Adventures in Ocean Hydrokinetics
I had a nice chat with my brother yesterday during which he asked my opinion of a company called Hydro Alternative Energy (HAE). Looking at their website just now, I notice they write: (Ocean) currents can be thought of as …
Run-of-River Hydro Projects in Southern Brazil
Each month, I submit an article for publication in the “Hedge Connection,” a marketing platform for hedge funds and an information portal for investors, in which I extol the virtues of one of our renewable energy investment opportunities. Here’s this …
Brazilian Politics Looking Better than Ever for Renewable Energy
Of all the renewable energy investment opportunities I’ve come across over the last couple of years, the collection of small run-of-river hydro projects in Brazil is possibly my very favorite, as the collection is enormous, and the technology is arguably …

Attracting Private Capital to Cleantech Start-ups
The world of private capital isn’t in a horrible hurry to invest in cleantech start-ups–especially those that represent some level of technology risk. What’s interesting is how the entrepreneurs behind these new companies are thinking and behaving as a result. …

Pelamis–A Developing Concept in Wave Energy
I try to keep track of the major ways of extracting energy from ocean waves, one of the front runners of which is the Pelamis, a long, multi-segmented tube that changes shape, creating hydraulic pressure, as the waves pass beneath …

Brazilian Run-of-River Hydro Projects
Ironically, of all the renewable energy investment opportunities I like, the one that’s attracting the most interest over the last week or so is my collection of 20-or-so run-of-river hydrokinetics projects in Brazil—despite the World Cup. Apparently, the whole country’s …
“DamNation” Examines the Legitimacy of Hydro-Electric Dams
The movie “DamNation” is screening tonight at a local church. Though I haven’t seen it, I know enough about it to summarize it as follows: Damming up our nation’s rivers has come at a vast environmental cost, and it’s time …

Discussion of the Costs Associated with Marine Hydrokinetics at the Ocean Energy Show
My major concern about the viability of marine hydrokinetics (MHK) is that there is very little attention paid to the levelized cost of energy that it represents. Is there a real trajectory for getting it in line with other forms …
