Biomass Energy

http://ecoskimple.org/de/?q=Rolf-Albern-Biomass-Energy - Biomass is biological material derived from living, or recently living organisms, like alcohol fuels, waste, and wood. It is a renewable energy source because the energy it contains comes from the sun. Biomass is the oldest source of renewable energy known to humans and supplies almost 15 times as much energy in the United States as wind and solar power combined. Biomass energy has been used since people began burning wood to cook food and keep warm.

Europe's most important medical trade fairs

The world's largest medical trade fair is the MEDICA in Dusseldorf, where each year about six hundred speakers introduce the latest medical knowledge of their discipline and some three hundred suppliers present their latest discoveries and developments. Outpatient as well as inpatient technological tools up to new digital processes of health care are presented in Dusseldorf. So, all in all the entire modern achievements of world medicine are showcased there.

For manufacturers of medical products the MEDEC Europe is the most important one of all trade fairs on the European continent. It provides its visitors comprehensive information on the current range of products and services in the field of development and manufacturing of medical devices. At the MEDTEC Europe manufacturers are given the possibility to order the latest medical equipment as well as individual components.

Due to the fact that at the MEDTEC Europe, world's leading suppliers of medical materials and technologies meet up, the offer includes the following areas:

- Assembly and manufacturing technology

- Materials for all application areas

- Packing, sterilization and clean room systems

- Synthetic / disposable products and diagnostics

- Outsourcing / contract manufacturing

- Motors, pumps, and motion control

- IVD manufacturer

- Technology for quality assurance and control

- Accurate and high-performance cutting / subtle cutting

- Medical Electronics

In the field of biotechnology, the BIO-Europe is of greatest importance. At this annual trade fair the best known names of the industry as well as senior decision makers meet in the context of workshops and forums in order to deal with future key themes. In addition, at the BIO-Europe, the latest products and technologies are showcased.

Wind Power

China may have been the birthplace of the windmill. The earliest actual documentation of a Chinese windmill was in 1219 A.D. by the Chinese statesman Yehlu Chhu-Tshai. It is assumed to have been used primarily for grain grinding and water pumping.

A vertical axis system called panemone device was developed in Persia about 500-900 A.D. It was apparently used for water pumping. The first document design features vertical sails made of bundles of reeds or wood which were attached to the central vertical shaft by horizontal struts.

Grain grinding windmills consisted of a grinding stone affixed to a vertical shaft driven by a horizontally mounted wind rotor. The mill machinery was commonly enclosed in a building. Wooden cog-and-ring gears were utilized for the vertical axis rotor to drive the horizontal axis grindstone.

Rotor designs have their roots in sailboat design from which early knowledge of wind forces was learned by experimentation. On the island of Crete sail-rotor windmills are still used to pump water. Steel bladed versions of these pumps were used through out the American heartland in the late 1800's. By 1970 over six million small windmills were installed in the U.S. primarily for pumping water. Raised water towers were a common storage method that provided on demand water pressure delivery. By the mid-1920's Parris-Dunn and Jacobs were major suppliers for wind-electric to the mid-west and Great Plains area. The early success of the Midwest wind turbines actually set the stage for the possibility of more extensive wind energy development in the future.

The development of bulk-power, utility-scale wind energy conversion systems was first undertaken in Russia in 1931 and operated for two years on the Caspian Sea. Experimental wind plants were tried in US and Europe from 1935 until 1970 but failed to be practical.

Solar Energy

Solar thermal energy is a technology for harnessing solar energy for thermal energy and it is different from photovoltaics, which convert solar energy directly into electricity. There are many applications of solar thermal energy such as drying, heating and water distillation.

Many solar thermal technologies have existed for centuries and have established manufacturing bases in many sun-rich countries. Manufacturing can be done on a small scale without using expensive equipment. In 2008 solar thermal energy industry in Europe has grown over 60%.

Solar distillation is necessary in areas that clean water is not common. Its main aim is to provide people with purified water. Basic solar stills can be used to remove fluoride and salts to produce drinking water. http://energysourcefacts.org/solar_energy_solar_thermal_energy.html

Biodegradability versus Photodegradability - Rolf Albern from EcoSkimple

Biodegradable means being able to be broken down into more basic components by fungi, bacteria or other simple organisms. Most chemicals are biodegradable but it takes different amount of time to break down, for example a piece of bread will break down rather quickly, and a piece of plastic will take decades and beyond.

Photodegradable objects are substances that can be broken down into their simpler forms by the action of ultraviolet rays present in the sunlight. Plastic, for example, is photodegradable. http://ecoskimple.org/
