Monday morning follow-ups

There have been a few odds-and-ends news items in the past few days that follow up on topics we have discussed here before. Thus, in case you missed them, check out:

• This news release from Frost & Sullivan describing the need for increased spending on water infrastructure -- a nice follow-up to this post linking to Matt Marshall's good article on the attractiveness of clean water venture capital investing. The Frost & Sullivan report indicates that water infrastructure spending in the U.S. is already a $4B market, and is growing as regulatory and sheer operational needs mount. The report specifically points to membrane technologies and water meter reading as key areas for growth.

• Matt Marshall also has a very interesting post on SiliconBeat today referring to this post on Vinod Khosla which itself linked to an interesting story at BusinessWeek's Dealflow column.

• Regarding this post on biomass energy, here's a timely announcement from the DOE and USDA that they are going to promote the use of biomass-generated hydrogen.

• As mentioned a couple of times (here and here), solid state lighting is an area of interesting innovation. Here's another recent CleanEdge article describing ongoing progress in that technology.

• Finally, Konarka continues to get more press coverage, following on these mentions here, here, here and here.
