Engineered or activated water is increasingly taking place in the cleaning industry. It has three major types, which are used for cleaning -- ozone, hypochlorous acid and water electrolysis. Despite the fact that none of these have been recognized as a disinfectant, they are good sanitizers, perfect for cleaning glass and other surfaces. The main thing here is that these activated water solutions help minimize the use of harmful chemicals, thus protecting yours and your children’s health. Many cleaning businesses have adopted the usage of natural, bio detergents, but this technology is on a next level. The fact that cleaning industries can take advantage of the engineered water technology is not a recent finding. The large machines, needed to put into operation this innovative technology, have been around for many years, but customers weren’t happy with their size and price. Recently, technologies have evolved and now even the small, hand-held devices can activate water for cleaning purposes. The rising public awareness of sustainability and global warming issues determines this technology as a great step towards providing eco cleaning services at a very decent price. Еngineered water is obtained through electrolysis, which causes nearly undetectable pH and other changes in its chemical composition. Еlectrolysis is a process which uses electricity to break down water molecules into positively and negatively charged water ions. When you apply water in electrolyzed form to a certain area, the charged ions attach to dirt particles and lift them off the surface. More information about the process you may find in this interesting article. Activated water products and devices are mostly used in educational establishments, retail and healthcare facilities, commercial buildings and owner-occupied properties. Many building service contractors also embraced the idea. What drives the increase in activated water usage is that this technology provides a great value for little money. The usual cleaning chemicals require high costs for production, transportation and storage. In our case, these costs do not exist for the reason that engineered water can be produced on site.

Build your own low-energy, sustainable dwelling using nothing but a mallet and a drill. Four people are needed to assemble the first WikiHouse kit, which is now released and free to download and buy in the UK. Print and build a beautiful timber house, customized to your own needs! And the most important is, people won't have to spend their whole lives paying mortgages. Even me, an employee of this small housekeeping agency, can afford to build a house like this. The WikiHouse Studio, displayed on the pictures here, can be purchased for only £14,500! The basic type of housing can usually be erected by a team of amateurs in 1-2 days. Depending on the project and the design, the other building elements can vary, but it usually takes a total cutting time of 4 weeks and a construct time of 2 weeks. The WikiHouse project is happening thanks to the collaboration of many designers and architects, whose main objective was to create a DIY kit for a timber house which could be constructed by everyone. Various types of buildings can be constructed, like guest or granny houses, tourism cabins, kiosks and small houses which can be grouped around a common facility like a BBQ, a pool or a shared kitchen. Graham Osborne is the principal of Origen Architects in Queensland, and he is the coordinator of this project. He said that the combination of numerous sustainable elements makes this design suited for “the worst case scenario” and he is confident that it will work well no matter the location, weather conditions and climate. The Australian project’s engineering consultant Arup ensures that each WikiHouse meets the building code requirements, as well as both bushfire rating and cyclone rating requirements. Each WikiHouse is made of timber walls and a system of timber cassettes for flooring, OSB cladding and entry beams. Each element of the kit weighs less than 80 kilos, which means that you don’t need a special machinery to lift it, just a few buddies of yours. The houses are designed to sit on stumps and thereby the need for a concrete slab and in-ground fortifications is avoided. The timber cassettes provide a good thermal isolation too. You can download the open source plan from the WikiHouse website, where you can also learn more about their mission, technology, different designs and the annual, locally-held workshops.
