I've made a couple of minor grammatical tweaks/suggestions in green below...

Folding at Home Proposal by Alex Share
I first started using folding at home on my personal computers back in my freshman year of high school (2005-06) and have been actively participating in this program over the years. The idea of this application was conceived at Stanford University by a group of computer enthusiasts looking for way to put their computers to good use when they were idling. What better thing could
one do with
their computer than to try and solve problems that, until folding at home
's creation, would have been thought to be impossible
?
Currently worldwide there are just over 250 Thousand computers going through the extremely complex job of what we call
"folding" proteins. Proteins are biology's workhorses
; they are microscopic machines that carry out very specific jobs in all living things. But before they can do their jobs, they must first build themselves, or
fold. What this program does is simulate the infinite ways that all the many different proteins might fold and the
potential outcomes. By doing this
, we hope to find cures to many illnesses that we, at the moment, cannot solve
. Some examples include: Alzheimer's, Huntington's, Parkinson's disease
, and many of the cancers.
You may be thinking,
"what do proteins have to do with these sicknesses?
" Well, the reason that these illnesses occur in our bodies is because of protein
misfolding. When proteins do not assemble properly
, they cannot carry out their jobs and the body will malfunction.
Folding
at Home has been around for
eight years now and it has managed to acquire
roughly 35,000 more contributors each year. This program is available for
both PC and Mac computers and will not hinder their performance in any way
. The application will only use system resources and computing power when there is no other process demanding anything. The
Folding at
Home application is at the bottom of the priority list as far as allocating system resources is concerned.
______________________
Some of the suggestions that I made were not so much corrections as just ways to ensure that your sentence structure was as strong as possible. Others were grammatical corrections or just tweaks for consistency (for instance, you labeled the app "Folding at Home" at the top, but later called it "Folding @ Home" and also used it without capitalization...it's always best to choose a format and stick with it).
I hope this helps you out. Your content is very good. I might also suggest, however, that you add a summary paragraph alongs the lines of "it is for this reason that I believe yadda yadda yadda yadda." You've explained what Folding at Home is, basically how it works, what it hopes to achieve, and pre-empted the concern that it might cause performance issues. Now, to be most effective, you should sum up what the benefit is to your school or to the society it is intended to serve. Something that you should always keep in mind whenever you are writing a persuasive letter or giving a presentation is to be sure to go beyond the facts and get to the WIIFY. That is,
What's
In
It
For
You.
