Using waste heat from automobile exhaust

http://www.ct.gov

 With the completion of a successful prototype, engineers have made a major step toward addressing one of the leading problems in energy use around the world today -- the waste of half or more of the energy produced by cars, factories and power plants. New technology is being developed to capture and use the low-to-medium grade waste heat that's now going out the exhaust pipe of millions of automobiles, diesel generators, or being wasted by factories and electrical utilities.

Need to Relax and Explore?

Stressed about the bad economy? Sick of trudging over ice and through biting winds? You need a vacation!

Yes, staycations are cheap and inherently green (since we don't normally consume much when we stick around our neighborhoods). But we also enjoy daydreaming about fantasy adventures. If you are still flush, wow your valentine with the experience of a lifetime. If you're like the rest of us, at least you can hope, and maybe plan, together.

How to save money, and protect the environment, when you're on vacation.

By Jeff Yeager

Think Locally, Travel Globally

I'm a big believer in the popular environmental mantra: "Think Globally, Act Locally." When it comes to saving the planet, that saying is as true as it is simple.

And when I travel, my rule of thumb for keeping it green and keeping it cheap is: "Think Locally, Travel Globally." You'll usually find the most eco-friendly and genuine travel experiences when you spend less — not more — and get local, no matter where in the world you're wandering. It's all about traveling independently (not in a tour group or packaged tour) and drilling down to the local level, getting a true sense of place by experiencing it as if you live there.

Here's how:

Guidebooks Kill

Consult a good, locally researched guidebook like those in the Lonely Planet series for basic background and logistical info before you travel, but don't use it to plan your every move, like where you'll stay, eat and hang out. By the time a guidebook recommends something, it's usually overrun with tourists (and overpriced).

Travel Without Reservations

Except for perhaps the first night or two when you're traveling overseas and going to be suffering from jetlag, avoid making advance reservations at hotels and other accommodations before you leave home. You'll generally pay a lot more for lodging reserved from overseas, and they're rarely the type of local, affordable places you can only find once you're there. Plus, advance reservations limit your ability to be spontaneous in your travels.

The "Three L's Rule" (Look for Lines of Locals)

If you're looking for a good meal or friendly place to have a beer, put away your guidebook and open up your eyes and ears. Looking for where the locals hang out and chatting it up with them is the best — and cheapest — way to travel.

Local Transportation and Short Distances Are Best

To travel slowly, covering short distances, and staying places longer is the key to really getting a sense of place and people. Linger in places you've never heard of and where you don't see another tourist; don't plan an itinerary that's just one popular tourist destination (AKA "trap") followed by another. Taking public transportation, hiking or bicycling will give you a great opportunity to meet local people and see how they live. Plus it will save you a busload of traveler's checks.

Cheap Sleep

Americans can travel to almost anywhere in the world and pay top dollar to stay in an American-style hotel, just like the ones back home. Why even bother to travel if that's what you want? Look for locally owned, "mom and pop" places to stay, pensions and public camping facilities (sometimes free). Check out youth hostels, couch surfing and house swapping for a highly affordable, and rewarding, travel experience.

Prepare at Least Some of Your Own Meals

Sampling the fare in local restaurants is one of the joys of travel, but you'll sell your trip short — and spend a lot more — if you don't at least occasionally pick up some groceries from a local market and prepare some of your own meals. Maybe it's just simple breakfast foods or picnic supplies. Shopping for food where the locals shop is one of the most enlightening cultural experiences I know of when you travel, and it just happens to make travel much more affordable.

Keeping It Green When You Travel

Not surprisingly to this Green Cheapskate, a recent study commissioned by eco-friendly lodging chain Element Hotels found that 41% of the people they surveyed said that their vigilance about conserving resources is "due to the economy" (i.e. "It saves me money!"), while just 28% said it was "due to the environment." The upshot is that when people travel, their eco-conscious habits often slip; they're not as vigilant about things like turning off the lights in their hotel room, since they're not paying the electric bill. Don't leave your eco-ethics at home when you hit the road this summer, because you can't fool Mother Nature.

Custom-built prefabricated homes, such as the modernist perrinepod, encourage the green value that houses should be nothing more or less than their inhabitants need. By using less space and materials, prefab homes preserve natural resources, while leaving the smallest of footprints. They are usually manufactured in a way that leaves a smaller ecological footprint than conventional on-site construction.

17 Creative Things to Do with Phone Books

Is it just my imagination, or are they sending out updated editions of the phone book and Yellow Pages a lot more often than they used to? When I was growing up, it seemed like we had the same phone book the whole time. I remember it, because my Uncle George — who fancied himself the Human Hulk — said he knew a trick whereby he could tear an entire phone book in half with his bare hands. It didn't quite work out that way, although he did thoroughly mangle the A-G listings.

Laporan menunjukkan bahwa Cina  telah meningkatkan target di Tahun 2015 untuk penggunaan tenaga surya fotovoltaik (PV) menjadi 10 gigawatt (GW).  Ini berarti peningkatan target menjadi 2 kali, apabila merujuk pada Target semula pada  Rencana Pembangunan Lima Tahun (REPELITA) Tahap ke 12 (Development Plan for Renewable Energy during the 12th Five-Year Perio) yang sebesar 5 GW. Dokumen dan usulan ini telah disampaikan kepada DPR ( State Council) pada bulan Juni awal.

China’s New Solar Goal: Does a Doubled Target Mean Double Trouble?

http://www.asianoffbeat.com

Reports indicate that China is about to raise its 2015 goal for solar photovoltaic (PV) power to 10 gigawatts (GW), confirming an anonymous report that was leaked earlier this year. The target was originally set at 5 GW in the 12th Five-Year Plan released in March but has since been doubled in the newly submitted Development Plan for Renewable Energy during the 12th Five-Year Period, a document submitted to the State Council at the beginning of this month.
