Current heat treatments for human tumors, such as radiofrequency, have shown promising results over the last couple of decades, even though they apply only a single-point of heat to the tumor. However, a new technique could prove much more effective by using nanotubes to apply heat throughout the tumor. Scientists found that by injecting the man-made, microscopic carbon tubes into tumors and heating them with a quick, 30-second zap of a laser, they were able to effectively kill kidney tumors in nearly 80 percent of mice.  Read More

A Metal-Organic Heat Carrier (MOHC) molecule that may help improve thermodynamic efficienc...

Geothermal power is cost effective, reliable, and environmentally friendly, but it has previously been limited to geographic areas near tectonic plate boundaries. New technologies, such as that employed in the Raser low-temperature binary geothermal plant, promise to expand the opportunities for geothermal plants. Now scientists at the Department of Energy's Pacific Northwest National Laboratory (PNNL) have devised a method for capturing significantly more heat from low-temperature geothermal resources to further boost the possibility of virtually pollution-free electricity.  Read More

First-ever flexible ceramic heat shield material

Take note of the name ZircoFlex, because it will most likely, in our not-so-humble opinion, immediately become part of the lexicon and bag of tricks of every automotive, marine, aerospace and industrial manufacturer, fabricator, constructor, inventor and race engineer on the planet. We've previously written about Zircotec’s plasma sprayed ThermoHold coatings, which when applied to the surface of metallic and composite components can reduce surface temperatures by up to 33 percent. Until now, the process has had two major limitations being the need to treat parts directly using 14000ºK plasma sprays and the natural brittleness of ceramic coatings which has limited their use up to rigid substrates. Patent-pending ZircoFlex™ is a flexible ceramic heat shield material that will be available in a roll, offering a low-cost, easy-to-apply solution to the thermal protection of vital engine components. The product is set to revolutionise the use of ceramic materials for heat protection in a wide range of applications.  Read More

Za'abeel Park Observation (ZPO) Tower

From the land of opulence – Dubai - comes another amazing feat of architecture and engineering to add to the emirate’s extravagant skyline. The spiraling tubular design for the Za'abeel Park Observation (ZPO) Tower incorporates roof gardens, extensive solar paneling and geothermal cooling and ventilation in an organically inspired structure topped by three observation deck "petals".  Read More

1.291 mirrored heliostats and a 54 story high tower the World's largest solar power tower ...

Made up of more than 1200 mirrored heliostats surrounding a huge 54 story high tower, the world's largest solar power tower plant is now on-line near Seville in Spain. Developed by Spanish engineering company Abengoa, the PS20 plant generates 20 megawatts of electricity, enough to supply 10,000 homes. Concentrating solar thermal technology has been used in desert areas in Spain and the southwest U.S. for decades and is seeing a resurgence as utilities seek to reduce reliance on fossil fuels.  Read More

Front view of The Thermoteknix VisIR 640 Thermal Imaging Camera.

I'm pretty sure I'm not the target market for high-end thermal imaging cameras like the VisIR 640 from Thermoteknix, but I want one anyway. I want it in the same way that I desperately wanted the X-ray specs advertised on the back of my Iron Man comics when I was 12. In this case, the object of my boyish compulsion features a 640 x 480 infrared sensor, integrated voice recorder, 1.3megapixel color camera, plus an innovative swiveling lens design which provides greater shooting flexibility, and like many examples of ex-military tech, it opens up a huge range of potential applications on civvy street.  Read More

Zircotec's heat resistant Zircon-based ceramic coating

June 4, 2007 We've spoken previously about the amazing heatproofing properties of Zircotec's ceramic thermal coating. Extremely heat resistant, the coating has been put to use by several Formula One teams to move heat out of the engine bays of their race cars. Now it seems this highly effective spray-on coating could have a part to play in emissions reduction and assisting engine manufacturers in meeting the strict Euro 5 emissions standards while contributing to power increases.  Read More
