Here in Delhi, average October daytime temperatures are 34 C, or 93 F, and average solar intensities peak around 650 W/m2 midday. I personally lack any desire for a hot shower on days like these, and the black water tanks on our roof are essentially solar thermal heaters on their own. Still, the use of electric water heaters or gas-powered heating tanks in Delhi and cities all around the world are consuming large amounts of energy, energy easily and efficiently provided by the sun.
All of which makes the recent announcement from the Delhi government very appropriate and exciting! Solar water heating systems are now mandatory for all hotels, hospitals, nursing homes, and commercial buildings. Existing regulation has already mandated solar water heating systems for government buildings and residential buildings on an property of 500 square metres or more.
A mix of desert climate, high performance goals and the insight of a leader in sustainable design has yielded one of the first LEED Gold-certified straw-bale buildings in the world.
Utility bikes or “work bikes” are very efficient vehicles for transporting cargo (and children too). They are quite popular in bike-friendly places like Amsterdam, Copenhagen and China. Bikes can tow a remarkable amount of weight. Loads in excess of 880 pounds (400 kilograms) have been hauled behind bikes along flat surfaces. Generally though, 300 pounds (140 kilograms) is considered the upper threshold for hauling.
Japanese government officials want to start using the millions of wooden chopsticks that go discarded each year as biofuel. The chopstick biofuel (chop-fuel, bio-sticks?)is seen as a way to reduce dependence on Middle East oil and lessen the impact of global warming. Japan imports virtually all of its energy resources including oil.
The major advantage of the VIP over a normal pit latrine is that it comes with a ventilation pipe (covered with a durable fly screen on top) which reduces flies and odour. In the absence of other alternatives, the Ventilated Pit Latrine is considered reliable, which explains the success of this technology: over 500.000+ units of this type have been built in Zimbabwe alone and it has proven to work elsewhere around the world.
Homes spared in the wildfires in Southern California were in so-called “shelter-in-place” communities. They’re designed so fire goes around instead of through them, enabling residents to stay safely if there is no time to evacuate.
The point the [Berkeley School of Public Health] prof made was that as bad as the air is there, the particulate matter density of 200-300 micrograms per cubic meter (10x greater than average figures for US cities) is still less than the levels typically seen in biomass-burning homes in the developing world.
When it comes to finding a successful exit for your cleantech startup, good luck finding a buyer willing to pay the price you want. That was the consensus of investors at the Dow Jones Alternative Energy Conference this week. The cleantech industry is too young for its M&A market to have matured, and the IPO market, for certain sectors, is offering a lot better options.
On the CDC’s Director Julie Gerberding’s testimony before the Senate Environment and Public Works Committee on the “Human Impacts of Global Warming.”
“It was eviscerated,” said a CDC official, familiar with both versions, who spoke on condition of anonymity because of the sensitive nature of the review process.
The official said that while it is customary for testimony to be changed in a White House review, these changes were particularly “heavy-handed,” with the document cut from its original 14 pages to four. It was six pages as presented to the Senate committee.
The White House’s deletions included “details on how many people might be adversely affected because of increased warming and the scientific basis for some of the CDC’s analysis on what kinds of diseases might be spread in a warmer climate and rising sea levels.”
China’s interest in African oil has exposed its companies to increasing risk in recent months. Separatist rebels in Ethiopia’s remote Somali region killed nine Chinese workers in a raid on an oil installation in April. Chinese oil workers have also been kidnapped in volatile southern Nigeria.
The New York Times ran an interesting but rather incomplete article yesterday, discussing the split over anti-malaria bednet distribution strategies in Africa and the apparent demise of “social marketing” as a legitimate approach to reducing illness on a large scale. The article focuses on an ongoing debate in the aid community over whether or not insecticide-treated bednets, produced by Danish and Japanese makers and purchased by aid agencies, should always be given way in mass quantities for free.
If a single African country were to incorporate the best practices that are already in place across the sub-Sahara region, it would rank eighth worldwide. This was one of the observations that business leaders made last Friday at an award ceremony for the top two African reformers – Ghana and Kenya.
The nonprofit Worldwatch Institute has released a list of 21 “mega-cities” of 8 million people or more that are in direct danger as a result of global warming and rising seas
Progressive environmental policies sometimes come from unusual places like Uganda, which banned plastic bags in July of this year because they have become so problematic for the environment.
Now local and international NGOs are helping Ugandans in a suburb of the capital city of Kampala to collect plastic bags and turn them into items like baskets, handbags, shoes and roofing tiles.

On the weaknesses of solar cooking technology. I missed the first sentence or so of this, but he’s fairly spot on.
On the fallacy that new is always better.
Jock Brandis retells a story from Burt Rutan, famed aviator, that reveals a common misconception about technological progress: old is sub-par, new is better.
Architecture for Humanity, who we usually think of as working in distant locations, hits the ground running yet again. The local San Diego chapter is already hard at work with Rebuild San Diego, helping seniors and looking for anything and everything, from food, to toiletry, to bedding.
