Hey, Mark okayed it, so plugging your company must be cool! ; )

Shameless Plug for BeUtilityFree

Take the idea of energy sustainability and apply it to what are probably your largest energy uses: your home and car. That’s the approach of BeUtilityFree. Take a look at what we do at www.beutilityfree.com. (I’m the webmaster as well as a renewable energy installer, so I’d love to hear feedback on what you think of the site at brett_s AT BeUtilityFree.com.)

The grand plan is to start out by reducing the amount of energy you use through replacing your current fixtures and appliances with more efficient ones, or designing your new home with efficiency built right in. Then you can buy a much more affordable renewable energy system that will cover your modest needs.

Once you own your means of production, you start getting paid back through avoiding the ever-rising cost of fuel, selling renewable energy credits for your production, taking tax breaks and utility incentives and maybe even selling excess energy.

We sell energy-efficient appliances and lighting and renewable energy systems like solar electric, solar hot water, wind power, hydrogen cogeneration and ethanol stills. We’ll design renewable energy systems, install them or just sell the components to those who have the skills to set them up themselves.

Our special, can’t-find-them-anywhere-else items are Nickel-Iron batteries, the Superior Solar Storage Tank and our 3″ and 4″ column Ethanol Stills.

We are hoping to unveil a few exciting things in the near future. Among them are:

  • A turn-key ethanol plant. Just put feedstock, water, enzymes and yeast in one end and watch the fuel pour out the other. We’re currently testing enzymes for cellulosic production so that making ethanol can be as inexpensive and sustainable as possible.
  • A Purchase Power Agreement plan that lets anyone get solar energy from their rooftop without any up-front investment. We’d retain ownership of the solar system and sell you the energy at a rate lower than the utility company’s.

If we can get everyone to pump renewable energy into the grid or unplug and make their own energy sustainably, we’ll have taken a huge step toward getting this climate problem licked. And if everyone owns the source of their energy, we can all get out from under the thumb of the utility company and the US Oil War Machine and get back to making a poistive difference in the world.

Lonnie Johnson, the man who made “squirt gun” synonymous with inadequacy, is currently working on a prototype heat engine which would use heat from the sun to force hydrogen ions through a molecular membrane from a lower-pressure hydrogen chamber to a high-pressure one. If that made total sense to you, then you clearly have a lot more engineering under your belt than I do! For a more detailed explanation try this page.

The engine will be more efficient as the difference in temperature between the heat source and the heat sink goes up, reaching 60% at about a 600-degree-to-room-temperature differential. Achieving such a temperature is no problem for parabolic mirror solar thermal collectors, which can easily reach 800 degrees.

Johnson is hoping that a variation of his heat engine could generate electricity from the heat of an internal combustion engine or even from human body heat! Sounds like The Matrix could come true!

Their plan is to spur the development of high-altitude wind generation (a technology as yet untested), solar thermal electricity generation and geothermal power first, then other technologies later, with the final goal of making renewable energy cheaper than coal. Take a look at TheDailyGreen.com article for more.  And here’s Google’s webpage on the project.
I can’t wait to see where this goes, especially what with being employed in the solar industry. Now, if only the federal government would follow suit…

Why Haven’t We Thought of That? http://www.renewnews.com/2007/12/12/germany-mandates-heating-new-homes-with-renewable-energy-why-havent-we-thought-of-that/ http://www.renewnews.com/2007/12/12/germany-mandates-heating-new-homes-with-renewable-energy-why-havent-we-thought-of-that/#comments Wed, 12 Dec 2007 18:33:43 +0000 Brett http://www.renewnews.com/2007/12/12/germany-mandates-heating-new-homes-with-renewable-energy-why-havent-we-thought-of-that/ The Renewable Energies Heating Law just passed in Germany requires all new homes built after January 1st, 2009 to provide 14% of their heating and hot water energy with renewable sources. The German government is promising $517 million dollars a year in grants to help make this happen. Then, starting in 2010, existing homes will have to be remodeled to include renewable energy heating systems. There will be a lot of new solar thermal panels, heat pumps and wood pellet stoves and boilers installed over there in the coming years!

Israel and Spain began this trend (Spain also required photovoltaic energy systems in new buildings as of 2005–Wikipedia) and I sure hope we’ll be continuing the trend here in the U.S.!

Take a look here for more on the new law.

You can convert your VW into an electric car with the kits available at e-volks.com. It’s pretty amazing really. I read about this website in Make magazine, and it looks really cool. The guy in the article made his car not only electric, but solar as well, by putting a $350 solar panel on the roof. You won’t get the range that a factory-made solar would get (if they existed) but you can get enough range for most people’s daily needs.

Maybe it’s time to find that old VW and make it into an awesome car of the future! The site says that you can use the kits with other cars as well, it just takes a little more work.

It seems to me that with the new battery technology from this post you might even be able to make a car with better range than the one in the Make magazine article. By the way, the article is available online, but you have to have a subscription to read it. You might as well just join up if this kind of thing interests you; it’s an awesome magazine.

Gotta pay the bills:

The home security systems are used for the protection against any kind of burglary, fire losses, and accidental situation, caused by electric short cut. The most reputable and advanced security system is known as adt security devices which are used for the different safety measures. The brinks security systems and appliance are more reliable and affordable with the exclusive safety measures based on the advanced technology.

Of course I strongly believe that we need to put massive effort into making solar power and other renewable energy sources viable, but the truth is that wind is not constant and solar is not yet very efficient.  When compared to the massive amount of coal we as a nation (the United States of America) burn, nuclear seems to be the lesser of the two evils until we can get renewables to cover a greater percentage of our energy needs.  To be sure, I ONLY see nuclear as a stop-gap measure, but we need to take action now to decrease our national carbon emissions.

The Venturi Company from Monaco is hitting the renewable energy vehicle market full-force. They have three different models already: The Eclectic (a golf-cart looking super eco-car; below), the Astrolab (in between a sports car, and a an eco-car; above), and the Fetish (all-out sports car).

Only the Fetish is in production at the moment, but all of the cars will be limited productions even when they are in full-swing. The Eclectic will have a run of only 200. This seems to be the first time that a car has used more than one renewable energy source at once: both wind and solar in the same car.

The ranges are still small, and the top speed of the Eclectic is only 31 mph, but I think all three cars have arrived as the first practical, production, renewable energy vehicles. Of course the top two models will cost a pretty penny (and have awesome performance to match), but that’s how it is with any new technology.

You can read more, and get all the specs at the Venturi website.

You can buy green power from the utility you already use. For a nominal fee (we pay four dollars a month) you pay your utility a little extra to buy electricity from a renewable source.

While the green power you buy does not go directly to your home, it does get fed into the electrical grid and helps pay for the costs of establishing, expanding, and maintaining the network of green power systems.

While the immediate feel good factor is relatively low because you cannot see the effects of your efforts, you are helping to subsidize a part of the power industry which will eventually be a major part of the effort to reduce our reliance on fossil fuels.

The link below is for Puget Sound Energy’s Green Power Program. Feel free to check it out. To see if you can purchase green power, contact your local utility.
