5 Technological advances in Energy

Super bright flashlights are a reality even with rechargeable batteries which should be used in all gadgets to reduce the impact of regular lead batteries on the environment. It is time to adopt more energy efficient sources of fuel to save the planet.

Here are five advances that everyone must know about.

  1. Artificial photosynthesis

Clean liquid fuel is the need of the hour and scientists have developed a bionic leaf which with the help of catalysts from a cobalt-phosphorus alloy will be able to produce liquid fuel through artificial photosynthesis which incidentally is 10 times more efficient than that of an average plant.

  1. Solar thermophotovoltaics

The usual solar panels can currently absorb energy only from the visible light of the sunlight’s spectrum which is very limited. To overcome this drawback scientists are using nanotechnology to channelize the energy from the entire color spectrum which includes the invisible infrared and ultraviolet rays. The light is converted into heat energy and passed on only to be reconverted as light bands that photovoltaic cells in the solar panels can convert.

  1. Perovskite solar cells

Cells that absorb solar energy usually degrade fast. Currently, perovskite solar cells are used to capture the sun’s light and convert to energy because they are easy to manufacture and are more effective than standard photovoltaics. Since their durability is a challenge, scientists are finding ways to overcome that. Once that happens the possibilities are plenty in the field.

  1. Carbon storage

Power generators are some of the biggest emitters of carbon dioxide and a major contributor to the carbon footprint. The latest technology has learned to capture carbon emission at the source and is experimenting burying it under the ocean and turning it to stone. While this is great for the atmosphere the implications are to be explored.

  1. Carbon dioxide to ethanol

By recycling the captured carbon dioxide into usable fuel we will kill two birds with one stone- solve fuel problem and that of global warming.
