With all the talk about The Apocalypse and "where will you be?" business, I finally gave in and tucked one of these radios in my emergency survival bag, under my bed. Seriously, I do advise one should always be prepared for emergencies. This Eton hand-crank radio also works as a generator - it comes with a built-in cell phone charger, flashlight, and emergency siren. However, for general use, it can also be powered by batteries or AC adapter (included). $50

An entire self-sustaining ecosystem thrives within this attractive hand-blown glass sphere: Plants, live shrimp, algae, and microorganisms. It requires only indirect light and moderate temperatures, and offers hours of fascinating viewing. The Ecosphere is available at Viva Terra for $89.

A plug-and-go electric motor bike that can go 20-25 miles at top speed (24 MPH) and requires around three hours to charge. The big plus... It costs only half a cent per mile to operate. Available for $1,199 at ShiftYourGift (A site offering sustainable gifts and will donate 5% of your purchase to a nonprofit of your choice).

The clock requires no batteries. Simply add water to the back reservoir and the clock will run for a few weeks. Adding flowers will take away water and shorten the life cycle , but it'll look very nifty. $13 at ThinkGeek.

One minute of shake will get you 100 minutes of light. This Shake Flashlight requires no batteries or hand-crank. You literally shake it to activate electromagnetic energy, which is what charges this device. It is waterproof and floats, so if you accidentally jumping into the pool with the flashlight on you, it will not be a problem. For the flashlight. $17
