Video: Making your own biodiesel [MAKE Magazine]

How to make a small batch (around a liter) of biodiesel


Duration: 4min 3sec

Make your own backyard biodiesel. It’s easy to make a small batch that will work in any diesel engine. You won’t need any special equipment–an old juice bottle will serve as the “reactor” vessel–and on such a small scale, you can quickly refine your technique and perform further experiments.

There are a few videos in this post on how to proceed to the larger batches.

Video: State of the Economy [GOOD Magazine]

A rather dark and apocalyptic video/transparency from the folks over at GOOD Magazine.


Duration: 4min 7sec

If we’re addicted to oil, our twelve-step program should begin with admitting that we have a problem. As the price of oil creeps higher, finding new energy sources is more important than ever. But the search for alternatives, combined with environmental disruptions, is putting new pressures on other essentials like food. There are some things that are going well in the world. Right now, the economy is not one of them.

The doom and gloom music is “Genesis” by Justice.

Description
Social Capital Markets 2008 (SoCap08) brings together the entrepreneurs who want to change the world, and the sources of capital that want to make it happen.

Social capital. Doing well by doing good. Making money make change. Philanthrocapitalism. Whatever you call it, it’s the emerging approach of harnessing the power of capital to support a new breed of smart, innovative entrepreneurs committed to changing the world in big, meaningful ways.

At SoCap08, investors and entrepreneurs will:

  • Gain the insight to better understand and leverage opportunities
  • Build the relationships and networks to accelerate momentum
  • Join and build a community that’s part of something big, important—and growing fast.

Highlights of the event include:

  • First national conference bringing together the broad ecosystem of investors and entrepreneurs
  • World-class speakers, including investors, entrepreneurs, and the organizations who support them
  • “Social Capital 101” track for those new to this arena
  • Innovative “connection concierges” to help you find the people you most want to meet
  • Entrepreneur Showcase highlights exceptional organizations building sustainable businesses with an impact

Register

Update:

After the two days of structured sessions and receptions, there will be a special “open space” workshop day, designed to bring together all of those from the conference who want to coalesce around action. Participants in this followup “unconference” will be able to partner in real time with others from different arenas to determine what can be accomplished in the coming year.

Anyone can attend the 3rd day’s unconference for a nominal fee that will cover munchables.

Thanks @jerrymichalski for the extra info.

Video: Let's Switch to 100% Renewable Electricity [We campaign]

You’ve likely seen this ad from the We Campaign if you’ve been slavishly watching the Olympics (congrats Michael Phelps, Nastia Liukin, et al!). In case you haven’t…

Switch


Duration: 1min

The ad, entitled “Switch,” features Americans of all backgrounds – rural and urban, blue collar and white collar – making the change from fossil fuels to cleaner, renewable forms of energy by symbolically “turning on” a giant, 25-foot light switch.

Link of the Day 080208: MIT profs take us a bit closer to hydrogen energy storage method for solar

MIT researchers have made a discovery they claim will allow solar panels to make hydrogen and oxygen gas that can be stored and used to power a fuel cell when the sun is not out.
“MIT researchers have made a discovery they claim will allow solar panels to make hydrogen and oxygen gas that can be stored and used to power a fuel cell when the sun is not out.”

From MIT’s Technology Review:

Researchers [Daniel Nocera and Matthew Kanan] have made a major advance in inorganic chemistry that could lead to a cheap way to store energy from the sun. In so doing, they have solved one of the key problems in making solar energy a dominant source of electricity.

Daniel Nocera, a professor of chemistry at MIT, has developed a catalyst that can generate oxygen from a glass of water by splitting water molecules. The reaction frees hydrogen ions to make hydrogen gas. The catalyst, which is easy and cheap to make, could be used to generate vast amounts of hydrogen using sunlight to power the reactions. The hydrogen can then be burned or run through a fuel cell to generate electricity whenever it’s needed, including when the sun isn’t shining.

For you primary source loving types – their research paper’s abstract:

The utilization of solar energy on a large scale requires its storage. In natural photosynthesis, energy from sunlight is used to rearrange the bonds of water to O2 and H2-equivalents. The realization of artificial systems that perform similar “water splitting” requires catalysts that produce O2 from water without the need for excessive driving potentials. Here, we report such a catalyst that forms upon the oxidative polarization of an inert indium tin oxide electrode in phosphate-buffered water containing Co2+. A variety of analytical techniques indicates the presence of phosphate in an approximate 1:2 ratio with cobalt in this material. The pH dependence of the catalytic activity also implicates HPO42– as the proton acceptor in the O2-producing reaction. This catalyst not only forms in situ from earth-abundant materials but also operates in neutral water under ambient conditions.

Why this a big deal

  • A major limitation of solar power is that solar cells produce peak power for only a few hours during the day.
  • A major limitation to using hydrogen derived from water as fuel is how energy intensive hydrolysis is and the price and rarity of necessary catalysts.
  • Nocera’s discovery uses cheap, earth abundant materials as a catalyst and offers a distributed way of storing solar energy for use at night.

Bonus: Nocera is making the technology open source.

“I’m open-sourcing this to let everybody run with it,” he said. “My plan is that when people see it, they’ll see it’s easy to do and they’ll start working it.”
