This is very, very cool! You can read the whole article at http://lifehacker.com/5736907/send-to-kindle-pushes-web-articles-from-chrome-… but here is the part that will interest you:

Kindle users first need to enter their Kindle’s registered email into the extension, then add kindle@klip.me as an approved sender under Amazon’s Kindle management page and add your Kindle’s email address to the extension settings. Once you’re done, clicking the extension’s icon will give you a live preview of how the article will appear on your Kindle and provide you with a “Send” button that will send it to your Kindle. Just make sure Wi-Fi or your Whispernet connection is activated on your device so it has no trouble getting there.

Cool!
