Artificial Leaf Closer to Reality. Humans Today Consume 15 trill watts of power, 85% from fossil fuels.

such as oil, coal, and natural gas. That massive fossil fuel consumption produces some nasty side effects, including climate change, acidified oceans, and oil spills.

These problems are likely to grow far worse in coming years, as worldwide energy use is expected to at least double by 2050.

Renewable power sources, such as solar photovoltaics and wind turbines, aim to fill this demand, and they are making steady progress at providing electricity at ever cheaper costs. But electricity has a key drawback as an energy carrier. It’s difficult to store in large quantities, which means it can’t be used for most heavy industry and transportation applications, such as flying planes or driving heavy trucks. So researchers have long sought to use the energy in sunlight to generate energy-rich chemical fuels, such as hydrogen gas, methane, and gasoline, that can be burned anytime anywhere

!! Every 40 minutes, enough solar energy hits the USA to cover its energy needs for 1 year !!

!! Windpower Could Provide 40 Times Earth's Power Needs !!

If that area on picture, size of Austria, was covered in solar thermal power plants, it would produce enough electricity to meet WORLD demand ... hard to believe, but that's what exactly it is.

Smaller red square area covered with soalr power plants would satisfy electricity needs of Europe, the smallest one would cover Germany's energy demand...

First practical 'artificial leaf', milestones in the drive for sustainable energy. The future of energy generation.


Advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.

Nature is powered by photosynthesis, and I think that the future world will be powered by photosynthesis as well in the form of this artificial leaf

A practical artificial leaf has been one of the Holy Grails of science for decades

The artificial leaf shows particular promise as an inexpensive source of electricity for homes. Our goal is to make each home its own power station,

Device is fashioned from silicon, electronics and catalysts, substances that accelerate chemical reactions that otherwise would not occur, or would run slowly.

Placed in a single gallon of water in a bright sunlight, the device could produce enough electricity to supply a house with electricity for a day,

It does so by splitting waterinto its two components, hydrogen and oxygen.
