Navy Creates Fuel From Seawater

FishTankX Re:Energy inputs (256 comments)

Fascinating. So electrolysis is the main driving force of this reaction....

If they could somehow install nuclear plants capable of running a sulfur iodine cycle, they could probably achieve 50% efficency, probably enough to obviate the need for at-sea resupply.

Navy Creates Fuel From Seawater

FishTankX Re:Energy inputs (256 comments)

Probably. But many thermochemical processes fail to achieve 100% efficiency. So i'm not sure how efficient this one would work. And @$0.1/kw that's probably the figure for electricity, not thermal energy. I think most chemical conversion processes use thermal energy not electrolysis.

Navy Creates Fuel From Seawater

FishTankX Energy inputs (256 comments)

Assuming that this process is 10% efficent let's take a look at the numbers.

Let's say you can dedicate half of the 1.1GWT (thermal) of the nimitz to aviation fuel production, if you're holding off coast.

And let's assume conservativley that the process is 20% efficent.

Diesel (pretty close to JP1) has an energy density of 35 MJ/L. This means at 20% efficency you'll be needing 175mj to create 1 liter of JP1.

At 1/2 1GWT you're looking at about 3 liters of fuel per second, or about 172,000 liters a day, or about 40,000 gallons. The nimitz has about 3 million gallons of fuel capacity so the refueling time of the entire tank from 0 would be around 2 months. According to this article here

http://large.stanford.edu/cour... (Also about marine jet fuel fabrication, provides some of the hard numbers) 3 million gallons is enough to refuel the onboard fleet about 20 times. So onboard fuel production would provide 1/3 of a full tank of gas for each aircraft onboard per day. Not terribly good, or bad.

Operation Wants To Mine 10% of All New Bitcoins

FishTankX Re:I admire their spunk, but... (275 comments)

Perhaps somebody should create a folding at home/cancer research coin, that gives each person who dedicates CPU time a folding coin, with increasing difficulty. Once any research is commercialized with the results of the computations, a 50% share of the patent is disbursed to the coin holders. CPU calculations and GPU calculations would be separated and compensated differently. Like a CPU computation is worth 20x more than a GPU computation, because GPU computations can only solve certain problems and CPU computations are still needed.

If the bitcoin/litecoin swarm were dedicated like this to a research cause, the coins would gain inherent value once a commercialized therapy were implemented, like stocks, and would probably pay dividends, supporting a minimum price floor and adding a concrete value to the calculation based coins for the first time. No?

Fishing Line As Artificial "Muscle"

FishTankX Re: There is no energy input (111 comments)

Heat is the input energy. It takes heat to actuate the muscle. After it cools it stops resisting the tension. My guess is that heat is applied through nichrome wire. Although being able to actuate at 130c makes me think you could use polyethylene coils to make a waste heat recovery engine via a reciprocating pull on a flywheel

Meet the Electric Porsche From 1898

FishTankX Re: Generalizing much? (143 comments)

http://en.m.wikipedia.org/wiki...

Here Is the wikipedia article on lithium air batteries. If not 10x then atleast gasoline equivalent energy storage is possible. Are you saying that you would need a lithium hydrogen battery to reach 10x potential? The lithium air battery doesn't carry a cathode so it can hold more charge per weight so that's why I assumed it would live up to the 5-15x claim on wikipedia.

Meet the Electric Porsche From 1898

FishTankX Re:Generalizing much? (143 comments)

This may on the surface be true. But the primary technological challenge with electric vehicles is battery technology, and this has been under development for a century and a half. Maybe even 2. Even still, though rechargeable batteries have gone up in capacity maybe 10x, it is still not anywhere near competing with ICE vehicles cost effectively. That will come when the air-chemistry batteries hit the market, with another 10x increase in energy storage per volume/weight due to negating the need to carry your cathode. (or is it anode?)

Microsoft Reports Record Revenue

FishTankX XBox saves the day (289 comments)

Looks like for microsoft to preserve profitability it may have to continue to branch out of its core competency, windows. Perhaps it's following in Apples footsteps in a sense, branching away from personal computing to consumer electronics.

Will Electric Cars and Solar Power Make Gasoline and Utilities Obsolete?

FishTankX Re: Uh? (734 comments)

a forklift battery can be had for about 5k and stores like 30-50kwh of power and will work well within its 20 hour rate for the average house. no sense in using an electric car when forklift batteries are designes to run day in and day out for a decade in even more strenous conditions. And lord knows we have enough lead and sulfur. recondition or recycle when done and little environmental damage running into the future.

Intel Puts a PC Into an SD Card-Sized Casing

They'll just invent a loaf magazine and an autoloader belt. You could do it with a conveyer belt and an overhead heating element.

Ford Will Demo Solar-Charged Car At CES

FishTankX Re:Hope it doesn't melt the car! (179 comments)

Well actually what I see as the killer app for this is being able to run climate control in your vehicle and not having to worry about draining your batteries. Being able to run 300w AC power, while not spectacular, could keep you from roasting potentially. Especially if you put reflective panels in your windows when you leave.

Speaking of which, why has no car manufacturer bothered to make a car that can automatically hoist up a window sized aluminum plate with your windows when you park? Hmm...

Ford Will Demo Solar-Charged Car At CES

FishTankX Re:Hope it doesn't melt the car! (179 comments)

The obvious way around this is to have a heat exchanger under the solar panels, then use some energy to cool the solar panels through the radiator. A car's radiator should be able to handle ~2kw incoming heat load, with just a pump. It would help improve efficency as well, since solar panels charge better when they're cool.

The Japanese Mob Is Hiring Homeless People To Clean Up Fukushima

FishTankX Re: Genocide, prove otherwise. (90 comments)

Actually I lived in Aomori city in Aomori prefecture for 5 years. Are you from Japan? If so, you know it's not a super expensive place to live. But normally they wanted 1 months rent, security deposit, 1 months rent as a real estate agent fee, and 1 or 2 months rent (I forget which) as key money. (A gift to the landlord.)

My apartments base rent was 50,000 yen (`$500) and was not the most expensive place in the city. But worse case scenario that's still almost $3000, or close to 3 months salary for a minimum wage worker. Even if you lived with your parents, it might take a year to save enough to get into an apartment like that if you still want to have fun.

In Tokyo? Blech. minimum wage isn't that much higher, but rents are almost double in the city. You have to live in Chiba or some other suburb and have long commutes to get a good rate.
