TEOMCROTE = TEOTWAWKI on steroids! The End Of Mankind's Current Reign Over The Earth takes into account that our ancestors were neither suicidal, stupid, nor our genetic inferiors but still wound up getting wiped off the Earth. Whereas CSER [cser.org: Centre for Study of Existential Risk] tries to PREVENT this dispensation from coming to an end, TEOMCROTE works from the eventuality/possibility/probability that the end our age takes place and what to do then

Energy Systems


this was a discussion under Earthgate Atlantis

We need to consider lots of different sources of producing energy, the most natural choice will be to harness the power of the stream running through the valley, we should also harness the natural wind that runs through a valley, so a windturbine/s will be almost essential.

Below is a fairly good link on a simple home made turbine:

We can also human energy, hand crank generators, bicycle generators, steam generators, biomass generators, I think the choice is almost endless and we should not allow our imaginations to be limited to just a few options.

What's your ideas??

-------------------------------------------------------------

are there funds for buying the parts?
It may be cheapER, doesn't mean it's cheap...

------------------------------------------------------------

Regarding the water turbine.

I think I have found a way of using the electricity generated without storing it in batteries. If my understanding is correct, then as long as the water that is passed through the turbine is constant, so generating a constant 300 watts (for example) 24/7 then we would only need two pieces of equipment, and that would be an Inverter and a Regulator. Now, if we don't plan to use AC equipment, or if we can convert the AC equipment that we plan on using into DC, then in theory we should be able to remove the Inverter from the system.

Does that sound about right?

Now, if this works the only problem I can foresee is if we get a big old tropical storm, that gives a lot of rain and that gushing through the valley would cause the turbine to go into overdrive, hence causing any electrical items connected at the time to blow up.

Yes, No, Don't Know??

------------------------------------------------------------

2 things:
This turbine has an inlet, i suppose. Only so much water can ever go through that inlet, doesn´t matter how much goes over or around it, it would seem to me.
Besides, there´s like once or twice a year that a really big storm comes by. Actually, sometimes it´ll skip a year.
A good rain will cause a greater flow but even those only happen a few times a month during a few months in the year. I´m guessing the turbine can be shut off manually IF necessary.

Also, i once was looking for appliances that run on 12 volt and BOATS have these and there are loads of boats on islands, so acquiring these shouldn´t be a problem.

----------------------------------------------------------

About wind turbines, I have a source for very basic, cheap, but effective turbines.

I purchased one from ]rusticpower

Having seen one and used one first hand I know how cheap they are to fix and build.

I think it comes down to how much power do we need? Do we plan on living by candle light from day one? Or should we find other methods of lighting that require less energy and cost, eg; LED lanterns etc.

We have %3ELED+[sign in to see URL]]one with a built in lead acid battery

-------------------------------------------------------------

i think wind energy is very underappreciated. I looked into what they produce and IF YOU HAVE WIND, like on the island, they're a superior source of energy: affordable, much higher yield per investment than solar, and therefore allround simpler to do.

I'm amazed that one doesn't see such turbines everywhere. Once in a while one sees solar, but wind? Forget it.
There are, however, a number of boats on the island with wind turbines that i've noticed.

I do wonder what the local legislation has to say about so-called landscape pollution and wind turbines.

-------------------------------------------------------------

The turbine that I have is very small and silent, it would hardly be noticed, can't be any more annoying than a barking dog!

I did read that they are investing in sustainable energy on La Gomera, and possibly else where in the Canaries.

---------------------------------------------------------------

the Spanish/Canary govt isn't necessarily our enemy, but we require a Spanish (native) speaker who doesn't mind looking into such matters.
Did i mention that they actually pay subsidies to people who take abandoned landplots into production? [I think i did]. Could be that we rent/buy the ruin and could live off of the money we get from the govt for using the terraces. But we'd have to figure out how that works first...

--------------------------------------------------------------

My Grandad speaks fluent Spanish, both my Nan and Grandad retired to mainland Spain about 20 years ago. Do you think it would be worth contacting the Government about creating a Permaculture Project in the valley? We don't have to mention about bunkers or the end of the [sign in to see URL]

Just mention the benefits, such as possible local job creation, tourism, sustainability, new ways of doing this in semi-arid climate. I am sure if we mention the words climate change and sustainability and money enough times in our proposal then I am sure we would get some positive [sign in to see URL] I sound a bit cynical?? LOL

]from article at OffTheGridNews

Residential wind power was slow to be adopted by homeowners because of the early model’s large size and low power output. The challenge for these early designs was that they were based on their very successful commercial brethren and didn’t really perform well in residential settings. The reasons for this were that even though these residential versions were smaller than the commercial units they borrowed their design from, they were still too large for many homes. They also required a very strong and steady wind to operate and had to be raised up in the air on a very tall and expensive tower to find this type of breeze. This tower would also create complaints from neighbors and led to many areas enacting rules about where these types of systems could be installed.

All of these problems have been addressed in modern versions of these wind power systems. The design of most modern wind turbines has changed to make them smaller and lighter, which allows them to harvest the slower and bursting wind typically found in most neighborhoods. Because of their smaller size, they don’t require the larger towers the older versions needed and most of these new wind turbines can even be mounted directly on the roof of your home. This helps to lower the installation costs and makes it easier to service the turbine if needed.

In addition to their smaller size, these newer wind-power turbines are also more efficient. Changes to their designs allow them to generate substantially more power from an average breeze than older models. This increased efficiency is due mainly to two design changes in these newer turbines.

First, the blades are designed to harvest more of the passing breeze. Where older blade designs only reacted to the pressure of the wind known as “drag”, these newer models can also take advantage of “lift”. This allows these modern wind-power turbines to spin in slower winds, which means they are productive for more of an average day. These new blade designs also enable these turbines to spin faster, and more revolutions equates to more power being generated.

The next big change in these newer wind-power turbines has to do with the generators used in their design. These generators are connected to the shaft that is spun by the blades and is the part of a wind-power system that creates the actual power. Modern generators present less of an obstacle to rotation because of improved materials and bearing designs. This allows the blades to react to lighter winds and actually spin the generator at these lower speeds. These newer generators are also more powerful and can produce a higher output of power from a single rotation. These two factors combine to allow these wind turbines to provide far more power than older versions in a given day.

Modern versions of these wind power systems enjoy another advantage over other alternative energy solutions (like solar power) in that they can operate day or night as long as the breeze is blowing. Even the most efficient solar power systems available can only operate for a portion of a given day and are actually dormant for more of the day than they are active. Most wind power systems can’t produce nearly the amount of power as a typical solar power solution, but they are active more often and can help to close the gap between these systems over time. In fact, many homeowners install a wind power system on their home along with a solar power solution to allow this complimentary technology to augment the electricity the solar power system provides.

Installing one of these wind power systems is simply a matter of mounting a wind turbine on your home and connecting it to your electrical system. Some of these units require an inverter to transform the DC current they produce into AC current that can be used by your home. Other models have a small inverter included in their design and can actually deliver AC power right to your home. This makes the installation very easy and allows a homeowner to do most of the work themselves.

Hybrid Energy-Wastewater Tech


]Hybrid Energy Tech Could Clean Wastewater for Free
- Many microbial fuel cell designs have a water-filled chamber divided in two by a semipermeable membrane that allows protons to flow through in one direction. An electrode in each chamber connects the chambers to whatever is to be powered by the fuel cell, forming a circuit. In one chamber, microbes attached to the electrode munch organic molecules in wastewater. As they do this, they split the molecules, giving off electrons, protons, and simpler molecules such as carbon dioxide. The protons pass straight through the membrane, setting up an electric potential between the two chambers. The electrons flow from the electrode through the circuit to the other chamber, where they combine with the protons and oxygen to make water.
- If you flow saltwater through the center channel and freshwater through the two side channels, osmotic pressure will drive the ions across their respective membranes. One side channel becomes negative and the other positive—essentially creating a battery.
- Combining the two technologies overcame both weaknesses, says Logan: “It’s like a turbocharger.” The combination lowered the number of stacks required for RED to 5 instead of 20 and raised, by more than seven times, the amount of power the fuel cell generated when fed a diet of domestic wastewater.
