The task is to adapt a widely available thermostatic valve for use in the solar water pasteurizer. The thermostatic valve that will be used comes from the coolant system in automobiles.
A simplified means of using natural fibres to create a menstrual pad is described below.
Compound parabolic concentrators (CPCs) can be additions to solar water stills, solar water pasturizers, and solar cookers. CPCs can increase the output of these devices along with their efficiency by concentrating the sunlight to make the device more effective.
This type of pump uses an adjustable PVC piping system to vary both the depth of the system, and the force needed to bring up water. The pipe is able to be lowered to a desirable depth, and locked in place, so that it remains rigid while in operation.
Solar water pasturizers can help clean water in poorer communities but a barrier to their popularity in those countries are their high capital costs, which primarily come from the heat exchanger cost. This study explored different materials/technologies to reduce the heat exchanger cost while also optimizing its performance.
The presented treatment unit serves as a means to reduce turbidity in water to be subsequently treated with solar water disinfection (SODIS) technology. The unit is comprised of a well-graded sand filter through which turbid water flows and subsequently settles.
This work offers a primer to the topic of AWVPs, and a description of how to build a dew collection rig. Unfortunately, dewfall is not currently recorded in most standard meteorological archives; so the next step for this project is to offer a reliable means of regional assessment that is accessible to a layman.
Flowmeters are the devices that are used to measure the flow of liquid & gases that pass through them. This flowmeter is 3D printable.
This 3D printable device is a portable, easy to use unit that uses a limited amount of water. Could help prevent spread of sicknesses in a village or house without access to running water.
The basic design are buckets that can be suspended by any rope over each other with holes in the bottom to allow excess water in each bucket to spill through and water the next plant below.
An open looped, solar hot water system was repaired in Humboldt County. Both of the dribble valves were replaced for this repair.
A passive solar heating system was designed, built and installed on the roof of Hotel Perote in Parras de la Fuente to heat the hotel's pool. This design utilizes PVC and copper piping to heat the pool water to 28 degrees centigrade from October to March.
Used to evenly water plants from a central location using a timer and a water pump.
Using light to kill germs in water is a effective water purification technique. It works by using light, sunlight or more effective, UV light, to disrupt the germ/bacteria DNA, causing them to become harmless. This can be done by filling plastic or glass bottles with water then letting them sit in the sun for extended periods of time.
Our objective for the water project for the 2014 Practivistas Dominicana Program in La Yuca is to replace the flat piping system, used to catch rainwater runoff from the roof, with a gutter that will obtain more water.
The objective of this project is to provide inexpensive potable water and water for cleaning to the local school in La Yuca, Santo Domingo by use of rainwater catchment. Replacing purchased water with captured water may allow funds to be allocated for other important services.
This project is for greywater usage and may not meet clean drinking water standards. (not potable water)
My design uses a 3D printable pump to allow the user to pump the water out. This has several advantages. It allows better control of the amount of water being used and therefore has the potential to decrease water usage meaning that you will need to fill your bucket less often.
Rope pumps are an incredibly easy and cost effective way of raising water to the surface. The main hindrance is the valves that go on the rope. This 3D design cuts down production materials, energy and cost.
Nitrate, the most oxidized form of nitrogen, is regulated to protect people and animals from harmful levels as there is a large over abundance due to anthropogenic factors. The leading certified method to detect and quantify nitrate, demands the use of a toxic heavy metal. An alternative eliminates this problem but requires an expensive proprietary spectrophotometer. The development of an inexpensive portable, handheld photometer will greatly expedite field nitrate analysis to combat pollution.
Makeshift water piping has been a massive undertaking in Nepal especially where an earthquake devastated the area a year ago. Organizations such as Field Ready are hard at work making sure water supply systems in the area are sanitary and helpful for those who need it. The T-fitting module was specifically requested by Field Ready
This OSAT is a heavy-duty rope pulley that can be used to raise water from a well. This pulley can be customized to any desired size, and can be paired with multiples of itself to further increase mechanical advantage.
While many of the rain water harvesting systems are designed for non-potable purposes, the water can be purified by use of local resources like charcoal, ceramic/clay pots and cotton sleeves.
This device collects rain water in a water bottle or any container that has standard bottle threads. It includes a purge container that collects the initial dirty rain water.
Design and install a safe, easy to use and maintainable rain water catchment system.
This OSAT project is the design and prototyping of a hydraulic ram pump. This pump features no motorized parts and can be left unattended for extended duration with minimal upkeep.
solar water heater
I developed this saline water filter for the obvious reason of converting water from the ocean into potable drinking water for those without access to it. The concept behind the filter is extremely simple; Using solar energy in the form of sunlight to evaporate and then collect the fresh water.
The proposed design demonstrates two innovations: the use of cloth filtration bags to contain the filtration media - the ease of removal of the bags simplifies regular cleaning and permits simple modification of filters as seasonal conditions dictate.
A solar hot water heater was installed at a location on Haeger Avenue in Arcata, CA. This is a closed loop system with a storage tank that has a drain-back gravity feed unit.
Solar energy has many uses such as electricity production and heating. There are many projects described on appropedia that show examples of heating water, dehydrating food, producing electricity with solar panels, building solar cookers and other inventive solar devices, among many more projects. There are numerous benefits to solar energy in any form that include supporting a renewable energy source, reducing electricity bills, rebates, and advancement of photovoltaic technology.
A solar funnel is a device that allows light to be reflected to a certain point for the desired purpose. This page suggests different ways to determine the tilt angles of the sides of the solar funnel to get the most desirable outcome.
Solar powered ice makers can use sunlight to produce the electricity required to power a solar ice maker, or use the sunlight as a catalyst to a chemical reaction to keep an ice maker cool. Solar ice makers can be helpful for disaster relief, refugee camps, developing nations, and camping. This page gives examples of solar ice maker projects.
Solar orientation is important for many modern day applications and is dependent on location. There are many aspects that affect solar orientation that should be considered in any application where solar orientation should be a factor.
A solar wiki provides information on topics such as solar hot water, photovoltaics, solar cookers, solar water disinfection, passive solar design, along with other, more specific topics.
This 3D printable straw filter should allow for cheaper and more readily available access to clean water at a lower price as most of the components of a water filter are things we come across every day.
Talbot water taps are used extensively throughout the low income countries of the world. This type of tap is extremely useful for them, but is often quite expensive to purchase; sometimes so expensive that they can't get them. This type of tap allows for automatic shutoff of the water when it is released due to the water pressure pushing it closed.
