I thought this was a proposal to give convicted criminals the choice between prison or school.
This is the camel's nose in the tent. If this is adopted, the threshold will move down and the percentage will move up and eventually will touch everyone.

Liberal politics turn everyplace into a disaster. CA was at a high bar so it is taking a little longer.

There is new data from the Juno Mission, that Jupiter has a diluted core.

"...heavy elements (elements other than hydrogen and helium) are distributed within a region extending to nearly half of Jupiter’s radius."

Re:New technique stores summer heat until it's needed in winter on Thursday January 12, 2017 @04:25PM (#13386248)
If the system scales based on the fluid, the $/kwh could get pretty low. Would be interesting what a MWh amount of heat storage would cost.

Past midnight, couldn't stop reading.

Can't imagine the sheer horror of their predicament in that terrain, during the summer heat.

The author deducing how the Germans ended up in that canyon was a stroke of investigative genius.

Lifetime cycles are an issue for Li-ion batteries.

For example, lets look at the Tesla Powerwall numbers. The Powerwall warranty covers 85% of capacity with 740 cycles in the first two years -- whichever comes first. Then it covers 66% capacity with 1,087 cycles in three years, and finally, it covers 54% of capacity for 2,368 cycles in five years. http://www.greentechmedia.com/articles/read/is-teslas-powerw...

Running the numbers for the Powerwall, 85%, 66%, and 54% of 7kWh is 5.4, 4.6, and 3.8kWh respectively.

(740cycles x 5.4kWh) + (1087cycles x 4.6kWh) + (2368cycles x 3.8kWh) = 17994.6kWh

Thus the cost per kWh stored is

$3000/17994.6kWh = 16.7 cents/kWh.

Not included is the shipping and installation cost, which could add another $300 - $500, which would run

$3300/17994.6kWh = 18.3 cent/kWh.

Anyone know how many transaction per second the Ethereum network can handle?

Also, how fast does the blockchain grow in size in GB/month?

Autonomous vehicles with inductive charging will solve this problem. Tell your car to charge then park itself, and have it come pick you up when you're ready. It's going to be awesome.

The treatment of Wegener's theory of Continental Drift is a lesson for the scientific community.

If one is not allowed to mention or entertain an idea without career repercussions, it harms the scientific process. Similarity to the treatment of climate change "deniers" comes to mind.

The merit for the cause of climate change should be based on evidence, not by keeping opposing views off the table by threatening the careers of those who want to explore research other ideas.

If you want to commit crimes with impunity, become a banker. Otherwise, you're just needed fodder for the corporate prison system.

Arnie Gunderson from Fairewinds makes the case that the explosion in fuel pool of Unit 3 at Fukushima was a detonation (faster than the speed of sound) and not a deflagration (speed of sound). A plausible reason was a initial hydrogen explosion in the pool distorted the fuel and initiated a moderated prompt criticality. http://www.fairewinds.org/gundersen-postulates-unit-3-explos...
