The next best thing for solar cells: carbon nanotubes

Carbon in its wide range of shapes and variations seems to be the new material to work with no matter what sector you’re in. Especially the possibilities of carbon in its numerous nano forms seem limitless. While yesterday it was … Continue reading →

Improved solar cells and electronics thanks to copper nanowires

As much as we would like it, solar energy still isn’t competitive with fossil fuels, mostly because one of the main materials used in their production is the incredibly expensive metal indium. But that might change in the near future … Continue reading →

Biomaterials should be more important than biofuels

When talking about a biobased economy, most people think biofuel. And who can blame them, since gasoline alone is good for about half of global petroleum use? A transition from petroleum to biomass as a source for fuel would put … Continue reading →

Cheap, limitless hydrogen from wastewater

An inexhaustible source of hydrogen without the need for electricity and completely carbon neutral. It sounds too good to be true, but in this case it appears it is not, as Penn State engineers have developed a method to do … Continue reading →

Today’s paradox: coal is not worse for climate than natural gas

It´s basic chemistry: coal is mainly carbon, if you burn it you get lots of CO2. Natural gas is mostly methane, and that’s a different story. With methane just ’20 percent of the burned atoms’ are carbon, the rest is … Continue reading →

Tequila plant agave seems excellent source of biofuel

The food versus fuel debate has put large-scale biofuel production in a squeeze in recent years, but competition with food crops is just one drawback for which biofuel crop production is criticised. So far each biofuel crop has shown to … Continue reading →

Making batteries greener and better with algae

Existing batteries are not known for their environmentally friendly components, since most contain heavily toxic chemicals. The much used lithium-ion batteries, best known for their use in cell phones and electric cars, for instance can contain pollutants that may decrease … Continue reading →

Solar power industry responsible for large lead emissions

The fact that the use of fossil fuels can be harmful for the environment is well known. Previous research even showed that coal-fired power plants are responsible for heavy metal emissions like mercury and we all know that the lead … Continue reading →

Hydrogen fuel produced from sunlight and safely stored

Hydrogen has long been commended as a clean and efficient alternative to gasoline, but so far it hasn’t really been able to live up to expectations. Mostly because it has to be derived from non-renewable sources like coal and natural … Continue reading →
