Biofuels Coal and crude oil are non-renewable resources. They take so long to form that they cannot be replaced once they have all been used up. This means that these fossil fuels are likely to become more expensive as they begin to run out. Petrol‚ diesel and other fuels produced from crude oil make a range of harmful substances when they are burned‚ including: carbon dioxide carbon monoxide water vapour particulates (solid particles) sulfur dioxide oxides of nitrogen or NOx.

needs new ideas and innovation. These ideas/ concepts and innovations needs to be fine tuned to stay ahead of competion. ERP system is one of the innovations done and implemented successfully worldwide. There are various modules of these ERP systems. I am considering one of the modules as vendor PO and PO status tracker. I will be considering Purchase order Tracking system (here onwards to be called as PO Tracker) for discussion. PO Tracker is designed to track the PO raised with vendors. I am

Background * Three solar energy * Solar electric (太阳电能): convert the sun’s energy into electricity * Solar thermal (太阳热能): used the sun for heating or cooling * Concentrating solar: mixed both above as it used small optical mirrors to collect solar energy and convert the sunlight to heat. The heat was then applied to a liquid and gas to turn a turbine‚ thereby creating electricity * Grid-tied * Solar electric system that were connected to an electricity utility

Space-based solar power (SBSP) is the concept of collecting solar power in space for use on Earth. It has been in research since the early 1970s. SSPS consists of a space-based power generation/transmission facility that gathers sunlight‚ converts it into microwaves or laser beams‚ and transmits those to the ground; and a power receiving facility on the ground. Space-based solar power essentially consists of three elements: • a means of collecting solar power in space‚ for example via solar cells

power point tracking (MPPT) algorithms in a photovoltaic simulation system. The Matlab/Simulink is used in this paper to establish a model of photovoltaic system with MPPT function. This system is developed by combining the models of established solar module and DC-DC buck-boost converter with the algorithms of perturbation and observation (P&O)‚ incremental conductance (INC) and hill climbing (HC)‚ respectively. The system is simulated under different climate conditions and MPPT algorithms. According

Midland Resources 1. How are Mortensen’s estimates of Midland’s costs of capital used? How‚ if at all‚ should these anticipated uses affect the calculations? The cost of capital is the minimum acceptable rate of return for new investments in the corporation. Estimates of Midland’s cost of capital are used in many analysis within Midland‚ including asset appraisal for both capital budgeting and financial accounting‚ performance assessments‚ M&A proposals‚ and stock repurchase decisions.
