Solar dryers are special structures that enhance the drying power of the sun and protect the agricultural product from dust, dirt, and insects. Table below shows a block diagram of an active solar drying system, consisting of solar air collectors, a drying unit or chamber, and an air handling unit. An active solar drying system can accommodate the use of a backup heat source when there in not enough solar heat available. (more…)

Corporate environmental strategy (CES) involves the tools, management programs, processes, and product development choices that allow a firm to pursue competitive advantage through environmental management strategies.
Management scholars such as Deming and Juran spent several decades after World War II making sure that quantity and quality processes entered the plans of corporate strategy, along with the classical concerns of price, technical quality, and distribution matters. In a similar but often more diffuse manner, the proponents of corporate environmental strategy began, in the l970s through the l990s, to alter the standard decision models of corporate strategy to include externalities that challenged the future growth of corporations, such as new environmental regulations or irregularities in energy markets and pricing.

Sir Arthur Eddington’s general address on subatomic energy at the 1930 World Power Conference in Berlin stirred the imagination of every scientist and engineer present. The challenge was clear: find a practical means of accessing, controlling, and using the enormous energy locked in the atom as predicted by Einstein’s remarkable mass–energy relation, E=mc2. On December 2, 1942, Enrico Fermi transformed Eddington’s visionary challenge into reality by producing the world’s first controlled, self-sustaining nuclear reactor, Chicago Pile 1. Six decades later, nuclear energy now produces 16% of the world’s electrical power. (more…)

Nuclear energy has some distinct advantages in strengthening the external dimension of energy supply security. These include:
• Nuclear power plants produce electricity domestically. Their capital and labor inputs are also provided domestically. With more than 90% of its inputs in terms of value sourced domestically, it can be considered a largely domestic source of energy and electricity.
• Of course, a majority of OECD countries import part or all of their requirements of uranium plutonium. (more…)

Active solar hot water systems water are usable with air, liquid, vapor or liquid collector fluid or gas to liquid process. Hot water production with an air-heating collector’s distribution for heating is usually performed in the large space heating panel systems. The losses in the process of heat transfer are high. Air systems work not as well as units of the liquid to heat the water. Air systems are generally only capable of hot water 70 to 95F. (more…)
