Machine for enhancing photosynthesis

Abstract

A method and apparatus for controlling light and temperature necessary for the optimum growth of vegetables and plants for backyard gardeners. This is achieved by using a photo-transforming membrane supported by a light-weight, luminescent, portable and easily-assembled without tools frame. The components of the apparatus can be efficiently and compactly packaged, suitable for mass distribution. The membrane has photo-transforming qualities which transform UV-light into a bandwith of light that promotes photosynthesis. This, in turn, enhances crop growth and increases internal ambient temperature.

Description

BACKGROUND OF THE INVENTION

This invention relates generally to the field of agriculture, and more particularly to a device for enhancing photosynthesis.

Recently, many public broadcasts have alarmed consumers about contaminated vegetables and fruits imported from countries which do not have to comply with our food content and contamination standards. This produce has led to localized outbreaks of food poisoning, particularly amongst grade school students.

SUMMARY OF THE INVENTION

Accordingly, it is an object of present invention to provide a device which avoids the disadvantages of the prior art.

In keeping with these objects, a device for enhancing photosynthesis is proposed which includes a additive-treated lens. This lens quantitatively converts and utilizes the previously unavailable and harmful portion of the light spectrum to amplify the benefits of photosynthesis for enhanced and accelerated plant growth and yield.

We intend to apply this recently-developed technology for agribusiness which satisfies the economies of scale necessary to produce the material at a cost-effective price for the homeowner. Therefore, we also feel that there exists, an as of yet, unrecognized market for a scaled-down, semi-mobile, homeowner-manageable, plant-growing appliance.

Some of the key considerations in addressing the above-mentioned challenges, were ease of erection, use, and aesthetics, as well as packaging, price, and market ecology.

Many popular home-oriented products purchased today require the end user to provide the final assembly, which particularly impacts packaging. We have, at this point, designed these products to include a maximum number of preassembled components to simplify assembly without increasing the bulk of the packaging. By configuring the initial offering into three functional and dimensional scales of complexity and size, we hope to be able to appeal to the dilettante as well as to the serious home gardener.

The structure, as presented, utilizes off-the-shelf components in order to reduce the capital investment cost of special tooling. In addition, it employs existing manufacturing technologies available in any third world country for optimal labor cost control. Moreover, the form of the support system can be enhanced using the luminescent covering of our proprietary product. As an added safety benefit, it will give its distinctive nocturnal glowing signature visible to all through its transparent skin.

The prototypes under initial consideration employ the traditional tunnel greenhouse shape. Nevertheless, the system permits other shapes as well, including the dome and the frame. Preliminary investigations indicate the feasibility of a balanced tension supported membrane as a second-generation offering. This suggests a minimalist three-dimensional sculptural geometry, such as hyperbolic parabloids, which would elevate its aesthetic integration of form and function.

We, therefore, are convinced that the growing, value-driven device will benefit and address the needs of every element in the production, marketing and final consumption chain.

In accordance with the present invention a device is proposed, which has a frame and a special membrane attached to the frame and converting harmful UV-light for plants or vegetables into growth-enhancing light that promotes photosynthesis. plastic, resin, tubular frame which is easily assembled without tools, lightweight, and portable in its unassembled or assembled form. In addition, the device reduces wind-resistance because of its airfoil design with valved panels. With the use of phosphorescent coating, the luminescent frame offers nocturnal safety. The device is supported by a water-ballasted structure stabilization which includes an integrated water-distribution irrigation system. This environmentally non-polluting growing appliance is covered by a fitted membrane, made of 6-10 mil polyethylene plastic. The membrane has photo-transforming qualities which convert harmful UV-light for plants and vegetables into growth-enhancing light that promotes photosynthesis. The fitted membrane is joined by heat-laminated seams over the frame, and is stabilized by 2 water-filled ballasted bladders. Each bladder has a filling and sealing fixture. One bladder is permanently affixed to the frame as a hinge, and the other bladder may be fastened to the frame at will for the purpose of stabilization. By transforming harmful UV-light for plants and vegetables, this growing device enhances crop growth. It extends the growing season, accelerates the ripening period by up to 3 weeks, increases the crop yield up to 50%, provides frost protection down to 18.degree. F., reduces the crop's sunburns and increases essential vitamins in fruits and vegetables. Finally, the growing device provides excellent durability increased freedom from maintenance.
