Several other types of capacitor are available for specialist applications. Supercapacitors store large amounts of energy. Supercapacitors made from carbon aerogel, carbon nanotubes, or highly porous electrode materials, offer extremely high capacitance (up to 5 kF as of 2010[update]) and can be used in some applications instead of rechargeable batteries. Alternating current capacitors are specifically designed to work on line (mains) voltage AC power circuits. They are commonly used in electric motor circuits and are often designed to handle large currents, so they tend to be physically large. They are usually ruggedly packaged, often in metal cases that can be easily grounded/earthed. They also are designed with direct current breakdown voltages of at least five times the maximum AC voltage.

How many times the maximum AC voltage are AC capacitors designed to withstand?
Answer: at least five times the maximum AC voltage

The centre of Southampton is located above a large hot water aquifer that provides geothermal power to some of the city's buildings. This energy is processed at a plant in the West Quay region in Southampton city centre, the only geothermal power station in the UK. The plant provides private electricity for the Port of Southampton and hot water to the Southampton District Energy Scheme used by many buildings including the WestQuay shopping centre. In a 2006 survey of carbon emissions in major UK cities conducted by British Gas, Southampton was ranked as being one of the lowest carbon emitting cities in the United Kingdom.

What utility company sponsored a carbon emissions survey in 2006?
Answer: British Gas

The distinctive characteristic of Italian Gothic is the use of polychrome decoration, both externally as marble veneer on the brick façade and also internally where the arches are often made of alternating black and white segments, and where the columns may be painted red, the walls decorated with frescoes and the apse with mosaic. The plan is usually regular and symmetrical, Italian cathedrals have few and widely spaced columns. The proportions are generally mathematically equilibrated, based on the square and the concept of "armonìa", and except in Venice where they loved flamboyant arches, the arches are almost always equilateral. Colours and moldings define the architectural units rather than blending them. Italian cathedral façades are often polychrome and may include mosaics in the lunettes over the doors. The façades have projecting open porches and occular or wheel windows rather than roses, and do not usually have a tower. The crossing is usually surmounted by a dome. There is often a free-standing tower and baptistry. The eastern end usually has an apse of comparatively low projection. The windows are not as large as in northern Europe and, although stained glass windows are often found, the favourite narrative medium for the interior is the fresco.

Instead of rose windows, what type of windows do Italian cathedral facades usually feature?
Answer:
occular or wheel windows
