Who Killed the Electric Car?

Who Killed the Electric Car?  by Alice Friedemann August 29, 2014 The battery did it.  Batteries are far too expensive for the average consumer, $600-1700 per kwh (Service). And they aren’t likely to get better any time soon. “The … Continue reading

Revolutionary understanding of phsics needed to improve batteries – don’t hold your breath

What this Department of Energy document shows is that we can’t make the necessary REVOLUTIONARY breakthroughs to electrify cars until we understand the physics of batteries, and points out that “battery technology has not changed substantially in nearly 200 years.” … Continue reading

Electric Grid Energy Storage

Storing electricity Electricity can’t be stored. It has to be converted to something else.   Nearly all of the electric grid storage (95%) comes from pumping water up to a reservoir so the water can fall again and generate electricity. But … Continue reading

Batteries are made of rare, declining, and imported minerals

Batteries use many rare, declining, single-source country, and expensive metals.  They consume more energy over their life cycle, from extraction to discharging stored energy, than they deliver.  Batteries are an energy sink with negative EROI, which makes wind, solar, and … Continue reading

Renewable Energy can’t supply more than 30% of electricity without revolutionary battery breakthrough

Wind and solar are too intermittent to comprise much of electric grid power now, according to Steven Chu, former US energy secretary.  In 2010, Chu said, “Without technological breakthroughs in efficient, large-scale energy storage, it will be difficult to rely … Continue reading

Why aren’t there Battery Powered Airplanes?

  A 200-seat airplane weighs about 115 tons at take off. About a third, or 38 tons of that weight is the kerosene fuel. The other 77 tons are the passengers, their luggage, and the airplane itself. An electric, battery-powered … Continue reading

Who killed the Electric Car? The Battery Did It.

Despite billions of dollars spent on battery since the first battery was created in 1800, there is still no battery in sight that could power cars because batteries depend on electro-chemical processes, resulting in little power density and short life … Continue reading
