solar heated swimming pool doubles as awning

Toasty Autumn swimming!

Imagine taking a dip in your outdoor swimming pool in late October, even November as the ground hardens and the frost thickens. The steam is coming off of your heated pool, and its not costing you a cent – apart from considerable installation costs that is.

There are some design factors to be considered, including proper sizing and location. But there are many web sites to help you, as well as the off-grid technical forum for advice. It’s not imperative to have your solar pool heater configured and installed by experts. (more…)

Tips for harvesting rainwater
by TECHSTAR on JULY 28, 2013 - 4 Comments in WATER

Umbrella can be used for rainwater harvesting

Any surface will do

Many cities and states encourage rainwater harvesting, yet few homes and commercial buildings have implemented it.

Excuses range from the cost of construction to lack of knowledge. Yet individuals who have incorporated such systems say that integrating water harvesting reduces costs over the long run.

“I have not used Utility water since 1994 in my home.” said A R Shivakumar. “With planning, rain water harvesting does not have to be expensive and space consuming.” Here are his tips:

TANK IT UP

Multiple rainwater tanks can be built depending on the flow of water. For instance, at Shivakumar’s home there is a 4500-litre rooftop tank. The excess water from this tank is allowed to run down rainwater pipes to a 25,000 litre sump built under the portico. If these two tanks fill up, then the extra water is allowed to seep into the ground. (more…)

Six things you should know about rainwater harvesting in the desert

Water harvesting in Tucson,AZ

Makes you parched just to look at it

TUCSON AZ – New techniques and revival of old skills can make a little water go a long way, even here in the Catalina foothills.

1. The secret to urban water harvesting is using the many impermeable surfaces that surround us: roofs, streets, sidewalks and driveways. The runoff from those surfaces amounts to a huge amount, if properly collected and used for irrigation. In rural situations, create as many hard surfaces as you can.
2. Good collection techniques can triple the amount of water that falls, so for example, the patch of garden that now needs irrigation would get about 12 inches a year. That’s still pretty dry, but it does just lift that patch out of a “desert” definition. Diverting rainfall from your rooftop and driveways can provide quite a bit of water for irrigation. (more…)

Food storage ideas…

prepping
Preppers are always trying to get everyone else to at least begin stocking up on some short and long term food storage, honestly the biggest reason is because the more of you who prep, the fewer of you we have to worry about showing up on our doorsteps if/when the SHTF… of course we ALL hope that none of this is ever needed, I wouldn’t be a bit upset if 20, 30, or more years from now I get a big “I told you so…” from those who never prep… but the reality is, it’s better to have it and not need it than to need it and not have it.

So with that said, here are a few videos showing the sorts of things that are relatively inexpensive and easy to stock up on. Things like protein, it’s something we all need in our diet, the good thing about these sources of protein is they don’t require refrigeration and most of them are relatively easy to open, they have pop-tabs or come in pouches that don’t require anything but your fingers to open.

Patent Application submitted for off-grid Water Condenser

Archetypal water condenser

Archetypal water condenser

Canadian firm Freedom Water Company Ltd. combine caqre for humanity with technical skill in this patent application submitted for Approval. Here is an exerpt from their document:

“At any given moment the earth’s atmosphere contains 326 million cubic miles of water and of this, 97% is saltwater and only 3% is fresh water. Of the 3% that is fresh water, 70% is frozen in Antarctica and of the remaining 30% only 0.7% is found in liquid form. Atmospheric air contains 0.16% of this 0.7% or 4,000 cubic miles of water which is 8 times the amount of water found in all the rivers of the world. Of the remaining 0.7%, 0.16% is found in the atmosphere; 0.8% is found in soil moisture; 1.4% is found in lakes; and 97.5% is found in groundwater.

“Nature maintains this ratio by accelerating or retarding the rates of evaporation and condensation, irrespective of the activities of man. Such evaporation and condensation is the means of regenerating wholesome water for all forms of life on earth. (more…)

Price of harvesting rain in South Africa
by TECHSTAR on JUNE 15, 2013 - 1 Comment in WATER

The price of water is rising sharply in the ritzy yet dangerous countryside around East London. Even the rich, old, white landowners are going into rainwater harvesting to protect themselves from municipal price increases.

Land surveyor Neil Henderson is doing it at his Nahoon Mouth home – collecting water off his roof, storing it in tanks and he believes it is the way to go.

He recently had eight 5 000 liter tanks installed. He says in 2007 each tank would have cost 2785 Rand (about $276 US), a 5% a year increase from 2004, and at today’s R3369 would have amounted to 10% a year escalation. (more…)

Thatcher’s Legacy – time to Nationalize the Utilities

Asset-strippers became media heroes

Asset-strippers became media heroes

Margaret Thatcher privatised Britain’s power, water and rail network, handing huge profits to the private sector, at the expense of ordinary homeowners. Perhaps the best way to mark her death yesterday would be to renationalize the Utilities. Bolivia nationalised its domestic energy resources a few years ago. A shrewd move, at a time when owners of natural resources hold the best cards.

Maggie Thatcher’s greatest legacy was (together with US President Ronald Reagan) initiating the free market economics that have led directly to the bonus culture and gaping income inequality.

The era of “greed is good” capitalism went global, a fitting tribute to this extraordinary politician. Britain’s first and only female Prime Minister, she set the template for a massive transfer of public money into private hands.

The privatization of the state owned energy industry took a lumbering inefficient national power grid and turned it into a lumbering, inefficient and eye-wateringly expensive Corporate national power grid, where nearly 20% of households are officially in fuel poverty. (more…)
