Comment Re:Taking CO2 out?? (Score 1) 315

Diesel is close enough in chemistry to Kerosene/JP-1 that these should work:

It was good enough for Apollo 8 on the Saturn V.

As of 2016, the Saturn V remains the tallest, heaviest, and most powerful (highest total impulse) rocket ever brought to operational status, and holds records for the heaviest payload launched and largest payload capacity to low Earth orbit (LEO) of 140,000 kg (310,000 lb)

Although once you have the technology to craft D2 out of air and feed stock changing the formulation of the output shouldn't be too difficult.

Then keep on building nukes till we have enough electricity being generated to replace all those gasoline/diesel automobiles (trucks, trains, etc) with electric versions.

When you look at the chemical properties of diesel it's really, really hard to beat. It doesn't explode. It doesn't even burn at room temp without a lot of coaxing. It carries 46 MJ/kg.

If electricity really is free and plentiful we should have no problem making D2 out of thin air and trash. Fischer-Tropsch got the Germans through WWII. Just start using trash as feed stock and eat the inefficiencies.

With the right software hardware from a decade ago is still running. Stop buying the cheapest hardware you can find. Look for embedded systems for industrial environments. They might be a bit slower than what you're used to but they'll run for the next few decades just fine.


XPrize's New Challenge: Turn Air Into Water, Make More Than a Million Dollars ( 150

An anonymous reader shares a CNET report: If you can turn thin air into water, there may be more than $1 million in it for you. XPrize, which creates challenges that pit the brightest minds against one another, is hoping to set off a wave of new innovations in clean water -- and women's safety too. The company announced its Water Abundance XPrize and the Anu & Naveen Jain Women's Safety XPrize on Monday in New Delhi. The first competition will award $1.75 million to any team that can create a device able to produce at least 2,000 liters of water a day from the atmosphere, using completely renewable energy, for at most 2 cents a liter. Teams have up to two years to complete the challenge. India is at the center of the world's water crisis, with access to groundwater depleted in some northern and eastern parts of the country. Water has become so scarce in India that natural arsenic has infiltrated the soil and water in certain regions. While there are systems that can currently extract water from the atmosphere, many of them aren't energy-efficient, or generating enough water. "We know that overuse of groundwater resources are causing the water crisis and it's only getting worse," said Zenia Tata, XPrize's executive director of Global Expansion. The $1 million Women's Safety XPrize calls for an emergency alert system that women can use, even if they don't have access to their phones. The alert would have to be sent automatically and inconspicuously to emergency responders, within 90 seconds, at a cost of $40 or less a year. The device would have to work even in cases where there's no cellphone signal or internet access.

As long as their competition continues to not "get it"

Walmart (and grocery stores as a whole) have quite possibly the worst 'last mile' solution possible. Everything prior to shipping to the store is done as efficiently as possible. Walmart's logistics argues with truck OEMs over 0.1MPG because of how much it can save them across the fleet. They redesign boxes and liquid containers so you can fit more on a pallet.

All to be unboxed & unpallated by someone being paid minimum wage. To put it on a shelf where I have to take time out of my day to go, pull it off the shelf, put it in my cart and ring it up myself (or pay another person to do it), load it into my car and drive it home.

Some of our local farmers will even drop off meats and produce. If Walmart wants to get my business again give me a barcode gun and let me shop like people add stuff to their wedding registry. I'll walk through the store once, choose how often I want a product and when I want it delivered.

I went to Best Buy last week (once every ~6-months to see what is out) they were more than happy to point out that they price matched Amazon. I asked if they also had free delivery. Paid mileage to their store and compensated me for my time. (They don't). With Amazon (and other online retailers) goods show up at my doorstep.

I can't wait for a grocery chain (local, national, Amazon, I don't care) to carry a full store's worth of food and let me decide when I want it.

Submission + - A solution for DDOS packet flooding attacks (

dgallard writes: On October 21, 2016, a DDOS attack crippled access to major Web sites including Amazon and Netflix.

PEIP (Path Enhanced IP) extends the IP protocol to enable determining the router path of packets sent to a target host. Currently, there is no information to indicate which routers a packet traversed on its way to a destination (DDOS target) enabling use of forged source IP addresses to attack the target via packet flooding.

PEIP changes all that. Rather than attempting to prevent attack packets, instead, PEIP provides a way to rate-limit all packets based on their router path to a destination. In this way, DDOS attacks can be thwarted be simply only allowing them a limited amount of bandwith.

Submission + - "Splat" of Schiaparelli Mars lander likely found (

Tablizer writes: "Views from NASA’s Mars Reconnaissance Orbiter released Friday show the crash site where Europe’s experimental Schiaparelli lander fell to the red planet’s surface from a height of several miles, leaving a distinct dark patch on the Martian landscape...

The image from MRO’s context camera shows two new features attributed to the Schiaparelli spacecraft, including a large dark scar spanning an estimated 50 feet (15 meters) by 130 feet (40 meters). Schiaparelli’s ground team believes it is from the high-speed impact of the lander’s main body...

A little more than a half-mile (1 kilometer) to the south, a bright spot appears in the image, likely the 39-foot-diameter (12-meter) supersonic parachute and part of Schiaparelli’s heat shield, which released from the lander just before ESA lost contact."
