I have a Master's in Innovation Management so I'll bite :) One of my professors has said, "The difference between an idea and innovation is the first sale." Ideas are great and where things start, but yes completely worthless unless you act on them and turn them into viable products or services.
Try talking to entrepreneurs who are working on building their own companies and see how they do it. See if there is anyone out there who you'd potentially be interested in partnering with. Know what your end goal/outcome should be (aka have an exit strategy). Study the innovation process - how something goes from an idea to full scale production.
Incremental innovations are also innovations... improvements on existing products. They may not get as much attention as the disruptive innovations, but they are still important nonetheless.
