    Pest control without synthetic chemicals

    12-15 drops of Peppermint oil, 8-10 drops of Eucalyptus oil dropped into 0.5 oz dish soap diluted in 12 oz water spray bottle.

    Fragrant and strong! The soap + oils will help the scents remain in humidity and weather.

    Repels (low concentration of essential oils) or kills (in higher concentrations): Fleas, Ticks, Wasps, Spiders, Mites, Chewing Lice, Earwigs, Millipedes, Dust mites!

    Essential Oils can be obtained in quantity online, pretty easily:

    Peppermint Oil

    Eucalyptus Oil

    The Federal Aviation Administration is funding research to make this costly conductive concrete more affordable.

    This special concrete mix, studded with electricity-conducting ingredients, could help airports and other places run on time during inclement weather.

    "Potholes often originate from the liberal use of salt or de-icing chemicals that can corrode concrete and contaminate groundwater over time, Tuan said, making the conductive concrete an appealing alternative with lower operating and maintenance costs. The power required to thermally de-ice the Roca Spur Bridge during a three-day storm typically costs about $250 -- several times less than a truckload of chemicals, he said."

    Battling climate change with a partnership between public and private investment in discovering and developing breakthrough technologies is the aptly-named Breakthrough Energy Coalition

    While we'll never get people to stop burning wood to make fires for heat and light, and cooking -- we probably can help our planet out by finding better ways to stay warm, have light, and cook food.

    And let's not forget about powering our beloved electronics!

    "The existing system of basic research, clean energy investment, regulatory frameworks, and subsidies fails to sufficiently mobilize investment in truly transformative energy solutions for the future. We can’t wait for the system to change through normal cycles."

    Harvesting Water from Air

    Researchers in Bangalore, India have come up with a machine that can harvest the moisture from the air -- it works best in environments with 65 - 75 percent humidity.

    Sapling

    The fastest way to grow a forest; directions modified for an ecosteader audience / adapted from the source below:

    1. Test the soil's Ph to find out what what it lacks. Great soil has a healthy blend of Carbon, Nitrogen and Phosphorous -- all of which are generated from compostable materials.

    2. Identify what species should be growing in this soil, depending on climate. It does not need to be native.

    3. Acquire a locally-abundant biomass to feed the soil whatever nourishment it needs (may be an agricultural or industrial byproduct — like chicken manure or press mud, a byproduct of sugar production)  — but it can be almost anything. The less distance you have to haul the biomass the better.

    4. Amended the soil to a depth of ~one meter, plant saplings that are up to 80 centimeters high, packing them in very densely — three to five saplings per square meter.

    5. The forest itself be planted to cover at least 100 square-meters, minimum. This space grows into a forest so dense that after eight months, sunlight can’t reach the ground. "At this point, every drop of rain that falls is conserved, and every leaf that falls is converted into humus. The more the forest grows, the more it generates nutrients for itself, accelerating further growth. This density also means that individual trees begin competing for sunlight — another reason these forests grow so fast."

    6. Keep the forest watered and weeded for the first two or three years, after which it should become its own ecosystem and sustaining.

    7. Leave it alone -- allow that ecosystem to work. Not all will, but those that do do for a reason.

    It's like the DeLorean and the Tesla had a baby!

    Salt water-powered automobiles are a step closer to reality -- recently approved* in Europe.

    "The QUANT e-Sportlimousine features the revolutionary nanoFLOWCELL® energy storage technology – a further development of tried and tested redox flow-cell systems. The nanoFLOWCELL® sets itself apart from other systems in its ability to store and release electrical energy at very high energy densities. The very compact and powerful nanoFLOWCELL® battery system in the QUANT e-Sportlimousine prototype can power it for a driving range of up to 600 kilometres."

    "But when mayors and developers focus on technology rather than people, smart quickly becomes stupid, threatening to exacerbate inequality and undermine the social cooperation essential to successful cities."

    "After researching leading cities around the world, we’ve concluded that truly smart cities will be those that deploy modern technology in building a new urban commons to support communal sharing. Unfortunately, “sharing” is often too narrowly conceived as being primarily about economic transactions. The poster-children of the sharing economy are being co-opted by the interests of venture capital and its insatiable demands for rapid growth and high-value exit-strategies. "

    What can we do as community citizens to promote ecologically sensible urban planning projects in our communities?

    Sites like CitizenInvestor think they might have the answer. . . as highlighted by a recent post in CityFix

    What role should crowdfunding play in our cities?

    "By allowing citizens to donate small amounts of money to projects of their choosing, urban planning can become a more participatory and inclusive process. These platforms also open up a new source of capital for projects that may not otherwise be funded.

    However, civic crowdfunding also presents risks. While it can make planning more participatory, it may exclude citizens who lack the ability to make significant donations. Further, it is unclear whether governments will turn to civic crowdfunding instead of funding projects that should be paid for with public funds. Finally, most civic crowdfunding projects remain small, and it is unclear whether the model will effectively scale up.

    Still crowdfunding is gaining momentum around the world. While is it most common in wealthier countries, it also has strong potential for opening up new capital in middle and lower income countries. It is already growing quickly in India, where a variety of crowdfunding platforms are emerging to fund arts and business ventures.

    Crowdfunding is growing as a tool being used to fund a variety of projects, including investments in start-up companies, real estate ventures, and alternative energies. Still, these innovative funding models are early in their growth. In time, civic crowdfunding may help reshape our cities to be more sustainable and responsive to citizens’ needs and desires."
