Check this bad boy out.
Someone asked me how long it will take to get a positive return.
My response was; I really don't care. This is off grid, and a necessary stand alone back up. Everyone should have one.

How many do you need to power your house 24/7?

Temporary and low power. But it might work if the lights went out and you rolled it outside and rolled your refrigerator outside to plug into it. It might run that until an hour or two after the sun went down.

10 12 v batteries and a 12 v panel to charge each of 'em. inverter to 110v. No problem. Propane refrigerator/cook stove, geothermal AC, and wood stove for heat and you are set. Will pretty much run the rest so long as you don't have deep clouds for days on end.

MHT, That thing is a bit pricey for a large computer UPS with a solar panel charger. It is not going to run your house.

Look how much CO2 is released over areas that are not populated.

Kangaroo flatulence research points to new climate change strategy for farmers
New analysis of kangaroo farts suggests their low methane levels could have implications for farmers in the fight against climate change.
It has long been known that kangaroos – unlike sheep and cattle – produce little of the potent greenhouse gas methane.
For some time, researchers intent on breeding less windy flocks and herds hypothesised kangaroos might have a unique mix of micro-organisms in their stomachs that produce less of the gas.
The hope was by transplanting these micro-organisms, cattle and sheep might produce less methane.
But new findings suggest otherwise, and should help refocus sheep and cattle research on alternatives that might yield results.
The experiment saw red and western grey kangaroos kept in comfy, sealed chambers, allowing researchers to analyse the mix of gases going in and coming out.
“We think that the methane is low because of the way food moves through the kangaroo stomach, and not because of a unique gut fauna,” study author Dr Adam Munn said.
The battle for less windy livestock is a serious issue when it comes to climate change.
In the year to March 2015, agriculture accounted for 15% of Australia’s greenhouse gas emissions. The agricultural sector is the nation’s dominant source for methane.
Munn says more research needs to be done to work out the contribution various species make to greenhouse gas emissions.

Global Floating Solar Panels Market to Witness 116% CAGR During 2015 - 2020
The global floating solar panels market was valued at $3.89 million in 2014, and it is expected to grow with a CAGR of 116.1% during 2015 - 2020. The factors driving the growth of the market include increased government initiatives and stringent environmental regulations, no need for acquisition of large land areas, and increased efficiency of power generation. The rapid depletion of fossil fuels and global warming caused by their usage has shifted the global interest from conventional energy to green energy. The different governments across the globe have initiated several projects and schemes to promote and encourage the generation of renewable energy. With the advent of floating solar technology, several countries such as Japan, the U.S., the U.K., France, Australia, India, and Brazil have started taking initiatives to develop floating solar power plants. Many of these countries are providing direct capital subsidies and tax benefits to the manufacturers of solar panels. Based on product type, the stationary floating solar panels accounted for the larger share in the global floating solar panels market in 2014.
Geographically, the Asia-Pacific market accounted for the largest share in the global floating solar panels market in 2014. The floating solar panels market in Asia-Pacific is growing mainly, due to increased government initiatives in promoting the usage of floating solar panels. The installation of ground-based solar systems requires large land, the acquisition of which increases the cost of solar power installation. Therefore, floating solar panel technology and presence of abundant water bodies (such as ponds, lakes, rivers, waste water bodies and industrial effluent ponds) are creating ample growth opportunities for the solar panel industry in Asia-Pacific during the coming years.
The floating solar power plants have higher efficiency of power generation, as compared to the ground-mounted solar plants. The ground-mounted solar panels have reduced efficiency, due to the heating up of ground. Solar panels have improved efficiency at low temperature. Therefore, floating solar panels are more efficient, as water helps to lower the temperature of the photovoltaic panels. The increased efficiency of power generation by floating solar panels attracts high investment from major manufacturers and government, which is driving the growth of the global floating solar panels market.
The key companies operating in the global floating solar panels market include Novaton AG, Ciel & Terre International, DNV GL AS, Infratech Industries Inc., KYOCERA Corporation, SPI Solar, Pristine Sun, Yingli Green Energy Holding Company Limited, Trina Solar Limited and Sharp Corporation.
