Conceivable Applications

1) Food transport
Food (fruits, vegetables, seafood, etc.) is kept fresh for longer periods and free from contamination. This allows consumers access to fresh food, regardless of the distance and time covered from the production area to the consumer.

2) Medical Transport
Temperature control (without using electricity) during the transportation of medicine keeps it safe from deterioration.
This is an extremely important aspect of the system, especially in hot climates where efficient transportation is not really affordable.

Competitive Advantage

There is no competition in the market we know of.
Current methods include either using a refrigerator van for transportation or processing the food in specialized factories before transporting it.
New users of our system are shifting from the two abovementioned methods to the Dream Box.

●Cost
1) Layers with minimal thickness are based on cutting-edge nanotechnology.
Only a few materials are required to keep the cost low.

2) All the coatings are water-based. There are no solvents.
There is no need for a special room in which to apply the coatings.
These products are categorized as nondangerous substances, making the exporting and importing costs very low.

3) Only an ordinary foam box is required.
Local production is easy.

4) Lightweight
Coatings are thin and light to match the advantages of a foam box.

5) There is no need to install electricity to maintain the temperature.

●Durability
The layers are all inorganic, and performance will remain intact unless physical damage occurs to the construction.

●Environmentally friendly
Since no electricity is required and less energy is used to keep the contents fresh or cool, the emission of greenhouse gases can be reduced dramatically.

Performance

The example for food transport shows here a definite advantage in the length of cooling time that keeps food fresh. Whereas current systems dramatically “heat up” after 15 hours, our proposed “Dream Box” system “keeps cool” for as long as 48 hours.

Four unique main features:

1) Antimicrobial contamination and antipollution (outside)
An antistatic function repels dirt from the surface, and the catalytic effect destroys microorganisms.

2) Thermal insulation and protection against (infrared) sun rays (outside)
Reflects sun rays and prevents the temperature from increasing in the box

3) Ethylene gas absorption and thermal insulation (inside)
Ethylene gas is quickly absorbed to prevent food from deteriorating.
An inner insulation layer provides extra thermal control.

4) Ethylene gas breakdown and antimicrobial contamination.
Destroys the ethylene gas that causes food deterioration, and prevents the growth of microorganisms that otherwise would grow inside the box and on the food.

As a result, food is kept fresh and transported for long distances with no need for cooling by electricity.

Technical maturity / Past record of introduction

For example, one of the technologies featured in the Dream Box, the ethylene gas control system, is presently in commercial use by WIZ FRESHTEK Co., Ltd. in Korea, to supply more than 600 accounts, including agricultural associations, agricultural cooperatives, and private farms. (Ethylene gas absorption and breakdown packs 1,000pcs per month)

Another popular product on the market now is the photocatalytic antimold film made by Sansinsya Printing Co., Ltd in Japan.
This new coated film can be used to make instant clean rooms, allow for safe food packaging, and consequently secure surface and environmental protection in transportation and other various fields, as well.
Also, this film is disposable. This means contamination can be tightly controlled.
 (Quantities of 200 to 600 rolls are marketed monthly. Roll size: width 1m, length 200m)

Modality of business transaction

Partnership
Form a cooperation agreement with a local partner in the country where the patent will be issued. This will allow for a gradual transfer of the technologies used and will eventually lead to local manufacturing. The first step will be based on the export of ready-made products, to be followed by maintenance know-how guidance and local production ability.
