The Solar Hot Plate and the Solar Lamp

Among the advantages that phosphorescent medium has over silicon semiconductors as a solar energy source is that the phosphorescent medium is a natural solar collector, a type of big sponge that soaks up solar energy with relative ease, and the phosphorescent medium also incorporates its own battery and so could function as a storage medium for energy as well, whereas with silicon you would require a separate battery or otherwise you would be restricted to using the energy produced by the silicon device only 'on demand' and then only when time and day and weather permitted.

The advantage of silicon is that when you want a charged electron you can get a charged electron and that is not going to be a really big problem. With the phosphorescent medium you pretty much have to resort to an armed robbery and an assualt so as to rob that phosphorescent atom of an electron at gun point if a charged electron was what you wanted.

However sometimes you want to feud and fight with a phosphorescent medium while at other times you might want to adopt a more cooperative approach. There are times when a photon might come in handy.

One example of this would be the solar lamp. The lamp charges up during daylight hours and then releases its photons to provide light at night. The solar lamp would be a device which could depend upon doping in order to function, since we know that doping can increase the battery life and prolong the release. We also know that doping results in red, green, and blue phosphorescence, and as you know when you look at a television screen or a computer monitor (RGB or 'red green blue' devices) you can make any color, including white light, by combining red, green and blue. We can therefore picture the solar lamp as being composed of long lasting, slow release doped phosphorescent material. It is at this point that we need to consider emulating the silicon solar collector and we have to consider perhaps an 'NPN' or "PNP' type of arrangement. Here I am picturing in my mind the way that in a silicon type solar cell can have the charge carriers separated by employing layers of material with different electrical properties. The purpose would be to once again emulate the way a plant employs a type of cascade effect to move an electrical charge away from the surface and into storage down below so as to keep the surface area free and ready to collect more photons. I am also assuming that it would be possible to create this type of leaky battery using only doped phosphorescent materials and the correct circuit arrangement of layers of material, which would simplify the device and exclude such elements as magnetics and resonating circuits, since we are now cooperating with the phosphorescent material and are willing to accept a photon as an output. Along with this idea we can also think about incorporating a switch (on / off) since the device begins to resemble a transistor of sorts.

A second device we can imagine constructing would be the 'solar hot plate'. Keep in mind that one of the big reasons that trees get chopped down by the populations in poorer areas of the world is meet energy requirements, and then because the watershed is destroyed over time, this then results in floods when it rains and the washing away of valuable soils and so on. A solar hot plate would also rely upon the release of photons, and in this case we would have to imagine a device engineered to release infrared, or we could imagine including in our design a substance that when bombarded with photons reacts by heating up. One possible design concept that has occurred to me is that the hot plate element would function as a type of solar collector, heating up when placed in the sun. Now below this plate and enclosed in a container would be hidden our phosphorescent based storage battery, for some of the heat collected by the hot plate would radiate downwards from the bottom of the heated plate into the container. At this point we have to imagine that we have a phosphorescent collector which is sensitive to infrared radiation. Therefore the device becomes like a heat sink and later on when it is 'turned on' it begins to release the stored energy in the form of infrared radiation, heating the cooking plate from the bottom up.
