I've received a ton of helpful feedback after putting out the Cleantech Venture Capital in 2015 presentation; thanks much to everyone for the thoughts and reactions. Glad to see it sparking some thinking and conversation out there, which is why I did it. I'll post a follow-up here in a while.

In the meantime, I'm finding myself spending a not-insignificant amount of time on two "extracurricular" projects lately, the Clean Economy Network (where I'm co-chair of the board of the CEN Education Fund) and the Cleantech Open (where I'm serving as the chair of the Northeast regional competition/organization, Ignite Clean Energy).

First, on the ARPA-E conference: one thing that struck me at the conference was how the exhibit hall seemingly was dominated by bugs and carbon-capture techs. Now, I'm glad that ARPA-E funds are going to tackle such difficult technical challenges, and I hope that someday there will be breakthroughs in these areas as a result.  

But it did drive home for me just how much I'm bothered by the disconnect between the strong efforts by...
