Can one solar collector make both electricity and high-temperature heat?
A hybrid PV-thermal solar collector makes electricity and heat from the same sunlight, and splitting the spectrum lets the solar cell stay cool while the leftover infrared is concentrated into heat above 100 degrees C.
What is agrivoltaics, and can you really farm under solar panels?
Agrivoltaics means farming under or between solar panels on the same land, and field trials show it can work: some shade-tolerant crops yield more, soil holds water longer, and the panels run a little cooler.
How does Doppler shift affect LoRa direct-to-satellite links?
Doppler shift is the main reason LoRa direct-to-satellite links lose packets: a low-orbit satellite moves so fast that the radio frequency a ground sensor hears, and the rate it drifts, can exceed what a LoRa receiver tolerates.
How do you tell how charged a phase change heat storage tank is?
Measuring the state of charge of a phase change heat storage tank means working out how much of the material has melted, and a new infrared camera method does it by watching the melt front directly.
Centimeter GPS over a cheap LoRa radio link
A low-cost RTK setup that sends base-station corrections over LoRa marked planting points to within about 9 cm, but its radio link started dropping a fifth of its packets near 100 m.
Why mosquitoes don't spread Lyme disease
Lyme bacteria have turned up inside mosquitoes, but a set of feeding experiments shows mosquitoes cannot keep or pass them on, leaving Ixodes ticks as the only competent carrier.
How 3D Gaussian Splatting scenes get compressed
Gaussian splat scenes render beautifully but weigh hundreds of megabytes; here is what is inside them, how they are shrunk, and a new codec that guarantees how much each splat can drift.
What makes desktop software easy for AI agents to use
A new study uses a decade of software releases to find the three interface properties that decide whether an AI agent can actually finish a job in a desktop app.
Turning drone video into orthomosaic maps
How a few minutes of drone video becomes a single measurable, map-accurate image — and what to get right before you ever press process.
