Ocean Wave Energy Machines Have More Potential Than Some Would Like To AdmitHere’s a thinly guised attempt to ridicule the idea of government subsidies for renewable energy generally, clothed in a report on a failed company with a huge device to extract energy from ocean waves.  Obviously, the burden of proof of the cost-effectiveness of any technology lies on the shoulders of the developers, but I support the concept of government’s helping with the R&D costs of many different clean energy concepts, as long as they make some level of sense.

In particular, this basic technology, i.e., a multi-segmented tube that articulates based on the moving waters on the ocean’s surface, is not altogether doomed to failure.  In fact, we have one on our list of clean energy investment opportunities; it’s this one right here.  At scale, the levelized cost of energy (LCOE) can be very competitive.  And keep in mind that these devices are especially useful for bringing electrical power to operations at sea, where the practice of bringing in diesel to run generators is both expensive and environmentally hazardous.

 

 

Super-Concentrated Solar PV – Looks Like a Breakthrough HereHere’s an article about a breakthrough in super-concentrated solar PV from IBM researchers in Europe.  Incident sunlight is focused from a large parabolic mirror onto a semiconductor chip, producing electricity.  What’s new here?  Well, the concentration rate is 1000:1, meaning that an incredible amount of heat is generated simultaneously, which the team is able to capture and use for another purpose, e.g., water desalination.  The overall efficiency is over 80%!

I was happy to note that the fellow in this video is encouraged by the same basic fact that I often quote: At any given moment in time, the Earth is receiving 85,000 terawatts of power from the sun, while we’re using only 15 terawatts in the sum total of all our applications – about 1/6000th.  It’s there for the taking.

 

The Future of Transportation Comes Down To a Battle Between Photovoltaics and PhotosynthesisElon Musk says it better than I can (imagine that!).  Here’s his recent article on the folly of ethanol, in which he makes (and quite ably defends) the proposition that electric transportation will eventually win the day.  Why?  Essentially it’s the relative efficiency of solar PV vs. photosynthesis.  (Of course, he could have thrown in wind energy, hydrokinetics, and geothermal as well.)

Our Utilities Deal with the Challenge of Electric Vehicle ChargingHere’s a good article on the relationship between the power utilities and the charging of electric vehicles.  The author’s position is that the presence of electric transportation adds flexibility for grid operators, enabling them to adjust the rate at which EVs are charged according to the real-time availability of renewable energy.

I agree that there is a wonderful opportunity to use EVs as a tool to integrate more renewable energy onto the grid that would have caused a problem in the absence of this storage capacity.  There is a problem the author is overlooking, however: For car owners, the availability of their vehicle is not a “nice-to-have;” it’s a requirement.  Telling EV owners that there is a chance that they won’t be able to use their cars is not a viable plan, if we expect electric transportation to take root.

I see this as a soluble issue, but it’s one that I think we need to understand and confront.

Sustainability Means Minimizing the Impact of Human Development on Wildlife -- But Exactly How Is That Accomplished?A friend stayed at our place Saturday night, whose brother, I came to learn, is involved with establishing wildlife and eco-system corridors in fast-growing sub-rural communities.   Here’s a fairly detailed piece he sent me that lays out exactly how his team and he minimize the impact that human development, with, for instance, the construction of new freeways, has on the many species of animals that may now be cut off from water sources and other important components of a successful habitat.

How to Make Your Moving GreenNobody likes moving. Regardless of whether you are moving to a better place or simply relocating, it is always a hassle – countless boxes, sorting, dealing with movers, planning, sorting again, then resorting after that, endless packing, even longer unpacking… The list goes on and on with very few, if any items one can look forward to except maybe for the pleasure of finally finishing it. It is not easy to minimize the cost and distribute the available resources in the most efficient manner. (more…)

Las Vegas Is Home To Huge Conventions on Renewable Energy – And Essentially Everything Else

Sorry if this comes across as out-of-touch, but I’ve never had any particular love affair with Las Vegas.  When I was consulting to IBM and one of  its joint ventures in the late 1990s, my team and I spent three days in Vegas – quarterly.  Yes, that’s 12 out of every 365 days for each of several years—in a place that has never impressed me.

I’m turned off by idiots flying in from all over the country to lose money they should be saving for the children’s education. (more…)
