UV Light to Sterilize Drinking Water in Africa

Using UV radiation is known to be an effective way to sterilize water. Why? Because the radiation kills the DNA of any living organisms in the water, thus making them unable to reproduce in the human body- or anywhere else, for that matter. The micro-organisms aren't dead, but they can't make any more of themselves!! Hahaha



And if you think about it, what do many of the African nations have plenty of? Well, I'm in Ghana right now, and I would argue that it is SUNSHINE. Plenty of UV… Continue

seawater), which will be enclosed in spherical greenhouses. Using… Continue

I picked an organization that was started in my own hometown called Water 4 Water. This organization raises money by selling plastic and metal water bottles to provide children in Africa with water. Thier organization is very inspiring and simple. A portion of thier profits go to the play pump mission in Africa. These play pumps are wells that are in the form of a children's playscape. When children play on the play pump, they pump water up from underground. These play pumps also offer a spot… Continue

LEARN1

"Don’t fight culture (If people cook by stirring their stews, they’re not going to use a solar oven, no matter what you do to market it. Make them a better stove instead.)" This rule is incredibly useful and can apply to almost any situation. You cannot simply exchange a people's previously used items for newer, foreign things; they…

2020 me

Ten years from now, I will be a lead game designer in a studio specialized in creating live action pervasive, roleplaying and alternate reality games. My personal goal as a designer will be to allways have some kind of message and story in our games. This way, we will have enabled the players of our games to experience various critical situations from many points of view and aslo to take action in order to change them.


In the process, I will have uplifted and enlarged the slovak…

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

Thinking Outside the Box and Into the Urinal

There's some things you hear and have a hard time really processing, and using urine as a source of cheap hydrogen fuel via electrolysis is far up on the list.



Quick stats: Potentially 90 miles to a gallon. Water takes 1.23 volts to be split and release hydrogen, while Urea only takes about .37 volts, making it more efficient for hydrogen production.

Driving to Create Water

Not long ago the US Military working in conjunction with TARDEC (Tank-Automotive Research, Development and Engineering Center) designed a system that allows Army vehicles to create perfectly drinkable water via the condensation of the engine exhaust system.



The system creates on average 3.5 gallons per day.



Imagine implementing this system world wide.



There are over… Continue

Government funded geothermal installations

Geothermal heating/cooling is a great way to regulate temperature inside buildings without using a massive amount of energy on the A/C system.

This is an example of what geothermal heating in a building would look like. The pipes are filled with a type of liquid that absorbs heat--so in the summer, unwanted heat is absorbed into the liquid and stored there. In the winter, the pipes draw heat from the earth around it to warm up the…

In 10 Years Time.

While the future is uncertain, and my vision of it more warped than that of a branch underwater, I will hazard to imagine. If we cannot imagine, and dream how then are we human?


In 10 years I hope to be a professor of philosophy. At the moment I am on track, I will be attending a MA program in philosophy at CSULA beginning this fall. Hopefully I will kick but and leverage myself into a PHD program, and finally a professorship.


How will I utilize…

You will never feel secure like

Worms fix the climate?

Act I

So, I was tasked to follow a hero of mine. Or rather a social innovator. Instead of choosing one of the many persons assisting in Africa, I picked someone who aimed a little higher. I decided to follow Aubrey de Grey, and his attempt to stop aging. Aging kills 100,000 people a day. It seems to me, that all things equal it is better if 100,000 people do not die.


Now there is the issue of birth, or rather how can we stop death, and maintain birth. This is a huge problem that…

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

New Power in 2020

When I think of 2020, I see solar power being the prominent source of energy in America. From working in sports, I

see many of the stadiums that go unused throughout the year as a major provider

of solar energy. Imagine if the

seats that were in those empty stadiums were able to capture the power from the

sun and send it back into the grid.

Not only would the…

Homemade wind power

So it's not completely new, but I would want to design my own homemade wind turbine. I've seen a couple people on the EVOKE network give it a shot, and I've found a couple website that have plans such as My DIY Wind turbine, TheBackShed.com and Instructables.



Where my idea would differ from these plans would be cost… Continue

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.

Where I will be in ten years.

Ten years from now I will be in a political job assisting with people in the midlands of South Carolina particularly the rural working class and farmers. As the class of people that feed the nation I find that it is imperative that we assist with making sure they produce as much food as possible. I would like to support local scientists as well that are leading in research on how to produce food more efficiently. I will also be participating in missions to foreign countries to help people with…See More
