Krowncha loha is described in "Mantra Sarvasva" as follows: Jyotirmukha or rose-coloured redwort 8 parts, tryambaka or copper 11 parts, humsa-tunda 12 parts, camphor 7 parts, tankana or borax 8 parts, sand 4 parts, choorna or lime 12 parts, owrwaara or cucumber?, ruruka 5 parts, patola or snake-gourd 27 parts, and vaardhyushika or sea-foam 1 part, these to be cleaned and placed in crucible, and heated in padma furnace to 512 degrees with 3 faced bellows, poured into churning yantra, and then cooled, will yield, a metal, honey-coloured, light, strong, rain-storm antidote, and heat-impregnated. Extracting oil from the seeds of basil, rukma or yellow thistle, punkha, red wort, trijataa or bael, and pancha-kantaki or 5 thorny trees, the metal should be smeared and heated. The metal is to be made into pattis with kuttinee yantra, make pipes out of them 3 feet wide of the same height as the vimaana, and fix them properly all around. In front of the vimaanaa-avarana also 3 feet high pipes should be fixed with keelakas or hinges. The pipes should be smeared with chana or gram decoction 1 inch thick. On that vajragarbha decoction or triangular spurge milk should be p. 119 smeared thrice, which will make it hard as diamond. On the pipes, at 12 inches intervals, sinjeeta vajra should be smeared and heated by fire. Then thumb-size panchaasya manis which will counteract the effects of water, should be imbedded on the smeared pipes.
Sooryaathapopasamhaara yantra or the burning-sun protection machine:
It is to be made out of the aathapaashana loha. It is explained in Kriyaasaara: Aatapaashana loha protects against burning sun. Therefore Aatapa samhaara yantra should be made with that metal.
"Lohatantra" describes that metal. Owrvaarika, kowshika, gaaruda, soubhadraka, chaandrika, sarpanetra, sringaataka, sowmyaka, chitraloha, vishvodara, panchamukha, virinchi, these twelve metals should be put in equal parts in padma-moosha crucible. Borax 7 parts, chowlika 5 parts, cowree salt 6 parts, kunjara 12 parts, sand 9 parts, camphor 4 parts, cardamom 16 parts, powshnika 10 parts, should be added to them, and placing it in nalikaa furnace heated to 725 degrees with mooshakaasya bhastrika bellows. Then the liquid should be put in, the mixing machine, and afterwards poured into the cooler. The resulting alloy will be light, orange coloured, heat proof, and unbreakable, for the making of sooryaathapopasamhaara yantra, after being duly purified, says Yantrasarvasva.
Kriyaasaara explains its purification:
Ashwaththa or sacred fig tree, mango, plantain, aala or banyan, baadava or peepul, trimukhee, trijata or bael, gunja or wild liquorice, sherinee, onurberah, patolika or snake gourd, the bark of these trees should be powdered, should be filled in vessel with 10 times as much water, and boiled down to one-tenth measure.
Then taking the 11 kinds of salts, bidaa-lavana or table-salt, syndhava or rock-salt, oushara or saline earth, budila salt, maacheepatra salt or p. 120 solanum indicum?, praanakshaara panchaka, or 5 urine salts or ammonium chloride? and saamudra or sea-salt, these eleven salts, should be placed in dravaakarshana yantra or dehydration machine and boiled. Taking the previous decoction, add half as much this decoction, put the aatapaashana metal in it and boil for 5 days, then wash with water, and anoint with honey, and place in hot sun for 3 days, then wash it, and use it for producing the yantra.
First pattikas should be made from the metal with kuttinee yantra, 2 feet square, or circle, and 3 feet thick. On that 3 pipes, 1 foot wide and 5 feet high, should be fixed. Three triangular glass bowls should be placed underneath the pipes. In each of them one prastha or seer of somadraavaka or white acacia juice should be filled. In each vessel a heat proof crystal of the 121st class should be cleaned with acid and placed. Then an umbrella shape 10 feet wide should be made out of the metal, and fixed so as to cover the 3 pipes, with revolving keelakas fixed halfa-foot underneath the umbrella cover. Above that 3 kalasas, 3 feet wide and shaped like cooking vessel, should be fixed. At their centre circular chaalapattikas should be fixed. Upon that three cold-diffusing crystals of the 185th number, should be fixed. On them three black mica wheels should be fixed. They should be covered with chandrikaa toolikaa or white silk cotton. On that should be placed a vessel with acid of manjoosha or madder root, in which a heat-resisting crystal is immersed. In the front part the toothed mica wheels fitted with bhraamanee-danda keelakas should be fixed. And in order to revolve that keelaka 3 wheeled keelaka should be fixed. By its motion the umbrella will revolve disturbing the heat wave. Then the heat-absorbing mica wheels will absorb the heat, which, pas-sing down to the madder-root acid, will become cold and get extinguished. And the crew and passengers will be saved from its evil effects.
The Third Floor:
In erecting the 3rd floor of the vimaana, the same procedure as was followed in erecting the second floor should be followed. Like the fixtures in the flooring of the 2nd aavarana and roofing of the 1st aavarana, fixtures should be put in connecting the roofing of the 2nd aavarana and the peetha of the 3rd aavarana. The peetha of the 3rd floor should be 5 feet less than the peetha of the 2nd floor, and be p. 121 square or circular like it. The cabins, doors, walls, and furniture on the 3rd floor should be on the same lines as in the 2nd floor. In the north eastern part of the 3rd floor, a cabin should be prepared for housing the electric generator. It should be made out of somaanka loha.
Somaanka loha is explained in "Lohatantra" as follows: Lead, panchaasya, and copper, 7 parts each, Chumbaka or loadstone 9 parts, nalikaa or Indian spikenard bark, sharaanika or rubus salt?, and borax, in equal parts, to be filled in sarpamukha crucible, and placed in naagakunda furnace, filled with coal, and heated to 353 degrees with shashamukha bellows. After melting the liquid should be filled in the mixer, and after churning be poured out to cool. The resulting metal will be a fine, light, electricity-impregnated somaanka loha. Out of that metal pattikas should be made with kuttinee yantra, or hammering yantra.
A cradle-like vessel, 3 feet wide and 8 feet high, should be made out of it, and be covered with a pattika with hinges. On the eastern and northern part of the cover two holes 1½ feet wide should be made. The cradle should be fixed in the electric cabin. Below the holes, two peethas should be fixed in the cradle. Two vessels 2 feet wide and 4 feet high should be prepared. Eight goblets 6 inches wide and 1 foot high should be made, and 4 each should be placed in the two vessels, in their four corners. In the middle of the 4 goblets, a big goblet should be placed so as to contact all the four. 2 vessels covered with patties having 5 holes should be placed inside the 2 holes in the cradle cover. Teethed churners 5 inches in size, 8 inches in height, like those of sugarcane machines, 8 in number, should be placed in the 8 goblets in the two vessels in the cradle. 2 churners, bigger than these should be placed in the two central goblets beneath the two holes.
Fixtures should be fixed on the central churner so that by their turning all the other churners will turn.
The procedure for extracting electricity out of solar rays is as follows. 8 naalas or tubes should be prepared out of the 192nd kind of amshupa glass. The naalas should be fixed on the 4 corners of each vessel. Panchamukhi karnikaas should be placed on them, filled with rukmapunkhaa shana, and with electric crystals in them. Covering them p. 122 with the amshupaa glass cover, 5 spires should be formed on it. The top of each spire should be like an open beak, and in it should be inserted sinjeeraka crystal and amshupaa crystal. On the central spire amshu-mitra mani should be fixed. Above the 4 crystals should be fixed 4 glass tubes made of kiranaakarshana glass, 6 inches wide and 3 feet high. On them should be carefully fixed 4 feet-wide-mouthed vessels, acid cleaned. They should be filled with Rudrajataa-vaala or aristolochia indica linn. Revolving ghutikas should be placed in their centre. The ghutikaas will attract the solar rays and send them through the tubes. The crystals in the spire beaks will suck them in. So does the shinjeera crystal inside, as also the amshu-mitra crystal. The power will be absorbed by the glass-covering, and sent to the electric crystal. Then the karnikas inside will receive it and send down to the central tube with force. When the central churner revolves the other churners also revolve. The power will enter the acid, and the crystals in it will whirl with great speed, intensifying the power force to the extent of 1080 linkas. That force should be collected by the ganapa-yantra in front of the cradle, and stored in the central storage.
The Ganapa-yantra is a machine shaped like Vighneshwara, 1 foot broad, and 3 feet high. From its head a tubular projection like Vighneshwara elephant's trunk, covered with glass and with wires inside should be fixed at the front of the cradle, and connected to the Ganapa image from the neck to the navel. Three-inch toothed wheels should be so fixed that a big wheel at the neck of the image, by force of the current coming through the trunk or proboscis will whirl, setting the other wheels in motion. A coil of wire should be placed in the centre. On it a sapta-shashthi shankha or conch called simhikaa should be placed, with covering made of kravyaada metal. 5 spoonfuls of jeevaavaka acid (ditamine?) should be filled in the conch, and 217 p. 123 bhaamukha graamukha manis or beads should be placed inside. 5 umbrellas, 2 inches wide, should be made, and 5 sun-crystals of the size of big liquorice, should be stuck on them. The umbrellas should be fixed on the conch, with amshupa glass covering. This should attract the force of the sun rays, and pass to the crystals on the umbrellas, making the crystals and the umbrellas whirl with fierce force of 1000 linkas, and the force passing to the acid in the conch and the crystal inside, will thence pass westwards, and could be transmitted through wires for any desired use. To measure its exact force a meter should be fixed in, along with thermometer and other needful equipments.
When the vimaana has to move on the ground, the electric current is switched on the electric motor in the hub of each wheel, thus causing the rim to revolve and move the vimaana.
But when entering water the wheels are drawn in by the movements of toothed segment and the pinion, the latter being revolved by an electric motor attached to the shaft. The openings in the bottom of the vimaana are closed by the sliding covers moved by the rack and pinion arrangement, the pinion being worked by an electric motor.
The movements of the hinged joints of the folding links will raise or lower the second floor over the first floor.
ELECTRIC GENERATORTwo jars are placed on the peetha or stand. Each jar contains five cups filled with acids. Each cup has a churning rod with gear-wheels connected together. The wheels are revolved by hand while starting, and by the generated electric power afterwards. A darpana or mirror and gharshana manis are fixed above the gear wheels. The darpana and the manis absorb the sun's energy and transmit it to the acid cups. The acids, being churned, convert the absorbed energy into electric current, which will pass through the pancha-mukhee naala, or five-way-switch, to different points, and work the machines there.
THE ELECTRIC MOTOR
The electric motor consists of a loop of fine wire coil, with a fine wire cage in the centre. The current from the generator is brought to the wire coil through a glass tube. Suitable wheels are attached to the wire cage to connect to the churning gears of the generator or the shaft of the pinion.
The Simhika shankha on the top of the motor contains an acid and the bhaamukha-graahinee mani or crystal. Five rods with amshupaamitra manis are fitted to the top of the shankha, and toothed wheels are fitted to these rods to revolve together and rub against the inner surface of amshupaa mirror at the top. The solar power absorbed by the mirror is stored in the shankha, and given out by the bhaamukha graahinee mani to the various motors in the vimaana.
