Designer's dream - CHEAP AIR TRAVEL

CHEAP AIR TRAVEL - Designer's dream
Why travel the conventional way, expensive, fast, hurried, full of hassels, and arrive at your destination, tired, behind time or ahead of your clock time ? 


The other way to travel is to CRUISE along in the air just like you criuse on the ocean waters in a gigantic ship. You guessed it right, I am hinting at the Air Ship. A helium filled gigantic air ship with modern technology to compress the gas at the press of a button to bring down the air ship on land, load her up, and to expand the helium gas for lift off and criuse away. 


The chambers for the passengers and crew would be totally seperate from the helium chambes, which could be located on the upper decks. The lower decks would house all the liveable quarters for the passengers, crew and their ammenities required for long travel times. 


If we can build and fly Dream liners weighing thousands of tonnes then slow moving feather light Air ships is a sure possibility too. 


It is proposed to accend to the height, just below the clouds to take advantage of the high winds in this region to move forward towards our destination. It is further suggested to take the help of the weather network to plan the flights / cruises so that we could take the maximum benefit from the freely blowing winds at no cost to us. 


Since the surface area of our Air ship is bound to be pretty large one, we must additionally plan for Solar power for on board needs & useage. 


Because the planet Earth is rotating in one particular direction - from west to east we must invariably plan for travel in the opposite direction and look for the winds which move from east to west to get additional advantage of the relative speeds: the Earth at 1000 km/hr. in one direction and the Air ship at maximum of 70km/hr in the other direction. We will get to our destination much faster and cheaper this way. I do realise that the power of gravity is always pushing us in the wrong direction, but at the cloud level its effect is mitigated to a large extent.

FOREST FIRES & LOGGING PATTERNS - DEFINITIVE CORRELATION



FOREST FIRES & LOGGING PATTERNS – DEFINITIVE CORRELATION



How we cut down our forests determines the probability of forest fires & their scale? You can have your CAKE and eat it too only if you have a fool proof plan. It all boils down to having your forest for eternity and zero / minimum forest fires during summers specially. 


NO THOUGHT TO PLANS


Big companies buy up gigantic pieces of prime forests and then leave it up the small time forest Rangers & supervisors to cut down trees, haul them up into large trucks, & transport the cut logs to the point of sale/auction. The average level of intelligence yields average results.


THE AVERAGE PLAN


Start from one end which happens to be closest to the main road and proceed to the other end if luck is on your side. Unfortunately, you never get to see the other end of the forest. Three or four seasons, all goes well and then suddenly there is a forest fire which burns down the whole forest to the ground.  


Big companies do not loose much in this deal because they had the forest insured against such a predictable calamity. The big losers are the Insurance companies and the common public who had their homes in the vicinity of this forest.


Recently we experienced such a loss of the whole township in Alberta Canada. Every year we hear & see hundreds of forest fires in rich states of California & other cities.





INTELLIGENT MASTER PLAN FOR LOGGING PATTERN  


It is a common sense approach to logging patterns which makes the total scheme of devouring the forest last for a long time till it is completely finished. No loss plan/approach.


MULTI PRONG ATTACK


If I owned a forest whose dimensions were 10 km X 10 km square, then the logging pattern would be as follows. Five gangs of men & equipment would start cutting down trees on one side of the square and another set of five gangs of men and equipment operate on the adjacent side of square. Each gang would be positioned at a distance of ONE km from the other gang. Thus we would be covering Five km of forest on each side of the square.


As the two sets of gang’s approach inwards towards each other in straight WIDE ROWS, we will be dividing our forest into beautiful manageable grids of one km X one km.  In the very first season we would be achieving 25 grids of one km square, each separated from the other by at least 100-meter-wide alley / space / road. These very pathways / roads will allow us an easy access right into the interior of our forest for fire fighting equipment if needed in future and minimize the damage by containing the fire to one such square/grid. The 100-meter-wide space between two plots of forest trees will be our added advantage in case of fire in one plot, even with high winds blowing the hot cinders away.  







BORROWING FROM COAL MINING TECHNOLOGY.


I have worked in under ground and open cast coal mines and it is no shame to borrow some of their ideas for the benefit of our forests. Once the coal has been evacuated from an under ground mine, it is mandatory to fill up the gap left behind, with sand. This process is called SAND STOWING.  Water and sand are mixed together and pumped into the mine to achieve the end result. In the same way we can pump up sand & water on to the 100-meter-wide pathways in our forest grids to achieve a fire proof alley between two plots of trees to prevent the fire from spreading from one plot to the other in case of fire and high winds. If my forest is full of costly teak trees then the additional cost of sand covering is worth it. The return on investment is very attractive.  


Once the complete forest is divided up into 0ne hundred, neat smaller squares of one km X one km, then and then only we can take a sigh of relief. Now we go ahead with logging pattern of widening the existing pathways and gradually reducing the forest squares to 0.75 km X 0.75 km. This strategy ensures that our forest will last us for a long time with minimum chance of burning down.



FORESTS ON HILLY TERRAIN


Different strategy is needed for a hilly terrain forest. Trees tend to fall/roll down from a higher level towards the valley of the terrain. Here we have to make similar pathways, but this time, RADIALLY from top to bottom to achieve the no loss / minimum loss result.
