A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson).   It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur.   Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American , Time , and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” ( Booklist ).   “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” — Publishers Weekly J. RICHARD GOTT III is a professor of astrophysical sciences at Princeton University. For fourteen years he served as the chairman of the judges of the National Westinghouse and Intel Science Talent Search, the premier science competition for high school students. The recipient of the President’s Award for Distinguished Teaching, Gott has written on time travel for Time and on other topics for Scientific American , New Scientist , and American Scientist .

India and U.S. team up to give boost to solar power startups

India and U.S. team up to give boost to solar power startups

By on Jun 8, 2016Share

Indian Prime Minister Narendra Modi is serious about fighting climate change, and about collaborating with the U.S. to do it, he made clear during an address to the U.S. Congress on Wednesday. He said that “protection of the environment … is central to our shared vision of a just world,” and called for “a lighter carbon footprint and a greater use of renewables.”

On Tuesday, the first day of Modi’s state visit to Washington, D.C., his government and the Obama administration issued a joint statement on U.S.-India cooperation that led with plans for expanding clean energy deployment in India. The most important component is $60 million in clean energy financing. The Indian and U.S. governments will split the costs of helping small Indian solar startups get off the ground, especially in rural villages that are not on the country’s electrical grid. These subsidies and loan guarantees should help the young companies expand to the point where they can attract far greater international investment — as much as $1.4 billion, the two governments estimate. That additional money will mostly come from the private sector, although some may come from other government sources, such as the U.S. Export-Import bank.

“These off-the-grid companies are small and need funding to scale up,” John Coequyt, the Sierra Club’s director of international climate campaigns, told Grist. “The hope is that it will raise far more than that seed money.”

Boosting India’s renewable sector will help curb the need for expanded coal power by providing electricity to areas in India that current lack it. Modi has emphasized in past speeches that 300 million Indians still don’t have access to electricity. As seriously as India takes climate change, Modi warns, it won’t keep its people in the literal dark. The new financing deal with the U.S. is specifically designed to address that concern.

The two countries also made plans for a $30 million public-private research program on smart grids and storage of renewable energy, and agreed to improve cooperation on wildlife conservation and combating wildlife trafficking.

One part of the announcement that won’t sit well with some environmental activists is that India will buy six nuclear reactors built by Westinghouse, an American firm. But even green groups that oppose the nuclear portion of the deal are pleased overall. Sierra Club Executive Director Michael Brune said in a statement that the agreement will “accelerate the momentum toward a 100 percent clean energy economy” and “help connect families to clean, reliable electricity after generations of being failed by the fossil fuel grid.”

India is the second most populous country in the world, and its enthusiastic participation is crucial to any global effort to limit climate change. It has poverty that needs to be alleviated through economic development and it has large reserves of coal — a potentially lethal combination for the planet.

Before the U.N. climate negotiations in Paris last December, climate hawks were nervous about whether India would cooperate. Efforts to bring the country into a strong deal proved challenging but ultimately successful. India agreed to dramatically increase its renewable energy deployment and to increase its coal use less than previously expected (although still not enough to help the world stay below 2 degrees C of warming).

This represents major progress. In 2014, Modi skipped the U.N. Climate Summit in New York and made peculiar, inscrutable comments to the U.N. General Assembly shortly thereafter suggesting that yoga could help combat climate change. But, as pollution from burning coal and gasoline has turned Delhi and other Indian cities into some of the most polluted in the world, India has started to shift its stances.

This week in D.C., Modi reiterated his commitment to the Paris Agreement, pledging to work on getting his government to ratify it this year, a complex and arduous process. The global community is newly focused on bringing the agreement into effect before next January because Donald Trump has threatened to try to undo the global pact. If at least 55 countries representing at least 55 percent of global emissions have ratified it before a President Trump takes office, then the agreement will go into force and can’t be easily unraveled.

India’s new plans for collaborating with the U.S. won’t just matter in Delhi and D.C. India is the de facto leader of a large bloc of developing nations in climate negotiations, so its latest actions will reverberate around the world.
