wingspan to carry 344-foot wind turbine blades where trucks cannot go, then land on a 6,000-foot dirt runway built beside the wind farm instead of a conventional airport
