Tobacco Virus Could Boost Li Batteries

siliconbits alerts us to the possible use of one of the world's most destructive naturally occurring scourges, the tobacco mosaic virus, to boost the capacity of lithium ion batteries by 10 times. It seems the virus can be made to attach itself to the electrodes in a lithium cell perpendicularly, increasing the surface area of the electrode and greatly improving the battery's capacity to store energy. PhysOrg has some more detail on virus-enhanced batteries. Four years ago we discussed the use of the tobacco mosaic virus to enable fast-switching transistors.

      Considering the frequency of dopamine-related mutations in humans that seem to require dopaminergic drugs for treatment (And our culture's current paralyzing fear of dopaminergics), it seems far too early to label tobacco a universal scourge.

      How many murders or confrontations in general have been prevented by a dose of nicotine? How many suicides prevented due to its acute antidepressant effects? It's very difficult to quantify nicotine's benefits, and its negative effects are much more visible.

      Really, it depends on what way you're speaking. In a horticultural (applied plant science)/culinary sense, vegetables are plant parts usually used in savory food, typically annuals, regardless if what you eat is leaf, petiole, root, tuber, stem, flower head, bud, seed, fruit, ect. Botanically, pure plant science, it's true that the term vegetable has no meaning. Confusion can arise with things like tomatoes because the term fruit has different meanings; as a horticultural or culinary term, it is something sweet, typically from a (woody) perennial, whereas botanically speaking it means anything with seeds in it, like tomatoes, peppers, eggplant, squash, pea pods, green beans, peanuts, cucumbers, ect. The study of vegetables is a field of itself: olericulture. So, squash & tomato are indeed vegetables; botanical fruit and horticultural vegetable are not mutually exclusive terms. That's true in reverse that a horticultural fruit is not necessarily a botanical one as well. If you ate a cashew apple, Japanese raisin, native cherry, or plum pine you'd probably think them fruits, but they're not.

      Bottom line, it's like asking if a chicken is a type of poultry or a bird.

    Balderdash! The key to preparing eggplant is the following two steps:

    1) Slice the eggplant into ~ 1.5 cm - 2 cm slices. Salt one side of each slice. Reassemble eggplant, wrapping with cling wrap to hold it together. Let it rest for ~30 minutes until all the bitter juices leech out, and then wipe each slice dry.

    2) Roast or grill eggplant for a couple minutes, until it looks like it has started cooking.

    Then, do whatever you want with it.

    Also, it helps to know that the eggplant has "male" and "female" fruit, and that the female fruit has a more bitter flavor.

  17. 10-fold increase? by bored_engineer · · Score: 3, Interesting

    Gasoline has an energy density of about 34 MJ/L, while current Li-ion batteries have an energy density of around 0.7 MJ/L. If this comes to fruition, we'll have batteries with about 1/5th of the energy density of gasoline. That's quite amazing, in my opinion.

    What if that battery is pierced, though? I know that the Tesla rig uses a slew of small cells. Do other electric cars like the Volt or the Leaf do the same thing? It seems to me that a number of small cells might present less of a problem, though that would drive the energy density of a battery pack down.
