A crash course in changing the world.

The concept of Concentrated Photovoltaic (CPV) systems is to use low
cost optics to increase the light incident onto the very high
efficiency semiconductor solar cell material, thus reducing overall
cost of the system while increasing energy output.

The concentration factor, denoted by X, is a measure of the increased light intensity on the semiconductor cell. X equals
approximately the area of the optic collector divided by area of the
semiconductor solar cell. ZenithSolar system is designed to a
concentration factor of 1000 X.

The ZenithSolar optical dish is based on a patented design, utilizing multiple simple flat mirrors mounted on a plastic
surface. The molded plastic surface, divided into four quadrants, is
fixed onto a rigid, high precision metal frame assembled onto an
azimuth - elevation solar tracking system.

The concentrated solar radiation is reflected from each individual mirror onto an array of solar cells. ZenithSolar uses
field proven high efficiency multi-junction III-V solar cells.

In conventional CPV systems, the excess heat generated in the solar cell needs to be removed to avoid damaging the
cell and to maintain high efficiency of electricity conversion.
ZenithSolar utilizes the heat generated at the solar cell receiver to
provide usable hot water heating, improving overall solar power
conversion efficiency to 75%
One of the markets on which ZenithSolar focuses is gated communities. Real estate developers of gated communities are interested in providing
high quality and centralized services to the residences - including
electricity and hot water.

In a gated community deployment, each ZenithSolar module can provide the majority of the electricity and hot water needs
of a standard household. ZenithSolar is currently installing its first
commercial pilot at a gated community in Israel - called Kibbutz Yavne.


ZenithSolar has identified hospitality markets - including hotels, resorts, hospitals, and other vertical markets - as a large and
receptive target.

Due to the high and constant need for high temperature hot water in those markets - the ZenithSolar system has
been identified as an ideal clean energy solution for the hospitality
market. ZenithSolar expects to launch a commercial pilot site at one or
more hospitality location towards the end of 2009.

So what if production costs can be reduced and that way maybe with the money from donations or NGO it would be possible to install a few in some african villages, stressing the importance of taking care of the system and how it is helping them.

There is a lot of work with nano-inscribing cheaper materials in order to get as good or better yields of power from photovoltaic cells going on at the Berkley Technology department right now. Nothing solid yet but they're getting tiny incremental steps closer towards a photovoltaic cell that doesn't cost an arm and a leg.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
