Aeroponics Vs. the Global Food Shortage
| April 9, 2012 | Posted by Craig Shields under Sustainability |
Here’s a short video in which I interview Tower Harvest CEO Rafael Quezada on the subject of aeroponics, a unique approach and capability re: growing produce organically, with a very minimum of space. This is a technology that can have a hugely positive impact on the coming global food shortage.
Teak Reforestation
| April 9, 2012 | Posted by Craig Shields under Sustainability |
We all hope that the investments we make grow over time — figuratively speaking — i.e., the asset value grows. In this short video, I discuss an investment opportunity that literally grows: your own grove of teak trees. I look at it as the ultimate in socially responsible investing (SRI).
Video: Sustainable Transportation
| April 8, 2012 | Posted by Craig Shields under Electric Vehicles |
Here’s a video in which I introduce a new 2GreenEnergy Associate – Dan Sturges, a senior consultant in sustainable transportation. As we sit here today, there are a few dozen of the world’s great cities that have extremely aggressive goals with respect to transforming the way their citizens move their bodies and their cargo — those who aspire to become beacons of hope and progress in this space.
While most state and local government groups are happy to maintain the status quo for as long as possible, thank goodness, that’s not true of all. And for these few forces of progress, Dan stands ready to help them wrap their wits around all the issues re: electric transportation, mass transit, car-sharing, incentives to encourage for walking, biking, ride-sharing, car-sharing, etc.
Video: Unique Approach To Hydrokinetics
| April 8, 2012 | Posted by Craig Shields under Hydrokinetics |
Here’s a video in which I speak to a unique approach and capability to hydrokinetics that applies in particular to large, predictable ocean currents like the Gulf Stream and the Mozambique Current off the coast of Eastern Africa. As I freely admit, there is no such thing as a free lunch, by which I mean all attempts at renewable energy come at an ecological cost — and ocean current is no exception. Having said that, and having studied more hydro-related ideas than I can count, I believe these guys have come across something extremely promising.
A Promising Player in Neighborhood Electric Vehicles
| April 8, 2012 | Posted by Craig Shields under Electric Vehicles |
Here’s a short video I made recently on a company in Michigan that I believe to be one of the most promising players in neighborhood electric vehicles (NEVs) aka low-speed electric vehicles (LSEVs). These guys have the design, the team, and the background to be quite successful in this space.
Hydrokinetics: Short Introductory Video
| March 17, 2012 | Posted by Craig Shields under Hydrokinetics |
In our continuing series of videos, whose purpose is to introduce newcomers to the subject of renewable energy, I offer this short piece on hydrokinetics, featuring a discussion of the strengths and weaknesses of the idea of extracting energy from moving water.
Though this sounds simple – and mankind has been harnessing that simplicity for thousands of years, it gets tricky now that there are seven billion energy-starved people on this small planet, and we’re desperately looking for sustainable ways of providing that energy.
Indeed, it’s not as easy as it seems. Anytime we insert a device into moving water, we face immediately a variety of issues, both ecological and logistical. I.e., we’re both changing the natural habitat in some ways that are hard to understand completely, and we’re also setting ourselves up to face huge costs associated with maintenance, as devices rust, and encounter things like biofouling, shifting current patterns, dynamic sea- and riverbeds, etc.
Hope you enjoy.
Pros and Cons of Solar Energy from Photovoltaics
| March 12, 2012 | Posted by Craig Shields under Photo-voltaics |
Here’s another short video for young people and newcomers to the subject of renewable energy. In this brief talk on solar energy and photovoltaics (solar panels), I provide my thinking on the strengths and weaknesses of solar power. Hope you enjoy.
Video: The Pros and Cons of Biomass
| March 7, 2012 | Posted by Craig Shields under Biomass |
Here’s another part of our series for newcomers to the subject of renewable energy — this one on biomass. I provide a few thoughts on how it offers the potential to provide carbon-neutral renewable energy and biofuels.
The Pros and Cons of Wind Power
| March 5, 2012 | Posted by Craig Shields under Wind Energy |
Here’s a short video I made explaining the basics of wind energy for young people, or newcomers to the subject. I explain why the wind blows, offer a brief history of man’s attempts to harness wind energy, and discuss our current efforts to use wind to generate large amounts of electricity with relatively little environmental impact.
