Swimming Pools

A good friend of mine is always saying to me that he wishes they made an all-in-one alternative energy kit. His Acme alternative energy kit would consist of a large water tank painted black to act as a thermal mass, solar water heaters, solar panels, and a wind turbine.

I’ve been thinking about this model and realized that many people already have this system partially installed. Partially installed because many people have a swimming pool.

A swimming pool could be used as a solar mass collecting heat from the sun and stirring it for those cold winter nights. The pool would work really well with a heat pump and a radiant floor heating system. Most people just cover up their pool with an insulating cover anyways, why not make that an extra thick and rigid cover capable of supporting solar water heaters that would circulate hot water into the pool.

With a solar hot water photovoltaic hybrid system on your pool, you now have hot water, a warm house, and electricity. if you were to add a wind turbine, you would have your Acme alternative energy kit!

Lastly, in the summer time you could use your swimming pool and your water heaters in reverse to radiate heat out of the pool. With a swimming pool full of cold water you’ll enjoy a cool home all day. You would be able use your home to heat your pool for a mid day swim.

Japan’s First Solar Power Cargo Ship: Green-wash

In response to the article about a company that built a solar cargo ship that only derives 0.02 percent of its propulsion energy consumption from solar:

I couldn’t agree more. That’s green-washing alright. They would have been better off throwing those solar panels up on a roof top some where. I’ve been saying for a while that we need to consider energy density in our consumption. It’s easy to make electric cars because they require low energy density. However, you must have high energy dense fuels to maintain shipping and air travel. Electric airplanes just aren’t realistic with current battery weight. We should be conserving fossil fuels for airlines and shipping while also drastically cutting residential lighting, heating, and transportation fossil fuel consumption. I say, put a $0.50 / gallon tax on gas under $3.50 a gallon to curb consumption and raise money for infrastructure.

Sustainability Exchange

Dear Readers,

Just thought I would let you all know about a new interest in my life.

Some friends from USM and I are organizing a new group called Sustainability Exchange.

The purpose of the group is to swap ideas, articles, news, and videos around sustainability. We’re hoping to start a podcast soon and one day we hope to give workshops.

Currently, we’re organized only as a facebook group but there are plans to synergize with an up and coming non-profit to help accomplish some mutual goals together.

I will keep you posted, but if you’re interested, join the facebook group because I’ve posted a ton of links.

Together Green Fellowship

I’m contacting you today on behalf of Audubon to inform you of the TogetherGreen Fellowships that have recently been awarded to forty of the nation’s most promising conservationists, two being from Portland, Oregon! TogetherGreen wants you and your readers to meet these Fellows who will create a positive environmental change in your community. Two Portland, Oregon advocates are the proud recipients of a new national fellowship designed to advance the work of individuals with outstanding potential to help shape a brighter environmental future. Marcelo Bonta and Tony DeFalco are two of only 40 people selected from competitors nationwide for the TogetherGreen Conservation Leadership Program, part of a new conservation initiative of the National Audubon Society with support from Toyota.
