Check out this clean installation and the following article on the rest of the town. A third of all the homes have PV power, and the community infrastructure leans toward high-tech renewables too.
This community leads by example. Take the tour. With financial help from a local farmers' co-op, basic PV systems provide power to fifty rural homes — RE doing what it does best. Guerrilla Solar 90 Guerrilla Every little bit helps! If the utilities were really interested in the common good, we wouldn't need guerrillas.
Until then — the more, the better. Will an EV work for your wallet? Space and experience requirements too. Things that Work! The Power Vent does its job well.
Homebrew 84 Battery Desulfator As the weakest link in the RE-system chain, batteries need all the help they can get. This do-it-yourself desulfator will help keep lead-acid batteries happy. Book Review Powering the Future Tom Koppel's book explores the history of the Ballard fuel cell— high technology and corporate soap opera.

It was modeled after Iowa Energy Center's statewide contest, which focused on energy conservation and efficiency, and replacing fossil fuels with renewables. He figured that with two contests, "local 4th and 5th grade students would have a double chance of winning. There were posters! It was an incredible experience to see this wonderful, creative, and inspiring artwork," John stated.

During this time, we've seen home renewable energy RE use grow from a few thousand early adopters to well over a quarter of a million folks worldwide. Almost all of these people are not connected to a utility grid.Bureau of Mines, Minneapolis, Minnesota 2.
The bacteria colonizing geologic core sections attached were contrasted with those found suspended in the groundwater unattached by examining the microbiology of 16 depth-paired core and groundwater samples using a suite of culture-independent and culture-dependent analyses.
One hundred twenty-two meters was continuously cored from a buried chalcopyrite ore hosted in a biotite-quartz-monzonite porphyry at the Mineral Park Mine near Kingman, Ariz. Every fourth 1. Groundwater samples containing unattached bacteria were collected from the uncased corehole at depth intervals corresponding to the individual cores using an inflatable straddle packer sampler. The groundwater was acidic pH 2. Attached and unattached acidophilic heterotrophs were observed throughout the depth profile.
In contrast, acidophilic chemolithotrophs were not found attached to the rock but were commonly observed in the groundwater. Sulfate-reducing bacteria were restricted to the deepest samples of both core and groundwater. The results indicate that viable but possibly inactive microorganisms were present in the buried ore and that there was substantial distinction in biomass and physiological capabilities between attached and unattached populations. Compositional differences between attached and unattached suspended in associated aqueous phase microbial communities may develop due to selective advantages conferred on some populations by attachment to environmental surfaces Attachment of individual bacterial cells of a single population has frequently been associated with substantial changes in cell physiology, although the direction of change for a given physiological parameter is not predictable and the causal factors of these changes are unclear Accordingly, several recent publications have described both structural and functional differences between attached and unattached bacterial communities in marine and freshwater aquatic environments 712 Although similar distributions of microbial biomass and activities in geologic media and groundwater may impact solute transport in aquifers 193343few studies have systematically compared the microbial communities in paired core and groundwater samples.
Studies examining the microbiology of core and groundwater samples from unconsolidated sedimentary aquifers generally have indicated a predominance of attached biomass 513161725 Therefore, it has been suggested that core is more representative of the subsurface microflora than groundwater 11417 However, numerical dominance of unattached organisms has been observed in some of these reports 540and differences in composition between attached and unattached communities are common to all of these studies 513161725 The studies cited above are not all directly comparable because there are differences in formation lithology, degree of nutrient enrichment, factors related to sample pairing e.
Given the constraints for interpreting current data regarding attached and unattached subsurface bacteria, it seems premature to limit the study of subsurface bacteria to core or groundwater alone. Under a stable set of conditions, it is probable that a dichotomy between attached and unattached organisms will be established 18 which may be reflected in significant differences in the functional capabilities of attached and unattached populations.
There is a particular lack of data from paired rock and groundwater samples from crystalline, fractured rock aquifers.
In order to evaluate potential differences between attached and unattached subsurface bacterial communities, we applied a variety of culture-independent and -dependent techniques to characterize core and groundwater samples that were closely paired in depth of origin from a single corehole in a biotite-quartz-monzonite porphyritic intrusive.
