Having your own private island is not just about the beautiful views, the privacy and living the good life.

It's also about some of the more practical things, like figuring out the best way to get water and energy on the island.

The private Caribbean island of Sir Richard Branson, Necker Island, which also functions as an exclusive resort, is part of the British Virgin Islands, but it is quite independent when it comes to producing the energy and fresh water that the island uses.

Diesel is shipped to the island to power the three generators that make electricity, but there are no extra-long cables or pipes coming from bigger islands to supply fresh water on Necker.

On our recent visit there, we spoke to Chief Engineer Adam Simmonds, who showed us how he and his team convert the salt water of the beautiful Caribbean Sea to as much as 65,000 gallons of usable water a day for the island.
