Energyville by Chevron: Let’s Play!



Energyville represents an average industrialized city and its consumption of energy.

Goal of the game is to plan energy resources of virtual city in the present with the aim to reach its energy demand as well as to create its sustainable future in 2030. Players can choose between biomass, coal, geothermal, hydro, natural gas, nuclear, petroleum, solar and wind technologies as they try to reach the necessary energy levels.

The challenge is that each of these fuel sources impact three barometers: economy, environment and security. Players can click on any of these barometers to get a clearer idea of what they take into account. For instance, >security< takes into account energy diversity, reliance on imports, unreliable technologies etc.

What amazed me are implications a terrorist attack could have on petroleum supply, or a drought on hydro energy potential of the city!

The game was developed by The Economist Group.

Printing with water instead of ink (video)

Many people are keen to reduce their paper waste, but storing and sharing data electronically is not always feasible. Rewritable paper would be one answer to this problem. Now, Chinese scientists have come up with‘waterjet printing’ that uses paper coated with dyes that change colour when wet and return to their colourless state when dry.

To create rewritable paper the researchers Continue reading “Printing with water instead of ink (video)”

NASA Finds 2013 Sustained Long-Term Climate Warming Trend

NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures.

With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.
