19/11/2008Energy in abundance!

Energy in abundance! The supply of renewable energy will in future be multifaceted. We will obtain our power from the sun and the wind and hydropower and biogas and tidal power plants.

For the only way to ensure that consumers and industry will have a sufficient supply of power in the long run will be to place our bets on as many horses as possible.
There are thousands of genial ideas for producing clean energy. Some are far-fetched, others exist only on paper, but there are also ways of producing energy which are already feasible or are now in use. We provide a few of them below.
Of course a lot of money must be invested in order to introduce a new form of technology on a major scale, especially if the world is preparing for a recession. But some scientists see this as an advantage. One of them is the Belgian Professor of Climatology and Environmental Sciences, Jean-Pascal van Ypersele, Vice Chair of the Intergovernmental Panel on Climate Change (IPCC).

"Since at one time or another we will have to put the economy back on its feet, most probably by means of major investments (in infrastructure), we should now use this opportunity by investing in the climate. So instead of building more highways, we can decide to 
insulate buildings on a large scale, to produce clean energy and to make industry more energy-efficient. There are all sorts of projects that can reduce global warming and at the same time can help improve the economy."

The "sun tree"
The first creative energy idea is by far the strangest: The "sun tree". Entrepreneur Alexander van der Beek invented a real-looking tree from plastic which produces electricity. The tree has leaves which produce electricity in three different ways. On top of the leaves are solar cells, whilst the difference in temperature between the top and bottom of the leaves also produces a bit of electricity.

And finally, microgenerators in the stalks can generate power from the vibration of the leaves when the wind blows. Van der Beek has created a laboratory version of the plastic leaf and swears that it works. However, the question remains, why a tree? Are solar panels so ugly?
"No, I don't find them ugly at all, just like I don't think wind turbines are ugly. But I don't like them in front of my window. Which is the reason why I started to develop the natural-looking 'energy tree' which can convert three types of electricity at once and is therefore extremely efficient while at the same time better looking."
Tidal power generator
The second creative energy solution is extremely simple. There is a construction which looks like a windmill in one of the locks of the IJsselmeer Dam. It resembles a

huge outboard motor and can be lowered into gushing water. 

Pieter de Haas is Operations Director of the tidal energy firm Tocardo, which developed the device.

"It is a tidal turbine, or tidal stream turbine, which can convert streaming water into electricity. In fact, it is nothing more than an underwater wind turbine."
Which also means that you neither hear nor see the turbine - the main disadvantage of windmills. There is always a coming or going tide, which makes tidal energy more dependable than sun or wind energy. And there are tides everywhere, also underwater, so Tocardo's invention can be used anywhere on Earth. The invention has an enormous potential.
Biogas from dessert 
The third clean and clever means of producing electricity is no longer experimental. The Orgaworld company near Lelystad has had a power station fuelled by biogas for years. Biocel - as the plant is called - produces the gas from all kinds of organic waste, from garden refuse to desserts bought in the supermarket. Director Henk Kaskens explains how the enormous biogas reactors operate.
"What we do is remove the oxygen from the reactor. We use the exhaust fumes from the gas turbine to remove the oxygen. We then begin to recycle the seepage, which is the liquid squeezed out of the waste. We heat it up and at the same time heat the reactor. The biogas is then produced spontaneously."
Biogas is nothing more than gas produced by warmed-up rotting organic waste. The electricity produced by the Biocel fermentation plant is supplied directly to the main power net. The electricity costs a few cents more than that produced by traditional power plants, but this is reimbursed by the government. The plant will eventually provide electricity to 3,000 households.

DAP
And finally there is geothermal energy, which of all the means described here is the most promising since it is cost-effective and the technique is reliable and has been tested. Mining engineering students at the Technical University in Delft have founded the Delft Aandwarmte Project (Delft Thermal Warming Project), DAP, to commemorate their faculty's 100th anniversary.

"At a depth of two kilometres in the Delft sandstone is a very large aquifer, a porous layer of stone full of warm water. This was discovered during a drilling by the Nederlandse Aardolie Maatschappij (the largest producer of oil and gas in the Netherlands) in 1995. We want to haul it to the surface by drilling a well and create a continuous cycle by drilling another well two kilometres further and injecting the same water deep underground."
The Delft Thermal Warming Project has already been approved thanks to the involvement of the Ministry of Economic Affairs, the ENECO energy company and the Dutch State Mines, DSM. The deep hot groundwater can heat the campus of the Delft Technical University as well as large sections of the town of Delft. Only one well is needed to supply thirty years of heat. Afterwards, another well can be drilled a short distance away.
Urgent
Of course money will be needed for the initial investments. But we are running out of time. In the speech he gave upon accepting Wageningen University's 'Chair of Climate Change, Environment and Safety' on 16 October, Professor Pier Vellinga said:
"If we want to save the environment, then we will have to quickly change over to renewable sources of energy; we must take this step within thirty years."

Alternative Energies are also Destructive and Evil -- How can Alternative Energies be good when they require materials that originated from places that all environmentalists say are "evil and destructive"? Alternative Energies require "bad" materials for assembly, such as ceramics, carbons, and metals from Mines, and sometimes plastics and other carbon-based materials, which originate from Oil Wells and Coal mines that environmental groups say are all "evil and destructive". Even “natural” plant fiber materials require machinery and processing and transportation, which also require metals, ceramics, and carbon.

From where do we get the SOURCE materials for wind mills, fuel cells, hydrogen and other alternative energies? Most solar electric panels require ceramics and special elements, such as gallium, arsenic, germanium, etc., that came from mines and smelters. Windmills require metals (originally from mines and smelters). Passive and active solar ventilation and tubing for houses usually require metals and sometimes ceramics, which came from mines and smelters.

Environmental groups say that ALL Mining and Oil / Gas Wells are "bad" and "evil", even with full-scale reclamations and restorations. So how can we go to Alternative Energies when these requires materials that are not accepted by the Environmentalists?

Even fuel cells require materials originally from mines and smelters. Fuel cells have to have metals and / or ceramics for the containment, tubing, chemical reactions, etc. The cells, containments and associated materials use materials from mines and oil wells. Think about the engineered things used to even make hydrogen fuel get started for producing energy.

Look at the Periodic Table of all the elements of the earth. Hydrogen (H2) is a usually a gas. When hydrogen is used in a chemical bonding or mixture, it is usually released as a single free ion (H- or H ). Sometimes getters are used to store and transport hydrogen.

It is the cells and containments and associated materials that use materials from mines and oil wells. Go and look at the engineered things used to even make hydrogen get started!

To make Hydrogen "burn" and gain energy from it, there must be the chambers, vessels, tubing, connections and fittings. A characteristic of Hydrogen is that is can embrittle materials over time, especially certain types of metals and steels. Normally stainless steels or other specialty metals are used for most Hydrogen activities. These steels and steels are composed of iron and sometimes chromium and / or nickel to control any corrosion from Hydrogen and also prevent embrittlement as much as possible. The materials for steels ALL come from mines and smelters.

But how is hydrogen (H2 and the H ions) produced from water or other source materials? Either in the reaction apparatus and chambers of the cars or else in processing plants, both of which use metals and ceramics and plastics. If we get H2 from the air, we get it from gas separators which are composed of metals and other "bad" materials.

Environmentalist point to bicycles as environmentally-friendly transportation. To make bicycles, manufacturers must get materials that originated from mining operations (iron, molybdenum, aluminum, ceramics, etc.), oil wells and coal mines for Carbon and plastic materials, and sometime timber for wood. These materials are then processed in plants that also use products from mining and oil wells, and use electricity. How can this be "good" by any environmentalist's definitions?

Look at how many existing Wilderness Areas have abandoned oil / gas wells and also mining sites within their boundaries. Why is that permissible? How is it that reclamations of well drilling sites are either ignored or denied by the environmental groups now? There have been many private groups in the Pacific Northwest (like my grade school in the 1960's) that went out and planted trees, grass, and shrubs in the forests. We even saw some of the lumber companies replanting trees and shrubs. But apparently, none of those good efforts count in the mind of the environmental groups, as seen in recent publications and notifications.

Take a deeper look at what really is going on. Natural resources are needed for everything in our lives, even medical items and alternative energies. But when our natural resources are being closed up and as reclamations are either ignored or badmouthed, we are loosing the materials needed for our daily lives, even for the "nice" Alternative Energies. As a final note, my 1990 car gets the same gas mileage GPM as a modern hybrid car. Go figure.

In a publication from early 1992, the Sierra Club in Santa Fe, New Mexico, USA, openly announced that oil / gas well drillers were still using lead-based (Pb) lubricants. Never mind that the EPA banned their use several years before in the mid-1980s and that the drilling industry had already switched to biodegradable lubricants even before that. Never mind that law enforcement and the EPA later on checked for compliance in the industry. Also, there is new drilling technology, called Coiled Tubing, that allows certain types of well drilling operations from the back of a pickup, thus less impacts than the vehicles you drive. Why don't we don't hear that from the Environmentalists.

Are you familiar with the wilderness near Ruidoso, NM, USA? The wilderness boundaries "captured" some gold and silver / lead mines. The government threatened to sue the mine and claim owners with EPA Superfund status if they did not surrender the land for wilderness designation. Now how is it that places that are supposedly EPA Superfund sites can now be "wilderness" and untouched areas? The 1964 Wilderness Act specified that undeveloped, untouched, and natural areas were to be part of the wilderness areas.
