Important Removal Notes:- 

I have decided to remove all my writings under the title "3 ticking time bombs of the 21st century" including its sub-pages, namely "Political Religion", "Democracy" and "Nuclear Bomb", which have been appearing in this web section for many years. However, I shall only remove these pages before the end of this month (Nov 2011) in case some readers and friends might want to take a last glance. I had written those pages as a necessary reminder that we are all living in a great momentous time of history, called "The Aquarian Age". This Age was begun when our planet Earth's motion of wobble had caused the Vernal Equinox to move backwards with a rate of one degree per 72 years from the Constellation of Pisces to the Constellation of Aquarius, hence the change from the Piscean Age to the Aquarian Age! This new age has already brought new influence in the solar energy environment as well as new and rapid changes in social energies and developments on earth ever since roughly the 1830s. For instance, Michael Faraday started experiments on electricity around 1836, and today, our everyday life, in fact, every walk or activity of our modern life can do nothing without the use of electricity or electronics, and in all works or endeavours of modern science the energy of electromagnetism is involved. Please read the page 28) A few words on Aquarian Age

Therefore, the Aquarian Age is also an Age of Energy, or rather Electromagnetic Energy, because our entire world is now involved and engaged in the production of electromagnetic energy by converting it from oil, gas and nuclear energies, or from solar, wind and hydraulic powers. We can hardly walk, talk or think, not even argue or make wars without energy, or such converted  energies. It also means and shows that this is an Age of Science, of Invention, and therefore, also the Age of Great Revelation, because every single minute someone somewhere is inventing or revealing something new! There is a great tidal wave of Time, or of Age, or force of nature, rushing upon the living world like tsunamis! Any ineffective political rhetoric and system, in fact, anything old, rotten over time, especially old belief, which demands blind faith without proof, or science, logics or rationality, not even common sense, would be swept away in due time! ... So, in view of the present economic, political and social conditions with many years of unemployment, as well as the still possible conflicts or wars arising from great demands of energy, and also considering the momentum involved if and when great tsunamis should arrive, I have neither personal reasons, nor inclinations to be involved. So, I have decided to cancel my previous written reminders and warnings here and make my web writings purely accountable to science and cosmology only. 

 

In the meantime, since we are talking about energy conversion above, let me take this opportunity to suggest the following method of energy conversion from ocean tides (I have no idea if the method has been already deployed or not, although I did suggest the same method to a Chinese university a few years back!) It is a well known fact that the combined gravitation from the sun and the moon causes the tides in the ocean to rise and fall, giving two high tides and two low tides every day. The amplitude between the high and low level of tides depends on the geographic shape of the sea sides or bay sides in different places, because sea water can freely accumulate together to give much greater amplitudes depending on shape and sizes of geography, as well as the depth and amount of water. Although the average amplitude is only usually less than a meter, it is quite common to find places with tide amplitude of say 2 meters high. The largest known tides occur in the Bay of Fundy, where spring tidal ranges up to 15 meters have been measured. ..

 

It would be rather simple to allow, say 450 tons of water (450 cubic meters of water) or more to flow in and out of a container (say a square open tank of 15 meters x 15 meters x 2 meters) with an automatic timing device to open and close a simple valve at the base of tank in order to match automatically the timing of rising and falling of tides. Supposing the amplitude between two tide levels is 2 meters, then during the cycle from low tide to high tide, the rising tide would force the closed empty container to float upwards by 2 meters with 450 tons pressure, and then at high tide the valve would be opened to allow water filling the container before the valve is closed again. Meanwhile during the cycle from high tide to low tide the closed full container with 450 tons water would force the weight to sink 2 meters downwards, then the automatic timing device would open the valve to allow emptying the tank (by using small amount of air from beneath to float the tank and let water run out through the open valve, then close the valve when tank empties, so that the rising water pressure may force the closed empty tank to move upwards, and repeat the cycle). Thus, such a simple system would gain a total daily energy of  4 x 450 = 1800 tons of water weight moving through a distance of 2 meters. 

 

The energy from weight and motion of the tank may be connected by devices (cables, chains, gears, etc) and translated into angular momentum to drive an electrical generator and the resultant converted electrical energy may be stored in batteries. It is unlike solar or wind systems, which depend largely on changing availabilities of sunshine and winds. This system is simple, automatic, relatively constant, dependable, punctual and predictable in daily operation, and also relatively independent of ambient conditions. It costs little to build and is cheap to operate and maintain. Of course a larger numbers or sizes of such containers or tanks may be deployed depending on the geographical shape and characteristics of the place. Besides, tide amplitudes of less than 2 meters may also be used effectively...

Further note:- When I cancel out all the above mentioned pages towards end of this month, I will however keep the original part of writing, which describes how ancient Chinese rulers had taken great efforts and measures to create and maintain a truly democratic rule of the nation through fixed periods of nationwide written exams to qualify and certify every single high and low civil and military officers in the land (from Prime Ministers to village officers), thus giving truly equal chance to all able nationals in ancient time to participate in the government and the rule. The system is known as "Exam Raised" government, which had started well over 2000 years ago and was terminated only in 1906. I shall also try to improve the previous writings by giving more information and more details as well as conversion of dates and years to Western Calendar. (6th Nov 2011)
