Going With The Flow

In recent months, I’ve come across more work being done in flow batteries than I’ve seen in the prior decade. I’ve been known in the past to say that fuel cells are kinda like fueled batteries.  Well, flow batteries really are fueled-batteries.  A traditional chemical battery is one sealed system that charges and discharges chemical […]

Conducting Home Performance

“Home Performance” used to sound like something musically-inclined parents forced their children to do in living rooms. It’s catching on, slowly, for what it really is, and that is tightening up houses – with an ear for proper ventilation, humidity controls and other riffs on indoor air quality, and fuel-efficient climate controls. (There are geographic […]

Venturing Into The Future

Last week, I attended a breakfast hosted by the Michigan Venture Capital Association, at which the President of the National Venture Capital Association, Mark Heesen, made some comments and fielded Q&A about the state of the U.S. venture capital sector. Mark presented a mixed picture.  On the one hand, the VC industry is clearly contracting:  […]
