Experimental

Researchers at Queensland University of Technology have developed a recyclable and renewable barrier coating for paper and cardboard. Historically industrial coatings have included wax or thin plastic films such as polyethylene or polypropylene. However there is an inherent problem with these conventional coatings in that recycling is often very difficult. The novel QUT approach utilises a unique lignin-based formulation to facilitate the formation of a thin film that acts as a barrier to moisture.

The technology is a hybrid process that utilizes both sulfur-tolerant and high power density planar solid fuel cell (PSOFC) stacks to produce power at a higher efficiency. The sulfurtolerant PSOFC stack uses anode materials that selectively convert Hydrogen Sulphide (H2S) present in fuel streams to non-poisoning sulfur compounds. The remaining gas balances which are nearly free of H2S are used as fuel inlet to the conventional PSOFC stack.

Background: This technology provides a low cost low maintenance solution for generating electricity from ocean waves. Its unique magnetic coupling system isolates all mechanical components from the harsh marine environment making it ideal for powering sensor arrays communication nodes or other applications within the coastal zone. The technology will help to break down multiple barriers (power and communication) and accelerate development of coastal sensor networks across multiple sectors (environment security commerce etc.) growing the market in the process.

A device powered by solar panels to charge phones.

Excarvation of earth pan for harvesting and storing rain water.

This is a lamp made up of an outer layer polished Clay liner a cement and clay middle mortar and a green metal casing out. The clay liner has a rocket design making it easier for fire to burn under pressure. The polish liner radiates back the heat centralising it in the middle thus conserving the heat.

Three cooking pots with copper price wound on the pot which passes the heat to the water through it.

The device and method for the depressurization levitation of wastewater sludge. A sludge treatment method and a sludge treatment system which efficiently and reliably increase the concentration of sludge raise the efficiency of methane fermentation of highly concentrated sludge and use energy effectively and efficiently.

Use of briquettes and wood fuel to conserve energy.

Optimum solar utilization and use of affordable solar energy materials. Alternative materials which are cheaper are used in solar energy production.
