Climate Change Heat Destroys British Warships

Courtney Lepping — Tue, 14 Jun 2016 06:24:54 +0000

The ocean temperature in the body of water called the Persian Gulf has recently skyrocketed to the point of causing the breakdown of six Type 45 British warships. Unbelievably, the ships are prone to losing power from the drastic changes. Although the water temperatures in the Persian Gulf typically range from 75 to 90 degrees […]

The Future Effect of Climate Change on Life in the Middle East

Annika Tostengard — Fri, 06 Nov 2015 14:06:30 +0000

Scientists have been examining how climate change will effect southwest Asia and the results are alarming. The Middle East could quickly become inhospitable for all practical intents and purposes. Published in Nature: Climate Change, the studies examined both how the climate in southwest Asia will respond to varying levels of carbon dioxide emissions and at exactly what […]

Converting Heat To Electrical Power Efficiently Using Quantum Dots

Mila Luleva — Thu, 14 Feb 2013 22:39:02 +0000

Microcircuits might become much more efficient, with the development of a new type of nanoscale engine, which uses quantum dots to generate electricity. Professor Andrew Jordan, a theoretical physics of the University of Rochester explains that the system is simple and it is based on particular properties of quantum dots, which harvest heat. But simple, […]

Heat in Large Cities Affects Temperature Miles Away

Mila Luleva — Mon, 28 Jan 2013 20:41:35 +0000

A study published in Nature Climate Change last week reveals that human activity in major cities has a direct influence on temperature across thousands of miles. Activities in the metropolitan areas affect major atmospheric systems and either warm or cool areas further away. The study by scientists at the Scripps Institution of Oceanography, University of […]

Treating Heat Just Like Light Yields New Thermoelectric Applications

Mila Luleva — Fri, 11 Jan 2013 19:15:25 +0000

New research coming from MIT’s Department of Materials science and engineering, reveals a technique that allows manipulation of heat so that it can be controlled as light waves. The author, Martin Maldovan, a researcher at the institute, engineered materials that consist of nanostructured semiconductor alloy crystals. Considering that heat is basically a vibration of matter, […]

BluBox Thermal Fan Takes Heat from Ceiling to Floor

Ovidiu Sandru — Mon, 23 Jan 2012 19:08:23 +0000

The warmest (and most expensive) air in your home (or small business) is lazily floating around above your head looking for some way to escape. This is especially true if you make your heat with a Single Point Source (wood burning stove, floor furnace, wall furnace, etc.) or you have high ceilings, or (who would […]

Everything We do Emits Heat – Bad in the Long Run, or Not?

Ovidiu Sandru — Mon, 01 Dec 2008 08:06:05 +0000

I don't know what to believe anymore, sometimes. We seem to run of global warming, we reduce pollution and try to "green" ourselves through electric cars, solar cells and wind mills, yet scientists (as if all this global warming mess is all on their football field) say there will still be global warming due to the heat our machines, as a whole, emit in the ecosystem.

The Spin Seebeck Effect to Offer Low-Loss Thermoelectric Effect

Ovidiu Sandru — Mon, 13 Oct 2008 18:19:18 +0000

Eiji Saitoh experimented with a heated magnetized metal (nickel-iron), and found out that the electrons with up spins (aligned with the rod's magnetic field) created an agglomeration on the hot side, while the ones with down spins (unaligned to the rod's magnetic field), created an agglomeration on the cooler side.

Solar Powered Inflatable Heater

Ovidiu Sandru — Sat, 26 Apr 2008 19:08:31 +0000

Meet the new invention of the 21st century. It is a solar heater. The basic principle is pretty simple: water is stored in a bed-sized floating bag, which looks like this: The Sun’s light passes through the transparent plastic, heats up the water inside the black tubes, and then it’s passed on to the heating […]

Body Heat to Electricity: German Scientists Working on Viable Design

Ovidiu Sandru — Fri, 21 Mar 2008 05:41:32 +0000

German scientists have found a way of transforming body heat into electricity using thermoelectric devices. The discovery means that we may be able to operate our mobile phones using nothing but the warmth of our hands in the future. New circuits make it possible to harness body heat for generating electricity, scientists at the Fraunhofer […]

MSI To Make Self-Cooled Stirling Engine Motherboards

Ovidiu Sandru — Sat, 01 Mar 2008 16:59:54 +0000

If you ever had to do with a computer, or with buying a computer by parts, then you surely have heard of MSI. They are a big Taiwanese manufacturer of computer motherboards (those boards that you put your microprocessor and memory on). They’re not on the top of quality and performance, but they sell well, […]

The Tornado Solar Tower: Get Power From Recycled Heat

Ovidiu Sandru — Sun, 10 Feb 2008 20:10:18 +0000

Did you know electrical power can be generated by using various sources, including the sun, wind, warm air from the ground? The list goes on… The most interesting is the tower resemblant to a solar tower, in which a controlled tornado is created. Engineer Luis Michaud, from Canada, who has proposed this system, has already […]
