Applications of The sieve of Eratosthenes 
The sieve process produces the stream of all prime numbers 
 The first 25 prime numbers made by sieving a sufficiently long prefix of the integers starting from 2. 
In addition, however, you must load the Scheme stream stuff.
The most remarkable function is filterstreams, which illustrates that
it is necessary to rewrite all our classical higher order function to
stream variants. This is clearly a drawback!
