    Well I was thinking of powering more of the property with solar and battery storage but apparently Green Theft is really growing here in WA. Apparently professionals are targeting properties when owners are out or away. One bloke went home to find his batteries gone after they opened a freezer and found everything rotting. That is bad enough but the theft of this equipment could cause the failure of water pumping to keep stock watered.catching the thieves is difficult as it is difficult to identify the stolen items.

    Here’s a glimpse of the future for everyone on the planet, this story below shows one way of electrical energy generation, be it as a stand-alone household system, for the manufacturing industry, or corporate office facility or whatever…

    This technology can use gas from many different sources, even gas from sewage treatments works and there is-a-shit-load of human waste worldwide literally going to waste. That’s just one unused source.

    New Apple Data Center to Include Fuel Cell Installation

    Apple recently released its 2012 environmental report, detailing how it plans to use fuel cell technology in the company’s data center in Maiden, North Carolina.

    The installation of a 500-kilowatt biogas-powered fuel cell project that supplies cleanelectricity to our Cupertino facilities helps us avoid more than 1.2 million kilograms ofCO2 equivalent (CO2e) emissions.

    Apple is building a fuel cell installation that, when online later in 2012, will be the largest non-utility fuel cell installation operating anywhere in the country. This 5-megawatt facility, located directly adjacent to the data center, will be powered by 100 percent biogas, and provide more than 40 million kWh of 24×7 baseload renewable energy annually.

    Fuel cells are an interesting technology and have great potential. There are still some technical issues that will prevent widespread takeup for a while though. Particularly in third world or remote applications. The most serious is that any impurities in the fuel will contaminate of the electrodes and rapidly degrade the performance. You need either a very pure fuel source or some pretty serious purification gear which adds to the cost and complexity. It also makes them hard for non-specialists to service and maintain.

    Advances are being made and this is certainly a technology to watch.

    Cheers

    The advances mentioned that are said to be in need to be achieved, have been made, overcome already. It’s the market that needs developing. The technology is here, it’s the cost and the scale of volume in manufacturing the needs to be achieved to bring the price down.

    Really, in the different forms of fuel cell technology this should be or will be affordable right throughout the 3rd world. This will be able to provide electricity, clean water and heat for cooking without the CO2 emissions of burning wood, coal, dung, or peat.

    There are particular forms of fuel cells that have self cleaning electrodes. There are fuel cells that work in dirty water, in human waste water, and with those the result of generating hydrogen and electricity from sunlight, the filthy water upon the splitting off of hydrogen the water is pure clean drinkable water. That is really something, clean water for billions of people without clean drinking water.

    Lifting billions out of poverty and unsanitary environments, improving general health are just some of the benefits of fuel cells.

    This is great, Nanotrees Harvest the Sun’s Energy to Turn Water into Hydrogen Fuel, two birds with one stone ya might say… Making hydrogen with energy from the sun while capturing CO2 in the process.

    Meanwhile at the Geneva Auto Show this week, regarding hydrogen powered vehicles, Toyota’s Didier Leroy head of European operations stated, “We are preparing to be able to produce tens of thousands per year in the 2020s”. Toyota will start selling hydrogen powered vehicles in 2015 with most other major car makers.

    I found this thoughtful article on nuclear power and its future in the USA. Evidently, the building of new nuke plants has become so expensive that they cannot be contemplated without subsidies and/or sweetheart deals on the sale of generated electricity. It concludes that nuclear power is only a step towards a low carbon future, not the magic bullet the world is looking for.

    Solar electricity is easy to install, but our economy is not really geared to take advantage of it. For a USA perspective, look at Rooftop Revolution: How To Get Solar To 100 Million Americans.

    In part, the author says:

    We could exploit the full potential of solar, but that would require [gasp] planning, and planning is socialist, so oh well.

    So true. The political divide in the States is currently so toxic that anything hinting at Government intervention is rejected out of hand by the looney Right, especially the Tea Party.

    Here in Oz, the looney Right actively discourages attempts to move us away from our addiction to fossil fuels and regards any move to internalise the cost of CO2 emissions into the business model of the emitters to be a Communist Threat To The Capitalist World As We Know It. How dare we consider charging a polluter for the right to pollute? Outrageous! Just ask Tony “Climate change is crapTM” Abbott.

    Here is a short article, describing an advance in the process of producing hydrogen through photosynthesis. Evidently, a novel use of cyanobacteria has resulted in producing hydrogen twice as fast as happens in nature. Commercial use is “sometime in the future”, but interesting nonetheless.

    An innovative company called Air Products will build a renewable energy plant in the U.K. that will turn landfill waste into hydrogen gas. The hydrogen gas will then power about 50,000 homes, also, refuel hydrogen cars at the Heathrow Airport.

    At Heathrow airport not so long ago a hydrogen refueling station was opened which provides hydrogen for the hydrogen fuel cell “black taxis” for the Olympic Games.

    By 2015 most major car makers will be selling hydrogen fuel cell cars. RNCOS – “As per our findings, a number of automobile manufacturing companies are planning to launch Fuel Cell Vehicles (FCVs) in the coming years, with a target of widespread commercialization by 2015.”

    Billingham rubbish-to-energy plant ‘to create jobs’

    A factory that will turn landfill waste into renewable energy is to be built on Teesside bringing jobs to the region, its owners say.

    Air Products will build the plant at the energy and technology business park, near Billingham, with operations planned to start in 2014.

    Around 700 workers will build the plant and 50 people will be taken on to run it, Air Products said.

    It is hoped it will create enough energy to power 50,000 homes a year.

    John McGlade, president of Air Products, said the site would be one of the largest renewable energy plants in the world.

    ‘International firsts’

    “Air Products has longstanding expertise in building and operating large-scale industrial gas and energy-related projects on a safe, reliable and cost-effective basis.

    “The facility will also create skilled jobs in the area and we are hopeful it will provide an indirect boost to the local economy through the use of local service companies, hotels and other businesses, ” Mr McGlade said.

    Work on the plant is expected to begin within weeks.

    Mr McGlade said the plant would divert 350,000 metric tons of non-recyclable waste from landfill every year.

    Stephen Catchpole, managing director of Tees Valley Unlimited enterprise zone welcomed the news.

    He said: “The area is famous for delivering and supporting large scale projects and international firsts – it is our heritage and our backbone.

    “Now further expansion into new technologies and renewable energy continues to make Tees Valley one of the prime centres for significant inward investment.”

    Here’s one example of a useful low-cost microbial fuel cell tech project, a toilet that converts waste to compost for farming and some electricity, designed for third world populations. This is mainly to address sanitation and environmental pollution of streams and groundwater, etc, rather than a major electricity generator. The electricity from the fuel cell provides for night lighting for the toilet.

    Useful for billions of people who don’t have a sanitary toilet nor a light, this is supported by the Bill & Melinda Gates Foundation.

    Here’s a lecture, by Dr Daniel Nocera on his artificial photosynthesis & alternative energy research, presented at Brookhaven National Laboratories.

    You might want to make a cuppa and settle in for a while it’s over an hour in duration. Interesting and detailed info on the energy requirements for the global human population’s energy future.

    Here’s another breakthrough fuel cell project for treating human or animal waste while generating power to run the treatment plant AND with the ability to produce excess electricity for homes and hydrogen for vehicles.

    MAJOR ADVANCE MADE IN GENERATING ELECTRICITY FROM WASTEWATER

    8-13-12

    CORVALLIS, Ore. – Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity.

    The new technology developed at OSU can now produce 10 to 50 more times the electricity, per volume, than most other approaches using microbial fuel cells, and 100 times more electricity than some.

    Researchers say this could eventually change the way that wastewater is treated all over the world, replacing the widely used “activated sludge” process that has been in use for almost a century. The new approach would produce significant amounts of electricity while effectively cleaning the wastewater Continued…

    There was an interesting piece on the news today about a new solar powered toilet the Bill & Melinda gates foundation is putting money behind. It converts waste into hydrogen which the goes through a fuel cell to produce power.

    I suspect it may be too complex to really work in the third world environment they are aiming it at but interesting nonetheless.

    Cheers
