SpaceX Executive Calls For $22-25 Billion NASA Budget

jklovanc Re:When I was born... (114 comments)

Without the military the scientific research would be owned by some other country. If one becomes a rich weak country one becomes a ripe target.

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

jklovanc Re:Stable? (117 comments)

My original statement still stands; 150 cycles is not "stable". It is just less unstable than previous attempts. When that can show 2000-3000 cycles then we can talk about "stable".

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

jklovanc Re:Stable? (117 comments)

You're asking too much from a research project.

I think you ask too little. What get me are quotes like this;

The team is looking at a price point of $25,000 for an EV battery range of 300 miles, which would be competitive with a 40 mpg gasmobile.

They haven't even shown that their battery will last six months at a charge cycle a day. As there is no mention of it I doubt they have built a full EV scale battery yet. There is a huge gulf between what they have and what they are "looking at". If they haven't even done long term cycle studies they surly have not looked into the cost of mass production. How can they come up with battery costs? Had they stopped at what they had proven then I would not be so critical. By defecting attention from what they actually have done to what they what you to think they have done sounds fishy to me.

I have to tell my math story again.
There is an economist, and engineer on a train going to Glasgow.
The economist looked out the window and sees some sheep with black wool and says "Wow, all of the sheep in Scotland are black".
The engineer looks out the window and says "Some of the sheep in Scotland are black".
The mathematician looks out and says "There exists in Scotland at lest one field where there are sheep that are black on at lest one side".
All they could see was one field and one side of each sheep. Anything else is not proven.

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

jklovanc Re:Stable? (117 comments)

There is a huge difference between a "hater" and a "skeptic". Doubling from a absolutely useless number of cycles to a completely useless number if cycles is significant but not useful. I like reading stuff in the load but touting this kind of improvement as something that will revolutionizes electric vehicle pricing is much too soon. It appears to be a marketing ploy to gain investment in a sham. The sooner shams are expose the sooner investment goes into areas of real possibility.

World's Largest Amphibious Aircraft Goes Into Production In China

jklovanc Re:Not so big (85 comments)

Not amphibious

Because of its size, the Martin Mars can only land on and scoop up water from about 113 bodies of water in B.C.

World's Largest Amphibious Aircraft Goes Into Production In China

jklovanc Re:The Spruce Goose is your comparison? (85 comments)

If you look closely at the Mars maintenance picture you will see a couple of things. First the tread on the wheels under the aircraft are quite aggressive. I have never seen that kind of tread on landing gear. Second the wing pontoons are supported by scaffolding and not wheels. My theory is that the Mars has the facility to attach dollies to the air frame to allow it to be pulled out of the water and those are not landing gear.

I also looked up a number of articles and the Mars is always referred to as a flying boat and not an amphibious aircraft. The final kicker is that BC is retiring it's Martin Mars aircraft and here is a quote from an article explaining the decision;

Because of its size, the Martin Mars can only land on and scoop up water from about 113 bodies of water in B.C.

The Martin Mars is not amphibious.

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

jklovanc Stable? (117 comments)

Stable is a relative term. Stable compared to what? It is the same thing I think of when someone says "soon". Are we talking "soon" compared to a fruit fly's life or "soon" compared to galactic time?
From the article;

According to Stanford, the results so far look promising. In tests the new lithium anode reached 99 percent efficiency over the course of 150 charge/discharge cycles.

150 charge/discharge cycles is not very much. That is only 5 months use. Who is to say that the battery does not degrade to 50% at 200 cycles? What about 3,000 cycles? I bet they have done that test a few times. They seem to be hiding something. Sure it may be stable compared to current lithium anode technology but is it stable compared to other lithium ion battery technology?

Show me the complete data or I will assume you are hiding something to make your technology look better and garner investment even though you know the technology has a fatal flaw.

SpaceX Executive Calls For $22-25 Billion NASA Budget

jklovanc Re:When I was born... (114 comments)

yet we refuse to spend more on space industry than we do on our aircraft carrier program (old Nimitz class cost about 4.5 billion - and we have 11 of them).

The Nimitz program produced ten carriers between 1968 and 2006. That is 38 years for a yearly budget of $1.8B. That is approximately 10% of the NASA budget. There are now also 10 large carriers in service. Comparing a long project with a single year budget is inaccurate.

Bad "Buss Duct" Causes Week-long Closure of 5,000 Employee Federal Complex

Which during the hot months that did in the mornings and evenings and not a 9-5 schedule so they can coordinate with the rest of the country.

Bad "Buss Duct" Causes Week-long Closure of 5,000 Employee Federal Complex

jklovanc Not just AC (124 comments)

Here is a link to a story about the outage.

Therefore, the chiller plant and a large portion of the building’s electrical grid were rendered inoperable

It is also difficult to work without lights, computers, routers, PBX, etc.

The Army Is 3D Printing Warheads

jklovanc Re:GPLv4 - the good public license? (140 comments)

Actually you are incorrect as the top two languages are Mandarin and Spanish. The Mandarin speakers would be speaking Japanese and many of the Spanish would be speaking German. My point was that WW2 would have turned out very differently if the US had not manufactured arms and non-native languages would be imposed by conquerors..

jklovanc Re:GPLv4 - the good public license? (140 comments)

Not quite. Has the US exterminated 8 million Jews or 5 million Ukrainians? Is Europe Democratic or Communist? Does Kuwait, Israel, South Korea and Taiwan still exist? Is Tunisia still controlled by Qaddafi? You are very self centered if you only look at the US.

Most of the things you state do not effect the average person.

Wow did you misunderstand me. I was trying to say that the OP does not want to help weapons but is fine having them used by others to protect him. I would call that a hypocrite. I am not a gunophobe the OP is.

This comes from someone who just does not understand that without weapons manufacture most of the world would be speaking German or Russian by now.

"Often" aka not always. By the way, that phrase was added much later than the original.

No, I am saying that it tries to be too many things, does all of them poorly and ends up being useful to none.
