Arrrrrr! Change your default language in google to "pirate" and the sidebar will sink to the bottom of the internets! This will not effect search results at all.
Save energy and get rid of the everything bar by using http://www.blackle.com/ - It's as dark as the mood of many google users these days.
Use google mobile! Just enter "www.google.com/m" You can also use your own country like "www.google.co.uk/m"
Using the experimental google keyboard shortcuts disables the sidebar because it would interfere with the cursor.
Turn it on here: http://www.google.com/
You might want to consider using Scroogle. It's a search engine powered by Google.
