New lasers offer low cost industrial processing
Scientists have developed efficient new fibre optic lasers that deliver short wavelengths for accurate polymer material processing, at incredible strength and low cost. The […]
Combining solar and wind energy
If wind and solar energy can help decrease businesses’ and households’ carbon footprint while reducing energy costs, they also have significant shortcomings. First, […]
The storage of solar energy
Among the key renewable energy technologies, concentrated solar power (CSP) permits the use of relatively cheap thermal energy storage (TES) […]
Aluminothermic welding
Aluminothermic welding is mainly used for the welding of railway tracks. It is a procedure for autogenous welding by fusion […]
The new EastMed pipeline
The Eastern Mediterranean (EastMed) pipeline will be designed to transport up to 15 billion cubic meters from the recently discovered […]
The gas turbine spool
The gas turbine (not to be confused with the homonymous machine), is an internal combustion engine used to transform by means […]
Evaporating water will power cars
A Columbia team has developed a miniature car that harnesses the power of evaporation to drive itself forward, as well as an evaporation-driven generator that powers a flashing LED lamp.
Solar and clean energy
In recent years there has been a revolution in the field of new photovoltaic materials. Among these the hybrid organic / inorganic ‘perovskites’ are able to convert 20% of solar energy into electrical energy.
Use of the fibers for the transport of heat
A recent study by the Institute for polymers, composites and biomaterials of the National Research Council (CNR) in Pozzuoli has brought out a new fiber properties, of great practical importance: the fibers not only act as reinforcing materials, but also have the function of transporting heat quickly along the longitudinal axis.
An alternative configuration to govern the plasma
The plasma is confined by means of a toroidal configuration of magnetic fields. The configuration used, on which is based […]
