More about solar heating: a wealth of energy from the desert
More about solar heating: a wealth of energy from the desert Interest in the new solar energy frontier, thermodynamic solar energy, is constantly growing and is now dominating the scene. It’s a technology that has already been extensively tested, from California to Spain, and even Italy, where a small pilot power plant is being started in Sicily. But now a megaproject seems to be at the starting line, a project which will create dozens of power plants using desert areas from Morocco to Jordan. This is a long-term project with a total investment of over 400 billion euros, and it will be able to guarantee, after covering the hosting countries, a supply to Europe of 15% of its energy demand at a final cost of less than 5 cents of a euro per kilowatt-hour. Cheaper than coal and nuclear energy. The fact that most of the answers to our growing energy needs can be found in solar energy seems to be beyond question, especially since even a genius like Carlo Rubbia, winner of a Nobel Prize for physics and author of the project developed at the Enea Center, believes that: "Just a minimal part of the Sahara would be enough, a 210 km by 210 km square: the Sun radiates an average of 15 terawatts of energy on this area every year, equivalent to the amount our entire civilization consumes".
The new Butylver colorations for designers and architects
The new Butylver colorations for designers and architects The Fenzi group has expanded its range of sealants. In order to meet the needs of the trade, not only on a technical and environmentally friendly level but also in terms of sophisticated appearance, Butylver is now available in both light and dark grey.
This innovative coloration makes the Butylver sealant compatible with the aesthetic needs of architects and designers alike, providing a solvent-free one-component sealant ideal for internal insulation (first barrier) of insulating glass units, universally recognized for its minimum water vapor and gas permeability, high aging resistance and outstanding adhesive properties on glass, aluminum, steel and stainless steel.
It’s an additional advancement for the use of Butylver in continuous façades. In fact, the edge sealing in this type of application is visible in two shades of grey, matching nicely with the coloration of the structural silicones used for the second sealing. This produces a homogeneous visual effect. On the other hand, if the edge sealing is covered by the frame as in traditional insulating glass units, the new Butylver coloration has a diametrically opposite effect. The grey color, in fact, highlights and differentiates the first barrier sealing from the second sealing, facilitating quality control and dimensional checks of the sealing.
