How scalable is solar-powered garbage disposal

The world is getting warming, and one of the natural disasters is garbage. The government has taken many measures which are meant to save the planet and go green. How many of these methods are effective?and how well the people are following the procedures?

There are many questions which needed to be answered. However, the measures which were taken by the government are huge, and some of them are working. There are few things which you can do to add some value to the environment, and you make that little effort to make the environment much better.

The latest technology has allowed us to many different things which are small, and they do not much of your precious time, and they are efficient than the bigger projects.

Solar-Powered Garbage Disposal?

How Scalable is Solar-Powered Garbage Disposal?

You can put the solar-powered machine to get rid of the garbage without affecting the nature. With this method, you are not only getting rid of the wastage but also making sure that th8e rivers, lakes, places and other places are not getting polluted.

If you are wondering how the process works, then let me take you on a short tour of how well it works and also explain to you how you can do it too. Nobody can tell how scalable it is, but you can try it yourself and learn about it.

Things You Need

A Large Lens

A solar powered does not describe you about the instrument used in the process. What you need is a big lens or big magnifier glass. The magnifier glass come at a low price as well and you perform the task at your home. Let me warn you that the magnifier glass needs to be placed at the center and the sunlight will be concentrated into a location.

A Big Glass Chamber

The chamber is required and ensure that it should be a glass flask for the experiment. If you have a better idea for this glass house replacement, then we would like you to suggest in the comments section. Make sure to add sufficient water to it, or you can damage the glass.

Insulated Steel tank

Once you pour enough water, then you need a semi-sized insulated Steel tank that can fit into the flask into the chamber without any issues. Remember, it is important that the tank is insulated.

Precautions

  • Remember, when you are using the big magnifier then make sure that there is nothing that can start a fire and protect yourself skin as well.
  • Once you are finished with the experiment, then do not remove everything. Instead let the flask cool down then disassemble it.
  • Make sure that you are performing it in out open, not in the house or balcony.
  • If things are not going as planned, then ensure you are taking a step back.
  • In the case of the emergency, keep a fire extinguisher with yourself.

Conclusion

If you are planning to take this process to another level, then you buy a solar machine to get rid of the wastage. If you have any questions regarding the topic, then make sure to comment below to get some answers.

Freight Farms sow their seeds

Today Freight Farms launched their first, finished, farm in a shipping container. The co-founders Jon Friedman and Brad McNamara were joined by Senator Moore, Congressman James McGovern and Mayor Joseph Petty for the official grand opening.

Their farms are built inside recycled shipping containers lined with insulation to provide the maximum reduction of unwanted heat loss possible. The outside of the containers are topped with photovoltaic cells to provide power for the air conditioning and energy efficient LED lighting within. Plants are grown using a hydroponic growing system with LED lights targeting the exact wavelengths of light required by plants to flourish. Using LEDs for lighting keeps heat generation to a minimum and maximises the conversion of electricity into useful light with a minimum of waste.

Freight Farms

The idea was originally pitched on kickstarter.com and quickly surpassed their initial goal of $26,040 finish at just under $31,000 at the end of 2011. Now 11 months on the first build is complete and ready for full farming production!

A huge congratulations to Jon and Brad for all your hard work and I wish you the best of success in this venture. I look forward seeing how you progress.…

Farming lessons from cannabis growers

When it comes to producing very high yields per square foot of growing space there are very few who can come close to the yields produced by commercial cannabis growers. The wikipedia page on cannabis cultivation is an epic 11,000 word overview that provides a huge amount of detail on different techniques and solutions available for growers and this barely even scratches the surface of what is available online.

Cannabis farms are highly illegal in most of the western world and as a result are often concealed indoors away from the prying eyes of the authorities. As a result of this, farms are frequently kept in windowless rooms such as basements, loft spaces or warehouses and sheds. One of the results of this, other than being able to evade detection, is that the growers have 100% control over the farm’s environment with levels of temperature, water and light all fully managed by the farmer. This tight level of control gives organised growers laboratory conditions for maximizing yields per square foot.

the farm’s environment

Farmers use a wide variety of techniques to squeeze every last drop of growth productivity out of the plants with techniques such as reducing the number of hours of sunlight a plant gets after a fixed growth period to invoke a hormone response that increases the harvest weight, controlling and changing the food inputs depending on the plant growth cycle stage and so on. If the research and rigour applied to cannabis farming could be applied to legal urban farming of food plants, urban farming could become very profitable for farmers in small spaces.

Farmers build a rooftop farm in Basel, Switzerland

Two urban farmers Roman Gaus and Andreas Graber from Berlin are realizing their dream of a rooftop farm following a successful trial and demonstration with a small mobile aquaponic farm built around a standard shipping container. Each miniature farm produces enough fresh vegetables and fish to feed three people for a year and uses 90% less water than traditional farming as most of the waste water is returned to the system instead of draining off away from the food production area.

UrbanFarmers Box

Their simple yet effective solution consists a barrel of fresh water fish inside the shipping container and a small greenhouse situated above. The waste products of the fish are the ideal nutrients for the plants which are grown hydroponically using the water the fish live in.

In his excellent presentation, Roman describes the current state of rural agriculture and need for a solution for the growing population with a finite amount of farming land. He discusses the potential for an aquaponics based solution that brings us much closer to a closed loop system by recycling the waste products of fish farming into food for plants. Following the successful trial and demonstration of the single unit box farm, Roman and Andreas have designed and are almost finished building their first rooftop farm in Basel, Switzerland which will produce 5 tonnes of fresh vegetables and 800 kilograms of fish per year; enough to feed 100 people from the otherwise unused roof space of one small building!…

Farmers for Chicago, a Network for Farmers

The Mayor of Chicago, Rahm Emanuel, has launched a program to create five acres of urban farmland in the city of Chicago over the next three years. Plots have been allocated on vacant city owned land in a move to create jobs and educate local residents on aspects of food production that usually takes place far away, out of sight and out of mind.

Urban Farm Network Chicago

Local farm collectives are set to work with the city to offer a training program to those struggling to find work. Like other initiatives that help people develop new skills to open doors on new employment opportunities, the hope is that graduates will not only have a greater understanding of where their food comes from but they will also have the knowledge and skills to continue on with their own farms and commercial food production ventures. By keeping the farms in close proximity the city is aiming to build a close network of urban farmers who can share knowledge and train others, spreading the knowledge further and bringing benefit to the whole community.

“Once made available, these vacant lots will help stabilize communities by bringing productive activity to areas that need it around food deserts. Farmers for Chicago will give local residents a chance to not only learn how to grow food in their communities, but also build their own food enterprise.” – Mayer Emanuel.

Modular urban farms using shipping containers

In Dr. Dickson Despommier’s ‘The Vertical Farm’, Despommier discusses the need for urban farms to be ‘cheap to build, modular, durable, easily maintained, and safe to operate’. To me, the ‘modular’ part of this statement stands out as the most important point. By making urban farms modular it is easier to scale them by simply adding more pre-built units and easier to repair by simply disconnected a broken unit and isolating problems until they can be corrected. Each unit could be dedicated to a specific ecosystem allowing multiple crops to be grown in different containers with different climates without impacting on each other.

Google has already taken this approach to building data centers by creating ‘google pods’, standard shipping containers filled with all of the servers and airflow equipment required in a data center and assembled offsite for transport and installation at the desired location. Power, air conditioning and network connectivity are all handled separately at the installation site making all ‘pods’ simple to manage and interchangeable. The ‘pods’ are plugged in and out in the same way we install a washing machine into our homes.

The shipping container vertical farm

This shipping container approach could be applied to modular vertical farms. By replacing the corrugated sides with a transparent material such as plastic or glass it would be simple to create stackable greenhouses. Add inlet and outlet pipes for water flow and ventilation and a power connection for running lighting during the winter months and you have a portable, scalable, stackable, modular, urban farm design.

By removing the power, water, and air circulation from each unit you can service many units with one system, if you choose too, but then split them apart quite easily for the next grow run if you wish. This would also be a good way to ensure standardization across the board. With all containers using the same pipe widths, power sockets and voltages, the cost of production would decrease while maximizing the efficiency of installations with guaranteed quality of components. As the containers are portable they could be installed anywhere in the world and therefore standardization is a must, not a nice to have.

In the immediate future, cost is a potential barrier to entry with a single shipping container selling for £1,500 – £2,000 at present. However, being able to stack greenhouses several stories high without needing to build a permanent structure could provide the required cost savings when deploying at scale.
