Looking at the list:

* Cotton Picker - didn't get done in Edison's time, done in mid 20th century

* New Standard Phonograph, Hand turning phonograph - product improvements

* New Slow speed cheap Dynamo - ?

* New Expansion Pyromagnetic Dynamo - ?

* Deaf Apparatus - hearing aid. Edison never developed a good amplifier

* Electrical Piano - also needed an amp, (but see Teleharmonium)

* Long distance standard Telephone Transmitter which employs devices of recording phonogh - something else that needed an amp

* Telephone Coil of Fe [iron] by tt in Parafine or other insulator - loading coil?

* Platina Point Trans using new phono Recorder devices - point-contact microphone, a dead end.

* Grid Battery for Telephones, etc. - a battery improvement

* Improved Magnetic Bridge for practical work - something to replace the Wheatstone bridge and mirror galvanometer, a sensitive but un-amplified lab instrument. Again, if only he'd had an amp...

* Motograph Mirror, relay, Relay, Telephone practical - the motograph was a really clunky way to amplify, using an unusual physical effect where the friction between a rotating chalk cylinder and a contact changes with the current through the contact. Dead end, although the phenomenon was used once in an IBM line printer paper drive clutch.

* Artificial Cable - ?

* Phono motor to work on 100 volt ckts - routine job

* Duplicating Phono Cylinders - the Edison Amberoll process; many playable cylinders still exist.

* Deposit in vacuo on lace, gold + silver also on cotton molten chemical compound of lustrous surfaces to imitate silk— also reg plating system - ?

* Vacuous Ore milling Large Machine, Magnetic Separator Large, Locking material for Iron sand - part of Edison's cement and rock crushing period

* Artificial Silk, Artificial filaments - trying to find something better for incandescent lamps, pre-tungsten

* Uninflammable Insulating Material - General Electric Deltabeston felted asbestos insulation - "Will not age or crack". Worked great, except for the asbestos hazard

* Good wax for phonograph - he did that

* Phonographic Clock - "speaking clock - was done eventually, but not by Edison

* Large Phonograph for Novels, etc. - long-playing records, not in Edison's time

* Pig Iron Expmts with Electricity + Magnetism, Malleablizing Cast now in Vacuo - ?

* Drawing fine wire - figuring out how to draw tungsten wire for lamps was really tough, but GE eventually did it. Edison not involved

* Joy phonograph for Dolls - somebody did that in Edison's time. Mass produced as Mattel's Chatty Cathy in the 1950s.

* Cable Motograph, Very Loud Motograph telephone with 1/3 siz phonogh motor. - more attempts to amplify

* Magneto telephone with actual contact end magnet compression of an adjustable rubber press as in new phones - ?

* Snow Compressor - ??

* Glass plate water ore repeator - ??

* Tinned faced [illeg.] for Stove Castings - somebody did that, old stoves often have tin facings

* Refining Copper Electrically - somebody did that too, but not Edison

* Quad neutral relay - another multiplex telgraphy component

* Cheap low induct Cop Insulating material for Lead Cable people - insulating materials were a big problem in Edison's day. No plastic, no synthetic rubber. Lots of wood, fabric, paper, tar, etc., all bad.

* 200 volt 20 cp lamp - another size of light bulb

* Recording Volt Indicator - done, but not by Edison

* Box balancing System - ?

* Alternating Machine + Transformer - Tesla's department

* Platinum wire [illeg.] cutting Machine, silver wire wood cutting system - hot wire cutting? Dead end for wood, although today we have laser cutters.

* Boron fil. - Boron filaments didn't happen

* Hg [mercury] out of Lamp - beginnings of environmentalism?

* Phonaplex Repeater - another problem that needed an amp.

* Squirting glass sheet tube etc. Nickel [illeg.] - glass extrusion worked fine, but Edison didn't invent it

* Artificial Mother Pearl - too early for plastics

* Red Lead pencils equal to graphite, India Ink, Tracing Cloth - shopping list?

* Ink for blind - not by Edison

* Fluffy Incandescent Burner for gas - lantern mantle. Done, but by Edison?

* Regenerative Kerosene Burner - ?

* Centralized arc in arc Lamp, Cai–[illeg.] Tesla arc lamp test - ?

* Strengthening alternating cli by sternt Dynamo - ?

* Electroplating Machines for Schenectady - OK, must do day job

* Condenser Transformer - a charge pump? Common today in IC size

* Sqr ft diffraction gratings in silver by 5000 [illeg.] tool special [illeg.] lathe for ornamental purposes - popular with hippies in the 1960s

* Cheap plan produce Mimeograph surfaces - Edison mimeograph upgrade?

* Miners battery + lamp - good product idea, done by many

* Sorting Coal from Slate Machine - mechanize a job done by kids. Coal floats, slate doesn't, and coal breakers exploit this.

* Butter direct from Milk - ?

* Burning asphalt Candles by high chimney - bad idea

* Magnets RR signals - ?

* Soften [illeg.] of books transfer to Cop plate + plate to [illeg.] matrix - ?

* Telephone Repeater - another need for an amp

* Substitute for Hard rubber - not really solved until neoprene in WWII

* Artificial Ivory - ABS plastic was a long way off

* Revolving Thermo - ?

* Caller Indicator for Jump Telegh - ?

* Marine Telegraphy - undersea cable, or ship to shore?

* Long distance speaking tube filled H20 2 dia pressure - dead end

* Lend plate battery for modifying attending Current - ?

* Two revolving bands in battery Lead faced press in liquid close together + out into separate chambers to [illeg.]reduce by gas the other - ?

* Siren phonogh - another need for an amp

* Perm mag like an electromag of [illeg.] hand steel high polish separately magnetized + forced together powerfully[illeg.] - magnetic materials in Edison's day were weak by modern standards. If he'd tried adding some cobalt...

* Telephone working more [illeg.] - yes, focus on day job

* Eartubes formed crescent [illeg.] wire - ?

* Cheap Voltmeter - outsource to New Jersey?

* Chalk Battery - dead end

* Dynamo or motor long tube in long magnetic field top + bottom contacts forcing water through generator current by – passage.
[Illeg.] - the beginnings of magnetohydrodynamics?

* Thermo battery slick Copper oxidized then plated over surface oxide nailed to make good contact [illeg.] - ?

* Disk Phonograph - that worked out very well
