People interested in my web site may like to know that I have added a new page on Portugal for armchair travelers (or people who might be thinking of going there).

Portugal is a relatively recent discovery for my family, and it didn't take long to fall in love with the country and with its very friendly people. The cost of living is low, and the Portuguese really care about their environment, with almost 100% of their energy needs coming from renewables.

If you have never been to Portugal... then I highly recommend it!


If you're interested in environment issues, you may like to know that I have just updated the Environment & Technology section of my web site, which tries to provide useful information and links about a wide variety of environmental solutions and issues.

The issues now include, of course, an anti-science, anti-environment President of the USA. However, as you will discover if you visit my web site, there are still very positive things happening both in the USA and elsewhere.

Although the section is quite large, you will hopefully find that it is easy to navigate. I have tried to make it rich in high quality links (many of which have also been updated), so that what you see on the pages are just the tips of many interesting icebergs, so to speak.

If you visit it and really like it, then please share it anywhere you think it would help the environment - thank you!

I am sure that the section could be further improved. Any suggestions would be really welcome.

Cruise on the Douro River, Portugal (with a day trip to Salamanca in Spain), June 2016

We recently went on a 7-day cruise on the Douro River in Portugal, a wonderful experience. This cruise started and ended at Porto and included navigating 5 locks, among them the highest single-lift lock in Europe.

We saw many examples of Portugal's use of solar power and hydro-electric power, and learnt why its world-leading investment in renewable energy is so good for its economy, as well as for the environment.

We also visited the Art Nouveau and Art Deco Museum in Salamanca. Photography wasn't permitted there, but click the picture for my post about it.

If you're interested in environment issues, you may like to know that I have just updated the Environment & Technology section of my web site, which tries to provide useful information and links about a wide variety of environmental issues.

The updated parts include a new section on Solar Roadways and a major update to Hybrid and plug-in electric vehicles, as well as a really interesting development in the area of Biofuels.

Although the section is quite large, you will hopefully find that it is easy to navigate. I have tried to make it rich in high quality links (many of which have also been updated), so that what you see on the pages are just the tips of many interesting icebergs, so to speak.

Some time ago, Julie and Scott Brusaw grabbed the imagination of several million people, with an invention that may eventually benefit the lives of hundreds of times that number: a modular system of intelligent solar paving slabs made of non-slip, highly durable glass, with many applications.

Apart from generating electricity, these paving slabs can provide variable signage or illumination from high intensity LEDs, keep road surfaces free of snow or ice, and perform a variety of other useful functions.

These smart slabs will also act as local components of the Smart Grid.

From the page:

In a recent New York Times business trend piece, the small but growing movement to transform -- or at least disguise -- these ugly but crucial energy ducklings into aesthetically conforming swans is explored.

Most notable are SRS Solé Power Tiles from SRS Energy. The company is working with California's U.S. Tile to create tiles with embedded solar cells that mimic traditional tile roofing in Southern California and the Southeast. At a demo home in California (pictured below), a homeowner replaced terra cotta tiles on a portion of his roof -- about 300-square feet -- with Solé Tiles in about four hours. As a result, the homeowner's roof will generate about 2,400 kilowatt-hours of juice a year and his roof isn't festooned with bulky black squares that scream to neighbors and passersby, I have photovoltaics!


Whatever the commercial problems, the world will get to this one day. A great find from my friend Sandy.
