Say Hello to the Rocket Stove Heating System. In a Nutshell:
* Heat your home with 80% to 90% less wood
* Exhaust is nearly pure steam and CO2 (a little smoke at the beginning)
* The heat from one fire can last for days
* You can build one in a day and half
* Folks have built them spending less than $20
The YouTube video below was created/posted by the forward thinking engineer ZeroFossilFuel. In it he explains and demonstrates his most recent build. Not only do the less fortunate not need to freeze to death during hard times, but their energy use can be clean and efficient as well. A timely innovation to say the least.
From accommodation to cars, the internet is turning us from consumers into providers and challenging established business models. We talk to Martin Varsavsky, founder of Fon – the largest Wi-Fi company in the world – and profile two more pioneers, from TaskRabbit.com and BlaBlaCar.com
In 2006, serial entrepreneur and investor Martín Varsavsky – inspired by a conviction that he could cloak the world in free Wi-Fi by encouraging people to share their home connections – founded Fon in Madrid. The company is now the largest Wi-Fi network in the world, with almost 12m hot spots in more than 100 countries.
“My general thinking at the time was that we live in a world in which benefits are only accrued through economic growth and the endless consumption of resources, and that there have to be other ways that are of more benefit to people,” he says. “Why should everyone have their own car when most of the time they are not using them? Think of a marina full of boats. How frequently do those boats go out?”
Today, it has been argued that the sharing economy – which is perhaps best defined as a way of sweating underutilised assets, by building communities around them and turning consumers into providers – has the potential to reboot businesses across most economic categories. Indeed, Forbes magazine recently estimated that total revenues for the sector could top $3.5bn this year, with growth exceeding 25%. However, when setting up Fon, Varsavsky became convinced that people needed a nudge or financial incentive before they'd happily share their assets.
Speaker A: My friend is creating a wide-area radio network for Afghanistan.
Speaker B: Afghanistan has no infrastructure — including radio stations. Although radio is popular, it is mostly shortwave, with a few local FM stations for the local Iman. And electricity for radio stations is spotty at best including in Kabul.
Speaker A: Well, I can build really cheap, “ultra” cheap, radio receivers.
Speaker B: As long as you are doing that, why not give them OpenBTS cell phones running on ambient energy, and include a radio app? Then get someone else — Google, Virgin Mobile, the Chinese or India — to focus on all-purpose cellular towers and tethered ballons?
Part 4 of 6: Avaaz – Be the Change the Global Elite Want
by Gearóid Ó Colmáin / August 3rd, 2013
In 2006 another ‘democracy’ project made its debut throughout the world. The organization is called Aavaz. According to its website:
Avaaz—meaning “voice” in several European, Middle Eastern and Asian languages—launched in 2007 with a simple democratic mission: organize citizens of all nations to close the gap between the world we have and the world most people everywhere want.
Avaaz empowers millions of people from all walks of life to take action on pressing global, regional and national issues, from corruption and poverty to conflict and climate change. Our model of internet organising allows thousands of individual efforts, however small, to be rapidly combined into a powerful collective force.

Evolution does not favour selfish people, according to new research.
This challenges a previous theory which suggested it was preferable to put yourself first.
Instead, it pays to be co-operative, shown in a model of “the prisoner's dilemma”, a scenario of game theory – the study of strategic decision-making.
Published in Nature Communications, the team says their work shows that exhibiting only selfish traits would have made us become extinct.
. . . . . . .
Crucially, in an evolutionary environment, knowing your opponent's decision would not be advantageous for long because your opponent would evolve the same recognition mechanism to also know you, Dr Adami explained.
This is exactly what his team found, that any advantage from defecting was short-lived. They used a powerful computer model to run hundreds of thousands of games, simulating a simple exchange of actions that took previous communication into account.
The Rockefeller Foundation recently launched a major international initiative called “100 Resilient Cities.” The motivation behind this global project stems from the recognition that cities are facing increasing stresses driven by the unprecedented pace urbanization. More than 75% of people expected to live in cities by 2050. The Foundation is thus rightly concerned: “As natural and man-made shocks and stresses grow in frequency, impact and scale, with the ability to ripple across systems and geographies, cities are largely unprepared to respond to, withstand, and bounce back from disasters” (1).

Resilience is the capacity to self-organize, and smart self-organization requires social capital and robust feedback loops. I’ve discussed these issues and related linkages at lengths in the posts listed below and so shan’t repeat myself here.
Disaster responders cannot be everywhere at the same time, but the crowd is always there. The same is true for health care professionals such as critical care paramedics who work with an ambulance service. Paramedics cannot be posted everywhere. Can crowdsourcing help? This was the question posed to me by my colleague Mark who overseas the ambulance personnel for a major city.

So why not develop a dedicated smartphone app to alert bystanders when someone nearby is suffering from a Sudden Cardiac Arrest? This is what Mark was getting at when we started this conversation back in April. Well it just so happens that such an app does exist. The PulsePoint mobile app “alerts CPR-trained bystanders to someone nearby having a sudden cardiac arrest that may require CPR. The app is activated by the local public safety communications center simultaneous with the dispatch of local fire and EMS resources” (4).
