The present invention is directed to a passive solar greenhouse for controlling the greenhouse's interior environment and maximizing photosynthetic metabolism within the plants grown therein through regulation of sunlight, temperature, humidity, and carbon dioxide levels and methods optimizing plant growth conditions by using passive solar greenhouse of the present invention. Generally the greenhouse has a sloped glazed face which faces substantially true south in the Northern hemisphere and substantially true north in the Southern hemisphere with a predetermined slope angle designed to maximize incident solar radiation (insolation) and increase the interior temperature during the colder months of the year while reducing overheating during the warmer months of the year.

In general, a constellation of spacecraft is used to broadcast to a particular region with high angles of view in order to reduce blockage or shadowing. A constellation of a plurality of spacecraft is placed in 24-hour orbits having inclination of about 550, eccentricity of about 0.32, semi-major axis of about 42,000 km, longitude of the ascending node of about 43° East, argument of perigee of about 270°, and longitude of the ground track at maximum latitude of about 7° East. The preferred number of spacecraft ranges from three to six. In a particular application of Digital Audio Broadcast to Europe in some embodiments, the most populous cities are provided with service from no more than about 10° from vertical, and broadcast takes place when the spacecraft are above at least 35° North latitude. The broadcast power is reduced during those portions of the orbit in which the ground track lies in the Southern hemisphere. (146)

Provided is the moon phase display mechanism to reflect the moon phase difference in vision between the northern and the southern hemisphere of the earth. This invention relates to the moon phase display mechanism that displays the moon phase.The moon phase mechanism consists of two discs ; the top disc (1) called moon dial and the bottom disc (2) called moon display part which are attached concentrically and rotatably each other. The moon dial (1) has two apertures (1a and 1b) so as to reflect the moon phase difference in vision between the northern and the southern hemisphere of the earth.

The invention discloses an accurate steering adjustment method for a photovoltaic solar panel, which comprises the steps of (a) acquiring latitude and longitude coordinate information and current day data information; (b) acquiring local sunrise time and sunset time of the current day according to the latitude and longitude coordinate information and the data information; (c) calculating the time difference between sunrise and sunset according to the sunrise time and the sunset time; (d) acquiring the average angular velocity Y of the sun between sunrise and sunset; (e) enabling the photovoltaic solar panel to face towards the due east, timing from the sunrise time, rotating the angle of the photovoltaic solar panel every 15 minutes with the rotation amplitude being 15*Y at each time, wherein the photovoltaic solar panel rotates clockwise along the horizontal direction if the photovoltaic solar panel is located in the northern hemisphere, and the photovoltaic solar panel rotates anticlockwise along the horizontal direction if the photovoltaic solar panel is located in the southern hemisphere. The method disclosed by the invention is used for solving a problem in the prior art that the orientation of the photovoltaic solar panel is inconvenient to be adjusted, and a purpose of carrying out accurate control on angle adjustment of the photovoltaic solar panel is realized according to local specific sunlight conditions.
