Abstract
A greenhouse has an irrigation system which comprises collecting condensation from crops arising out of evapotranspiration. The system may also capture dew. The greenhouse may have a roofAwhich causes humid air to condense, the water being collected by internal guttersBat the sides of the roof. The inner side of the roof may have a super hydrophobic surface or capillary fluting to the underside to encourage condensation. The sidesCof the greenhouse may capture dew or fog capture on fine mesh materials, the liquid being collected in secondary guttersBat the base of the mesh. The mesh may be height adjustable. The water collected may be filtered and stored in a storage tankJ. The greenhouse may have a translucent thin film photovoltaic power generation unit in the roof.
Description
Heliocycle -A Device for Irrigating Crops in the Desert Using Dew
Background
Globally, the number of people continues to increase, as does the amount of water used. In many of the more arid parts of the world, demand for water considerably exceeds the ability of natural systems to sustainably supply. As a result of this, underground water sources are being overexploited. We are effectively mining the water rather than harvesting it. Once this ground water is gone, there will be no further regular supply, and those people presently depending on the groundwater will face serious problems. For the rich, it is simply a case of bringing in water from more distant sources, desalinating water, or relocating to a more favoured location, however for the poor, it means failed crops, thirst, drinking dirty water, poor health, and very often a slow premature death.
Current desalination technologies are too expensive, and too energy intensive for general application, especially in the poorer arid regions. Hygiene and health, agriculture and food supply are thus compromised. Were sufficient resources made available for example using aid from developed nations, supplying adequate water using conventional distillation or reverse osmosis would still be problematic, and may ultimately result in an increased climate change pressure due to increased use of fossil fuels.
This invention increases the available water supply for irrigation by replicating on a small scale the hydrological cycle by which water is evaporated by the sun, condenses, and falls back to Earth as potable fresh water. The water produced by the system would be primarily for irrigation; however, it would be possible with basic filtration to bring it to potable quality.
Heliocycle Heliocycle mimics on a small scale the hydrological or water cycle by which water evaporates, rises, condenses and falls back to Earth as rain.
The Heliocycle device Consists of a height adjustable lightweight plastic roof over a cultivated area. The underside of said roof consists of a large surface area "capillary structure" designed to ensure that any condensation runs down the underside of the roof and into gutters, down through flexible pipes and into a shaded and covered water butt for collection. (A good cover is important to prevent mosquitoes from gaining access to the water -so risking malaria and other insect borne diseases) In this way, the Heliocycle collects water to replace that lost by transpiration, and keeps it clean and safe for use when needed. As well as the main roof capturing water by condensation, the sides of the device consists of fine mesh capable of capturing dew, this being an important source of water in certain coastal deserts. They likewise run down into gutters and are captured in a covered water butt. The Heliocycle is scalable, modular and inexpensive permitting the provision of water at modest cost.
Potential locations for use In order for this invention to function, it is necessary that water condenses. For this reason, coastal deserts with high diurnal temperature variation are likely to be best.
Areas with periodic fog blowing in off the ocean would be ideal. In such locations, a cool surface can reach dew point -particularly at night, and so condense water out of the air. By placing the device over crops, evapotranspiration results in higher absolute humidity than the outside air, so that in still night conditions, some of the water recovered will have come from the biological processes of the crops under the Heliocycle cover.
Components The Roof Structure The roof of the Heliocycle has much in common with a tent, with the support structure made up of flexible fibreglass "tent poles" or locally sourced products of equivalent function held in a curved shape by cord under tension to form an arch. An alternate would be to use similar materials or bamboo to form lightweight "A" frames, giving a fixed pitch roof rather than a two dimensional arch. The length of the structure is kept constant by attachment of the four corners of the roof to upright corner posts, and held in place by guy ropes in the manner of a tent. The roof is tied or otherwise fixed in place at the desired height by means of its attachment to the corner posts. Height could be adjusted at will by manually raising or lowering and reattachment at the new height, (rather like raising or lowering a flag) or be adjusted by motorised mechanisms similar to those used for raising and lowering sails. The former is likely to be more common in practice because of its simplicity and low cost.
The Roof Cover The roof cover is of smooth finish on the top surface, and channelled "capillary" structure on the underside. As an alternate, the underside can be of smooth hydrophobic materials to encourage droplet formation and rundown. The plastic of the roof structure is designed to be rip resistant, with an option for fibre reinforcement.
Plant derived fully bio-degradable plastics are desirable for this application.
In order to avoid overheating and excessive light levels, some degree of shade is applied within the plastic, giving the opportunity to incorporate a thin film photovoltaic layer within the plastic structure -reducing the amount of illumination going through the plastic and so shading the plants. Even at 5% conversion efficiency -conservative for current generation thin film technologies, this would give power output of up to around 1800 watts for a roof of 36 square meters and 3200 watts from a 64 square meter roof, which in many desert areas would result in the continuous equivalent power of around 500 to 1000 watts, more than would generally be used by a family in affluent Western nations. With the most energy efficient technology possible, at least 20 families could enjoy LED lighting, charge mobile phones, and listen to radio using the power from one Heliocycle roof, and quite likely have power left over to run a communal television. A Heliocycle can also be used to power mobile phone transmission equipment.
The Uprights These are vertical poles with "flagpole" pulley and tie arrangements to allow the roof to be easily raised and lowered by hand. The corner "flagpoles" are held vertical by a combination of part buried base, and guy ropes to ensure they remain vertical. GRP, bamboo, or other materials of similar properties can be used for these components.
Side Curtains Side curtains are fitted on one or more sides, with the orientation across the prevailing wind direction on the upwind side of the Heliocycle. In this way, the side curtains offer partial shelter to crops from the desiccating effects of dry winds, and be oriented to capture the most dew possible. For dew capture, a mesh structure is best, as it allows some wind to flow through whilst retaining a large surface area, so that the moment water droplets begin to condense in the air they are captured by the mesh, accumulate, and run down to a collection channel.
Components as per fig 1 & fig 2.
A. Shaded plastic canopy containing potassium iodide, photo-reactive shading, or translucent thin film photovoltaic material, with optional integrated cooling system.
B. Gutter to collect water condensed on the cover, similar gutter to collect water from side mesh Each gutter sloping to avoid standing water suitable for mosquito larvae and other nuisance waterbome pests.
C. Height adjustable mesh side screen.
D. Cable to raise and lower Heliocycle -allows cover to be dropped for extra protection against wind, or raised to work under.
E. Support pole -holds the roof assembly, gutters, and side mesh up.
F. Super-hydrophobic surface or capillary fluting to underside -to encourage condensation to collect and run down for collection.
G. Planting area below Heliocycle.
H. Gutter run off through flexible hose J. Potable water storage tank with filtered intake and cover to prevent the formation of conditions conducive to mosquito infestation.
