Start your car with 8 AAA batteries instead of one 12V car battery

Start your car with 8 AAA batteries instead of one 12V car battery

no, you cant actually start a car with 8 AAA batteries. Eight AAA batteries do add up to 12 volts, but they still can’t provide enough electrical current to run the starter motor. But that’s not the whole story. Any battery has a limit on the maximum current it can produce. To explain why, we have a model to represent a real battery.

Sitting at home in the summer heat, your mind may start to wander to that fancy new air conditioner. But when it comes to making your house comfortable and sustainable, prevention is better than cure. By prevention we mean simple retrofits that will set you on the path to comfort and sustainability.

From Trash to Homes – Building Earthships Outside of Bogota

My buddy Jeff and I recently spent a week volunteering with an organization called Los Tecnicos that is building a number of small, sustainable, off-the-grid houses about an hour outside of Bogota in a town called Choachi. These homes are constructed with predominately with salvaged and reused materials: tires with dirt pounded inside for the walls, plastic bottles packed with plastic wrappers and other assorted garbage to make bricks, as well as other salvaged goods.

Surface Color & Solar Gain: White is the Greenest Color

Surface Color & Solar Gain: White is the Greenest Color

The U.S. Environmental Protection Agency (EPA) says that for low-rise commercial buildings, the heat gain through the roof is about 50 percent of the heat gain for the entire building. This heat gain can be reduced not only by using more insulation but also by reflecting the sun’s radiation. The American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) states that the heat gain through a white roof is half of that of a black roof, and the heat gain through a white wall is two-thirds that of a black wall. Thus, in hot cli- mates, the walls should have…

Sustainable urban agrihood growing in Detroit

Sustainable urban agrihood growing in Detroit

This week, the Michigan Urban Farming Initiative (MUFI) revealed its plans for the first Sustainable Urban Agrihood in the North End.

Wait, an agrihood? It’s an alternative neighborhood growth model, positioning agriculture as the centerpiece of a mixed-use development. There are some agrihoods around the country, but in rural areas. This is the first within a city.

MUFI’s agrihood spans three acres on Brush Street, a few blocks up from East Grand Boulevard. MUFI runs a successful two-acre garden, a 200-tree fruit orchard, and a children’s sensory garden. They provide free produce to the neighborhood, churches, food pantries, and more.

What is a grid-tied PV system?

What is a grid-tied PV system?

It is a photovoltaic (PV) system interacting with the utility, with or without batteries, that uses a relatively new breed of inverters that can actually sell any excess power produced by your solar array back to the utility grid. If you are concerned at all about your utility rates going up and would like to do something to reduce your monthly electric bill, then a grid-tie solar system may be just the thing for you.  These systems are easy to install and since some do not have batteries for back-up, the lack of batteries in these systems means no messy maintenance or replacements…
