DJ CAVEM : Green Hip-Hop

Check out the behind scenes video, by Denver, Colorado based artist, DJ CAVEM and his related music video:

Apart from youth outreach and his music, he teaches “Blue & Yellow Logic & Environmental Sustainability”:

The goal of Blue & Yellow  Logic is to teach urban communities how to support themselves and the environment with this sustainability project. No back yard plots here.  The gardens cover city blocks and provide enough food to feed several families throughout the year.  Here Cavem supervises a soil delivery to agarden managed by the Eastside Grower’s  collective. The project is gaining local and national attention.  Recently, Blue & Yellow Logic has made arrangements to develop gardens at the home of  Colorado Senator’s Michael Johnston and The Seanse-Elyri  Aquaphonic Grown House Project  in order to provide free organic food to the community.

Electricity from Exercise?

From NPR, a story about converting gym use to usable electrical energy.


If only all the speed and strength of youth could be channeled into power. Turns out, it can. Some colleges and universities have started converting energy from exercise equipment into electricity.

One of those schools is Drexel University in Philadelphia, where student power runs straight into their buildings’ power grids. Dan Simmons, director of recreation at Drexel, says a typical 30-minute workout on a treadmill can generate enough energy to hold a light bulb for 2.5 hours.

A company called ReRev has retrofitted cardio elliptical machines in a portion of the university’s gym to generate electricity for that area. The energy can be stored, so it’s not necessary for someone to pedal a stationary bicycle to keep the lights on. (…continue reading…)

GM Virus Solar Cells?

MIT reported on Monday that researchers have a used genetically modified virus to produce structures that improve solar-cell efficiency by about one-third.

MIT researchers said they have found a way to make significant improvements to the power-conversion efficiency of solar cells by using a tiny virus to perform detailed assembly work at the microscopic level.

Sunlight hits a light-harvesting material in a solar cell, which releases electrons that can produce an electric current.

The research of this new study is based on findings that carbon nanotubes can enhance the efficiency of electron collection from a solar cell’s surface.

Solar Powered Art – Craig Colorusso

A solar-powered art exhibit? It wouldn’t be the first time we’ve covered something of that sort on the vaunted pages of mnp, but it could be the coolest.

Creating the effect of an enchanted forest of singing trees, Craig Colorusso’s “Sun Boxes” installation can be walked through in a leisurely manner, or run through at full speed in a last ditch and extremely risky move to avoid the approaching enemy.

Sun Boxes is a solar powered sound installation. It’s comprised of twenty speakers operating independently, each powered by the sun via solar panels. Inside each Sun Box is a PC board that has a recorded guitar note loaded and programmed to play continuously in a loop. These guitar notes collectively make a Bb chord. Because the loops are different in length, once the piece begins they continually overlap and the piece slowly evolves over time.

Basically, I imagine this to be one harmonious but constantly changing, amplifying, and diminishing barrage of sound that keeps on rocking (God forbid it’s cloudy out). Although not billed as such, I find this to be a potentially very interesting and mesmerizing marriage of sound and mathematics. Plus, this ninja is from Beantown!

Craig will be at the IMA from March 18-20, for what we hope are 3 beautiful days. We recommend you wander amongst the enchanted sound-forest, put don’t pick the flowers!

We are all reliant on the sun. It is refreshing to be reminded of this. Our lives have filledup with technology. But we still need the sun and so does Sun Boxes. Karlheinze Stockhausen once said “using Short-wave radios in pieces was like improvising with the world.” Similarly, Sun Boxes is collaborating with the planet and its relation to the sun.

June Energy

Around the world, there are shortages of food and clean drinking water, but what you may not realize is that there is also a shortage of light for those dark nights in electricity-less areas. A group of students from the University of Michigan have come up with a solution: Emerald, a portable solar panel-powered device that provides 100 lumens of light and power for your electronics.

These engineering students founded the start-up company June Energy. One of the students, Abdrahamane Traoré, comes from Mali where he grew up doing his homework with a kerosene lamp in a poor village. The kerosene lamp doesn’t provide sufficient lighting–only about 60 lumens of light–and can be bad for health. Plus you have to continuously buy kerosene fuel for it which can get expensive.

Emerald will provide 100 lumens of light, a USB charging dock, cell phone ports, and a number of adapters. The device charges in only three hours in full sunlight. It can charge a smartphone in the same time it takes to charge by an outlet, and the device can provide light for eight full hours. The students hope to get the price to under $20. (Source)

Living Like Hobbitses

Yo, ninjas, what’s good? Me? Breaking wood and taking it to the hood, baby. Anyway, I just wanted to tell you to check out this joint I found about “Earth Sheltered Dwellings.”

These things are cheap, efficient, GREEN-as-all-hell, and, this being the most serious upside, they look like hobbit houses. Basically, the idea is you construct yourself a little home in a hole in the ground and just chill out and reap the benefits.  If you want 25 reasons to choose an earth sheltered home, follow the obvious link.

If you wanna learn how to do it yourself (and see some kinda-sick pictures like the ones in this post), have at it here.

earth sheltered homie

This earth sheltered home thing is, in a nutshell, the same as what the skunks do all year in my fenced off compost bin. And we all know that skunks are the ninjas of the rodent family. Word up!

Livin’ Off the Grid

Despite how kitschy this video is, the guy has a certain charm about him (I think it’s his tiny carbon footprint). Our friend here doesn’t make it look completely easy or anything, but still manages an amazing proof of concept design here. Not to be a fearmonger, or something, but I hope this type of design makes it to your ordinary consumer (read: Joe Six-Pack) before it’s too late!

Why another video, you ask? Well, why our resident green expert is on her mini-sojourn, we must keep the house tidy. Expect more and better to come soon.
