Last I checked the biggest cost in the electric bill is transmission, by a wide margin. Home generated power however small helps everyone.

U.S. homes typically get power through two hot wires. The hot wires are connected to a utility company's transformer and are 180 degree out of phase. Each supplies 120 volts.

The power from the plug-in outlet is consumed by any devices connected on the same circuit first. Any extra flow through the electric panel’s bar connecting the circuits on the same 120V phase, where the devices on them use the extra next. Any excessive power flows back out of the meter on the 120V phase line on your service connection to the transformer at the street block. The transformer might feed it to your neighbors. In any case the transformer feed electricity to the other 120V phase line back into your service connection, the meter, the panel, the other split phase bar, the circuits on it, and the outlets on them. The devices on the other split phase circuits technically are not using the plug-in power directly.

Most modern meters measure electricity going in and out on both split phase lines as a whole, as a net amount, so the electricity consumed in the other split phase circuits is offset by the plug-in power. However some old meters add the outgoing electricity up as consumption so you are paying for the electricity fed into the grid. Call your utility company to make sure.

Also, unless you have a net metering agreement with your utility company, you won’t get paid for any excessive electricity fed back into the grid.


They are selling you a rack of computers instead of a single computer, with well integrated high speed connection, storage, power, and cooling.

Driving is a privilege. Gun ownership is a right.

> Gun ownership is a right.

Tell that to felons. Or people with diagnosed mental health issues of certain types.

The idea of a "right" is hilarious. Whenever you have an entity (like a government) that has the power of force or imprisonment over you, everything is a privilege.

I can't think of very many "rights" that haven't been abridged, curtailed, or violated by governments in ways that have been held to be legal when reviewed by courts.


A right doesn’t mean it’s absolute.

gun ownership can't be a right, as it can be taken away from any usamerican

That’s why you need to fight for it.

A guy I knew back in college (in the same computer club) work on the IceCube project in Lawrence Berkeley Lab. Hello, Art Jones!

Since neutrinos don’t interact with much of anything, its path doesn’t deviate from its origin. Different origins emit neutrinos with different levels of energy. When a neutrino hits a nucleus, the blue light emitting particle in ice follows closely the same direction. Measuring the direction and the magnitude (lighting energy) of the vector we can classify its origin. Collecting a bunch of the same signature we know there's an object at that direction emitting at that energy level. From the vector and energy we kind of know whether it’s from the solar system or not.

Identifying the origin let us see objects behind dust clouds or other obstacles.

How does this not violate conservation of momentum? Are you saying every single collision is head-on?


Most paths of the high energy observable collisions follow a very close alignment to the original neutrino's path. The forward momentum of a high energy neutrino completely dominates the collision. Imagine an one-ton ball hitting a billiard ball. Doesn't matter what direction the billiard ball was going; the resulting path is the one-ton ball's path.

In other cases, the particle being collided is scattered and won't show up in the detector. Low energy neutrino collisions also have very faint light and difficult to detect. Solar system produced neutrinos are in this category.


DER (distributed energy resources) is getting popular. This program is like a UPS for the house.

Are there still cheap Chrome box that can be rooted to install other Linux?


Yep, I bought Apple at $19 after Steve Jobs went back to Apple. Sold them at $80.


People seem to miss the point of the project. It’s not emailing you on failure. It’s emailing on missing reports of scheduled runs. If you rely on the job to report failure, the machine could go down. In that case you won’t get any email on the failed run.
