Comment Re:Biofuels = Faster breakdown of engine parts (Score 1) 159

Go ask any mechanic who deals with vehicles that run on Biofuels such as BioDiesel, Green diesel, Bioethanol or >10% blends and you will find that they often clog up the injectors so badly that they need to be replaced (injector) 45% more frequently

Uh what? Biodiesel and green diesel remove varnish left behind by petrodiesel. Ethanol sucks because it attracts water and because you get poor output when you run it through an engine which also expects to run on gasoline. Running veg oil will certainly clog things up, though, or waste motor oil.

In any case, the cure for deposits from running one or the other kind of diesel (petro or bio) is to occasionally run a tank of the other. Problem solved.

Biofuels are about government subsidies and nothing more.

That is bullshit. Biodiesel or green diesel from waste fats are pure benefit, as are biofuels from algae. Unfortunately, the best of them (Butanol) is being suppressed by BP and DuPont until such a time as they can control it completely. If that's never, so be it, to them.

Comment Re:Switch Grass (Score 1) 159

Anyone who knows anything about Ethanol knows that the two best sources are sugar cane and switch grass.

'Best' how? Both of those are still soil-based crops. Algae is better because you can grow it on dirty water in most weather conditions above freezing, and it takes less processing than basically any other bio feedstock but shit.

This drives me crazy when people don't include the costs of labor.

That's intentional, because the design was given away. This is the future, and it's why 3d printing has corporations pissing themselves. If someone will give away a design for a product better than what they're selling, what chance do they have to continue to exist? Answer, none, and it's about damned time. Of course, this raises some serious questions about how we're going to distribute wealth when we don't need a bunch of slaves to stamp out widgets, and therefore we don't need slave-owners to crack whips over them. Instead of giving the wealth to the slave-owners, we might have to share it.

It costs about five to ten bucks more to get traffic with an old-school GPS, too — if you buy last year's refurb instead of this year's model. Get one with lifetime maps and you lose nothing, sometimes it's literally a styling change.

Where I live, cellular coverage is spotty. Traffic doesn't work there, but then online GPS doesn't work there at all.

That's good to know. I imagine one has to get used to a different set of torque values for fastening to aluminum as well.

One does indeed. Naturally they are all spelled out. All the hardware used on the car is "passivated" so you have to replace with like, or in some locations you can get away with stainless.

Comment Re:Personal Traffic Jam Drones (Score 2) 49

I have always thought a small car-mounted drone could be incredibly useful. Even if it could not be used above say 10MPH, just something that could pop up a few hundred feet in the air to give you a quick overview would be awesome.

Especially for finding parking.

Comment You already have a scouting drone for driving (Score 3, Informative) 49

I wish my car had a drone for instant scouting of traffic-jam alternates.

You do, it's called the Waze user that is ten minutes ahead of you down the road, mixed with many road sensors reporting traffic flow rates.

If you are using navigation many mapping applications automatically route around traffic issues (including Waze). I personally just have it up while driving, not really using navigation but just to keep an eye on traffic rates and issues. I've turned off many a highway before to avoid a Waze reported issue and taken a pretty obvious alternate route you could see at a glance on the map.

For anyone that has not tried leaving modern mapping applications open with traffic status enabled, I highly recommend it - just get a decent car mount so it's easy to see the display. I recommend Waze in particular only because it's one of the best at taking in user reports as to police or road hazards (like chair in right lane! just one example of something I have reported in the past).

Comment It is possible to know (Score 1) 288

It's probably impossible to know until you are actually in the same situation.

It's possible to know because you know how it is from the side of people noticing things. I find artificial hands immediately obvious, as much so as a robotic hand would be.

I think either would fare just as well in terms of not attracting notice when covered by a glove. Why not, then you would just look a little odd in summer...

$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand 288

An anonymous reader writes "A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' an open source hand which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."
