The New York Times has the story. Foster City, Calif.’s Planktos is already working on a project in the Galápagos and the South Pacific. Planktos says corporations seeking to offset their carbon emissions under new treaties and regulations make need its services.

4Info creates SMS ad marketplace — Speaking of new advertising models, Palo Alto company, 4Info, has launched a test program for an SMS marketplace. Chief exec Zaw Thet tells us his is the only company offering a market place.

Jeff Nolan leaves Teqlo, a mashup company –The Silicon Valley start-up Teqlo just wasn’t ready to go to market, and chief executive Jeff Nolan explains his departure today. In remarks to us, the former SAP executive noted that companies delivering APIs as part of their offering find it difficult to make money. How will they share revenue? Moreover, for any of these businesses to achieve scale, as a platform, a significant amount of capital, “upwards of $60 million,” will have to be invested. Moreover, what happens when Microsoft, Google and Yahoo enter the area (indeed, Yahoo already has Pipes, and Google has entered with My Maps)? Not to mention SAP, Oracle and IBM, all of which are heading there too.

Venture capital performance turns positive — At least, according to the latest day released by Thomson Financial, for the period ending December last year. Overall, venture capitalists investing over the past five year years saw a 1 percent annual return each year — not very good, but positive for the first time since 2003. The only people losing money, according to the survey, are early/seed-stage investors who have been investing for the last five years. Everyone else is making dough. However, these numbers should be taken with skepticism. The data has long been criticized for being too rosy, i.e, not factoring in the results of firms doing so terribly that they’ve shut their doors. See table below for the performance of VCs over different time horizons.
