Light down a wire for solar power

Light down a wire for solar power

Solar power could be produced cheaply in specially designed optical fibres, say researchers.

The work, published in the journal Angewandte Chemie, makes use of nanometre-scale wires built around optical fibres like bristles.

Those wires give the light much more surface area to interact with, leading to higher overall efficiencies.

However, only the ends of the fibres must be exposed – they funnel the light elsewhere for power generation.

Instead of roof-sized panels, small collectors could be used on the roof, with the real machinery of solar power generation tucked away, for example, between a home’s walls.

“Using this technology, we can make photovoltaic generators that are foldable, concealed and mobile,” said Zhong Lin Wang of the Georgia Institute of Technology in the US.

Dye job

The most efficient – and the most familiar – solar cells are those based on silicon, which absorbs light, generates electrons, and shuttles them around to create a current.

Recent years have seen leaps and bounds in the use of so-called dye-sensitised solar cells, in which the electrons are released from special dye molecules designed to absorb sunlight.

While dye-sensitised cells are promising because they make use of cheap and robust materials, they are comparatively inefficient.

The new method starts with commercial optical fibre, like that used in telecommunications, with the outer layer stripped off.

The team then creates a “forest” of zinc oxide nanowires around the fibre, and deposits the dye molecules over them. This creates a much larger effective surface area that helps to boost the cells’ efficiency.

What is more, the light needs enter only at the ends of the fibres, so a large-scale implementation could see just small collectors on a roof, with the bulk of the power-generating materials tucked away.

“Optical fibre could conduct sunlight into a building’s walls where the nanostructures would convert it to electricity. This is truly a three-dimensional solar cell,” Professor Wang said.

Professor Wang said that future modifications to the surfaces of the nanowires could boost the devices’ efficiency.

“It’s really nice, elegant work,” said Saif Haque, a solar cell researcher from Imperial College London.

“It’s a clever way to make better use of the light.”

Hydrogen – Wind Power – Generator

Hydrogen is the ultimate fuel because when burned it produces only heat and no carbon dioxide. The Windhunter system is a better and cleaner way to get hydrogen than the current method from natural gas.

Hydrogen can be produced by wind turbines and electrolysers on the proposed WINDHUNTER vessels. These large ships or platforms will operate out of sight of land either moored or anchored while facing into the wind and the oncoming waves. Millions of them can operate on the world’s oceans with minimal environmental impact and human resistance.

Converting to a hydrogen energy system world wide will save earth’s resources, reduce heat trapping gases and bring peace since wars over land based resources will become unnecessary. The wind energy will be available for harvesting as long as the sun shines on our beautiful rotating earth.

Biologically Inspired Ocean Power Systems

biowave_home

BioPower Systems is commercialising ocean power conversion technologies. Through application of biomimicry, we have adopted nature’s mechanisms for survival and energy conversion in the marine environment and have applied these in the development of our proprietary wave and tidal power systems.

Our technologies inherit benefits developed during 3.8 Billion years of evolutionary optimization in nature’s ocean laboratory.The resulting systems move and sway in tune with the forces of the ocean, and naturally streamline when extreme conditions prevail. This leads to lightweight designs and associated low costs.

The inherently simple bioWAVE™ and bioSTREAM™ devices are designed to supply utility-scale grid-connected renewable energy using efficient modular systems. These systems will reside beneath the ocean surface, out of view, and in harmony with the living creatures that inspired their design.

It took me awhile to finally get this done but it’s decent for the message I’d like to throw out to people. Feel free to share this with social lists and people who you think would like to learn more about alternative education :)

I also wanted to post this section of an interview with David Icke that pretty much explains my position on “New Age” information. Take a look.
