“PowerTextiles” Next Generation Photo Voltaic’s

Selkirk, 27 November 2013

 

Dr. Robert Mather and Professor John Wilson share a moment to show off their Solar PV Textile they call PowerTextiles. After many years in the laboratory these two eminent Scottish scientists successfully integrated PV into a polyester fabric. PowerTextiles is one conductive polymer layer integrated with conductive and semi conductive layers on polyester fabric.   Why are PowerTextiles the future of the Photo Voltaic Industry? PowerTextiles are more flexible than any other existing solar panel technology, firstly the surface of the fabric is not flat like traditional PV materials it means from the offset they can potentially harvest more sunshine than lets say ultra flat silicon or even flexible thin film cells. All solar harvesting averages but a few hours a day at best, unlike regular panels once the system is done for the day it can be rolled up, or retracted to become unobtrusive. Solar textiles are also temporary structures, potentially needing no planning permission. Unlike solar panels which are obtrusive PowerTextiles life cycle is truly extended as they can be placed out of harms way when not in use. Continue reading

Buildings Don’t Need to Breathe Only People Do!

Campus OneWarsaw 14 February, 2013

Commercial buildings which do not achieve Air Tightness often waste 20% to 40% of the total energy that they consume. When the building envelope is not tight energy is simply lost to the outside. Defective roof lights, smoke hatches and curtain walls, a result of poor design, defective construction, or incomplete maintenance is widespread. “We waste so much energy for no good reason” says SOLIDEA’s Steve Walker  “Air Tightness is the big ticket cost in retail, commercial offices and hotels, and it has nothing to do with the level of Insulation installed”

What is Air-Tightness?

The level of Air Tightness in a building is measured as Air Permeability it is the measurement of the volume of air which leaks through the building envelope per hour per m² of building envelope at 50 Pascals Differential Pressure. Air Permeability is then expressed as a rate for example 3 m³/h. m² at 50 PA which is much better than 7 m³/h. m² at 50 PA. We can test Air Tightness on site and we can easily quantify the energy losses simply by measuring Air Permeability Continue reading

Great Mines Think Alike

Santiago, July 23 2012

The remote mining industry holds huge potential for the renewable energy and renewable water industry who fondly refer to their art as “Watergy”. SOLIDEA’s Watergy is an holistic modern economic approach to the combined energy, water and waste consumption of any installation an art that saves mine owners and operators money.

Good Watergy practice for remote mining project considers the full life cycle impact of the fuel, energy, water and waste design and both on and off the site. Watergy is a hot topic in the mining industry these days as public opinion, natural conservation and meeting tough new environmental requirements impacts project certainty even in the remotest locations.
