In today’s world we give more importance for time than anything. If you travel from new york to los angeles by plane it takes 6 hrs to cover 3950 km distance. If we develop faster mode of transportation we can reach in 31.5 mins at an average speed of 8350 km/hr.We wonder how it is possible? but it is possible in the future. This system is called “planetarium”. A magnetically suspended tram moving through a pipeline at a low pressure. The thrust is generated by the pressure difference at the other end of vehicle. The tube inside which the vehicle moves is sectioned into locked compartments, all the compartments are at a different pressure so that pressure falls in the outward direction. These pressure drops propel the vehicle until compartment no. 50 for example. The pressure is only 98 pa. which corresponds to atmospheric pressure at an altitude of 50 km. Thus fairly low pressure is established for the remaining length of tube & the accelerated vehicle pierces at an enourmous speed. When the vehicle is on way back, the pressure settings are obviously reversed. The acceleration down the initial section is limited by passenger comfort. The contraction of such a system is an extremely involved energetic challenge. The most challenging problem is the concentration of the scheduled large diameter pipeline extending for a greater distance. This is possible for the oil & gas transportation. The construction of tube carrying wheel less vehicles at the space speeds may be possible tomorrow.

Military Communication
The world of communication made the world as a global villege. Most of the communication developed for the purpose of Military usage in the world war 2. The advanced radio design development & production in frequency from 1.5 mhz to 5 Ghz. It features high speed built in crypto algorithm. Cryptology is the study of military codes. Written in theirion military codes and electronic counter measure techniques.
1) Frequency hopping
2) Direct response
For reliable communication under severe battle environment. Quality modems to serve the increasing demand for command, communication, control, computer, intelligence, survelliance and reconnaisance. (C4ISR). Multichannel line of sight frequency hopping wide band radio equipment. for reliable inter command parts communication.
Tactical Terminals- Computers & communication controllers from HQ to any point in the battle space.

Solar Flares and its Effects
Solar Flare is a violent explosion in the Suns atmosphere releasing upto a total energy of 6×1029 joules. Solar flares takes place in the solar sun layer of corona 7 chromosphere heating plasma to tens of millions of kelvins & accelerating electron protons and heavier ions to the speed of light. They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from the long longwave radio to the shortest wavelength gammarays. Most flares occur in the active regions around sunspots where intense magnetic fields emerge from the suns surface into the corona flares are powered by the sudden release of magnetic energy stored in the corona. Solar flares were first observed on the sun in 1859.

Building Things in the Nano Technology
All the products around us are made of Atoms. The properties of these products depend upon how their atoms are arranged. By rearranging atoms in coal, we can make diamond & by rearraning in sand & adding a few other trace elements we can make computer chips. Todays manufactureing methods are crude at the molecular level. Coating, grinding has led to the tools capable of manipulating individual atoms. Nano technology the shortgun marriage of chemistry & engineering is in the era of
1) Self replicating machinary
2) Self assembling consumer goods
Made from cheap raw atoms by using the well understood chemical properties of atoms & molecules. It proposes the construction of nove molecular devices with extraordinary properties. The trick is to manipulate atoms individually & place them exactly to pro1!duce desired structure.
1) Computers billions of times faster
2) safe space travel
3) No more pollution & automatic cleaning of existing pollution
4) Molecular food synthesis to end famine
5) Re introduction of extinct plants & animals
