Experimental Tech in Desert Village

An off-grid desert village in Kibbutz Ketura, Israel is being used as a platform for tech companies and entrepreneurs to develop innovative off-grid technologies. The village was set up in 2014 via a collaboration between the Arava Institute for Environmental Studies and Eilat-Eilot Renewable Energy Initiative. The project is aimed at developing off-grid solutions for undeveloped areas, encouraging experimentation. It is the key step between development and implementation in areas where whole communities have no grid access.

There are four key areas for off-grid living which are currently being developed and worked on in the village.

Desert Village Building:

There are three types of structure in the village, based on existing building types within in off-grid communities. The rural structure is based on a traditional design and has a thatched roof to help with ventilation, but lacks natural light. Therefore, to adapt it, the village has added windows to the buildings to provide natural light for reading and other activities, as well as providing more ventilation.

The urban structure is based on a design most commonly seen in urban slums. The modifications to this design are the double roof structure and wall insulation. The first roof layer is made of palm leaves for ventilation purposes and the second consists of metal for protection against the rain. Plywood walls have insulator material like sheep wool within the wall to keep thermal balance in the building. The structure is mainly based on plywood which is low priced and the design is simple to construct.

Finally, the earthbag dome design was first developed in the 1980s, using soil sacks to construct huts. The bags of soil provide a rigid, stable structure with a balance of temperature. There is no need for deep foundations or a separate roof structure, due to the dome shape. These buildings are rapid to construct, simple and cheap.

Energy:

The desert village has some different energy technologies within its boundaries. The Kalipack solar suitcase can produce energy from three sources – electricity, a vehicle or solar power. Storage takes the form of a lithium ion battery and can power a small refrigerator, laptop or lighting, amongst other things. The village also has a small domestic biogas system which has efficient waste disposal whilst producing methane gas for cooking, water heating and home lighting.

LuminAID have introduced some chargeable and easy to use solar lighting. But GravityLights have also been developed at the village. These work by combining kinetic energy with potential energy. A weight of some sort is elevated and connected to a pulley system which powers a generator. The result is a light which is five times brighter than a kerosene lamp. Surveys with families using the lights have been very positive so far.

Water:

Clearly something that is very important in every community is clean water. The desert village has a solar water distillation system developed …

EcoSolarCool new Solar Refrigeration

 

EcoSolarCool have kick-started 2017 with the release of two new Solar Refrigeration models. The new additions to the upright product line aim to minimise the daily power consumption of cooling appliances. Refrigerators are one of the most energy consuming appliances in the home, accounting for up to 25% of household energy cost. EcoSolarCool want to change this, “providing constant, reliable and energy efficient cooling at great value.”

Two New Models

Both of EcoSolarCool’s new models are approved by UL250 and CSA to US and Canadian standards. These are the only solar refrigerators in the world to hold this approval. Plus this is for the whole unit and not just the compressor. Both models have the most up to date and advanced Danfoss DC compressor and are manufactured in Europe. The power consumption for the models is also at a record low for the solar/DC appliances industry at 201 kWh per annum! This is also amongst the lowest in the AC refrigeration appliances market.

The ESCR260GE Metallic Grey model has a total capacity of 260 litres (9.2 cubic feet). The refrigeration compartment is larger in comparison to the freezer compartment at 235 litres (8.3 cubic feet) to 25 litres (0.9 cubic feet). The freezer is located at the top of the unit and the refrigeration compartment at the bottom. This model weighs in at 121.3 lb (55kg) and is 23.7 x 25.2 x 57.1 inches.

The ESCR355GE Stainless Steel model has a total capacity of 354 litres (12.5 cubic feet). The larger refrigeration compartment (258 litres/9.1 cubic feet) is located at the top of the unit, and the freezer compartment (96 litres/3.4 cubic feet) at the bottom. This model weighs in at 163.2 lb (74kg) and is 23.7 x 25.2 x 78.8 inches in size.

Features of Both

Both models have adjustable internal temperatures and reversible doors. The temperature range for the cooling compartment is between 0°C/32°F to 10°C/50°F. Whereas, the freezing compartment temperature can reach as low as -18°C/-0.4°F. For operation, both models need a solar panel, a 12 volt AGM, lithium or deep cycle battery and a 15 amp 12/24 volt solar charge controller. The battery ensures the refrigerator will continue running through the night and on not so sunny days. Whereas, the solar charge controller regulates the electric charge from the batteries and the solar panel(s). To find out how many solar panels/batteries needed to run your solar refrigeration appliance, check out EcoSolarCool’s blog post.

The refrigerators are perfect for a wide variety of situations from RVs, to cabins to on and off-grid homes.

Both refrigerator models can be bought from a local dealer or the Solar Power estore. Prices advertised on the EcoSolarCool website are $1,299.00 for the smaller Metallic Grey model and $1,650.00 for the larger Stainless Steel model.

Be Our Guest – Food Preserving Part 2

In Part I, I covered canning and smoking as food preservation methods. This article takes a look at refrigeration and dehydration.

Freezing and refrigeration is the easy way to preserve food compared to some other methods. The only problem is, once frozen or cooled it has to stay that way until consumption.

Before the wonders of electricity and modern technology, how did people do this?

On farms and in small villages it was common to have a spring house which would provide natural refrigeration. A stone building with troughs dug into the ground on which the house stood would be built over a natural spring. Water from the spring would flow through the troughs and jugs of milk or other produce could be placed in the channels. These would then be kept cool as the water flowed around them. Ledges and hooks would also be provided in the spring house, to hang meat and vegetables in a cooler environment.

If the house wasn’t built over a natural spring, water could be redirected from a nearby creek. Initially some spring houses were made of wood, however this was prone to rotting. Stone therefore is the better material, not only does it hold the cold better but it won’t decompose or decay with time.

Fancy building your own spring house? You can find out more at Bright Hub.

Another option which was used before electricity and still used today is root cellars.

These underground rooms stay cool in the summer but above freezing in the winter – perfect for fruits, vegetables and canned goods. The cool temperatures prevent bacterial growth and the humidity prevents withering. Ideally the cellar will have temperatures between 30 and 40 degrees Fahrenheit, have low levels of sunshine, good insulation from materials such as straw or soil and be easily accessible.

Root cellars come in a variety of forms from walk in rooms to putting trash cans in the ground to create a “mini” cellar. If you’re on a tight budget, take a look at this video by the Walden Effect, who made a root cellar out of an old refrigerator.

Speaking of refrigerators, if you want to be a bit more tech-centric, then there are various options for off-grid cold food storage.

Propane fridges have been a staple for many RV owners and in off-grid homes. Some models can run off propane, DC or AC, making them more flexible. Although these appliances are good for keeping food cold and frozen with ample storage, they do require some maintenance and if they break down can be expensive to repair. Not only this, propane may be unavailable or very expensive to get hold of in certain areas and some propane fridge models can be extremely “fuel hungry” – not exactly the most economical option. There is also an initial investment of over $1,000. Take the Dometic

Be Our Guest: Food Preservation Part I

 

Charcutier Sean Cannon is opening his first restaurant, Nape, in London this month. Born and bred in Norfolk, Sean told the Guardian how growing up in a self-sustaining community influenced his cooking. His best kept secret – preserving.

“Whether it’s killing an animal and having lots of fresh meat, or early summer and everything is ripe, knowing what to do with a glut is key.” Cannon said.

If you live off-grid you’ll know that preserving food for future use is essential. Not only does it provide food security, but also allows you to taste sweet summer berries in the winter. By doing this age old tradition, it also stops more modern thoughts and concerns of “what is actually in my food?” If you do the preparing and the preservation, you know exactly what has gone into the food you will be eating.

There are many ways to preserve food including canning, freezing, dehydrating and smoking.

Canning is a valuable and low-tech way to preserve food. There are two main methods for this, either water bath canning or pressure canning. It is worth noting that water bath canning should only be done for acidic fruits, such as berries and apples. If canning other produce such as meats and vegetables, pressure canning should be used; otherwise there is a high risk of food poisoning.

The basic process is to heat water in your canner (or large pan if water bath canning). This should not be filled to the top; 3-5 inches should be left for your jars of food. Jars should have lids secured and be placed carefully into the canner, being careful not to knock other jars, as they could crack or break under the high temperatures. The jars should be immersed in the canner with the water just covering the lids. The canner lid should be locked in place if pressure canning and the jars left for as long as needed according to the recipe. After the required time, the canner should be allowed to depressurise if using a pressure canner, before the jars are removed. Heat protection and necessary precautions should be taken to ensure you do not burn yourself. The jars should then be left to cool and seal for a minimum of 12 but ideally 24 hours. The sound of popping and pinging will mark your canning success!

Canning is so popular because of the wide variety of foods that can be preserved this way and the length of time they will remain edible for. Plus there’s no worry of keeping food frozen or cool!

Canning does however come with an initial start-up cost. If you’re only looking to preserve fruits and jams, then water bath canning in a large pan is of course an economical way to go. However, if you’re looking to preserve a wider variety of foods which includes meat and vegetables, …

Tech 101: All about Batteries

New to off-grid living? Thinking about going off-grid? Have years of experience? Bet you’ve thought about batteries.

Having a back-up store of energy for those cloudy still days, when your renewable energy system isn’t exactly on top form, is a grand idea. But navigating through the types of battery and which is most suitable can seem like a bit of a minefield. Actually, quite a huge minefield.

Way back when…

Initially when off-grid living took off, people turned to car batteries for their storage needs. However, being designed to give out a large current in a short burst, they couldn’t take the strain of being used for longer periods. This usually ended in a burnt out battery after only a year or two of use (if you were very lucky). but a few folk DID get lucky and begged or bought old Fork-lift truck batteries – and found them to be ideal.

Enter Deep-cycle Lead Acid batteries

Designed for a steady current output over long periods and with several hundred discharge- recharge cycles over its lifetime,  these are perfect for partnering with renewable energy.

There are several different types of lead acid batteries which can be used off-grid. The most commonly used in conjunction with solar and wind power are: golf cart batteries, L16 batteries and industrial batteries. All of these are flooded with electrolyte which evaporates during charging, meaning maintenance is required. This extends to checking electrolyte level a minimum of once per month and topping up with distilled water when needed.

Golf cart batteries are good for those completely new to off-grid living, who have a small scale renewables system. The upfront cost of these units is low, meaning if first timers make any mistakes and ruin a battery, the financial loss is minimized. Lasting 4-5 years, these batteries have a reasonable lifespan. They are durable, and can withstand undercharging without too much impact on their storage capacity – reducing the chance you will be scratching our head and saying: “hmm this battery doesn’t seem to hold its charge as long as it used to”.

Batteries can be scaled up in a bank, depending on the amount of storage required. A set of four 6 volt, 225 amp batteries in sequence can hold 4kWh, increase this number and you could potentially have a bank capable of storing up to 16kWh. With prices starting below $100 for one unit, this is by far the most economical option for those with small scale electricity needs.

 

If you want to step it up from a golf cart battery, then L16 batteries may be the way to go. Even though the units are twice as heavy at 120lbs! They can power small to medium set ups and have a lifespan of up to 8 years. There are also 2 volt models available, allowing for greater storage capacity if a …

Regenerating the Eco-village

Self-sustaining communities that can talk to each other; sounds like something from the future doesn’t it? But Regen Villages is making this a reality – right now. The first Regen eco-village has begun building works in Almere, 25 minutes from Amsterdam, the Netherlands. The 15,500m² project will house 100 families and aims to be completed by 2018.

But what is a Regen Village?

Founded by James Ehrlich, a senior technologist at Stanford University, in 2015, Regen Villages has a holistic approach. A regenerative system combining new technology and renewable energy powered homes, with organic food production right on the doorstep.

The houses vary in size and are built inside a greenhouse “envelope”, with some even having terraces. Each home has a built in water collection system, solar panels and are passively heated. The community has a seasonal garden, biogas facility and aquaponics amongst other things.

The base of the villages is that the output of one system is the input to another. Waste from the homes is sorted into different categories. Bio-waste is used in the Biogas facility, whilst compost is used as food for livestock and small flies. The flies are fed to fish and the waste from both them and the livestock fertilises the seasonal gardens. The plants in the aquaponics facility and seasonal gardens produce fruit and vegetables for food, whilst the livestock and fish provide a source of protein. Rainwater is collected and stored at the houses and water produced at the biogas facility is also stored. Grey water is separated and used to irrigate the seasonal garden, whereas clean water is put into the aquaponics. Solar cells provide the energy for homes and also to the “smart grid” which can be used for charging electric cars.

Regen Villages, who are partnered with Danish architects EFFEKT, have been termed the “Tesla of ecovillages” paving the way for new innovative developments. Plans include villages being linked up to the cloud and being able to communicate with each other through the internet. In this way communities are self-reliant and off-grid but can still learn from each other.

What about the future?

At a conference held at Sliperiet, Umeå University, Sweden James Ehrlich spoke of the future for Regen Villages. After the completion of the Almere pilot, EU funding of a proposed 300 million euros (approximately $319 million) will enable projects in Sweden, Norway, Denmark and Germany to go ahead. These are aimed to be carried out during 2018-2022. Sights are then set on developments across Malaysia, Saudi Arabia, India, China and parts of the US, with government investments. As Ehrlich outlined, by targeting a challenging cold environment first, Regen Villages can be adapted to suit different climatic needs.

Off-grid sustainable greenhouse communities are not at all futuristic and Ehrlich is keen to make them a reality.

Off-Grid School Gets Top Marks

A cash-strapped performing arts school has traded a year’s worth of waste for 30 desks.

The off-grid school collected its community’s recycling, as well as its own, and bartered this for the recycled desks.

Set up in 2005, the grid wasn’t working for 65 pupil school Chistlehurst, Pietermaritzburg, KwaZulu-Natal, South Africa so they devised a plan. Stick with their eco-friendly ethos and remain off the grid.  Unlike an on-grid school, there is no sprinkler system, no heating in the winter and strictly no technology in the classroom. So things are done a little differently, students carry buckets of water from the rain water tanks to the gardens and huddle by a bonfire to keep warm on cold mornings.

“Our kids have had to learn how to get along without certain ‘luxuries’, which is something they take a little time to adjust to, but end up loving the ‘quietness’ of it all,” said Jacyn Fanner, Headteacher.

When they moved into their current building, there were no roofs, doors or windows. Let alone functioning taps and toilets! But after a lot of hard work, the school reached their off-grid goal. Rain water tanks fill the toilet cisterns, solar lighting illuminates the classrooms and batteries, gas and a small generator provide extra energy.

The school is also home to a frog pond, vegetable garden and a recycling village with 12 bins for different materials. This allows the school to recycle a range of materials from mixed paper and cans to plastic and styrofoam. The majority of cleaning products and equipment are sourced from the local community and are as eco-friendly as possible.

The school partnered up with the Wildlands Conservancy Trust 6 years ago, through their desire to recycle. The NGO, which operates in 6 provinces, provided the school with the recycling bins which are filled every week – even during the holidays!

Students have taken their eco-friendly lessons from school to home, encouraging their families to reduce re-use and recycle. So now recycling from the local community is brought to the school for collection. Each year the school get a rebate from Wildlands for the recycling they collect. However at the end of 2016 this rebate was traded for the eco-desks. The staff and students are very pleased with how they look in their eco-school setting and Headteacher Jacyn Fanner wants to see them fill all of the classrooms in time.

So what’s next?

“We have so many ideas and plans – which include a fully solar powered media centre – and we are so excited for what the future holds for Chistlehurst,” Jacyn Fanner said.

The desks are made from 100% previously unrecycled materials, are hard wearing and can be used both indoors and outdoors. Chistlehurst are so pleased with the outcome, they are encouraging other schools to get involved with green initiatives such as Sustainable Schools and Recycling for …

Try Out Ecovillage Life

Want to test out living off-grid but don’t want to do it alone? If you have $6000 to spare you can by taking part in the Permaculture and Ecovillage Immersion Experience with the School of Integrated Living (SOIL).

This two month residency running from June 10th to August 11th is less of a course and more of an eco-cultural learning experience.

Located in the ecovillage Earthaven near Asheville, North Carolina, you’ll gain new skills on a wide curriculum. From learning about ecological farming to efficient irrigation techniques and eco-spirituality, there is something for everyone. Most days will begin with a meditation session before getting stuck into the day. There will be unstructured time, but most weeks will cover approximately 50 hours of learning. A Permaculture Design Certification course is also included, which will take place in mid-June.

Earthaven was founded in 1994 and sits in 329 acres of land. A completely off-grid community powered with solar panels and two small hydropower stations. The buildings are made of environmentally friendly materials, usually lumber, with metal roofs for water catchment. Most are passively solar heated and propane burners help to keep them warm during colder months. The huts and residences have either individual or shared solar systems which supply their electricity. Batteries and generators are also charged by the micro hydropower stations for back up supplies. Although most of the residents get around by foot or bike, three solar powered golf carts can also be used.

Course participants will camp on site, with the majority of spots being for two person tents. A tarp covered kitchen with propane burners and a composting toilet are all available for use. Food is also included and most is sourced from the local environment and small farms in the village.

The cost of the course is $6,800 including tuition, food, camping, field trips and the permaculture design certificate. There is a $400 discount if booked before February 10th.

If you don’t want to spend two months at Earthaven but would still like to visit – you can! Workshops and tours are open to the public. Camping is also offered for $15 per adult per night, or $20 for two adults sharing a tent. The camping season runs from March 31st to November 5th.

Hut, Scotland, Building Regulations, Bothies, Off-Grid

Return of the Scottish Hut

If you fancy buying an inexpensive off-grid getaway in Europe – try Scotland.

The government announced changes to their building regulations early this year. This will include huts of up to 30m² becoming exempt from regulations, specifically aimed at making it simple for people to achieve a life off the grid.

In a few months, you could be gazing out from a building like the one in the picture for less than $25,000 inclusive.

Scotland has a strong hutting culture dating back to the early 20th century; it was only 60 years ago that this began to dwindle. The largest remaining hut community in Carbeth, near Glasgow, managed to weather this decline. The community bought the land on which their 140 huts stand in 2013. But now resurgence is happening, thanks mainly to the campaign A Thousand Huts championed by the environment organisation Reforesting Scotland.

This organisation recognises the benefits of hut life, offering a retreat for rest, recreation, enjoying nature and making memories with family. Alongside use as a base for outdoor activities, huts contribute to sustainable development and encourage learning new skills. Reforesting Scotland have been lobbying for changes to the law for some time and are keen to encourage more people to adopt the hut lifestyle. Now changes to building regulations are being finalised this year, more people can benefit from having their own off-grid getaway.

Scottish planning (zoning) policy requires all developments to get planning permission for a new build from their local authority. This involves providing a description of plans on the chosen location. This part of the process will not change and will still have to take place.

However, single storey huts will no longer need a building warrant or have to comply with strict building regulations. This gives hut builders more freedom in how they build their huts and can significantly reduce building costs. There are still some rules which will have to be met.

Firstly, the build must fit the description of a hut as given in Scottish Planning Policy documents, which is as follows:

“A simple building used intermittently as recreational accommodation, having an internal floor area of no more than 30m²; constructed from low impact materials; generally not connected to mains water, electricity or sewage; and built in such a way that it is removable with little or no trace at the end of its life.”

By restricting size, the risk of structural instability of the hut is reduced but its energy efficiency is maximised.

Secondly, some health and safety regulations will have to be met, for example relating to fire risk and spread. A guidance document outlining these will be published by Reforesting Scotland later this year.

The Scottish Government has also allowed provision for a sleeping platform and amenities such as composting toilets within the hut. In terms of energy use and production, off-grid solutions such …

Going Off-Grid – Jump, Run or Walk

By Dovely from cherrylovefarmm.com

Figuring out how to get from where you are to that sustainable garden of Eden can be daunting. We would all like to have the money to jump. Most of us don’t. When blocked, many run into a situation and find themselves ill equipped to cope.
I’m walking.
There’s an old saying in sales. Plan your work and work your plan. Be open to the fact that the picture of your end goal may change as you move forward. We all want to find 300 acres for $50.00 an acre. I hope that you do. I didn’t. What I thought I needed and what I now have are very different. Yet, my tiny half acre has and has the potential for all of the elements I want to live a sustainable life off-grid.

As I read the Landbuddy post I see many of you are searching for others to create a community. I have found that you can have a community and they don’t have to live in your back yard. Networking and bartering with others in my rural town has given me access to things I can’t produce on my tiny urban farm. I help a friend with his fences and then we harvest dead trees from his woods for my stove. My two dairy goats need about 40 bales of hay a year. I help a farmer get his hay up in exchange for the bales I need. If I had those ten acres, I would have had to plow, plant, cut and bale an acre by myself. And I’d have to have the equipment or do it all by hand.

I came to North Carolina with the intention of using my $25,000.00 to buy more land and less house in the country. I did my reserach and had my lists. You can’t fight Mother Nature. I wanted enough winter cold to help kill bugs and chill the apple trees but not the New England snow drifts I grew up with. I wanted to be at least 150 miles from the ocean and away from river flood zones. I have seen first hand the damage from earth quakes, hurricanes and tornadoes I wanted a place where they don’t often happen. Because of the danger posed by natural disasters and human error and my aversion to nuculear power I did not want to live near or in the path of prevailing winds of a nuclear power plant. I KNEW what I was looking for…..Then I saw what is now my house… no basement or attic. No out buildings. No 10 acres and it was in town. What was I thinking even looking at this place? Well ….she is an Italian brick beauty built in 1888. All that is left of the old farm is the heart beat more than the half acre she sits …
