RA 240 SOLAR MAX Solar Heating System from Cansolair

Published on May 14, 2010 at 5:39 AM

Cansolair offers the RA 240 SOLAR MAX solar heating system. The energy output of this model is rated as 1200 to 2400 W and utilizes 31 W for the purpose.

This panel weighs 130 lbs and has a width x height x thick dimension of 44 inch x 85.5 inch x 4 inch and at the center the panel has a thickness of 8.5 inch. This panel has more irradiance level and angle of frequency to gain more heat per square foot area.

The RA 240 SOLAR MAX solar heating system from Cansolair utilizes a curved UV stabilized polycarbonate lens. This solar panel is sealed airtight to prevent fogging of the lens or mold and maintains heat generation without drop. This model works on forced convection solar heating principle. The core of each panel module contains 240 aluminum cans. This unit is capable of changing the air in a 1000 sq. ft. room within 1.5 h of charging and maintains an environmentally friendly the air level in the room by utilizing only 15 min of sunlight per hour.

The RA 240 solar unit draws 90 cu. ft./min of colder and heavier air from the floor level through a filter by utilizing a powerful fan. The drawn air is pumped through the first check valve, a tailor made collector core and pumped back into the room by utilizing the last check valve placed near the ceiling, thus maintaining the uniformity of temperature in the room. This heater model utilizes 115v AC wall outlet /12V DC 220V-50 Hz. Intl. as power supply option.

The new vehicle design by Christian Susana is a nice combination of car and a caravan camper. Christian has called it Colim (Colors of Life in Motion), which might not win many points on looks department, but still is quite useful given the kind of flexibility it offers. Colim caravan concept provides the advantage of detaching the front part if one does not have a usage for the home part. Design wise it reminds more of geometric shape, which one can say to be a welcome change from the regular designs, but the designer has really explored a possibility using different shapes which may pave way for better shaped cars.

The designer says : “The Colim concept – an acronym meaning ‘colors of life in motion’ – is an intelligent mobility concept which stretches primarily the bridge between caravans, camper, lifestyle and business. Dubbed a ‘lifestyle motor home’, the cockpit can be disconnected from the usable living space. The livable area is flexible, with individually applicable multi function modules. Designed for two people (max. four persons), the motor home offers the possibility to personalize its four mobile ‘walls’ according to the present life situation of the user. This flexibility is not only limited to the living area, but also features in the cockpit.”








Biosphere 2 was an attempt at creating a sealed-off, self-sustaining ecosystem of the kind astronauts would need for Moon or Mars bases, or for extremely long trips into deep space. The name implies that the Earth itself is Biosphere 1.

The $200 million venture was mostly funded by a Texas oil billionaire. With a lot of TV cameras aimed at them, the first crew was sealed up in 1991, but oxygen levels plummeted, crops failed, the isolated crew grew testy and weak, and no animals survived except abundant ants and cockroaches. It wasn’t long before outside food and fresh oxygen were quietly brought in.

After a flurry of mission changes and lawsuits, the complex just north of Tucson is now up for sale:

“This is not all about the highest bidder,” [general manager of company that owns Biosphere 2] said. “All things being equal, we’d certainly like to see an appropriate reuse of the Biosphere and associated buildings, but ultimately, it comes down to what the market will bear.”

I gather that some good science came out of Biosphere 2, and its certainly better to fail in Southern Arizona than halfway to Alpha Centauri. Still, Biosphere 2 may be best remembered as an especially bizarre example of America’s (and The American West’s) doomed utopianism.

It’s also a dramatic example of something I’ve mentioned before — the intimate and often troubling relationship between American space science and the mass media. I’ll do some exploring of that long history in future entries of the Monochord.

The island of Hawaii has been examined for its historical ahupuaa land divisions.

Download the zip file below and expand it to a KML file. Open the resulting KML file with Google Earth to see the Ahupuaa and Moku of the island. The data includes elevation contour lines and all streams and rivers. The file is large for Google Earth and can take some several minutes to be up and running.

For the last few years I, with the help of others, including Jonathan Jay and the late Jean Ileialoha Beniamina, have been trying to identify the names and locations of the historic land divisions in Kauai Nei used by Hawaiians to sustainably manage land for centuries.Since this spring that work has been expanded to include all the eight main islands in the Hawaiian chain. The Western Pacific Regional Fisheries Management Council has contracted with to map the moku (bioregional) and ahupuaa (watershed) divisions throughout the state.On June 1st, 2010, we completed a submission that included the latest version of our maps of Kauai and Niihau. Since then we have been working on Maui Nei (Maui, Molokai, Lanai, Kahoolawe). On August 1st we will deliver that submission with a newly revised version Kauai and Niihau. We are scheduled to submit the Big Island of Hawaii on October 1st 2010, and Oahu on December 1st 2010.We will share the results on this website. An interactive GoogleEarth website embed of each island will be provided as well as a reproducible image.Research indicates that historically there have been changes in the mapping of ahupuaa. It depended not only on the cultural, historic and geographic knowledge of the cartographer, but the motivation behind doing the map.

It is likely that the need to manage resources increased as they were utilized by an expanding population. Certainly, over the centuries how they were managed changed. In time kapu (taboo laws) were enacted and taxes based on ahupuaa resources were collected.

After European contact, in the mid 19th century, the concept private property was accepted and it soon secured a foothold for widespread plantation agriculture. Water was diverted out of the valleys and the ahupua land use concept fell into disuse.

In some places, like Maui’s Hamakuapoko Moku (From the airport near Kahaluhi harbor to Haiku) the land was so aggressively managed by western plantation owners that ditches dams and reservoirs completely erased original streambeds. Hawaiian place names disappeared and subsequent maps of Maui had no Ahupuaa names. Instead we have Sprecklesville and Baldwin Avenue.

I have attempted to create a set of maps that have moku and ahupuaa covering all of each island. I have tried to use the earliest printed source material available as a foundation. I have tried to eliminate the distortions caused by conquest and war.

The boundaries for the land divisions is strictly based on topological features of the land: shorelines, streambeds, and mountain ridges. Like the informer Deep Throat advised Woodward and Bernstein to the bottom of Richard Nixon’s machinations; “Follow the money!” In the case of Ahupuaa that advice would be “Follow the water!”

Note: Depending on the island, it may take several seconds to a minute for the data to load.

These Kauai land identifications were delineated and converted to GIS and GoogleEarth KMZ format by:

Juan Wilson – Architect/Planner with the assistance ofJonathan Jay 

Samuel P. Kalama Maps (1837, 1838) of moku and ahupuaa were used as a foundation for these map boundaries. All moku and ahupuaa shown on Kalama maps are included in this project. The source for the 1837 Kalama map was the U.S. Librabry of Congress. The 1838 Kalama map was made available from the British Royal Geographic Society. Note, area names are written without traditional Hawaiian diacritical marks, as was the practice of Kalama. The divisions are based also on traditional descriptions of location, with boundaries modified to follow watershed ridges and streams/rivers from available topography.

After identifying Kalama ahapuaa and moko locarions and names the Aha Kiole Advisary Committee Final Report was compared with State of Hawaii DBEDT GIS files (Streams, water bodies and elevation contours) and added to GoogleEarth aerial photography and 3D elevation data to determine final ahupuaa and moku names locations and boundaries.

A two letter code for the sources of each ahupuaa can be seen when clicking within its boundary. They are:
