Zero Mass Water

A regular supply of drinking water is the holy grail for off-grid living.

If you can get a bare minimum of water and heating of some sort, you can live anywhere. but you would be surprised how many spots that are otherwise ideal do not have an easy water supply – either due to the topography, or local laws.

Now a US startup has come up with a solution that actually works! And its for sale now. At a reasonable price

Zero Mass Water, based in Scottsdale, Arizona, produces $2,000 “hydropanels” that the company claims can capture water vapor from air. One panel can make up to five liters a day, and two of them together could produce enough for a household’s daily drinking and cooking says the company. In theory, someone could drive out to the desert, and live off the grid with water to spare.

A journalist from Wired checked out the gadget – basically a solar panel bolted on to a special membrane that extracts the water vapour, filters it and pumps out 12 liters per day – it works out about $50 per month if you spread it over 10 years, which is pricey but you can take it anywhere and what you get is pure water, untainted by any Utility company, when and where you need it to be.

You have to accept that Zero Mass is just the name of the product. The company’s founder, Cody Friesen, a professor of materials science at Arizona State University says the units weigh 275 pounds (a long way from zero then) and are intended for yards and rooftops, rather than mobile living.
Hydrophilic membranes trap water vapor from air that’s blown across them by a solar-powered fan. The vapor-turned-water then drops and pools and flows through a series of mineral cartridges to make it more drinkable. Because both the landscape and the water vapor in the air are changing all the time, the panels connect to HQ back in Scottsdale via a mesh network, and Zero Mass Water staffers upload predictive algorithms that adjust fan speeds and maximize energy efficiency.

How the Hydropanel Works

The panel contains absorbent material that pulls moisture from the air.

Solar heat causes the moisture to form drops.

The drops collect in a reservoir at the panel’s base.

A pump draws water out of the reservoir and into a tap.

Rainwater Harvesting: Global Storming – Bring it on

Water harvestingInstalling a Rainwater Harvesting System (RHS) could be a major step in achieving your ideal, eco-friendly home. You could be collecting your own water through the beauty of nature rather than seeing the bills pile up on the doormat from the Utility Company. By installing a run-off system from your roof that leads to a storage area, pumps and purifiers, rainwater can be used across your home.
Even if you are already connected to the water supply, there are advantages to harvesting rainwater. If you are on a meter, your water bill will be reduced as the collected water can be put to use for non-drinking purposes such as showers, baths, flushing toilets, washing dishes. Drinking water is not easily renewable and if you wish to use your collected water for things that don’t require purification, harvesting is cost effective and requires little maintenance. It is also beneficial in terms of reducing wastage.
If you are cultivating your own crops and living off your plot of land, the collected water can be funnelled into an irrigation system. On an environmental level, the collection of rainwater will vastly improve the levels of groundwater. With a rise in population, groundwater levels have decreased and therefore increased the strife in parts of the world where water is scarce. Rainwater harvesting also reduces the level of surface water and lessens the chance of flooding, soil erosion and river contamination brought about by rainwater running through pesticides and other agricultural chemicals.

The disadvantages of rainwater harvesting are two-fold. Firstly, the initial cost of installing a storage system, purification methods and pumping can, according to YouGen, cost between $3000-$5000 (£2000-£3000 )and then running the pump will cost 5-10c a week. However you can now have your RHS plumbed straight into your existing piping and according to the Rainwater Harvesting Association can reduce your water consumption by as much as 40%. The use of a cistern to obtain drinking water in a city can be a tricky business. Shingled roofs, rather than clay or metal are less clean and liable to allow pollution to seep into the water. A pre-filtering system would have to be set up on the shingled roof prior to deposition in the tank to achieve drinkable water.

With water remaining in storage for a considerable degree of time, it is prone to stagnation, algal blooms and rodents spreading water-borne disease. Your harvesting system therefore has to be regularly maintained. Then of course, you are at the mercy of the clouds. Rainfall can be unpredictable and your levels of water will be affected by your geographical location.

The legal and red tape processes one has go through in order to begin to harvest your own water vary wildly. In 2012 a RHS case went viral when 64 year old Gary Harrington from Oregon was sentenced to 30 days in prison for illegal collection of …

“I paid Sydney Water $800 a year — now I get it for free”

Living in a city it can seem hard to kick free from the grid, but in Sydney Australia, Newtown resident Kylie Ahern will soon become the latest environmentalist to live completely off the grid.
“I am currently getting all my water from a series of tanks – one is buried in the backyard and the others are above ground,” Ms Ahern said.“I used to pay $800 a year to Sydney Water, now I get it all for free from my roof.
“I also have a stormwater absorption pit so all the water coming off the roof goes straight into the tanks and then into the pit.

“I am putting solar panels up and installing batteries and my aim is to disconnect from the electricity grid.

“I am in the process of looking for the most energy efficient appliances and I am cutting off my gas as I will be using an electric induction cooktop.

“The coal seam gas situation in this country has been really upsetting, therefore I want to make sure I am not contributing to the problem.

“We are lulled into thinking we need to pay for these services like water and electricity that we can get for free. Sewerage and plumbing is my next task as I can’t get the tanks onto my property just yet but they are something I am definitely aiming for.

“I am expecting all the work to be completed by early next year.” The Newtown resident shared her disdain at the inaction of politicians charged with reducing global emissions and encouraged other like-minded conservationists to follow in her footsteps.

“I have watched politicians over the years do very little to protect our environment and fail to do anything meaningful around reducing our emissions, so I decided that I had to do more,” Ms Ahern said.

“I think most of us want to do more to protect the environment but it’s knowing where to start that’s the challenge.“You don’t have to do a full renovation of your home; you can do little things like buy energy-efficient appliances or use a diverter so excess rainwater goes into your garden.”

The process of creating a self-sustaining property may seem like a daunting or impossible task to some, Ms Ahern insists it is a relatively streamlined process, if you have the right help.

Ms Ahern, recruited the assistance of Chippendale’s Michael Mobbs, who famously took his home off the grid in March, hopes to achieve the same results with her two-bedroom worker’s cottage by early next year.

Utilities enter the Death Spiral

offthegridnews,eric valli, utilitiesElectricity and water rates are set to rise sharply because so many households and business are now generating their own power and managing their own water supply. The Utility company fixed costs are not going to change however many people close their accounts and go it alone. So those costs have to be paid by a shrinking pool of consumers.
Utility executives even have a name for the nightmare scenario which more and more solar panels, or boreholes or wind turbines could create – they call it the “death spiral.”They fear solar’s rapid spread across homes and businesses, combined with the increasing efficiency of modern buildings and appliances, could slowly erode the utilities’ ability to generate profits.
