Comment Re:WOW! (Score 4, Informative) 88

If you actually watch the video, you will see the machine adds fibreglass rebar already automatically. Also you will see that the exterior walls are printed hollow so you can spray foam inside them afterwards (basically the same concept as ICF except it is 3D printed).

Yes, the framing, siding, and roofing is not the only part of building a house. Obviously you still have interior work to do after the fact. However, it is a very significant portion, and this machine can do all of them in 24 hours (have a bigger house? Use 2 or 3 machines to keep it at 24 hours...). When was the last time you saw a house framed, roofed, and sided in 24 hours? You can't even assemble a factory-built home on site that fast... I know cause I have one.

Comment Re:Uber + Autonomous vehicles = Dumb (Score 2) 151

"Uber getting involved in autonomous cars makes absolutely zero business sense"

Er... if this is truly your thinking, you'd make a very poor CEO.

Self driving technology will make companies like Uber completely obsolete unless they either get on the badnwagon, or find a partner - and there aren't many left. Tesla is already working on building their own autonomous ridesharing fleet to compete with Uber. Ford has also purchased a ridesharing company. BMW is starting their own. Lyft is partnered with GM.

This is all a giant race, and we don't know who will come out on top, but if Uber just sat around and did not invest in this area, they would most assuredly be out of business in under 10 years.

Comment Playing with fire (Score 3, Insightful) 170

Any frequent traveler like myself will tell you you're playing with fire leaving valuables like a laptop in a checked bag. Checked bags are lost ALL THE TIME, stolen from all the time, and damaged even more. If you're lucky, your travel insurance may throw you a bone for the value of the laptop but they won't be able to replace the value of what's on it. I won't even get into how disruptive it will be to your business trip or vacation to have a missing laptop.

Rule #1, avoid checking luggage at all costs. Rule #2, if you are forced to check, don't put anything in there except clothing, sundries, and other things of little value.

Comment Re:Only because of the Organians (Score 1) 116

Which companies do you propose we bust?

The last company people around here proposed be "busted" was Microsoft for it's bundling of IE... something which as we now know looking back has turned out to be mostly irrelevant.

A lot of people around here seem to want to "bust up" Google, but fail to provide any evidence of them actually using their position in any given market to influence their position in another unjustly. In fact, quite the opposite since they seem to go out of their way to list direct competitors prominently in their search results... Antitrust law does not allow the government to "bust up" a company just because they turn out to be wildly successful.

Comment Re:How much net energy used? (Score 1) 228

There is a huge difference in that Ethanol is mobile, pumping water uphill is not. You can't run a car or a truck or airplane or boat on water pumped up a hill*, but you can on ethanol.

* Unless you use that to charge batteries and then discharge in the vehicle, but by this point you are WAY below in efficiency, not to mention the cost of producing all of those battery vehicles. For the most part, cars and trucks and boats can burn ethanol with very little modification.
