true green planet
CARE and GREEN TECHNOLOGY is the best idea!The ability to bring new life to used materials has become more than just a good environmental stewardship; it has become big business. Recycling is more than just bottles and cans, it is making efficient use of all materials and closing the loop on a product’s life cycle. This is positively impacting our economy, making it important for all to recycle.
Going green is ultimately about efficiency--using fewer resources to achieve an even bigger result. If you can use green technology to lift your company to a higher market share, you will have reached your purpose without waste, and you'll be able to call yourself a model company in more ways than one.
Biosphere is the answer in cleaning up the garbage and delivering clean green energy and portable drinking water.

Bloom Energy founder K.R. Sridhar introduced his invention created to provide clean and economical energy to every home around the world. Surprisingly, the raw material for his electricity-generating fuel-cell system is sand, which is used to make wafers that are the core of the Bloom energy fuel cell.
The “Bloom Box” is a collection of fuel cells – skinny batteries – that use oxygen and fuel to create electricity with no emissions. Sand is baked into diskette-sized ceramic squares and painted with green and black ink to create the fuel cells. Each fuel cell has the potential to power one light bulb. The fuel cells are then stacked into brick-sized towers sandwiched with metal alloy plates, and subsequently housed in a refrigerator-sized unit–the Bloom Box. Oxygen is drawn into one side of the unit, and fuel (fossil-fuel, bio-fuel, or even solar power can be used) is fed into the other side. The two combine within the cell and produce a chemical reaction that creates energy with no burning, no combustion, and no power lines. The Bloom 100-kilowatt Box converts natural gas and air into electricity, producing water and carbon dioxide in the process. Almost a complete green solution.
Google, FedEx, Wal-Mart, Staples, and EBay are among the company’s clients, purchasing corporate boxes that cost $700,000 to $800,000. EBay installed five Bloom Boxes nine months ago which fuel approximately 15 percent of its San Jose campus and has resulted in savings of $100,000 to date. Sridhar admits that the units come at a substantial price, but hopes to reduce the cost by $2,000 per box by 2020.
Bloom Energy announced its plans to raise $150 million in sixth-round capital to establish a market for the Bloom Box. The company says it has booked most of this funding with Advanced Equities Investment with its planned Initial Public Offering (IPO) valued at $1.45 billion!
Of course, this enormous amount of money is attracting the attention of critics and competitors. Critics declare the process is nothing revolutionary—merely another version of fuel cell technology, continuously pursued by many companies over the decades. It is true that the Bloom Box may be more efficient than a conventional natural gas power plant in converting natural gas to electricity. However, critics indicate Bloom Energy has not disclosed enough information to prove its invention is as efficient as the high efficiency natural gas plants now in use around the world. There is also the question whether the Bloom Box’s current high costs can be reduced enough in future to make it economical.
The already low price of natural gas saw a 15% decline this week—an interesting side note since price drives the economy. The gas reserves found around the world are enormous and may keep price down, at least as long as the fracking process is profitable. At these prices, there is going to be more effort to use natural gas over other forms of energy.

FROM green diary
It hasn’t been a month since we told you about a Manhattan-sized ice chunk departing from the Greenlandic glacier for good. While we lamented over the irreparable loss at that juncture, now it’s time to take heart from findings of a joint US/Dutch team from the Jet Propulsion Laboratory, Delft University, which states that ‘Greenland and West Antarctic ice caps are melting at half the speed previously predicted’, and sea levels haven’t gone that high as well.
Researchers’ findings are in stark contrast to previous estimates that predicted an average rise of around 0.75 mm a year in global sea levels. Moreover, it was predicted that the Greenland ice cap and West Antarctica were melting at a rate of 230 and 132 gigatons a year respectively. Since the glacial isostatic adjustment was not done, the estimates proved wrong. Now, the corrected data collected from the GRACE satellites, GPS measurements on land and sea floor pressure measurements reveals the Greenlandic sea floor is sinking more than it did ever before.
COP
A Greek and a Danish scholar meet and exchange experiences, ideas and points of view
The Danish Institute at Athens and the Danish Embassy in Athens cordially invite you to a two-day event dedicated to a green future ..One of the most decisive mega-trends of the century is climate change. Climate change will affect
us all; on a European as well as global level. With the COP15 Conference in Copenhagen the world is approaching a tipping point:
- How will we tackle the problem of climate change, will we do it together and what are the consequences?
- Politicians as well as companies will have to act -- so will people. If we want to change the world to a sustainable future, we need to change certain habits and ways of modern life. How will we do that? Why will we do that? And will it cost us?
