October 7, 2006: National Tour of Solar Homes Day

Asestourlogo119 To kick off the Natural Energy Awareness Month of October, the American Solar Energy Society (www.ases.org) will be sponsoring the National Tour of Solar Homes on October 7, 2006.  A solar home tour will happen in most states on or near this date.  Depending on the state, the tour may (or may not) have modern homes, but this will be an excellent opportunity to get first-hand information on solar energy:  information relevant to the particularities of the state YOU live in. 

Del_junco_solar_residence To find a list of links relevant to the state you live in, click here.  The tour in Texas will be in Houston and costs a nominal $10.  This looks to be an awesome tour, and as of today, there will be 8 homes with various green features.  Here’s a link to the list of homes with pictures and a description of each sustainable home. 

This is an awesome opportunity for anyone thinking about retrofitting their house or building a new sustainable house.  Why not learn from the experiences of others that have already taken the green plunge?  They will be able to talk about solar power, solar heating, cooling, passive cooling, wind power, day lighting, and other various green building technologies.  The Texas tour includes access to all 8 homes, a guide book, and a free energy efficient light bulb.  I’m thinking of taking the 5-hour drive (from Dallas to Houston) just to see some of these places and learn about the tax incentives specific to my state. 

For my Colorado readers (and there’s a lot of you), my friend in the blogosphere, Tom Konrad, Ph.d., has some good info on what’s going on in that state.  Just an FYI…

Mini-Wind Turbines: Case Study on Payback, Breakeven, & Pricing

Archwind

I recently ran across an article in BuildingGreen.com about a new wind turbine concept. A company based in Monrovia, California, called AeroVironment has created “turbines on a parapet.” These 400-watt turbines are made to be placed in a row, attached to the parapet of a building. The AVX400 turbine, which will be commercially released in the Fall 2006, can come with a canopy—designed to protect birds. To give you an idea of the actual size, the rotors for these fans are 4 feet in diameter and install side-by-side on 6 foot centers.

Tower of (Solar) Power – EnviroMission

Enviromission_2 A few years ago, my brother sent me an email link to a couple hundred acres of land in the middle of Nowhere, Nevada. Seriously, it was the ugliest land in the world with no development—no lines, no fences, no roads? I told him that there was a reason the land there was selling for such a cheap price, and while I couldn’t put my finger it, I’m sure there was a real good one (like aliens or nuclear waste dumping). He said, “don’t be dumb, dude, land’s land, there’s always value in it.” Well, not really, but I’m starting to think this land might have been a good deal. Here’s why…

EnviroMission is on the verge—it’s tested and ready to go—of breaking ground on the world’s first commercial solar tower power station. Todd Woody from Business 2.0, did an awesome article on this technology. It’s so serious that a half-mile tall solar tower is in planning for China and EnviroMission is hunting for land in the Southwestern United States.

Here are some of the pluses: (1) there’s no fuel (no exploration, transport, disposal, smog, or landscaping costs), (2) you can put it in the desert and it will be perfect—no one will live out there anyway, (3) the primary cost is in the initial development as operating costs are minimal, (4) it produces enough energy to power 100,000 homes sans pollution or planet-warming gases, (5) as compared to wind farms, the sun is more consistent (in the right locations), and (6) a large version of the tower could produce energy for the same cost (or better) as conventional power plants. Oh yeah, it looks good, too.

Enviromission The cool thing about this technology is its potential to be disruptive. When you consider the costs of using coal, you can’t just think in terms of the purchase price (if you’re a commercial entity, the government, or public person). Why? Because there are hidden costs associated with things like coal: smog, mining deaths/accidents/health concerns, and transportation costs. With China and Australia on board with the solar tower, the global supply for other varieties of energy increases. They stop using coal as much as before. Ex: if China uses the solar tower instead of coal, then there’s more coal for other people to use. Coal will then get cheaper to use for those people that can’t use/afford the solar tower (or other alternative energy). My economics might be a little jacked, but I still think this will be an interesting business to follow.
