Traditional electrical wires have had a good run since their development. But what if you could just slap some paint on a surface to create the circuit you’re after? Thanks to one London-based company, Bare Conductive, you can.
Titanium dioxide nanoparticles coated with cadmium sulfide produced a yellow paste that, when painted onto a transparent conductive material, generates electricity.
The next coat of paint you put on the outside of your home could generate electricity from light — electricity that can be used to power the appliances and equipment on the inside.
The mediterranean cuisine is known to be one of the healthiest, and yet, Spaniards like their fried tapas or churros every now and then. In 2010 the recycling centers, called ‘Green Points’, collected 195.136 liters of used kitchen oil from households, which only counts for 2,5% of the total oil used in one year by Barcelonians. In order to make recycling oil easier, Barcelona City Council has launched the Olipot, an easy to use bottle that helps you bring your old oil to the recycling centers. That way it does not contaminate the water but instead can be turned into soap, biodiesel and paint.
