- Reasons against an Alternate Current Converter system-- Danger 1st The pressuer on the high tension mains are destructive of life-- 2nd Running high pressure mains into stores & houses to connect to converters is dangerous to life-- 2rd Converters act as Condensers and notwithstanding two systems ie high and low are not electrically connected one may get a several thousand volt discharge under certain [constitious?] between low tension system and the ground 4 Impossible without danger of repairing high line when current on 5 Disruptive action of reverse currents require heavy insulation 6---- 7 to get same economy of conductors the greatest dfference of potential on high line & ditto low line must be 3 times greater than with continuous currents. to do what 2000 volts continuous will do difference of potential of at least 5000 volts must be used-- If on the low line 2 wire distribitution system is used & 100 volt lamp then 140 mean must be used or diference of potential of 280 volts alternated current If three wire system 560 volts diference potential & this is fatal-- Continuous currents polarize the points where the current enters the body & prevent its passage-- There is no polarization with alternated currents hence full current passes & kills 8-- As Alternate Current machines must be worked with continuous or constant field not derived from the main suply circuit, any shortcircuiting of line must burn out machine as it is not saved as in Continuous Current system 8 The doing away with commutators on Continuous Current machine is no gain as there must be a field energizing dynamo or section on the Alternate Machine & this must have a brush commutator Experience has shown that small machines spark worse & give more trouble than big machines-- Preceding this and needing to be individually indexed as N321167 are the following notes: 1st The sun is a solid globe of molten matter revolving on its axis once in [25+?] days 2 A powerful electric current circulates around the whole of its body from west to east parallel with its equator and to the poles. 3 This Electric current is sufficiently strong to keep all its matter except at the poles and center at vivid incandescence 4 Lines of force pass through its body in the same manner as a cylincer of wire wound so the wire would be in the same direction as the currents circulating in the incandescent matter. [overstruck text] half of these lines pass through the sun the other through space from pole to pole forming a vortex 5-- Excentrically of the lines of force due to the attraction of the sum total of the lines of force of all the plan[e]ts & starts causes the sun in its rotatio to cut its own lines of unequal strength & thus produe its current, & heat. 6 planets are held in their orbit & propelled by the mutual attraction of closed circuit currents 7 Except the shell all planets are matter & conduct electricity 8 The lines of force weaken as they recede from the sun at the square of the distance hence The 1/2 of the planet nearest the sun passes through the lines of force stronger than the 1/2 furthest from the sun This difference produces powerful currents in the molten matter & causes the rotation of the body on its own axis. 9-- These currents cause lines of force to proceed out of the planet and produce a field disymetrical with the axis so the magnetic poles are never the astronomical poles 10 This system shifts at every revolution ofhte planet hence there must be a diurnal variation of the needle, & since the axis shifts there must be an annual, & since the symetry of the lines of force are disturbed by planetary conjunction there must be secular variation. 11. One 1/2 of the planet is powerful electrified N & the other S. passing through the lines of force The poles of wich are in the equatorial regions-- The signs should change once in 24 hours and have 2 max & 2 minimum in potential for the Earth. 12 Matter in vacuo or space conducts electricity like a metal between an incandescent substance like the sun and other incandescent matter as or cold conductor as proved by the centre wire in filament lamps. 13 gravitational attraction has not existence but all weights are due to static or current attraction. 14 Lines of force proceeding from the N pole of the sun to the south pass along the circumference and by curved lines outwardly to unlimited space; The Body of lines of a 1/2 section of the ring of the vortex is the line of balance magnetir or conducting matter on this line is neither attracted or repelled by the sun if any conducting matter having a current in it or electrified is in space between this line & the sun it will be repellled if on the other side, attracted 15-- Sun spots are due to faults in the molten surface of the sun an electric arc forms across the fault the two side will have the current & diminish in temperature & appear dark by comparison. The arc being mobile & conveying a current will be attracted outwardly to the center of strength of the lines of force just as an ordinary Electric Arc tends to go to the Center of the L of F of a magnet. The arc breaks long before it reaches this point hence the incandescent matter surrounding the sun-- 16 prominent are arcs of small difference of potential but with great current strength due to great mass of matter 17 The tails of comets are due to the breaking of the arcs from repellent action as the[y] approach the sun 18 Difference in Conducting power of diferent planets instead of the specific gravity must be correct. 19 All planets were once projected from the sun by faults inthe equatorial strata. The region from which they were projected was at dif temperature verlocity & the matter must have been necessarily different. The moment the general current of the sun ceased to pass through the detached matter attraction nearly ceased [overstruck text] & it was thrown out into space where getting a rotary motion adopted a very eccentric orbit & rotated on its axis & finally the eccentricity diminished & it took the regular orbit 19-- Comets are matter recently thrown from the sun The reason comet can never fall in the sun is that they have powerful currents in them & if they pass Mercury towards the sun they pass the line of no attraction to the line of the repellent so periodically of sun spots is produced by shifting farther from the sun the neutral on non attractive center of L of F by approach of Jupiter or other planetary [long----? can't read word]. more powerful attraction of the arcs causes many to break & thus produce a disarrangement of the equivalent surface dminishing great number small arcs & creating few large arcs & consequently spots by comparison & by depriving the poles or edges of faults of current by conduction
