potentially provides the answer to global energy needs. In ten hours the Sun provides the Earth more energy than is contained in all . Even though the amount of theoretically available far exceeds most, if not all, other energy sources (renewable or not), there remain practical challenges to utilizing this energy.

In general, solar energy remains subject to a number of limitations that have kept it from fulfilling the promise it holds. Harnessing this energy in a cost-efficient manner is one of the major impediments to the more wide-spread use of this energy source.

A low cost upgrade solution to increase the solar energy production is to attach mirrored reflectors to the solar PV panels – see the picture. To avoid PV panels overheating in hot days the movable reflectors are used.

Today, across the world there are open-air car parking spaces that are exposed to the elements. In many such car parks attempts are made to provide shade for the individual cars through fixed car port roofs.

The present address an important aspect of efficiently harnessing solar power by providing a system that increase harnessing of solar energy by providing additional sun light onto solar PV ’ surface.

Such systems may incorporate shaded parking roofs, photovoltaic generation of clean power, and use of the solar energy so generated to recharge plug-in hybrid and electric vehicles parked there under, as well as mechanisms for returning generated power back to the electric utility’s so-called power smart grid and/or for other more immediate use or storage.

How to augment solar PV generation by flat mirrored reflectors ?

May 13th, 2012 DriveTek

New patented down road (highway) Power Plant with Fixed Reflector Augmented PV Modules and turbines for battery charging of and plug-in hybrid vehicles – see video.

The 2011 Chevy Volt, primarily an electric (or hybrid) vehicle is advertised as requiring 10 to 12 hours of charging at 110 volts. If the charging current is between 15-30 amperes of current @ 110 volts, the power is on the order of 1650 to 3300 watts per hour. If the charge is 10-12 hours, one can multiply by the number of hours to produce the hours. While charging is available to some people in their homes/garages, it presents a problem to apartment dwellers and to people who do not have access to a charging system. Accordingly, making charging systems available through parking meters or charging stations is highly desirable.

Remote power stations may be useful to supplement or as an alternative to the home recharging concept. Solar power does not require the installation of power lines for supply of power to remote charging stations.

Background solar powered devices includeU.S.patent application Ser. No. 12/025,737 entitled “SOLAR-POWERED LIGHT POLE AND LED LIGHT FIXTURE,” hereby incorporated by reference, which discloses a solar-powered system that includes a flexible, wrap-around, preferably self-stick panel of photovoltaic laminate applied to the outside surface of a light pole. An LED light fixture is connected preferably at or near the top of the pole and has the same or similar diameter as the pole. The LED light fixture has multiple columns and rows of LEDs and an interior space for air flow to cool the LEDs. The pole preferably also has vents and passage(s) for creating a natural updraft through at least a portion of the pole and the light fixture, for cooling of the photovoltaic panel interior surface, the LEDs, and/or other equipment inside the fixture or pole, and batteries that may be provided inside the pole or pole base.

U.S. Patent Application No. 2006/0149607, hereby incorporated by reference, discloses means for programming and controlling an LED assembly using a programmable and feedback means.

Once the leaves the owner’s charging facility, the range of travel is limited by the amount of charge in the batteries of the vehicle. There is a need for an auxiliary power source to enable recharging of electric vehicles at remote locations.

Embodiments of the present invention include assemblies for use both with home charging systems and remote charging systems. The assemblies may be powered by conventional power lines or may be solar powered.

Understanding free solar energy

May 13th, 2012 DriveTek

Photovoltaic (PV) cells comprising single crystal and/or thin film sub-modules are widely used to convert solar energy into . The leading PV companies have been full spectrum solar providers developing the PV cells, designing and manufacturing the PV product, and internationally distributing their own PV products. In the past, PV companies have competed for strictly through technology, trying to generate more electrical power in less space. Only recently, has any attention been given to the integration of PV technology into buildings through aesthetics or usability/ease of installation of PV modules adapted for use on residential or commercial roofs. As a result, most of the available solar products are heavy, cumbersome, unavoidable conspicuous, aesthetic eyesores, and expensive wherever they are installed.

For the most part, PV companies market their products as power generators to people the ability to generate their own energy from their residential rooftop or commercial businesses. Industry has traditionally relied on the average homeowner or business owner to seek out a self-sufficient method to create this electricity. Most solar products require a professional custom installation, increasing the costs, resistance, and aggravation of installation.

Aesthetics is generally a high priority for developers and homeowners in the market for a new . Conventional PV modules are generally arranged in thick raised boxes with a shinny outer surface. In addition to being conspicuous, conventional PV modules require a separate installation requiring the user to drill holes or other attachment means to the . Attempts have been made to include PV technology in an “integrated” manner, but they have not been successful.

A need therefore exists to provide an integrated solar roofing system that addresses the above problems in adapting PV cells to commercial and residential roofs. In this way, the solar product could install like normal materials currently used throughout the world. The PV would be integrated into the currently used roofing tile or those similarly used and make part of the roof. It is also desirable for the solar product to allow for sections of the roof to be designated for PV or active while leaving other sections to be non-PV, or inactive . The non-PV would have a similar appearance to the PV , concealing the use of a PV system. Any area of the roof that is undesirable for PV generation would be covered with the visually consistent integrated solar roofing system inactive , removing the obstacle of seamlessly blending PV cells with an existing roofing product. Together they would create a functionally and visually integrated roofing membrane. The would be designed to fit current roofing material standards on size, method of installation, and building code compliance. There would be no need to drill holes in the roof nor would a professional installation service be needed, thereby dramatically reducing the installation cost while allowing the user to inconspicuously solar power.

To boost solar yield additional flat mirrored reflectors attached to the . In both cases Hot water panels and PV panels.

Synergy between solar & hydro power

May 13th, 2012 DriveTek

Interest in solar and hydrokinetic energy which generates power by using submerged or partially submerged turbines that harness the energy from flowing water is on the rise throughout the world. Renewable , governments and investors are increasingly becoming aware of river currents and the huge associated energy potential. Because hydrokinetic power generation relies simply on the extraction of energy from the natural velocity of water, these power can be placed into sources of flowing water with minimal or environmental impacts.

Our patented hydrokinetic technology is designed for use in river and ocean currents with horizontal / inclined axis 3D turbines with diagonal .

The core of our patented technology is both the 3D turbines design and jet turbine blades. The 3D turbine with diagonal inclined tapered blades operates very efficient in very broad range of water speeds and starts to rotate by itself at a very low achieving much better performance.

By 3D is harnessing much more flow stream energy in comparison on the well known prop / impeller turbines. In addition we find out that the speed of water passing near turbine blades impacts of the turbine efficiency significantly. That is why our new invented 3D turbines overcome theoretical limit without any ducts arrangements and/or other diffuser/co-fuser augmentations. Zero environmental impacts.

The turbines are inclined mounted on a catamaran/threemaran type hull or barge and partially submerged into the water flowing beneath the barge.

In an open-river setting, hydrokinetic power projects will have a capacity factor (CF) of better than 98% because power will be generated by using constant water current to the effect that it would be considered a “base load” plant.

The rotational speed of the turbine is very low, and can be stopped from spinning in a matter of seconds through automated fault sensing equipment and the turbine can be lifted out of the water and placed in service mode in under 5 minutes.
