Section 1 – The Social Venture
Agriculture today is financed much like any other big business: with a view of investment that only includes financial return. This approach, however, is limited in scope and leads to major negative environmental and social externalities. With few sources of capital available to smaller players in the sector, and with an increasingly competitive marketplace, large-scale agriculture is increasingly squeezing out smaller scale… Continue

The Ushahidi project is a platform which allows users to report important information by utilizing their smartphones. They can use video, pictures or text message to report the problems that are occuring in realtime. Ushahidi uses a filter so that they can plow through all the messages and find out what is really going on instead of having to go through the massive amounts of data that is transmitted on Ushahidi.

I thought of an idea where all the machines in a gym are wired to a central generator, or they each have a small generator attached, and the spinning action, the pulling and pushing of weights and all the effort exerted by patrons of the gym will go to create electricity.…

Please write back your thoughts and opinions, as well as any information that someone else could find useful!

Rural Peru needs to have water. Though 80% of the urban population have access to water in the rural areas the penetration of it is only 30%. This is a shocker because it deepens the inequality of development between rural and urban areas. What needs to be done is to get water to this populations and design the system so they can use it in an efficient way. For a long time we've been using water in a inefficient way and we need to stop making this mistake as we get water to populations that… Continue

Here is an interesting clean energy project for remote or small comunities. Toshiba 4S is a small nuclear reactor that can give 10 MW of electrical power to a small community.
It is currently set to be tested in a small community in Alaska. If successful, it could enable small communities to function off large grids and have a secure source of… Continue

As a farmer, I have noticed that cattle do weight allot, and move allot as well. Cattle take thousands of steps per hour and each step is worth upwards of 1 thousand points of pressure. But this pressure stays and goes quite fast.
My simple idea is to put small pressure plates under our barn areas. Make a plate slightly elevated from the ground via a spring (around 2-4 inches). Spread the plates out about 1-2 inches apart. Between these plates will be long rods going the… Continue

So, this is not a complete mission yet for me, but I am working on it. Damian
and I are making a mobile garden. We have seeds and soil and a long pot (sort of like a giant flowerbox), we are researching when to plant and what and when the last frost date is for the area (mid-may) and enjoying the awesome amount of knowledge available on EVOKE.
This mission has been interesting. I miss my mother's garden, and I love naming… Continue

"Innovation (often) comes from constraint (If you’ve got very few
resources, you’re forced to be very creative in using and reusing them.)"
I have realized that living in a very small house is not only cheaper, but it uses fewer resources. Living here has taught me to reuse things, make them multi-purpose and really focus on what`s important to own, and what not.
