Things are bad, and if we carry on as we are things will be very bad. It is the possibility of preventing bad turning into very bad that motivates many of us to work harder than ever. But pretending that bad can be turned into good with a large dose of positive thinking is, even more so than denying things are bad, a sure-fire way of ending up in a situation that is very bad indeed.

It is such a widely utilized source of energy, probably due to its low cost and indigenous nature, that it accounts for almost 15% of the world's total energy supply and as much as 35% in developing countries, mostly for cooking and heating. ()

This is a very common way of converting organic matter into energy. Burning stuff like wood, waste and other plant matter releases stored chemical energy in the form of heat, which can be used to turn shafts to produce electricity. Let's see this simple illustration of how biomass is used to generate electricity.

Energy from the sun is transferred and stored in plants. When the plants are cut or die, wood chips, straw and other plant matter is delivered to the bunker

This is burned to heat water in a boiler to release heat energy (steam).

The energy/power from the steam is directed to turbines with pipes

The steam turns a number of blades in the turbine and generators, which are made of coils and magnets.

The charged magnetic fields produce electricity, which is sent to homes by cables.

Other ways in which organic matter can be converted into energy include:
Things that can rot, like garbage, human and animal waste, dead animals and the like can be left to rot, releasing a gas called biogas (also known as methane gas or landfill gas). Methane can be captured by a machine called Microturbine and converted into electricity. Sometimes, animal waste (poop) can also be converted into methane by a machine called 'Anaerobic Digester'

Turning Artificial Photosynthesis into an economic reality

The intensity of solar radiation in the Earth’s direction from the Sun is approximately 1.361 kW/m2, a number also called the ‘solar constant’. Accordingly, it is estimated that the power Earth receives is about 96 billion kilowatts from the Sun each second. If this colossal and unlimited energy could be more fully utilized, our dependence on fast dwindling fossil cache will be drastically reduced. Solar energy is available in various forms such as direct solar radiation, wind, wave power, rain (in the form of hydropower), photosynthesis and ocean thermal gradients. Among these, the direct conversion of sunlight into electricity is clean and attractive. This article highlights various routes to directly harness electricity from sunlight.

Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

The ecomodernists look forward to shifting a large fraction of agriculture off land into intensive systems such as high rise greenhouses and acquaculture, massive use of desalination for water supply, processing lower grade ores, dealing with greatly increased amounts of industrial waste (especially mining waste), and constructing urban infrastructures for billions to live in as they propose shifting people from the land to allow more of it to be returned to nature. If renewable energy sources cannot provide these quantities of energy, their proposals would have to involve very large numbers of fourth generation nuclear reactors.

"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes - and his work so far shows - that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

it requires the same basic inputs as photosynthesis.

CE business models fall in two groups: those that turn old goods into recycled materials and those that foster reuse and extend service life through repair, remanufacture, upgrades and retrofits. Both save energy and give people jobs. CE creates wealth by making things last. But since this model reverses conventional practice, selling the concept meets substantial resistance. Only during the last ten years have we seen a sizeable shift toward CE projects. South Korea, China and the U.S. have started research programs to foster CE by boosting remanufacturing and reuse, and there are many more examples. But few researchers have taken note. As new methods are proving effective in industrial applications, they must become part of academic and vocational training. Businesses will need graduates with the economic and technical know-how to change business models. Scientists will need to scan the horizon for CE innovations, and governments and regulators will need to incentivize, promote and coordinate CE innovations.
