问题
I have a simple informational site that has no ecommerce aspects. It has a comment submission form that I'd like to protect with reCAPTCHA.
Is there any way to use reCAPTCHA without converting the site to HTTPS (at increased cost for certificate and hosting) ?

yes you can they have a javascript api for that also you can verify the response from serverside!
