A Waitrose supermarket has turned to an unusual source for its electricity supply - tomatoes sold in store. Tomato plants, grown in greenhouse are fed carbon dioxide, which, combined with the natural preocess of photosynthesis, generates heat to turn a turbine, which generates electricity.

Tomatoes are my favourite food or should I say fruit? Some say tomatoes are easy to grow, I find growing tomatoes organically is not as easy as they say. The very first crop of tomatoes grown in uncontaminated soil is easy as there is less chances of the plants picking up tomato diseases, such as wilt.

Two years after the release of the first GM plant, the FLAVR - SAVR tomato in the USA in 1995, there was still not a single publication in peer-reviewed journals probing into the safety of GM foods.

The tomato (Solanum lycopersicum) is a plant in the Solanaceae or nightshade family, as are its close cousins tobacco, chili peppers, potato, and eggplant. The tomato is native to Central, South, and southern North America from Mexico to Peru. It is a perennial, often grown outdoors in temperate climates as an annual, typically reaching to 1–3 m (3 to 10 ft) in height, with a weak, woody stem that often vines over other plants.The leaves are 10–25 cm long, pinnate, with 5–9 leaflets, each leaflet up to 8 cm long, with a serrated margin; both the stem and leaves are densely glandular-hairy. The flowers are 1–2 cm across, yellow, with five pointed lobes on the corolla; they are borne in a cyme of 3–12 together. The word tomato derives from a word in the Nahuatl language, tomatl. The specific name, lycopersicum, means "wolf-peach" (compare the related species S. lycocarpum, whose scientific name means "wolf-fruit", common name "wolf-apple").
