The military IS the public sector. Most Public Sector/military advancements come ahead of the private sector because the private sector often has no need to replace certain goods/services. Additionally, alot of goods or services may be invented by the private sector, only to not go anywhere--the military or public sector picks up on them and develops them. ALmost all the things we have in modern society trace their roots to public sector/military/Nasa origins.
Historically, most of the advancements that have come to the public have been through military R&D. Some of the more notable military designs that came to the public were:
Canned food
(originally designed for the Indian wars--picked up by European armies)
Dehydrated food
(Initially the Brits, but picked up during WWI and WWII by the USA, then put into full gear by the space program/NASA ) Nasa IS military BTW)
Paper Dress patterns
(Prior to the mid-1800's dress patterns were cloth and bulky. To reduce shipping and to increase the ability to have reproducible designs, the British Commissary had paper designs created in thickend, durable paper)
The Computer
(designed to compute ballistic tables for the military--IBM refused to develope any computers until Univac began to make them for lucerative gov't contract--until the 1970's the biggest use of computers was for military and the military-industrial complex)
The Internet
(the original internet was ARCA net and was designed to share defense information)
Hypersonic flight
(for fast moving spy planes: ie: Aurora--hypesonic flight is cost-prohibitive for development outside of a military sphere because of the intricacies required for engineering safe transport of civillians)
Geopolymers
(for use by Engineer units in the field for constructing fortifications, etc)
Transistors
(Private sector invented this, but right after its invention, the USARMY and AIRFORCE requested miniturization of components in weapons systems)
Toilet Paper
(for obvious reasons)
Sprite Soda
( was designed uncarbonated to be a drinkable replacement for blood plasma in the 1950s/ 1960's. The Army rejected the product and the designer went on to create a soda from it. As an FYI, Sprite and DIET SPRITE ONLY have pretty much the same electrolyte composition as does blood plasma--diet sprite is a little bit better. I've used Diet Sprite in the field for soldiers who were injured or went down from heat and it picks them up--the only thing is that you can only use it in limited quantities)
SPAM
(though some people might not call this an achievement)
The source for this information are my handouts from my initial training I had in basic training and armypubs from my OBC in the late 1980's. There's alot more that can be directly traced tot he military
Project Mangement Theory
Gantt and Pert Charts were developed in response to the need for flexible means to ensure delivery of military products and also military units were properly supplied.

I want to know more about Sprite being used for blood plasma: http://www.answerbag.com/q_view.php/56418
