  1. Re:Not a new idea. on DARPA Proposes Ripping Up Dead Satellites To Make New Ones · · Score: 1

    Actually, a reusable space plane would be...

    considerably more expensive than simply launching a new satellite, completely defeating the purpose.

    Yeah, depending how long it sticks around we're probably going to see an increase in cancer incidence in that area.

    I see what you're getting at. Different types of radiation don't do different types of damage. The harmful effect is the damage or destruction of molecules. Doses aren't internal or external. Only the source is. Where the radiation comes from doesn't affect how much damage it does.

    Tell me, what argument is GP trivializing? It can't be the argument to not act like a bunch of headless chickens whenever someone says "radiation" because he nailed that.

    also disregard that K-40 is a beta emitter...

    The sievert is the radiation dose equivalent to one gray of gamma rays in tissue damage. Type doesn't matter.

    That said, 7uSv/h is... concerning. Are you sure this isn't the radium bottles they dug up?

  10. Re:For a low-power 8-bit MC with 2.5k RAM... on Microtouch: 8-bit Open Source Media Device · · Score: 1

    The AVR is a Harvard device, the one they're using has 32k of flash. The return stack is in ram so preemptive multitasking is possible. There is indirect with displacement addressing so data can be position independent. There's no memory protection though. You could fit TCP/IP on it, probably over a communications USB class, but I don't think you could fit much more than ftp/telnet on top of it.

  11. Re:A desert on Why Mars Is Not the Best Place To Look For Life · · Score: 1

    Mars' GEO is 17,000km. The whole point is that the centre of gravity is in geostationary orbit. A space elevator on Earth would be 72,000km long.

    One of the best ways of inserting a gene into an animal cell is with a virus. Many types of bacteria can accept free floating DNA. DNA for a virus is introduced but modified so that instead of DNA to make more viruses, the virus contains the gene to be inserted. You just need to keep feeding the bacteria for an infinite supply.

    It depends on the charging system. With the right electronics you can regeneratively brake as fast as you can accelerate.

  18. Re:What expected life span means... on DNA Sequenced of Woman Who Lived To 115 · · Score: 1

    Cancerous cell lines are an evolutionary dead end.* They can evolve within the host, but once the host dies all adaptations are lost.

    One thing that I think shows promise for bacterial infections is phage therapy, researched extensively in the Soviet Union. Viruses are used to attack bacteria with the benefit that the virus evolves new ways to attack the bacteria as the bacteria evolves defences against it. Viruses are highly specific, so they won't attack the host.

    *There are a very few exceptions. Some cell lines can evolve the ability to survive outside the host, becoming "immortal" cell lines. They are only dangerous to the original host however, otherwise acting as an independent organism.

    I'm not sure you realize how cheap this could be. Currently, the best way to insert a gene into an animal cell is with a virus.

  20. Re:All for it, if... on Hacking the Nissan Leaf EV · · Score: 1

    Yeah, I said that wrong. What I meant to say is that electric cars do better in cities compared to highway driving compared to gas cars. Gentle acceleration isn't important, as long as you're not flooring it. Long breaking does help a lot, but this is more of a psychological problem. If you wait until the last minute to break, you've just reached the red light faster and spend more time waiting.

    There are lots of people who do 65 on the highway maybe once a month, but fight gridlock almost daily. I admit electric cars aren't the silver bullet, but they make sense for some.

  21. Re:A desert on Why Mars Is Not the Best Place To Look For Life · · Score: 1

    I'm not sure you understand how much of an undertaking a space elevator is. The sheer mass precludes shipping materials from earth. You have to build mines, refineries and steel mills on mars. Then you start building the 34,000km tower.

  22. Re:genset trailers are DIY only on Hacking the Nissan Leaf EV · · Score: 1

    Looks like the AC Propulsion model was a complete success right up until the Rav4EV was discontinued. That pusher sounds downright dangerous.

  23. Re:Better you say? on Hacking the Nissan Leaf EV · · Score: 1

    Gah, you're entirely correct. Precise, not accurate. I've been trying to train myself to remember the difference, but it's not working.

    I made the assumption that (like almost anything with an Li-ion battery) the car computer just passes along the value given by the battery's microcontroller. The microcontroller prevents the battery from being discharged to the point of damage. I don't think this hack will break anything, but I don't like it either. If you need to zoom in to see if you can make it home to charge, you're doing it wrong.

  24. Re:Extended range on Hacking the Nissan Leaf EV · · Score: 1

    Plans for the transition period (lots of electric cars on the road, but no 5 minute charging yet) is a small, rent-able trailer with a generator and engine on it. The engine can be tuned for high efficiency at a single speed. This lets you use an electric car for your daily commute and still use it for the one day a month or so you need to go farther.
