Biofuels May Hinder Anitglobal-Warming Efforts

Read an interesting article a couple weeks back in the WSJ on how biofuels may actually increase carbon emissions in the medium to long-term. Apprently the shifts in land-use necessary to support the production of bio-materials like soybeans, corn, or palm could in fact release more carbon emissions. The time it takes to get carbon-neutral on some of these projects is pretty crazy - 319 years for soybean biodiesel from Brazil (assuming you're clearing rainforest), 93 years for corn ethanol from the U.S. (assuming you're clearing grasslands), 86 years for palm biodiesel from Indonesia (assuming you're clearing rainforest). I suppose biofuels really aren't meant to reduce carbon emissions, but just crazy that they potentially exacerbate the problem so much.

If you do stupid/extreme things to produce biofuels like clearing rainforests, you certainly run into these issues. But there are plenty of other ways to ramp up production that are much more environmentally sensitive.

In the end doesn't it seem like solar cells will eventually be a better converter of sun than sun->plant->biofuel?

The Fortunate 400

So there's rich, and then there's super rich. I recently read an article in the WSJ about the top 400 taxpayers based on income. Pretty incredible statistics. Those top 400, or what they call the "Fortunate 400", pulled in $85.6 billion in income in 2005. That's over $200 million each ... in one year! Here's a quick graphic to drive that home: Very impressive. There's all the obvious jaw-dropping statistics to go with that. For instance, to make the cut to be in the 400 you had to pull in at least $100 million. With an average of $200 million, that means there's people pulling in well over that number. Obviously, quite crazy numbers, and generally speaking not necessarily anything to be concerned about. I'm all for capitalism. But one of the more disheartening statistics was that adjusting for inflation, the minimum income to make the cutoff into the Fortunate 400 has nearly tripled since 1992. That's probably not a good sign as I imagine that...

Dancing on the Edge of a Volcano

I found this opinion piece ( Democrats aren't innocent bystanders ) interesting on how both Democrats and Republicans share responsibility for polarizing the electorate and undermining some of its faith in democracy. It references two other posts that were pretty good as well: The Disease of Delegitimization The Weimarization of the American Republic The second article is really long and heavy on history.  But given all of the comparisons people make between the current times and those of post-WWI Germany, I found it interesting to dive in to understand where the comparisons are coming from and how close we really are.  The short answer is that we aren't that close (phew). Seems like post-WWI Germany was incredibly fragile.  This was a good excerpt that summarized it: So, unlike the 60s, you have a dynamic in which both sides are behaving like radicals, in which the establishment isn’t yelling “stop,” and in which oikophobia is more evenly distributed, relative to its Boo...

Nine Prescriptions for Building the Duke Entrepreneurial Community

I think Duke can have one of the strongest entrepreneurial communities in the world. Are we there yet? Well, not yet. But there's a tremendous amount of momentum that I saw build in just the past two years while I was getting my MBA at Duke. While leading Duke's 10th annual business plan competition, the Duke Start-Up Challenge (DSC) , last year, I witnessed a near doubling of participation on campus in just a single year. The interest on the ground was clearly there and building rapidly. But now that I'm an alum, I'm looking back and wondering ... how do we rev-up the Duke entrepreneurial community even more? I read a great article by Daniel Isenberg, a professor of management at Babson, called " How to Start an Entrepreneurial Revolution " in the June edition of the Harvard Business Review. Isenberg outlines nine prescriptions for governments that want to create entrepreneurship ecosystems in their countries. Although he was focused on governments an...
