(Goes good along with KM)

Sell solar power not panels, by installing cost free panels at the customers place. and charge only for the energy used

A rapid prototyper is a 3D printer that is able to fabricate three dimensional artifacts from a computer-based model. Project authors describe ’self-replication’, understood as the ability to reproduce the components necessary to build another version of itself, as one of the goals for the project.

excelent to reduce electric bills and remove all licence costs,

smaller, faster, better,

think corporate savings when buying a batch of these ones

Benefits:

Using arduino’s processing and other opensource tools to teach students about the basics of robotics, electronics and programing.

Of course they are always great toys for DIY and hackers.

Hint: It works for furniture as well

Basically a solar cooker harnesses solar energy to transorm it into heat, so basically after an initial investment its a cero cost solution.

There are 5 types of cookers and can be made from very lowcost materials and even prefab.

Humanitarian organizations use them to prevent deforestation and since they generate no smoke at all they also prevent child deaf and lung cancer caused by smoke inhaling in rural communities.

This offers a sustainable low-cost solution for temporary workplaces, camping or simply portable solution for furniture.

Mexico URGENTLY needs a creative approach to marketing in order to offer a refreshing option to bruteforce marketing.

Facts

• 50% of the world’s population lives in cities.^[6]
• 800 million people are involved in urban agriculture world-wide and contribute to feeding urban residents.^[7]
• Low income urban dwellers spend between 40% and 60% of their income on food each year.^[8]
• By 2015 about 26 cities in the world are expected to have a population of 10 million or more. To feed a city of this size – at least 6000 tonnes of food must be imported each day.^[9]

With the increasing costs of food, and the misuse of cropping lands for bio fuels, Urban Agriculture seems an obvious solution for importing food, which helps to generate employment and decrease costs, and reduce contamination produced to transport food across states and countries.

Any major technology or process that leverages the adoption of Urban Agricutlure and Horticulture will gain great economic and social value. From Guerilla Gardening and Local Markets to Urban and PeriUrban Crops.

There exists a great development and social opportunity for business in urban irrigation, distribution

In Mexico cities like Monterrey, Guadalupe, Santa Catarina etc, there are city wide local markets called Mercado de Abastos, yet they import from long distances and while they offer an open market solution (free prices) they operate under un-optimal conditions and are centralized.

For a deeper insight please read more at Wikipedias references its practically a whole argument in favour of urban agriculture systems, for economic and social development, including wellfare, health and pollution.
