Comment: I'm not an EE, but are new electrodes good enough? (Score 1) 260

If you could get a mechanical inverter to work for a max of 100 hrs using new electrode technologies... you should be able to make it small enough.I'm talking spin switched.

In short, My question is, electrodes are getting extremely good maximizing conduction and minimizing wear, but are they good enough to make mechanical switching a possibility?

Say funnel a MAX of say 20 amps @ 12vDC to a spin a high efficiency brushless DC motor nice and fast. The DC motor would be attached to a plate that would have a Rotating I (maybe an X?) of High tech carbon nanotube ended graphene electrodes spining in a circle. Spinning at the right frequency, it should convert the DC to square AC. Round it out, and then a computerized Vmeter + tied back to an ESC could regulate the motor's speed keeping the phase locked good n tight, minimizing fluctuations.

I'm not an EE though, I feel like there's something wrong w/ this, that the loss might be too high, or maybe that kind of electrode technology isn't there yet?
Just curious..

While most of your points are legit, I think we need to start making a distinction, you apply the Rules in two different ways against the "model aircraft" please stop calling these things drones.

Is a quad, hex, or octo copter a helicopter? is a model helicopter a helicopter? back in the day unmanned aircraft were still fixed wing, it wasn't until controllers became inexpensive that the idea of quads started to come to light.

FAA is already trying to impose some pretty severe restrictions against modelers.

European Court of Justice Strikes Down Data Retention Law 77

New submitter nachtkap (951646) writes with some good news, as reported by the BBC: "The EU's top court has declared 'invalid' an EU law requiring telecoms firms to store citizens' communications data for up to two years. The EU Data Retention Directive was adopted in 2006. The European Court of Justice says it violates two basic rights — respect for private life, and protection of personal data. Germany's supreme court did call on the ECJ to look into this issue as well."
