Which country to focus on?
16 Replies

From the discussions and comments I've seen, there's been a general consensus we should be focusing on Africa, but I haven't seen a lot as to which country in Africa we should focus on, if any.  I…Continue

Fun in the Park with Cryptosporidium

This idea is a little rough, so please be kind, haha.



For World Water Day 2020, I am imagining having a costume contest. In each participating city, preferably near a public waterfront of some kind, people come dressed as their favorite water-borne pathogen. The contest could have several categories, such as "best overall costume", "best protozoa", etc. I would imagine this would be a good but not too serious way to educate people as to just how many water-borne diseases are out there… Continue

Getting Clean Water to Scale in Bangladesh

For my ACT4 post, I decided to write about Grameen-Veolia Water Ltd., a joint venture between Grameen's health and hygiene subsidiary and Veolia Water, a French company. Operated as a social business venture (similar to the joint venture between Grameen and Danone I would imagine) the water purification plant provides water to the area at a nominal cost, which helps to maintain the facility and plan expansion into… Continue

The Floating Oasis

While generally I don't like the idea of water desalination (I'm a fan of learning how to make the most of what's available instead of forcing the system to work for you) I recognize that at least in the short term it may become a necessary part of life around the world. To that end, why not try to make this process as benign as possible?



I found a company, Water Standard, who is trying to do exactly that. Their idea is to get a tanker-type… Continue

A Happy, and Renewable, Holiday Season

While I don't actually celebrate Christmas, I do enjoy the lights and all the festive decorations around my neighborhood. It has been some time since virtually all Christmas lights phased to LED bulbs, but even with the massive reduction in power consumption, when a couple million people decide to string out hundreds if not thousands of lights a piece, you have to get more energy from somewhere.



With the short days, solar isn't really an option. Fortunately, the winter season… Continue

Great blog posts thus far, David. I'm also interested in the idea of bringing renewable and sustainable energy to Africa -- I wrote in one of my own blog posts about the possibility of bringing fuel cell systems like the Bloom Energy Server to the continent. Can't wait to hear what other ideas you've got for us!

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
