District heating ‘wasting millions by skimping on insulation’

The developers and operators of district heating projects are wasting millions of pounds by skimping on pipe insulation. That’s according to a manufacturer of pre-insulated pipe systems, CPV, which said the standard for pipe insulation – the EN 253 – allows for three different thicknesses of foam.

Solar cell breaks world record for efficiency

The world record for solar cell efficiency has apparently been broken after a team of researchers created a cell (pictured) that can convert 44.7% of the energy in sunlight to electricity, by stacking materials that absorb different wavelengths of light on top of each other. The development was jointly announced by the Fraunhofer Institute for […]
