Comment Fixed capacity (Score 1) 81

One important point that others above have alluded to but haven't outright stated:

While the exponential scaling of rocket equation is an important limiting issue when building larger and larger rockets, for any given rocket (or rocket configuration) the payload capacity is fixed. If you have a payload that is too large for a Falcon 1Pegasus, but doesn't need the full capacity of a Falcon 9, all that extra capacity goes to waste. It costs essentially the same amount to launch a Falcon 9 at 60% capacity as it does to launch it at 90% capacity. You can share payload with multiple customers, but that limits which orbits they can use.

Space X can calculate how much weight the recovery system and fuel requires and how much money they can save by reusing the first stage, and give a discount to customers who give up that additional payload capacity. If there is a market for those lower cost launches, then great. If not, then keep treating the 1st stage as disposable.

Running a business like this takes a lot of work, and for it to succeed well enough to actually get working rockets off the ground you need to attract top-notch engineers who believe that working for you isn't just a waste of their time (more than a billionaire's plaything), and management that can create the right environment for them to succeed without blowing through your money for nothing. It is much less expensive, less risky and less time consuming to just pay Russia for a thrill ride than to create your own rocket company. So I can understand why most would choose to go that route, and leave the latter for those who genuinely want to shake up the market.

Comment Re:it can be air filled (Score 2) 200

That said, the total payload mass that the ship could support is roughly the same whether it is inside the airship or outside in a gondola, and the more space you want to make available for use, the more mass you would have to dedicate to structure rather than payload. So it would be less cramped than a tiny capsule, but you would still need large expanses of mostly empty space to provide the needed buoyancy.

In practice, it might be better to have a balloon filled with a less dense gas to decrease the total volume needed to support the desired payload, and then have an attached air-filled "gondola" that is nearly as large as the balloon.

"Fortunately, most open minded people are willing to accept a vast amount of statistical evidence as proof."
Then get back to me when your sample size is much larger...
Talk about your dumb analogies. BTW you are totally wrong. By the 1980s tobacco smoke had been studied and found to be full of known cancerogenic compounds. They did have mass spectrometers in the 1980s after all.

You like most people are confusing weather with climate. A single drought can not be attributed to climate change it would take a lot more data aka many decades of data.

" but that didn't prevent climate researchers from claiming Katrina-level events will drastically increase in frequency"
I think you are confusing advocates with researchers.
Fear sells after all.

What is so annoying is that most climate change advocates are as clueless about climate as those that deny climate change.
Every hot summer, warm winter, flood, drought or hurricane is proof... No it is weather.
So when you have a slow hurricane season, a drought ends, or an extremely cold winter you have proof that climate change is not happening. No it is just weather people...

The arrogant ignorance of the clueless climate change advocates do more harm than can imagined.

 

Comment Guess you forgot F-22 Interceptor for the Genesis (Score 1) 222

And it's predecessor, LHX Attack Chopper. Two games that managed full filled-polygon 3D engines on just a 68000 processor (AFAIK there is no coprocesor in the cartridge).

While most ground targets were just boxes, the plane models were surprisingly detailed. Star Fox the first 3D game on consoles? Hah, I was playing F-22 for years before Star Fox came along :D

I hate the over use of drones but RC aircraft do fall out of the sky.
What people don't get is that RC aircraft can be pretty big and dangerous.
https://www.youtube.com/watch?...
People already fly jet RC aircraft that fly at well over 100 mph and mass over 50lbs.
Yes they can kill people which is why they have rules.

You are right that most "drones" are not large or fast but they can be. Maybe a rule of under 5 lbs and under 20 mph for unregulated drones is in order.
 

Comment Re:JPEG2000 replaced JPEG (Score 4, Informative) 377

You don't have to wait for someone to pop out of the woodworks. BPG is nothing but a still frame of HEVC video which is patented up the ass. Bellard and other open source video authors are accustomed to ignoring the patent situation because they don't really have a choice if you want to be interoperable, but that isn't an excuse for creating patent problems in a field where there are already widespread royalty free standards (JPEG, PNG).
