I publish a popular website for the field of nanotechnology. I've been the number 1 site for this field for the last 3-4 years and I'm still not making enough income from it to support myself financially.

I would love to have some ideas for how to make more money from the site. My current income producing methods are: google adwords, banner ads, 2 paid newsletters, a few affiliate products and some consulting work.

The site is www.nanotech-now.com

Thank you for your help!

Brian
