1. The Pet Plant
   The Green Thumb
2. The Soil Soul

The Pet Plant uses optical sensors in the planter to determine the "mood" of the plant, based on its growing conditions.

1. room temperature
   room noise level
2. soil temperature

Optical sensors in the planter measure the soil temperature and moisture and light levels, and then the device displays a digital facial expression based on the plant's status. A happy face means a happy plant!

1. Sweden
   Denmark
2. Spain

To maintain the integrity of its historic buildings, Sweden restrict landowners from building balconies onto homes. That restriction led to the development of a fold-out balcony.

1. steel and aluminum
   100 percent recycled plastic
2. bamboo

The fold-out balcony is fitted to the size of an existing window opening, and a frame is made from steel and aluminum. The balcony has reinforced steel bars to allow for better control while using the motorized fold-out system.

1. incandescent light bulbs
   LEDs
2. neon lights

The interactive coffee table, called the Wave, uses LEDs (light emitting diodes). Optical sensors read pressure changes on the table surface and cause the lights to change via circuits through the table.

1. It is made of 100 percent recycled material.
   It uses just 35 watts of energy when fully alight.
2. It is made of organically grown bamboo.

When fully alight, the coffee table uses only 35 watts of energy, though it's likely to be inactive a lot of the time, depending on how you use your coffee table. In addition, the Wave is made from American maple wood and non-formaldehyde plywood and is varnished with a water-based lacquer.

2. $20,000

About $15,000 will get you a Vertebrae bathroom, which could be economical given the cost of replacing each separate bathroom fixture.
