I Heard about Terry and listen to some Podcasts he was on, sound like he does have a lot of experience and have a good business module that works well for him.

Mid and longer term I also consider what cartoon characters with modulated voices say: For example, a silver spot price of $20.00 per ounce and a physical silver price (I can hold it in my hand) of $80.00 per ounce. http://www.youtube.com/watch?

Batteries for those pesky smoke alarms is a must

With Ca policy driving toward AB 32 objectives, Title 24 updates, solar continuing to boom, electric vehicles hitting mainstream, Tesla battery units, water concerns... seems like there are a lot of interesting elements to consider with new development.

I will need an electrician who can hook up solar and a battery pack, and a plumber who can hook up a rainwater capture system. 

Besides recharging a rechargeable battery (fast charge, no waiting), there are hydrogen fuel cells (refill the hydrogen tank with hydrogen) vying for consideration.

As to cell phones, keep the batteries charged!
