Why negative earth and not positive earth on a vehicle?
The electrical term "earth" or "ground" is a connection that runs through the entire electrical system. It may or may not be connected literally to the soil. When a system is "negative earth", it means the electrical earth has a negative polarity. Power can then be run back and forth using only one wire carrying the positive polarity. Similarly, electrical signals need only one wire. At the destination, the circuit is completed by connecting the "negative" terminal to earth or ground.
Until the 70s, cars were built with either a positive or negative earth, with popular British vehicles being among the last to be built with positive earth. Negative earth was adopted globally by automobile manufacturers for the sake of standardization. It was the introduction of radios in automobiles that may have seen negative earth automobiles being favoured. It was also thought positive earth vehicles rusted quicker.
The US telephone system also uses a positive ground, after starting out with negative ground. However, the trolley cars in Atlanta, Georgia were causing electrical induction interference, which led to the phone cables literally falling apart. Every kind of solution was tried, but they all failed, until as a last resort the phone company flipped the polarity, and it has stayed this way till the present day.
What is the best free Google Earth to download?

How can you give updated information to Google Earth?
Google providers a data error reporting form (via website) to submit corrections to google's imagery, street names, directions, and so forth.

No, Google Earth Pro is the paid professional version that costs $399 per year.
It does have a free 7-day trial period to use and evaluate after which you need to convert trial license into full license.
Note that Pro and free version both use the same high-resolution imagery.
*UPDATE* as of Jan 30, 2015 Google made Google Earth Pro available for free. Login with your email address and the license key GEPFREE and that's it.

Google Maps uses the Mercator projection also with the WGS84 dataum.
The vertical component (altitude) is measured from the vertical datum, which is the Earth Gravitational Model 1996 (EGM96) Geoid. Altitudes are measured in meters.

You can view the Flightwise web site for these Google Earth layers or use the direct link in the related link section below.
How do you search location using coordinates in Google Earth?
Google Earth has a search/fly-to option allowing you to type in a specific address, partial address, or just a city name, zip code, airport code, or country to search.
You can also enter an explicit latitude, longitude coordinate (e.g. 37.78, -122.4) with latitude first. If location is not where you expect (happens sometimes) then prefix the coordinate with "loc:" (e.g. loc: 37.78, -122.4) and enter this into Google Earth's Search/Fly-to input field.
If the search option is not showing then you might have to enable the Sidebar panel in the View menu.

Why is there no ice on Google earth the north pole?
Both poles the south and the north melt during summer periods. The north pole melts at a higher rate than the south. In recent years the north pole has become increasingly thinner. In 2008 it was just 3 metres, in 2009 it is down to 1 metre. Scientists predict by the end off the 2009 summer period there will be very little ice at all. Google earth is just showing this natural seasonal pattern.
Is there a website where you type an address and you see a house from space?
Google has a site with satelite photos of just about everywhere. Not always clear or recent. My parents' home (Arkansas) is shown with cloud cover, unable to see much detail. Our home (Wisconsin) is clear enough to see that the sod hasn't been laid yet, which means the photos is about 5 years old.

For example, if you're in London then you can jump to 1945 to see WWII imagery.
3-D Building layer
Note that the 3-D building layer are current buildings and not associated with any particular time period so you may want to turn off this layer otherwise it may not match well with the older imagery.
Newer Imagery
Sometimes there are actually newer imagery available in Historical Imagery due to Google's quality control process such as the newer image having more clouds or other defects making the older image "better".
Street View
