Comment Could calculate based on fast rail (Score 1) 465

You'll probably get most of the value out of electronics exports from China to the US that currently go by sea when air transport would be too expensive. How much is that worth and how much more would it be worth if you could get it to consumers how much faster?

If you can get a 10% increase in price because you have all of China's exports on store shelves a month earlier it could be big bucks. Unlikely to pay off a trillion dollars but anyway.

Comment Happens all the time (Score 3, Interesting) 132

There's news like this every week. None of these is clearly better cheaper or faster to market than any other breakthrough like it at this early stage. It all evens out to a fairly steady improvement over time. Battery weight and prices still keep halving every five years or so and that's already factored into stock prices, minus some risk.

Comment They already sell batteries for power companies (Score 1) 116

From TFA:

The company created a subsidiary called ACCUmotive in 2009 to develop lithium-ion batteries. It built an energy-storage array that is now operated by German electricity joint venture Coulomb. The system's 96 lithium-ion "modules" boast a combined 500 kilowatt hours of storage capacity, which is used to stabilize the Saxony Kamenz power grid. There are plans to expand this installation to 3,000 kWh of storage capacity.

Comment Tesla battery also far larger than needed (Score 1) 334

The Tesla Battery's cost $13,000 would pay most people's electric bills outright over it's life.

The Tesla's battery is also 53, 70 or 85 kWh whereas the average household uses around 1 kW (kWh/h) and certainly can get by with a few kWh of storage to handle its overproduction of solar during a day.

In the end, it's just economics. Does solar + battery pay itself back in lowered electricity bills? If it does, nothing else matters.

Statistics means never having to say you're certain.
