In the 1990s when prices of natural gas dropped, so did interest in solar thermal power. Today, though, the technology is poised for a comeback. It's estimated by the U.S. National Renewable Energy Laboratories that solar thermal power could provide hundreds of gigawatts of electricity, equal...

In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as columns of hot air (thermal lift) or air deflected upward by mountainous or ridge topography (ridge lift). As the hang glider and pilot move through the air, they collide with ...
How long does it take to get to Mars & what affects the travel time? The time it takes to get from one celestial body to another depends largely on the energy that one is willing to expend. Here "energy" refers to the effort put in by the launch vehicle and the sum of the maneuver...
The process begins with a high-pressure supply fan that forces exhaust fumes into the Regenerative Thermal Oxidizer. Inlet switch valves direct the pollutant-laden air into one of the energy recovery canisters. The air continues to travel from the valve assembly up through the first heat exchanger...
Such expansion requires energy, and as the total energy in the parcel of air is fixed, it comes at the expense of thermal energy – thus lowering the temperature. Does sound travel further on foggy days? "Sound travels through the air as pressure waves rhythmically moving air molecules back ...
"Light from the sun excites electrons in the atoms which constitute the brick wall. How does that electronic energy get converted to heat, you ask. The key is 'radiationless transitions.' Here's how it works: the atoms of the brick are perpetually vibrating. Some of those atoms vibrate su...
Budapest is famous forits historic thermal baths, but if you don’t want to pay the relatively high entry, try the lesser-known bathhouses. TheDandár Bathsin the XI District are no-frills and cheap – tickets cost 2800 Ft. But you can still visit the big-name baths on a budget: tim...
