SeeSaw Pump and Sodis
Gaviotas, Colombia has a seesaw pump that is similar to the PlayPump
They also have developed a pump that can increase the depth from which water can be pumped.
Sodis is a method of solar disinfecting water using simple recycled, clear plastic PET bottles. Fill the bottles with low turbidity water, expose them to sunlight for…

Adding a Coat of Paint
I've discovered the prospect of Electricity Generating Paint from EcoGeek.com
My invention supposes that this has been fully developed and methods have been created to turn the heat into use-able energy. Obviously, there could be lots of uses for this. I posted a photo early about solar panel roofing tiles. This paint may be a cheaper way. Maybe… Continue

Regarding water purification
Well, for disaster situations, I find the simplest solutions noteworthy. I remember a project by a physicist who went around the world trying to convince governments to print instructions on plastic bottles.
The procedure goes: put infected water in a bottle, put out in the sun for 5-6 hours, the water will be safe for drinking after the radiation from the Sun kills all the germs.
I just can't remember the guy's name.

Easter Holydays in 2020
My favorite holyday is easter. It all starts with my grandmother celebrating it every year and it was a time where all the family was together. For Christmas we divided to go and visit every other family celebrating, but for Easter all came to us, probably the only making a big celebration then.
For 2020 I'll like to keep this a tradition, maybe now shared with friends and random people who would like to join and make a nice party out of this holiday. My idea is to eat some…

LEARN3: Rema - Ethiopia's solar powered village, first in Africa
Power is a loaded issue here in Ethiopia, especially this week with the diaspora community raising concerns about the Gibe III damn project, which could threaten the livelihood of 500,000 people. The efficacy of this project is highly suspect. Even though Ethiopia desperately needs better sources of power, the government is content to shut off power even in the capital for profit. Last year, the capital was only… Continue

BP006: Mighty Minty Boost Ipod Charger (Act3)
This has been around the internet for a while now, and I've already told myself to make this device, but due to my hectic school schedule. It's not an original idea, I stumbled upon this one time I was reading my feeds.

After scanning the web, I found a group called SolarCycle. Founded by John Tilleman and Drew Durbin, this company has created a few innovations in the field of sustainable energy.
Their first product is a cone shaped solar cooker which would replace the wood burning stoves that many destitute communities now use. The team focused their efforts on the Pemba community outside of Mozambique. The reflective material used for these cookers is made from the recycled trash from the individual… Continue

Water Purification Water Crisis Learn4 part 2
My first blog posting was focused on non-crisis water purification--on technologies installed or procured before emergencies, productive in the long term (also could be re-purposed for crisis use).
Large-scale water crisis situations (hurricanes, floods, cyclones, tsunami, earthquake, etc.) require special innovations to ameliorate the critical lack of potable water, and offset or prevent the spread of disease.

Sunlight, Fuel Cells, and a 2020 'Snow Day'
The mobile dings gently. I groan but don't bother to pick it up. There's no one on the other end. It's 6am and the solar panel complaining; it's rearing to get cracking at another day of work but its covered in snow. If it detects anything less than 70% efficiency I don't hear the end of it. Have you ever tried negotiating with a solar panel? Doesn't go over well. Concepts like "snooze" and "another 10 minutes" aren't in its API.

Solar Powered Desalination
As the people grumbled against Moses, saying “What are we to drink?” he appealed to the Lord, who pointed out to him a certain piece of wood. When he threw this into the water, the water became fresh.
(Exodus 15:24-25)

Solar charger
First I tought about doing a solar charger for something that I use every day, like my cellphone. Then I started thinking about how to do it, so I asked to myself: where can I find a solar cell? The answer was very simple: from a garden solar lamp (You can't find solar cells in the stores in Mexico like in the states) like the ones you find in Home Depot.
Then, the only thing to do was to take the solar cell from the lamp, and - some how - put it on the charger. Shouldn't be so…

Solar Energy Collection from Our Car Roofs
This idea is a conceptual blend of the "solar backpack" and the car. The solar backpack puts solar panels on a backpack, which allows the collected energy to power up an ipod or cellphone. My idea is to put such solar panels on the rooftop of a car, with a wire running into the car. It could do the same thing: power these mobile devices as well as rechargeable batteries.

Some things to take into acount when doing solar projects
Over 10 years ago now I worked as a marketing manager in a solar energy company. We sold home installations for hot water, hot air and electricity. The hot air
systems comprised a metal box with a polycarbonate cover that had
some kind of black UV resistant matting inside it that got warm under
the influence of direct solar radiation. The hot water system was the
Daimler-Prince (I think!) system made of glass vacuum tubes that…
