remix on the libyans
I recently attended a fascinating seminar on emerging technology in energy. Here are some of my notes and thoughts on the next generation of energy:
My favorite new term. It refers to using existing energy sources (solar, wind, geothermal, thermo) and turning them into electricity to feed the grid. Pretty much covers all the new energy sources. Excludes coal, nuclear, etc.
Apparently, its just a dream.
Obama is pushing it and so is Energy Secretary, Steven Chu. All reasonable folk expect this is to be the foundation of our energy future. Without a modern grid we have no hope of utilizing the latest innovations. It would be like giving jet fuel to a horse drawn carriage.
Future, hah!, says the wizened gentleman behind me. He begins to explain his reaction after telling me he left the business and is only attending this seminar for nostalgia purposes. Suspect. He relates that the grid is already smart on a macro level. Utilities know how to share power, monitor, and get it to needed locations. What we are talking about is the micro level and involves pushing that technology to every city, home, and building. An expensive feat that will probably never result from government or utility spending.
More to be explained on that in following section.
What is a big deal then? Energy storage on the grid. If we are over-producing solar power in hot deserts and wind power at night, where will at all go. Our current infrastructure does not have an ability to use/transport/store this energy supply. If we can figure out a way to get the energy to high population areas then our grid will be smart.
This is where the real change is happening. Power outlets with remote controls. Home appliances with timers. Motion sensors. Sleep modes for computers.
All of these involve the new energy monitoring lifestyle. They give us an opportunity to take control of our energy use. A lot of us want more and this where smart metering comes into play. Hook up all those devices to a software package and you get data heaven. Charts, graphs, recommendations. This seems to be where the juice is (pardon the pun).
Google is offering a software package, called Power Meter, and partnering with Energy, Inc. Their product, the TED5000, has been flying off the shelves for over a year now. It appears that this version of the smart grid, one that is decentralized and at the individual level will be driving the market for years to come.
PV – Photo Voltaic
The process of converting solar energy into electricity. We all know about this and see it on many roofs. For many years the market has been stuck growing at a snails pace. New investments were needed to make this energy type economical. Now we are starting to see that and many seem to be surprised that the former ceiling of 20% (solar energy to electrical energy conversion) is being broken. Wikipedia tells us (with sourcing) that:
Photovoltaic production has been doubling every 2 years, increasing by an average of 48 percent each year since 2002, making it the world’s fastest-growing energy technology. At the end of 2008, the cumulative global PV installations reached 15,200 megawatts.
Second Generation PV
As the investments ramp up the technological innovation is booming. Folks with pent up projects are finally getting dollars (or more likely Yuan) to operationalize their theories. A big group of these innovations are centered around ultra-thin, low cost solar arrays. Instead of the bulky flat panels we will get complex micro solar panels with interesting features like: solar tracking (panels follow the sun), economies of scale (driving down cost), and mirrors (increasing efficiency through reflecting). Our presenter mentioned that these second generation panels have the capability to drive down costs to match that of nuclear and coal power.
Third Generation PV
This one feels more like a laboratory study than a real consumer product. Still their are companies releasing this on the market and our presenter even said that it is in calculators now. This grouping of PV focuses on the materials used to create solar panels. Searching for organic, nano, and molecular replacements for the raw materials (silicon, cadmium, lithium) that we use now. Definitely a major need since many of the raw materials used for solar panels are rare and sometimes for rogue states.
Touched on this a bit before. It boils down to a maximum reached by first generation solar panels. For many years their maximum solar to electrical conversion was 20%, with 80% lost/wasted. In comparison to coal and nuclear, which are 60-70%, this makes solar 3x as expensive and require 3x as many panels/turbines/etc.
The 2/3rd generation technologies mentioned above easily breach the 20% ceiling. One already at 35% through stacking panels, utilizing off band (UV) rays, and mirrors. I expect it wont be long until that number is doubled.
Not in my backyard. This is representing a real problem. In the coming years we will ‘plant’ thousands of solar panels and wind turbines. Few are happy to have them muddy up their roof or beautiful view.
Even worse this backlash is fostering more support for nuclear power plants. They don’t have to go in your backyard!
I just wish somebody would think long term on this. Nuclear Waste. Nuclear Countries. Nuclear Weapon. Not sure we need more nuclear in our lives, especially if the alternative is just a solar panel.
Maybe you have heard of DARPA, an uber-advanced military research group that created the internet, builds robots, and many other amazing innovations. the Department of Energy has created ARPA-E which stands for Advanced Research Projects Agency-Energy. A place to conceptualize and test the advanced energy projects of the future.
Wireless sensors presents a massive new industry of tiny sensors that require little energy. They serve a simple function which is to turn on, send data, and shut down. They only turn on when activated and gather a specific amount of data to transmit. After transmission they shut back down.
This allows them to be placed nearly anywhere and even form a mesh network. Activate one sensor that passes data and/or activation signal to the next one. In a few minutes you can have data from thousands of sensors. My brother wrote a dissertation on this using planes as an example. Place a sensor on all critical plane equipment. When the plane lands activate the sensors and get a status report on the plane.
Wireless charging is coming. At the recent CES it was the rage. Consumer products are on the market. An MIT startup, Witricity, has several patents and deals with government, industry, and consumables. Hooray for the day when we are free from our cable jungles.
A new material created in the lab with amazingly sophisticated microscopes that can be manipulated into a ridiculous array of uses. The presenter showed it as rope, tires, and even circuits. He passed around prints, stickers, rope, and cardboard made out of graphene. It appears to be the next gore-tex, or material than can be turned into anything. Cheap and moldable. It will be fun to see how this material is used.
Oddly enough I did it. I found a way that Green IT relates to Gov 2.0.
The bond too seems pretty strong on both sides. Almost as if one would be inherently weaker without the other. Read on…
My proposal to speak at Gov 2.0 Expo in May:
5-minute rapid fire presentation
Green IT for Gov 2.0
Description (400 chars):
Green IT is building momentum as our new Executive Order 13514 from President Obama calls for increased sustainability at every Federal Agency. This presentation provides an overview of the impact of this sustainability initiative, how it supports and builds upon Gov 2.0, and the best practices being employed in the government and commercial sectors.
On October 5, 2009 President Obama signed into action a broad forward leaning Executive Order focused on the environment, energy, and economic performance. The driving force behind this is not only climate change but a need to lower costs.
Strangely, this push is leading us directly into the cloud and on virtualized machines. These changes represent the latest in industry standards and extremely cost effective options for Federal agencies. Add in that it meets the requirements of the Executive Order and protects the environment, and it may just be an unstoppable force.
Parallel to these efforts, the Gov 2.0 movement is gaining momentum and is a surprising ally. The drive towards citizen engagement, transparency, and web applications rely deeply on this technology. It also presents a unique sandwich for success with IT driving the push towards cost savings and users/public clamoring for more openness.
Join me as I briefly touch on the major topics of this intersection of two fields presenting a broad overview, touchpoints between the two, and best practices to keep us going forward.
**If requested, I can pull together a panel discussion with relevant members of the commercial and federal sectors.
