Google Invests $168 million in Largest Solar Tower Power Project

Google is investing in a new solar tower power project located in California that will generate 392 gross MW of clean, solar energy. That’s the equivalent of taking more than 90,000 cars off the road. Google has now invested $250 million in clean energy.

Investing in the world’s largest solar power tower plant

works by using a field of mirrors, called heliostats, to concentrate the sun’s rays onto a solar receiver on top of a tower. The solar receiver generates steam, which then spins a traditional turbine and generator to make electricity. Power towers are very efficient because all those mirrors focus a tremendous amount of solar energy onto a small area to produce steam at high pressure and temperature (up to 1000 degrees F).
…
Several large solar projects are in the works in the sunny Southwest (and around the globe), but Ivanpah will be the first solar power tower system of this scale. The Ivanpah Power Tower will be approximately 450 feet tall and will use 173,000 heliostats, each with two mirrors.

The Department of energy is also providing financing for this project. The project is 10 times larger than the largest solar photovoltaic project in California.

Appropriate Technology: Washing Clothes by Machine Instead by Hand

Hang Rosling provides great presentations exploring economics and human well being. I agree with his point that we should be thankful for economic and engineering progress that has freed us from menial tasks and allowed us to spend our time in higher value ways.

We need to remember (as he shows) there are many in the world that still do not enjoy these advances. For example, a majority of the world must hand wash their clothes. Engineers should continue to focus on the mass of humanity that needs fairly simple solutions.

He is also right that we need to find solutions to the extremely heavy use of fossil fuels by the rich countries. If the rich countries don’t reduce the pollution there will be great problems. And if the costs of clean energy are not decreased (which they should do) fast enough (which is the question), those that start to be able to afford the rich lifestyle, will add to the dangers we face economically and environmentally of continuing the unsustainable energy footprint the rich countries have been making.

Wave Disk Engine Could Increase Efficiency 5 Times

Norbert MÃ¼ller’s group has received $2.5 million from the U.S. Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) in 2010 to build and develop the wave disk engine, which uses turbo combustion “shock wave” technology to convert either liquid fuel or compressed natural gas or hydrogen into electrical power. With this engine, fuel efficiency for hybrid vehicles could increase 5 times compared to internal combustion engine vehicles on the road today (and 3.5 times less than current hybrid cars), while reducing costs by 30%. The goal of MÃ¼ller’s team is to produce an engine that would give hybrid vehicles a 500-mile driving range and reduce carbon dioxide emissions by as much as 90%.

In the video he says they hope to have the engines in production vehicles within 3 years. My guess is he is being quite optimistic, but we will see. The new engine would allow 1,000 pounds to be removed from the weight of cars (by removing the need for drive train, radiator…).

Backyard Wildlife – Chimpmunk

photo of a chipmunk

I have enjoyed seeing chipmunks run around my yard for several years, but getting a photo of them is not easy. They are quite fast and don’t sit around for long. Occasionally they will seem to bask in the sun while they are eating a seed but then they are always quite far away. This is the best image I have been able to get.

Chipmunks have an omnivorous diet consisting of grain, nuts, fruit, berries, birds’ eggs, small frogs, fungi, worms, insects and on occasions small mammals like young mice. At the beginning of autumn, many species of chipmunk begin to stockpile these goods in their burrows, for winter. Other species make multiple small caches of food. These two kinds of behavior are called larder hoarding and scatter hoarding. Larder hoarders usually live in their nests until spring. Cheek pouches allow chipmunks to carry multiple food items to their burrows for either storage or consumption.

$60 Million in Grants for Undergraduate Science Education

The Howard Hughes Medical Institute (HHMI) is challenging colleges and universities to think creatively about how they educate future scientists, science teachers, and a scientifically-literate public. The Institute has invited 215 undergraduate-focused colleges and universities from across the country to apply for a total of $60 million in science education grants. I am very happy that HHMI continues to help provide support for science education.

Sadly USA government leaders (local and national) have chosen to cut the importance they place on science education over the last few decades we have coasted on the gains we made in the 1960s and 1970s. That is no way to succeed. Thankfully a few foundations, with HHMI probably leading the way, and some great schools have kept the USA in a leadership position, but that leadership shrinks each year. And at the primary and secondary school level the USA dropped far back in the pack decades ago for science eduction The top countries in primary and secondary science education are now Finland, Hong Kong and Korea.

Since 1988, the Howard Hughes Medical Institute has awarded $820 million to 264 colleges and universities to support science education. Those grants have generally been awarded through two separate but complementary efforts, one aimed at undergraduate-focused institutions and the other at research universities. HHMI support has enabled more than 80,000 students nationwide to work in research labs and developed programs that have helped 95,000 K-12 teachers learn how to teach science more effectively.

The new grants will range from $800,000 to $1.6 million over four years for individual institutions and up to $4.8 million over four years for those applying jointly.

The biggest change in the new 2012 competition is the requirement that applicants focus on a single educational goal that unites their proposed science education program. In the past, HHMI’s grants have allowed applicants to submit projects in four categories: student research, faculty development, curriculum and laboratory development, and outreach. Although schools were not expected to put forward a program in every category, Asai notes the modular design of the grant competition often led schools to “check the boxes” rather than encouraging them to think strategically about how these activities can help them reach an overarching science education objective.

Hardware Hacker Challenge Invitation

Calling all Inventors, Makers and Hackers. This is a fun idea for a hacker invitation. Teams decode the invitation embedded in hardware to reveal their password for an invitation to the creation event.

Google Art Project – View Art from the Hermitage, the Met…

Google Art Project lets you view art from the Hermitage, Van Gogh Museum, the Met, Tate Britain, National Gallery and more museums around the world. The site lets you navigate the museum (similar to Google street view) and zoom in for very close looks at the the works of art.

The image above is a close up view of the Birth of Venus by Sandro Botticelli. In the lower right of the image you can see the portion of the painting that this view is zoomed into.

You can create your own artwork collects, which is a cute feature. Unfortunately it is tied to the still incredibly broken Google ideas on social Internet applications. I find it amazing that a company that does so many things so well, can have such continuously bad ideas about social applications.

Cat Allergy Vaccine Created

McMaster University researchers have developed aÂ vaccine which successfully treats people with anÂ allergy to cats. Traditionally, frequent allergy shots have been considered the most effective way to bring relief — other than getting rid of the family pet — for the 8 to 10% of the population allergic to cats.

Both options, may now be avoided thanks to the work of immunologistÂ Mark LarchÃ©, professor at theÂ Michael G. DeGroote School of Medicine andÂ Canada Research Chair in Allergy & Immune Tolerance.

Building on research he’s conducted for the past 10 years in Canada and Britain, LarchÃ© and his research team have developed a vaccine which is effective and safe with almost no side effects. The research is published in a the January 2011 issue of theÂ Journal of Allergy & Clinical Immunology, a leading journal in the allergy field.

The researchers took one protein (molecule) that cats secrete on their fur which causes the majority of allergic problems. Using blood samples from 100 patient volunteers allergic to cats, they deconstructed the molecule and identified short regions within the protein which activate T-cells (helper cells that fight infection) in the immune system.

Using the amino acid code for the whole protein, researchers made synthetic versions of these regions. For the cat allergy vaccine, they found seven peptides (strings of amino acids). “And those synthetic peptides are what we mix together to make the vaccine,” said LarchÃ©. “We picked the peptides that would work in as much of the population as possible.”

Known as “peptide immunotherapy,” a low dose of the vaccine is given into the skin. Initially, four to eight doses a year may be required, but the side effects of the traditional allergy shots do not arise, LarchÃ© said. The optimal dose will be determined in phase three clinical trials which are getting underway with a much larger group of cat allergy sufferers.

The development of a vaccine to treat people allergic to cats is the first in a line of vaccines developed withÂ Adiga Life Sciences, a company established at McMaster in 2008. It is a joint venture between McMaster University Circassia Ltd., a UK-based biotech company.

Adiga and McMaster are now collaborating on research into the use of peptide immunotherapy for house dust mite, ragweed, grass, birch tree and moulds

Votizen is Looking for Software Engineers

Link broken by pointy haired boss at Votizen, so I removed it. This phb behavior will make those of us who link to websites hesitant to trust anything Votizen posts will stay around 🙁

A nice presentation on why software engineers should work at Votizen.

Google Summer of Code is Accepting Application Now

Google Summer of Code 2011 is accepting applications. This is a great initiative I have highlighted previously: Google Summer of Code 2009, Google Summer of Code 2008. The deadline for applications is April 8th.

Google Summer of Code is a program that offers student developers stipends to write code for various open source projects. The program has brought together over 4,500 students with over 300 open source projects, to create millions of lines of code. Participants (including students and mentors) have represented over 85 countries. The program, which kicked off in 2005, is now in its seventh year.

Participating organizations include: R Project for Statistical Computing, Debian Project, WordPress and the Marine Biological Laboratory. (9 of the 175 participating organizations list Ruby as part of their project :-).

For 2010 the effort had a budget of $5,000,000 and accepted 1026 students partnering with 150 Open Source organizations. This year they plan on 1,150 – 1,200 student positions. For 2007 they had 6,200 applications and 7,000 in 2008. I don’t see any data on applicants for 2009.

As for the application it should include the following: your project proposal, why you’d like to execute on this particular project, and the reason you’re the best individual to do so. Your proposal should also include details of your academic, industry, and/or open source development experience, and other details as you see fit. An explanation of your development methodology is a good idea, as well.
