company: The Hydroponicum is moving into the area of renewable energy and green technologies. At this time there is no facility in Scotland to demonstrate these technologies and so it will be the first “Eco-centre” in the country. The company has incorporated renewable energy exhibits into the visitor centre and now has products related to this area.

product: small and stylish, its water-powered desk products are innovative and unique; they run entirely on water and need only be topped up once a month on average. There is no need to buy any batteries or plug in any cords to use the LCD clock or calculator. It is sufficient to pull out the two tiny reservoir tubes from underneath the clock's sleek arch and to fill them. The power produced will be enough for two months of operation. The set includes a desktop clock (dimensions: 7 x 8 x 3 cm), an alarm clock (dimensions: 12 x 14 x 3 cm), and a calculator (dimensions: 12 x 8.5 x 1.5 cm).

sustainability features: perfect for the pollution conscious business-type, these products are environmentally friendly. They work using nothing more than ordinary water. The secret is a patented revolution in fuel cell technology that harnesses the energy of water molecules to provide a futuristic stream of pollution-free electrical current.
