Lots of steam

World's Largest Solar Cooking System Installed in India

If poorer countries are going to reduce their CO2, while still cooking food, then systems like this will presumably have a role to play:

India already had the previous world's largest solar-powered cooking system, serving 15,000 pilgrims daily at the Tirumala temple in Andhra Pradesh. But now that one has been been one-upped, Taragana reports. The new system has been installed at the shrine of 19th century saint Sai Baba in Shridi and can feed up to 20,000 people per day:

The system generates some 3,500 kg of steam daily, which replaces on a yearly basis 100,000 kg of cooking gas.

3,500 kg of steam? That's how you measure steam?

Anyhow, it would be interesting to know whether the cost is worthwhile in terms of gas savings.
