What I really look forward with BECs (although simple atomic interferometers based on ultracold atoms would do, too) is super-sensitive magnetic field detection.

One can detect magnetic fields from a shielded laptop, even many meters away, and figure out what's happening inside (e.g. leaking secrets etc).

I think, not a terribly difficult experiment, but nobody has performed it: need ultracool physicists and hackers in one lab room

Sorry, but this looks like a completely uneducated opinion.

There were many attempts to create virtual money which cannot be shit down, and all of them dated before Bitcoin failed due to government intervention. Bitcoin solved that, and the simplest solution was the wasteful proof of work.

Of course, when someone is using the same principle for something centrally controlled, which can be done by a database, that is a different story.

Well, this doesn't look right to me. Imagine that the moon is actually a filter at the path of the sunlight.

Sun's temperature is 6000 K. Moon's surface is pretty black: it reflects only 12% of the light.

So, effective temperature of the Sun reflected by Moon, considering that thermal radiation is proportional to T^4, is 6000 * .12 ^ (1/4) ~= 3500 K. That's quite enough to light up some fire! Of course, the spectral composition of the light will be not thermal etc, but the estimate should be close enough.

Why doesn't the Moon itself heat up like that? Well, the rocks on Earth don't heat up to 6000 K either... I think, it's partly that they are "not surrounded by sun", partly that the Moon is a giant cold heatsink

Meanwhile, Elon Musk acquired more than 50% of the space launch market (while 5 years ago it was Russia who owned it).

Don't troll, buidl!

Reg A+ is indeed easier than an IPO. I've seen some companies doing that, and it's 1 year pushback, to say at least.

One year is an insanely long time these days!

You're not correct. I think, less than 50% of ICOs are not securities. But the way to prove is exactly this: ask a lawyer

All right, but if the coin is inseparable part of the resource, it cannot be a security. There is a thin line here.

Imagine a coin securitizing Bitcoin miners ("cloud mining coin"). Yes, that's a security.

Now imagine Ethereum. It was ICO'd, talking in today's terms. Is it a security? (hint: SEC just admitted it's not)

There are two things here:

* It's not OK to raise 200M with no team and product;

* Compliance only creates obstructions, not protection.

What's even more surprising is the position of Coinbase:

"Given how useful it is for criminals to have financial accounts that are seemingly unconnected to them, I view this feature of the legislation as an important next step in the fight against global money laundering."
