        <description><![CDATA[not only is it &quot;not new&quot; but i built a thermal solar collector back in Maine about 20 years ago with this absolute genius who had PV panels spilling their excess heat onto water heating tubes. It was simple, cheap, easy to build and the same size as hot water solar panels.Of course I have forgotten his name]]></description>

        <description><![CDATA[The technology is not 'new', just the application. When PV panels convert sunlight to electricity, the panels get hot, really hot. They are just using the 'waste' heat to generate hot water. How about giving us some cost figures ??? It would be nice to know if this can be economically scaled to a normal size home without going broke in the process. If the electricity generated must be converted to 120 vac, what is the size and cost of the converters, batteries, wiring, etc.. The limiting of use of solar on homes right now is cost, which the average homeowner cannot or is not willing, to absorb. Here in the NE, solar is limited by days of sunlight, snow, ice, etc.. In a perfect environment, these arrays work fine, but because of wx, limited sunlight during the winter, trees that shade, etc, are the economics there?]]></description>

        <description><![CDATA[Another semi-puff piece. Out of 2:38, it spent 1:10 showing us the factory operation. Cogenera probably uses IBM services.It was interesting to see the different technologies combined. Solar cells work at higher efficiencies with concentrated solar energy but that creates tremendous heat that must be removed, or the cells degrade quickly. Using a closed-loop system to do this and provide potable hot water is an ideal solution. It limits its usefulness to companies that can use all this hot water. I wonder if a Sterling-cycle engine could be added to produce electricity, too.]]></description>

        <description><![CDATA[fortcard/pmmrozinsky, obviously smartplanet dont want you to watch it and spread the word as they dont seem interested in providing a a Direct URL link to the actual video so you can download it and run it locally in VLC or whatever, which i always find rather odd with all the online PR video clips , just provide a direct download link and make everyone happier]]></description>

        <description><![CDATA[agreed , the model is interesting, we need some off the shelf retail unit's though for generic world use, and OC a micro universal 12vDC power plug kit to allow you to add more units as you wish, i could find a place for two or 3 of those tank's and mirrors in the back yard, although simple auto sun tracking mechanical units driven by small DC motor's and fitted with 11b/g/n wireless CPU SOC are still a pipe dream in end user costs today, shame.]]></description>

        <description><![CDATA[What's more interesting is the sales approach--they don't sell systems. They sell heat and power.    * Design: optimized for customer?s facility and operations needs.    * Construction: eliminating the need to make capital investments or manage permitting and contractors.    * Operations &amp; Maintenance: providing all necessary maintenance, upgrades, repairs and insurance.    * Incentives and Tax Credit Management: as system owner, Cogenra manages all filings for solar tax credits and government incentives.    * Metering and Billing: Cogenra meters solar output and bills monthly for the energy produced.    * REC Management: Cogenra manages the distribution of Renewable Energy Credits as agreed upon with customer.All of this makes a great deal of sense to business under current conditions. Maintenance of these systems is not something most maintenance people know anything about at this time, and facilities maintenance is often hired work for tax reasons.It also puts them in competition directly with the local utilities (in Wisconsin the power company has to buy power from consumers at retail, you can sell any excess power under those conditions.Power &amp; heat costs I write off as expenses, but a system has to be amortized and the actual lifetime cost is unknowable.Be nice to see this model in the consumer market, as system maintenance is a worry.]]></description>

Getting electricity from a windmill isn't &quot;new&quot;, and collecting rainwater isn't &quot;new&quot;.These are all great ideas, but they're not &quot;new&quot;.  It's only the methods, subisdies, and marketing that are &quot;new&quot;.Years ago, my dad's house, and many others, had rainwater collecting systems.
