This is not an exhaustive list, nor does it include the various inconsistencies with periods at the end of descriptions or seemingly random capitalization.

Tech Typos:
ALL Hull sizes - "Full Description Goes Here"
ALL mining starbase improvements - "Boost yields of attached Recourses" - should be "Resources"
AntiMatter Extractor - "Boost yields of attached Anti-Mater Recourses" - should be "Anti-Matter" (or in keeping with format, "AntiMatter")
Elerium Extractor - "Boost yields of attached Elierium Recourses" - should be "Elerium"
Quantum Research Foundation - Text clipping in title field only - this is a very long name
Universal Integrity Filed AND Universal Displacement Filed - should be "Field"
Universal Displacement Filed - "...reduces the logistics cost of a shop." - should be "...of a ship"
Colonization Focus and Biosphere Perfection (all sub-entries) - "Normalizes...  and boost" - should say "normalize and boost" or "normalizes and boosts"
Targeting Array - "...of all ship in fleet" - should be "all ships"
Guardian Drones Module - "small but Tuff" - should be "tough"
Shield Leach - should be leech
Plasma Turrets - "Adds Plasma Torrents" - probably should be "Turrets"
Beam Magnification Array - "...of all ship in fleet." - should be "all ships"
Missile Guidance Array - "...by all Missile Weapon in fleet." - should be "Missile Weapons"
Accelerator - "Adds a Graviton Accelerator." - mismatch, either the name of the component or the description.
Phasors Pod (or Phaser Array) - probably should be "Phasers" unless there's a good reason to call them "Phasors"
Photon Launchers - "Adds a Photon Torpedo Launcher." - probably should name the component "Photon Torpedo Launcher"
Nightmare Torpedoes - "Increase Missile Attack, High Damage and
Long
range with good accuracy, but slow rate of fire." - spare line break, or early clipping error there
Quantum Drivers - "...of devestating kinetic weapons." - should be "devastating"
Defense Network AND Sector Defense Grid- "...of all near bay ships" - should be "near by"
Point Defense Specialization reduces Point Defense Cost instead of increasing strength (or at least that's what the tooltip says)
Missile Disruptor - "...defense system the protects entire fleet." - should be "that protects"
Leaching Field - should be "Leeching Field"
Aereon Missile Defense - or Arreon Missile Defense (tech and component) - I think this one should be Aereon
ALL cultural starbase improvements - "Helps extend the your Cultural Influence" - should be just "extend your"
ALL governments - "allows use of XXX form of government" - should be "use of the XXX form"
Promethion Pleasure Park - "Greatly Increases the Moral of a Colony,..." - should be "Morale"
Economic Efficiency - no icon to indicate this allows construction of Efficiency Center
Easley Distracted - should be "Easily"
Zero G Arena - "Boosts theApproval" - should be "the Approval" (space added)

Yor-specific typos (I think):
Power Matrix - extra comma after race; last words currently "power always needed" - should be "power is always needed"
Manufacturing Focus - "...if they understood how great our production capacity." - should end with "is."
Fusion Matrix - "allows creation of Fusion Matrix" should be "the Fusion Matrix"
