Google’s Project Loon proposes internet distributed by hot air balloo

No, we’re not joking. Google is seriously proposing hot air ballon-powered internet access, and has already launched a pilot project in New Zealand with 50 testers trying to connect via a helium-filled, solar powered balloon. One of the Google[x] moonshot projects, there are a couple of videos embedded after the break explaining the issue, and the technology Google wants to use to address it. Project Loon’s playful logo reflects the custom designed antennas users will use to receive their signal from balloons floating twice as high as commercial airplanes fly. The signal goes from ground based antennas, up to the balloon, which use their high-altitude placement to broadcast much further than other methods. In the future, the company envisions cell phone users connecting to the balloons to extend service where none exists today.

According to Google, in “more than half” of the countries in the southern hemisphere and for two out of three people on earth, internet access is far too expensive. It’s trying to set up pilot projects in other countries on the same latitude as New Zealand, so interested 40th parallel south residents should forward this info to the appropriate officials immediately. Meanwhile, curious Kiwis can sign up to take part in the project on its website, or attend the Festival of Flight in Christchurch on Sunday to meet the team and learn more about it.

Tidal Power to Alternative transportation: Guest blogger Cliff Barre

From Tidal Power to Alternative Transportation: Revolutionary Ways We are Protecting the Environment
Designed to exceed environmental standards, these municipalities and companies are leading the way in green initiatives. From LEED certification to ingenious heating systems, each of these ideas is transforming the how people deal with the environment. Lowering carbon footprints and supporting greener building methods paint only part of the picture. At the heart of these initiatives is the desire to transform how we protect the environment and everything in it.

 

Alternative Transportation and Greener Tenants

 

Considered a revolutionary for its business model, Destiny USA has also implemented exceptional new designs within their buildings. Destiny USA, the hotspot for Syracuse entertainment, requires each tenant within their expansion to become LEED certified. In addition, Destiny has worked on promoting greener transportation methods. People who use electric cars can get the best parking spots. At these parking spaces, drivers will find charging stations for their car. In an effort to promote greener lifestyles, Destiny USA also has 200-bicycle rack space. Employees who want to bike to work can use specially designed shower rooms. The property is linked with the Creekwalk to make it easier to reach the pedestrian bridge across Hiawatha Boulevard. Each of these greener transportation methods is designed to lower the use of fossil fuels and creation of greenhouse gases.

 

Warming Households with Waste

 

In Salt Lake City, eight tons of carbon dioxide is saved due to sewage. After Hurricane Katrina, gas prices spiked and city officials had to find a way to lower costs. The alternative heating and cooling system they created was with the help of engineers from Sound Geothermal Corporation. This new system takes heat from warm sewage water. Then, the water warms a glycol and water solution. Once this is done, the solution is piped back to households where it heats the rooms. During the summer, the system works in reverse and heat from each house is piped underground. Overall, this heating method uses 40 percent less energy than its traditional counterparts.

 

Transforming Tides into Electricity

 

Manhattan has had to deal with an electricity shortage in the last few years, but New York City has found a solution. Through new underwater turbines, the city hopes to create enough electricity to power 8,000 homes. These turbines will be submerged near Roosevelt Island.  This new project relies on triple-bladed rotors that spin every two seconds. Every turbine produces 36 kilowatts for the Roosevelt Island Grid. When all of the projected 300 turbines are installed, the tidal power plant should produce a total of 10 megawatts of power.

 

These revolutionary ideas may have started with one city, one company or one idea, but they are spreading fast. The tidal power project in New York City will be used in Ontario and Seattle in the coming years. As these projects pick steam, they have the possibility of changing the environment and the world.

We find it tough to see the consequences of our actions over long time frames and particularly so when they are on a huge scale, such as those captured by satellite imagery – take a look by clicking the link here to the images from google.

Ancient Arctic was warm, wet, and green. What that says about the future.

A 1,000-foot core sample taken from a lake in Russia’s northeast Arctic documents a period when the region was 14 degrees warmer than today, but with similar atmospheric CO2  levels.

A NASA satellite shows the state of Arctic sea ice, seen here September 16, 2008. A 1,000-foot ice core from the Arctic’s Lake E suggests that the Arctic was heavily forested 3.5 million years ago, when carbon dioxide levels were similar to today.

  • The period the team has analyzed covers the first 1.4 million years of the record, when the region’s climate shifted from warm and wet to conditions that signaled the start of ice ages.

This period is of interest in part because the warmth persisted despite periodic shifts in Earth’s orbit that reduced the intensity of sunlight reaching the region.

Temperatures were high enough – about 14 degrees warmer than today in the warmest month of the summer – to suggest that the climate system is more sensitive to small changes in greenhouse-gas concentrations than the sensitivity estimates included in some climate models.

If that’s the case, as other paleoclimate studies have indicated, the models may be underestimating the amount of warming likely to result from increasing atmospheric COconcentrations, the scientists say.

The period also is of interest because it holds clues about the factors that drove climate from prolonged warmth into a cycle of ice ages – factors that will help researchers understand the role natural variability plays in the region’s climate and where climatic “tipping points” may lie.

The work “identifies for the first time a long, continuous story of that history from the Arctic and what I call the Arctic borderlands,” says Julie Brigham-Grette, a geologist at the University of Massachusetts at Amherst who focuses on the Arctic’s ancient climate, referring to adjacent regions. Dr. Brigham-Grette is the lead author of a formal report of the results, which are being published in Friday’s issue of the journal Science.

The research was conducted by a team of 16 scientists from Russia, the USGermany andSweden.

The evidence is captured in a 1,034-foot core sample the team drew from the bottom of Lake El’gygytgyn, known informally as Lake E. It formed 3.6 billion years ago after a meteor punched a crater in Russia’s northeastern Arctic. The crater filled to form a lake 7 miles across and some 560 feet deep. The area around the lake managed to remain ice free during the ebb and flow of continental ice sheets during the Pleistocene ice ages, allowing sediment layers – and the pollen and other climate indicators they contain – to build up uninterrupted for the last 3.56 million years.

The team published initial results from the Lake E core last year, focusing on the Pleistocene. This latest effort focuses on the climate from the earlier, mid Pliocene through the onset of the glacial cycles.
