After analyzing the physics detailed in this video, I’m convinced it is solar energy that drives the observed ocean heating, and any infrared ocean heating is insignificant at best.

ARON - or Augmented-Reality Optical Narrowcasting - is a new communications channel that operates without relying on cellular networks or the Internet, instead utilizing infrared light...

Waste heat could be a valuable source of energy - if only we could find a way to capture it efficiently. Now two Duke University researchers have a plan to do just that. They have developed a new thermophotovoltaic device...

A sunlight-harvesting technology created by researchers in Los Alamos and Italy could turn any window into a solar energy source. The technology is based on tiny nanoparticles known as quantum dots, which can absorb sunlight...

Light Bulb Back Radiation Experiment Guest essay by Curt Wilson In the climate blogosphere, there have been several posts recently on the basic principles of radiative physics and how they relate to heat transfer...

As readers may know, Dr. Roy Spencer and I have had a long running disagreement with the group known as “Principia Scientific International” aka the Sky Dragon Slayers after the title of their book. While I think...

By WUWT regular “Just The Facts” We are pleased to introduce an array of upgrades to the WUWT Sea Ice Page, including: Arctic Sea Ice Thickness: From the Naval Research Laboratory (NRL) – HYCOM Consortium...

From AGU highlights, interesting, but readers should note that this is one point on Earth in Chile, not a summation of the  atmospheric absorption, emission, and transmission of infrared radiation for the entire globe...

Guest post by Ira Glickstein A real greenhouse has windows. So does the Atmospheric “greenhouse effect”. They are similar in that they allow Sunlight in and restrict the outward flow of thermal energy. However,...

A guest post by Ken Coffman and Mikael Cronholm In clicking around on the Internet, I found an outstanding paper called Thermodynamics of Furnace Tubes – Killing Popular Myths about Furnace Tube Temperature Measurement...

Have you ever wished that your car windshield or cell phone camera could pierce through the night and turn darkness into day? Then get ready: researchers at the University of Florida have figured out a way to create ultra...
