The document describes the design of a flashlight that is powered solely by the heat from a human hand. It does not require batteries. The design uses Peltier tiles, which generate electricity from temperature differences, to convert the heat from a user's palm into electricity. An oscillator circuit with a step-up transformer is used to boost the low voltage output of the Peltier tiles high enough to power an LED for the flashlight. Testing showed the design was successful and produced a steady beam of light for over 20 minutes in outdoor conditions, demonstrating it can run solely on body heat.
The document summarizes a presentation on a hollow flashlight invented by Ann Makosinski that is powered by body heat through the use of Peltier tiles. The flashlight uses the temperature difference between a person's hand and the ambient air to generate enough voltage to power an LED light through the Peltier effect. It can provide a steady beam of light for 20 minutes and does not require batteries, making it useful for areas without reliable power sources. While it has limitations like only operating for short periods of time, the design demonstrates the potential of harnessing body heat as an alternative energy source for small devices.
Thermal solar technology uses the sun's heat to produce hot water or electricity. Examples include solar hot water heaters, which use rooftop collectors to heat water that is then stored in a hot water tank, and concentrating solar power, which uses mirrors to focus sunlight and create steam to drive electricity generators. New technologies are also experimenting with using solar heat in desalination plants and generating electricity through solar towers.
Solar energy comes from the sun and can be used as a source of heat and light or to generate electricity. It has been harnessed for centuries through technologies like solar heating. Modern solar power plants use either photovoltaic cells or thermal systems to convert sunlight into electricity. A photovoltaic plant directly converts sunlight to electricity using solar arrays and inverters, while a thermal plant uses concentrated sunlight to heat a working fluid and drive a turbine generator. To power Arizona would require around 400 square miles of solar panels, capturing the abundant yearly sunshine to generate the state's electricity needs.

The document discusses the benefits of installing a home solar power system. It explains that while the upfront costs can be high, solar panels can pay for themselves over time by providing free electricity. Homeowners can even earn money by selling excess power back to the electric company. Well-installed solar systems last for decades with little maintenance. Having solar power ensures electricity even if the grid goes down, and increases the home's resale value. While the initial investment is large, solar power prices are rising and the system will eventually pay for itself through energy cost savings and income from selling electricity.
Hot water from underground is piped into a geothermal plant where it is turned into steam to drive turbines and generate electricity. Geothermal is renewable since the heat source will always be available. While the upfront costs of $23,250-$40,000 to install a geothermal system are high, it becomes more cost effective than alternatives like gas fireplaces or natural gas heating over the long term. Some advantages are consistent heating and lower long-term costs, but disadvantages include the large initial investment and needing to commit to staying in one home for many years to realize the cost savings.

This document discusses solar power as a renewable energy source for homes and businesses. It outlines three principles for conserving energy by reducing losses, increasing efficiency, and reducing consumption. Solar power systems, including thermal and photovoltaic, are presented as the ultimate way to reduce energy use. The advantages of solar include being non-polluting and renewable. Government incentives like tax credits help fund solar projects.
1. There are many ways homeowners can reduce their energy usage and switch to green energy sources, such as performing an energy audit, upgrading appliances, installing more efficient lighting, and using natural cooling methods instead of air conditioning when possible.
2. Individuals can generate their own green energy through small wind turbines or solar panels, though these systems can be expensive to install. Government subsidies are available to help offset the costs.
3. While green energy technologies are improving, the United States still relies heavily on non-renewable energy sources that produce greenhouse gases. Adopting more energy efficient practices and switching to renewable energy providers can help increase the country's use of clean energy over time.

Things We Wish We'd Had On Hand Before the EmergencyBob Mayer
This list is based on interviews with people who'd gone through an array of natural and man-made disasters, including extended power outages. Some items are common sense, but look around and see if you have them. Other items are things we take for granted until we don't have them.
This document describes a solar charger called Solarclip that has improvements over most other solar chargers on the market. Solarclip has both a reasonably sized solar panel and battery storage, allowing it to collect and store enough energy to continuously charge devices even when sunlight is intermittent or unavailable. This integrated solar power and battery storage allows Solarclip to sustain a continuous charging rate for mobile phones, even on cloudy days, whereas most other solar chargers cannot due to their lack of battery backup. Solarclip is designed for daily use by people who use clipboards and smartphones as part of their work.
Solar chargers provide a portable way to charge batteries and phones using solar energy instead of being plugged into the wall. They allow users to charge devices anywhere there is sunlight, avoiding being tied to an outlet. Solar chargers are convenient for camping, travel, or emergencies when a traditional charger is not accessible. They can help save money on energy costs over time compared to regular chargers that require power from the electric grid.
This document discusses the potential for installing solar power in Te Hapua, New Zealand. It explains how solar power works by charging batteries during the day from sunlight and then powering homes at night from the stored energy. For Te Hapua to be suitable it would need sufficient sunny weather. Installing a large solar panel system could provide power to many homes in the area and pay residents for excess energy generated. The document suggests using tractor batteries as an affordable option and connecting to the power grid instead of batteries. It raises questions for locals about whether solar power would be a good investment and worthwhile for Te Hapua.
Solar panels convert sunlight directly into electricity through the photovoltaic effect. This solar-generated DC electricity is sent to an inverter which converts it to AC electricity that can be used in homes or fed into the electric grid. Inverters are useful for powering areas without grid access or as backup power sources, and they are being designed to be more affordable, efficient, and able to charge batteries for nighttime use. The example discusses how calculators and other small devices use solar cells to generate power without batteries.
The document provides information about wind power and alternative energy options for homeowners. It discusses the benefits of wind energy as the best alternative energy and explains how to design wind turbines. It also summarizes pros and cons of using home wind power systems and compares wind and solar power options for homes. Finally, it discusses remanufactured wind turbines as a popular and affordable renewable energy option.
How tesla battery storage compares with rivals on prices renew economymartinchem
The document compares the pricing of Tesla's Powerwall and Powerblock battery storage systems to competing products from Aquion Energy, Iron Edison, Eos Aurora, and Imergy. It provides assumptions and calculates the cost per usable kWh over the lifetime of the products for residential and utility-scale applications. For residential batteries, the Powerwall has among the lowest costs per kWh, though it depends on individual electricity rates and solar incentives. For utility-scale, the analysis models multiple scenarios for Imergy's flow batteries and finds Tesla and Eos Aurora have competitive pricing.
Cheap solar panels can be found in three ways:
1) Used or discounted solar panel systems from homeowners who have moved or upgraded. These can be found at a great bargain or even for free.
2) Damaged solar panel kits that are still functional but discounted for home use due to cracks or chips reducing their efficiency.
3) Contacting solar companies for discarded panels deemed unsafe for commercial use that can still work for a home and be acquired very cheaply or even for free. Cheap solar panels from China can also significantly reduce electricity bills.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

imaging, emphasizing addressing false positives and resource efficiency.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
2. This presentation introduces you to solar power as it’s a
key off-the-grid power source and expands your possibilities
not just for scavenging and sustainment, but day to day
living. It can be a life saver during a power outage, especially
an extended one.
First, I’m going to cover smaller, handheld solar power
banks and their utilization.
3. Smaller Solar Power Gear:
There are smaller items that are useful. These have lithium batteries
which produces more power for the weight.
On the dash of my Jeep, I keep this Blavor Solar Charge Pack. It has a
flashlight and a cheap compass on it. But essentially, being on the dash, it
stays fully charged. I keep it in place with Velcro strips. It gives me USB
ports to recharge my cell phone, GoPro, and smaller power banks. It’s
relatively solid and heavy, thus it stays in the Jeep.

4. The much lighter, less powerful one, is snap linked
on the outside of my daypack (so it stays charged)
and GnG for emergencies.
Dizaul Solar Charger: https://amzn.to/2WY96Sd
5. Then I have several different size smaller power banks.
The key to all this is to be able to recharge essential gear such as
cell phone, iPad, satellite messenger, laptop, plasma lighter, LED
flashlights.
One key to every charging system: Make sure you have the
cables! Nothing is more frustrating than having power available
but you can’t hook it to your phone or device.
Another key is that I keep copies of all my survival library
books in Ebook format as well as print. With power, and the
eBooks downloaded into my iPhone and iPad, I carry that library
with me everywhere.
6. LONG TERM, LARGER SOLAR POWER
What You Need To Know About Solar Power for Camping,
Boondocking, Home Backup and Survival.
I’m including this in preparation for Scavenging and Sustainment
because a power source is critical. I am not including water and wind
power because my research indicates these require a larger degree of
difficulty and because they normally require a fixed position.
Before investing money, it’s worth your time to learn about the basics to
decide whether you want to do it. If you want to get started, this will help
deciding what kind of configuration you will build based on your needs.
7. Figuring out Solar Power 101 is confusing because it’s like Computer
101. Everyone assumes you know something and they don’t do 101. They
jump too far ahead. So, this is very, very basic. I started with zero
knowledge other than the sun rises in the east (most days) and sets in the
west (usually on those same days).
Caveats: I am not an electrical engineer. I’ve been working with solar
for about two years in different configurations and environments so there’s
a lot I don’t know. Also, technology is constantly changing. What’s cutting
edge today, could be passé by the time you read this, but you will have a
solid knowledge base to draw upon.
8. The equipment is not cheap. You will not produce enough
power to recoup your costs based against your normal power
grid. However, you can’t put a price tag on peace of mind for
emergencies and off-grid uses. The payback is having an
emergency power system. Also, for those of us who take to the
wide-open spaces, it can make boondocking and remote
camping much more comfortable and enjoyable. And safer!
9. The key components are
Solar panels
Convertor
Batteries
Cables
Most people focus on the panels, but the chokepoint, not
just for solar, but for all renewable energy, is the power
storage: the battery
10. Key questions:
How much power do you need? That’s a wide-open question. I’m
not going to cover powering your home. The reality is that solar is
expensive for power produced.
I’m investing in it and learning about it for several reasons:
It’s renewable energy.
It works almost anywhere.
However, how much sunlight you get is something to factor in.
There are part of the country that get a considerable amount and
other that get less.
11. There is an interactive MAP you can scroll over to find out how your location
rates if you click on the link and go to the page.
12. Solar is a good backup at home if the power goes out. A whole house or
partial generator fueled by gas or diesel is nice, and more powerful and
cheaper than solar. However, you need fuel which is finite. We owned a
house with a whole house generator and had a 1,000 gallon propane tank.
Even cutting down on consumption (BTW, using more power DOES use
more fuel—many people think the generator consumes at the same rate
regardless of draw; it does not) we were using up over 80 gallons a day
during a blackout. Expensive and if a power outage occurs before a top off,
one could run out of power.
13. Having a decent battery bank attached to my solar lets me know that I
can run my wife’s CPAP all night during an outage. I can charge important
items like phones, flashlight, computers, etcetera. And keep on charging
them indefinitely, regardless of the length of the blackout. I can run my
laptop; some lights; etcetera, as needed.
14. There are whole house battery banks. Tesla produces what they call a
Powerwall along with other companies making the equivalent. The batteries
charge off the grid, but can also be connected to solar.
It’s worth talking to an expert installer if considering this option,
especially since power companies have different rules about hooking solar
into the grid.
However, when we purchase our next house, which we are currently
looking for, instead of a whole house generator, this is the option we will
pursue.
15. For emergency off the grid if forced to bug out.
Having a power bank expands your capabilities tremendously, often in
ways we don’t think of. For example, if forced to go off the grid, I can now
use power tools such as drills and saws and recharge them. I’m not
immediately back to pre-electricity survival. Start thinking about how
much of what you have relies on power?
16. For boondocking/camping.
I had a solar panel on top of my Wranger. For my Jeep Gladiator, I carry
two flexible 100 watt solar panels between the cab and the cargo bay. I
have my Goal Zero convertor/battery along with anywhere from one to
three additional batteries linked inside my Jeep when I go into the
wilderness. Thus I can take up to 1,200 Ah with me that can be recharged,
not just by the panels, but by the Jeep engine as I’m driving. At night I can
have a light, my laptop plugged in and recharge other devices.
Especially useful is being able to carry a more powerful compressor to
refill my tires after deflating after deflating them for off-roading.
17. In the left back

parallel.
It’s currently plugged
into the very
convenient plug at
rear of middle
console.
18. Here are two flexible 100 watt solar panels from my Gladiator on a
picnic table while camping in the Smokies. The extension cord leads to my
shelter and is charging my laptop and a light at night.
19. How many panels do you need?
A short discussion then I’ll give my recommendation.
First, you determine how much power you desire, that will decide the number of
panels. However, let’s be realistic. You probably have no idea how much power
you need for this type of usage. I’m going to focus on starting with a basic set-up
that you can build from as desired.
The panels charge your deep cycle batteries. The accepted rule of thumb is one
watt of solar per amp hour of battery capacity. Thus, a 100-watt solar panel should
be able to charge a 100 Ah battery bank. That’s under ideal circumstances, though.
The reality, and my experience, is more like 1.5 solar to 1 Ah.
Now you’re going: Amp Hour? Huh? At West Point, we all had to take electrical
engineering, EE300. It was called Juice, and renowned for flunking many a cadet
out. Let’s talk concrete terms.
A car battery holds around 45 Ah.
20. The base line combination convertor/battery I’m going to use in this
presentation is the Yeti 400. It holds 33 Ah at full capacity.
Most laptops use input voltages between 16 and 22 volts at usually 2
to 4 amps (doing the math above, this is between 32 and 88 watts).
Balance that against recharging it. If you have four 100-watt panels
in bright sunlight, technically you should be able to recharge it
quickly. However, you never want to let your battery run down to
zero. And it never recharges at 100%. Use a 1.5 to 2 factor of panel to
battery. The manufacturer says it will take a 100-watt panel about 6 to
12 hours to recharge a Yeti 400. Do your math based off that.
21. There are numerous types of solar panels but they break down into two main
groups: solid and flexible. The latter costs more, but are lighter and portable.
Renogy sells kits of two panels and a convertor, cables, etcetera, but you don’t
need the convertor if you have the Yeti 400 which I’ll cover shortly.
For my start, after researching, I split the difference and bought two solid 100-
watt panels and two flexible 100-watt panels. Why? Because I have the two solid
panels outside my office linked to a Yeti 400 in my office. If need be, in an
emergency, I could pack them and take them, but for normal use they are
relatively fixed (I have them on a homemade PVC stand with wheels, so I can
move them to reposition for sunlight). I have the two 100-watt flexible in the
space between the cab and cargo bay of my Gladiator.
22. If you want to start basic, just get one solid 100 Watt panel. There are even
smaller ones made. Shop around for your needs and your budget.
Solid 100 watt Renogy panels.
https://amzn.to/2WS4JrO
The key to solid rather than flexible is they are less expensive and heavier. The
latter is an advantage when you position them. I made my own PVC stand. I have
them on the deck behind my office. I can move the stand to track the sun, but
usually they draw more than enough on a sunny day.
23. Here are the two solid
panels on the deck
behind my office on a
mobile set up built of a
PVC pipe stand in the
back and adding wheels
on the bottom.
Note that my extra
flexible 100 Watt panel
is hooked in, but can
easily be removed and
put in my Jeep
24. Flexible: Renogy 100 Watt, 12V.
https://amzn.to/3g1BXfR
These are amazingly light and flexible. Remember, solar power
generation produces a lot of heat. You don’t want to put this
flexible panel right up against something, like the top of a Jeep,
without some form of barrier between them that can cool. I back
both flexible panels with corrugated plastic board. Very light, but
they are waterproof
25. Convertor: After researching I went with the Goal Zero Yeti
400.
https://amzn.to/2ZXLqza
Anything smaller didn’t seem worth the cost. Going larger, you
gain more battery power, but as you see below, you can triple your
power for a fraction of the cost with extra batteries. The key to the
Yeti 400 is it has a convertor and multiple plug ports as well as
readouts.
26. Here’s what my Yeti 400/33Ah is capable of, starting at full charge (not ALL of
below but any one of them):
Smartphone 20+ Recharges
POV Camera 70+ Recharges
Headlamp 70+ Recharges
Tablet 10+ Recharges
Laptop 3-5 Recharges
Light-a-Life 130 Hours
Mini Fridge 7 Hours
32 LCD TV 3 hours
You can put two three/two prong plugs into it. Also USB. You can also charge it
from your wall socket in addition to solar panels.
27. Extra Batteries. I go with traditional, not lithium. While lithium provide
more power and are good for small devices, they are much more expensive.
Also, you need to be careful wiring lithium batteries. Some things don’t
recommend lithium such as a trolling motor. There is a reason airlines, and
the post office, ask you about lithium batteries—they can heat up and cause
fires.
I use 12V, 33ah, deep cycle batteries. They cost $70 on Amazon and
weigh 23 pounds. I hook them to my Yeti 400, which increases my power
storage.
https://amzn.to/3eYEA0H
28. Cables: This was a little confusing at first and I bought one or two sets of cables I
didn’t need/weren’t right. This is specific for GoalZero and Renogy panels, so make sure
you check for whatever rig you go with.
Here is your basic cable going from the solar panel connectors to input on the Yeti.
https://amzn.to/3hzKnvq
However, unless your Yeti/Convertor is sitting right next to the panels, you’ll need a
longer connecting cable to attach to the previous cable. Here is the 15-foot extension
cable I use in the Jeep: https://amzn.to/2EcdbLY
Here is the 30-foot extension I used for my patio into office: https://amzn.to/30MhcOX
Here are the cables needed to connect your spare 12volt batteries to the ports on the
side of the Yeti 400: https://amzn.to/2CE60fq
To connect two panels together, you can buy these Renogy MC4 Y Branch connectors
that come in in pairs. They take the cables from the panels and merge them into a single
port.
https://amzn.to/3jHsXyD
29. One thing you’re realize is that the cables coming
out of the panels are short. You don’t have a lot of
room to play with unless you have extra cable. There
is a reason for that: the longer your cable, the more
power you lose.
A useful tool is essential as the connections are very
tight is the Renogy Solar Panel Connector Assembly

30. Vehicle Mounting: How much roof space do you have? If you have an
RV, you have a lot more space. For my Wrangler, when I add in the
supplies I carry on my roof rack, I only have enough space exposed on the
roof for one 100 watt, flexible panel. However, the way I’ve configured it,
I can carry two in the same space, both with corrugated plastic backing.
One exposed to sunlight while I’m driving, the other below. Then in a
base camp, I can unscrew the top one, hook it to other and have 200 watts.
I followed a Youtube video (kind of, sort of) for the mounting.
Here is the video I used as my base guideline:
https://www.youtube.com/watch?v=hROYaqY83v4
I will say the EternaBond tape works really well and I used it in other
areas. https://amzn.to/3jzw0Jr
31. A flexible 100W solar
panel on top of my Jeep.
It’s attached by six wing
nuts and can be removed
or the second 100W panel
can be placed on top and
both displayed at a base
camp.
The wire runs inside the
Jeep where a Yeti400 and
extra battery are installed.
32. Vehicle Mounting: For my Gladiator, I carry the panels in the space
between cab and cargo bay. I actually like this set up better because
the Yeti is charging while I drive, via the plug in the back of the
middle console, and when I stop to camp, I don’t have to park in
sunlight. I take out the two panels, lay them in sunlight, hook up the
cables, and run an extension cord.
33. This is a very basic introduction to solar power.
Technology is constantly changing and I’m always learning new
things. I’ve included this information in the latest edition of The
Green Beret Preparation and Survival Guide.
I’d like to hear from those who have more experience with their
suggestions and comments.
