Staying Cool in the Summer Heat — Class Notes

Class Notes

Staying Cool in the Summer Heat

As we work through the coming week, let’s build on the most recent Weekend Homework, continue our conversation, and our preparedness planning, with a focus on the importance of low tech solutions as key components of our critical infrastructure.

We love the sun and the playful activities of summer! We love it all even more so when we can seek the reprieve of shelter and shade. Staying cool in the summer heat is something we can learn to do using simple ideas, and relatively low levels of technology. These ideas are important not only for human comfort and safety, but also for greenhouse gardens and food preservation too.

We’ll all fare much better when the grid goes down if we’ve invested ourselves in skill building beforehand. Read. Add books to personal libraries. Watch tutorial videos. Create notebooks with important information, ideas, and instruction.

Here are just a few of many ideas to stir the imagination, and inspire your solution-focused thinking!

Zeer Pot

Although the Zeer Pot may not produce modern levels of refrigeration, it does provide a cooling benefit. In any environment requiring low tech solutions, this one is worth considering. It’s excellent as well for teaching and learning about heat transfer and cooling processes. Create your own Zeer Pot as part of a summer project for the family, or find a way to work it into a home school curriculum. The article below is an excellent overview.

Evaporative Cooling and Geothermal Strategies

Shade cloth can be tremendously helpful in cooling a greenhouse on hot days. Shade cloth is available in varying densities, and is a passive solution. It’s affordable, and easy to use (seasonally or year ’round). In fact, you might find that your plants fare better with a little bit of shade. In the hottest days of summer, people fare better too!

As a supplement to the shade cloth, consider misters for their evaporative cooling effects. These are remarkably effective, and relatively low tech. In a grid-down scenario, supplemental power from a solar powered water pump will be needed to create water pressure in a system like this one. But don’t despair. This is doable! Solar panels may also generate enough electricity to run modest fans for the benefit of air flow.

In addition to these ideas, consider a low tech geothermal system designed to draw cooler air from piping placed below ground. This strategy is best considered as part of your preliminary design planning. If an in-ground, or partially in-ground greenhouse is an option, this may be another worthwhile consideration with geothermal benefits.

Dehumidifers work differently than air conditioning units. By drying the air, they make a warmer environment much comfortable. They an also help reduce the demands placed on today’s HVAC units. In and of themselves, dehumidifiers draw far less power. This level of supplemental tech will require the energy support of a solar system during should the grid go down, but should be much more sustainable over a long period of time.

Root Cellars

Root cellars are an excellent consideration for the food storage of any homesteader. These were popular among the generations of our grandparents and great grandparents. Root cellars are often found, even today, in many rural parts of the country. Consider adding a dehumidifier with solar support as an added benefit as needed.

Earth Ships

Earth Ships use passive geothermal systems to draw cool air through tubes buried in earth. Warmer air from within the homes naturally rises, and is allowed to escape through vents or window portals. The movement of the warmer air up-and-out pulls cooler air from the buried tubes, and into the living space. Built beneath earthen berms, there are lots of fabulously creative designs and ideas for Earth Ship living.

Ice in the desert! This is the brilliant innovation of ancient people.

Posted at The Culture Trip: “This Ancient Technique to Make Ice in the Desert is Mind Boggling”

“Making ice in the desert? The irony is in the sentence itself, as most people can only fathom making ice by using their freezers, in a practical and modern manner. However, people had figured out how to make ice in the desert over a millennia ago. This practice requires an ingenious structure called a yakhchāl, and was used as far back as 400 BC.”

Surprise Geomagnetic Storm – Flash Traffic

This was unexpected. The Earth experienced a strong, level three geomagnetic storm last night, jacking up the KP Index to a level 7. NOAA, NASA, the ESA and IPS in Australia all failed to predict this. The reason this was so unusual is that the solar wind speed peaked at only around 500 kps, which is stronger than ambient solar wind but much weaker than a typical CME (coronal mass ejection). In other words, there is nothing in the history of studying these events to suggest that a mild CME from the eruption of a small plasma filament, that barely hit the Earth with a glancing blow would produce such a strong geomagnetic storm. Now, although a level 7 KP reading isn’t necessarily worrisome in terms of a solar kill-shot, there aren’t many possible explanations for such a strong storm from such a small CME.

So, what does this mean?

As many know, the Earth’s magnetic field has been weakening significantly. In 2000 is had lost 10% of it’s strength since the 1800’s, another 5% was lost by 2010, and we know that further losses were measured in 2015 and 2017. What this event suggests is that it may actually be much weaker than we realize. This makes the Earth extremely susceptible to future solar storms, and we are now entering solar cycle 25, with sunspots and space weather ramping up to a peak in 2025. The risk to the grid, and thus our way of life (electricity) is considerable.

So, we’ll ask again: What are YOU preparing for?

Prepper Lists

Prepper Lists – A New Way to Think About Preparedness Planning
Prepper Lists
A great addition to your collection – buy it here!

Prepper lists are everywhere! They keep us organized, provide important reminders, make our planning efforts more efficient, and are easy to write, review, and update along the way. Within the preparedness culture and community, lists are wonderfully and terribly familiar. We are grateful for them even as we wonder whether the lists on which we rely are truly complete.

In addition to comparing, contrasting, merging and purging lists, let’s consider a new way to think bout preparedness planning. As you contemplate your supplies, and how best to shore these up, imagine a specific activity or supply item.

Sometimes it’s best to start with a simple example, and one that leads to a broader understanding that can be applied to the bigger preparedness picture.

Let’s start with shoes. Shoes? Sure! Shoes. Spare pairs of shoes and boots are key preparedness supply items, and would be especially important if there were an interruption to supply lines for any reason. We wear these everyday, and we need them.

Beyond the shoes or boots themselves, we ought to consider accessory items that are important to functional use, comfort, care and keeping, and longevity. Think shoe laces, shoe inserts, and shoe repair kits.

Imagine getting ready for the day… Before slipping on your shoes, you’ll be sliding your feet into socks! Your plans for shoes and boots among your resources should include a solid stash of these. Include soft socks, wool socks, ankle socks, full length socks, and socks that support circulation.

While you’re contemplating your feet, be sure you have good ankle supports, nail trimmers and other pedicure care kit tools and supplies, corn pads, ointment and bandages for blisters.

Repeat this process through the activities of a usual day, week, month, season, and year. Use the same approach to imagining emergency scenarios, or as you step-through dry-run training exercises.

Think comprehensively with an eye both to overview and to detail. It’s a strategy that extrapolates well to a whole host of preparedness concerns, and should be considered in every aspect of your planning. Your goal should be to fill in the gaps, discovering (and remedying) these now while you have the opportunity to review, revise and refine your planning – and not in a time of true emergency.

Remain steady. Stay well. Be safe, everyone!

EMP – Risks on the Horizon

The Existential Threat of an EMP – Electromagnetic Pulse Weapons and Modern Warfare

EMP weapons are among the most dangerous within the modern warfare arsenal. Dependent on electronics of just about every aspect of life, an electromagnetic pulse could devastate the very systems on which the lives of people around the world rely. The EMP is not a matter of mere inconvenience. It is, in fact, an existential threat.

Should the electrical grid go down, there would be no access for many to clean water, warmth in the winter, air conditioning in the summer, or the refrigeration of food. There would be no electronic access to gas pumps, credit and debit transactions at the grocery store, access to financial records, or banking services. Without access to electricity, the systems that support supply chain management would fail with implications for the delivery of life sustaining and life-saving medicine. Our personal vehicles rely heavily on electronic controls for both mechanical operation and navigation, and modern aircraft are designed to fly by wire. Our daily communications with family, friends, neighbors, colleagues, and coworkers rely on the same. Grid loss has implications for every nook and cranny of life.

Dr. Peter Vincent Pry is a preeminent authority of the subject of electromagnetic pulse technology, its use in acts of terrorism and war, the vulnerabilities of our systems infrastructure, and the steps we must take as a nation (and the world) to protect humankind from the catastrophic results of an EMP event. …and he has been sounding the alarm.

Linked below are books of potential interest on the subject of EMP, and resources and reading in the news. We’ve also included additional helpful site links and lots of reading references. Emergency preparedness is important to every individual, household and community. It should be part of everyone’s thinking, personal and family emergency planning, and broader preparedness culture.
