GCSE Physics | Generating Electricity with Fossil Fuels

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

heat homes or generate electricity in a fuel cell.

Photosynthesis is important because animals eat food, as it is a source of energy.

to basically generate electricity from ..

Growing urbanisation and changes in the pattern of life, give rise to generation of increasing quantities of wastes and it’s now becoming another threat to our already degraded environment. However,

Chemist Paul Alivisatos explains how to generate electricity from ..

Currently they are experimenting with this type of molecular thermoelectric device but, they call it Thermo-Tunneling. This Thermo-Tunneling Power Generation (TTPG)is currently being investigated by Darpa. Several leading nanotechnology experimenters have mentioned that the efficiency can be as high as 70% efficient. Most are reporting near 30% efficiency and that is much greater then the current 5% efficient thermo-electrics available today.

The Plan In my experiment I am going to see how light affects the rate of photosynthesis.

Scientists made it cheaper to produce hydrogen from water

Energy is harvested in many ways using the car and factory waste. Car and factory waste can be used for generating electricity by coating exhaust pipes with a thin material, which is a millionth time of an inch. Physicists also take advantage of the law of quantum physics, which though not used often enough, gives great results when it comes to generating power from the waste.

Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel technology that generates electricity more efficiently and at less cost than traditional photovoltaic systems. These greenhouses are outfitted with transparent roof panels embedded with a bright magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is produced. WSPVs absorb some of the blue and green wavelengths of light but let the rest through, allowing the plants to grow. WSPV technology was developed by coauthors Sue Carter and Glenn Alers, both professors of physics at UC Santa Cruz, who founded Soliculture in 2012 to bring the technology to market.

Grand Challenges - Make Solar Energy Economical

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or

Waste to Energy - Alternative Energy

Coal, like other fossil fuel supplies, takes millions of years to create, but releases its stored energy within only a few moments when burned to generate electricity.

Scientific American : How Does Solar Power Work?

Researchers are trying to duplicate the natural process of photosynthesis. If successful, we can use the “evil” carbon dioxide emitted by power plants and industrial units to good use.
