Filter idea- it is a good idea to have less polution but with some of the hazardous waste could be a potiential problem for this idea.  But still the disposal is a pitfall that needs to be considered. 

Hydrophobic computer casing-  it s a fantastic idea to protect your computer and seem like there is no pitfalls and they had a very great presentation.

Smaller gunpowder-it seems like a good idea but might seem to be more expensive then making just original gun powder.  it seems like a feasabile idea but seems the cost would overcome the benefit of it. 

Syring Innoculations-seems like idea is a good one but needs to find their idea for the patch.  seems like they dont know the application.  It seems feasible and the possiblility of it actually becoming a real thing is high.

Gecko application- it is a good idea but with the enviornmental aspects seems like it could be a potiential problem with the aspestous dust.  and regulation of this would have to be strict.  Some pitfalls of this idea is the enviornmental.

Nano tire tread- the treat is a good idea for protecting against hydroplaning and other enviornmental concerns.  the idea is feasible and seems like tire companys should look into this idea and figure out a way to do this.  I dont see too many pitfalls on this idea just maybe testing it more and seeing if the nano particles would erode out the rode faster.

Fheet- Fheet is something i would buy if i saw it i have poor circulation in my feet so looking over this presentation i see why i would like it.  it is feasible seem like there are some thing related to this idea so just expanding on their idea would work out well. 

Nano glasses-it is a good idea it helps people with anyone who is vision impaired but seems like the future is lazer eye surgery or fixing them.  But this idea is more feaible then lazer eye surgery for everyone.  Creation of the glasses would be one of the pitfalls and maybe the cost of such glasses would be tough.
