In my first book on Electric Cars, I covered those which were available in the US. In my new book, I decided to cover the world. I also venture into Electric Planes and EVTOLS - Electric Vertical Takeoff and Landing machines. Even though EVs are very interesting, you might get bored after the 100th or so. To relieve your boredom, I inserted stories about my visits from a couple of outer space aliens who are very interested in Electric Cars. Who says you can't mix research books with sci-fi and humor? I start with the most popular EVs. I cover many parts of the globe. And I cover lesser known Electric cars. Some places around the world don't have good roads or the roads are too crowded. There, electric motorcycles, rickshaws, and other vehicles are more popular than electric cars. And did you know that there's an electric skateboard? Electric Cars come in several models - Sedans, SUVs, Crossovers, Hatchbacks, etc. There are even little electric bubble cars. And there's a Amphibious E-Tricycle Camper. Now is a good time to get into an EV - there's availability. You'll get good range. And you'll save money on gas and maintenance. Besides, bans on ICE vehicles (internal combustion engine - petrol powered cars) are coming. Maybe not tomorrow, but soon. And supermost of all, owning an EV is cool and the wave of the future. And you want to get into the action now because you want to ride the crest of the wave. Some people are still worried about - what happens if the battery dies. I cover that. Good news - not a problem. I also cover converting your car to an EV (or rather hiring someone to do that for you) and EV Rentals. I conclude the book with what it would take to own an EV Dealership, My EV choices, and statements by World Leaders on EVs. I evaluate the more popular cars and provide a blank evaluation form so you can make your own evaluations. This book is packed with information, but I keep it light so you won't get bored. Actually, that's not true. I kept it light so that I wouldn't get bored.

DOWNLOAD EBOOK

A radically new understanding of and practical approach to climate change by noted environmentalist Paul Hawken, creator of the New York Times bestseller Drawdown Regeneration offers a visionary new approach to climate change, one that weaves justice, climate, biodiversity, equity, and human dignity into a seamless tapestry of action, policy, and transformation that can end the climate crisis in one generation. It is the first book to describe and define the burgeoning regeneration movement spreading rapidly throughout the world. Regeneration describes how an inclusive movement can engage the majority of humanity to save the world from the threat of global warming, with climate solutions that directly serve our children, the poor, and the excluded. This means we must address current human needs, not future existential threats, real as they are, with initiatives that include but go well beyond solar, electric vehicles, and tree planting to include such solutions as the fifteen-minute city, bioregions, azolla fern, food localization, fire ecology, decommodification, forests as farms, and the number one solution for the world: electrifying everything. Paul Hawken and the nonprofit Regeneration Organization are launching a series of initiatives to accompany the book, including a streaming video series, curriculum, podcasts, teaching videos, and climate action software. Regeneration is the inspiring and necessary guide to inform the rapidly spreading climate movement.

One hundred years ago electric cars were the most popular automobiles in the world. In the late nineteenth century and at the start of the twentieth century, they outsold every other type of car. And yet, within a couple of decades of the start of the twentieth century, the electric car had vanished. Thousands of battery-powered cars disappeared from the streets, replaced by the internal combustion engine, and their place in the history of the automobile was quietly erased. A century later, electric cars are making a comeback. Fears over pollution and global warming have forced manufacturers to reconsider the electric concept. A History of Electric Cars presents for the first time the full story of electric cars and their hybrid cousins. It examines how and why electric cars failed the first time - and why today's car manufacterers must learn the lessons of the past if they are to avoid repeating previous mistakes all over again. The book examines in detail: Early vehicles such as the Lohner-Porsche petrol-electric hybrid of 1901; Key figures in the history of the electric car development such as Henry Ford; Sir Clive Sinclair's plans to build a number of electric vehicles, designed to sit alongside the Sinclair C5; The return of the electric technology to vehicles as diverse as the NASA Lunar Rover, commuting vehicles and supercars; Future developments in electric cars. For the first time the full story of electric cars and their hybrids are examined.The hidden past of the electric automobile is uncovered and its future developments are discussed. Superbly illustrated with 300 colour photographs, many of which are rare and original sketch designs. Nigel Burton has written and lectured on cars and automotive history for more than twenty years.

Why has punditry lately overtaken news? Why do lies seem to linger so long in the cultural subconscious even after they’ve been thoroughly discredited? And why, when more people than ever before are documenting the truth with laptops and digital cameras, does fact-free spin and propaganda seem to work so well? True Enough explores leading controversies of national politics, foreign affairs, science, and business, explaining how Americans have begun to organize themselves into echo chambers that harbor diametrically different facts—not merely opinions—from those of the larger culture.
