Photosynthetic human

We should make our own food in our bodies

YAML 问题

If we could splice chlorophyll genes into our genome so that our bodies surfaces are photosynthetic we could generate food from our skin.

We would have to sit in the sun for hours a day but we could use a computer simultaneously.

我们可以修改我们的身体来像植物一样长出叶子。

We could modify our bodies to grow foliage like a plant.


巧克力的所有成分都来自光合作用。这就是它的强大。

当然,我们将不得不像树木一样保持静止,但我们的文明会更加稳定,需求也会减少。

All the ingredients of chocolate came from photosynthesis. That's how powerful it is.

Sure we would have to stay still like trees but our civilization would be far more stable and there would be less want.

chronological,

基因改造应该有一个单独的主题。我已经在 self-modifcation 上开始了这样的话题。

The genetic modification should have a separate topic. I've started such topic here on self-modifcation.


最后,生为一只狗并不意味着你的余生都必须是一只狗,最后,我们将能够取代我们的基因限制。

修改基因组只会影响下一代,而不是个人,而是他的后代。我们有什么样的动机来对我们的孩子这样做?我猜想,生产奴隶,对某些任务高度专业化。另一个场景是有钱人用超感官来增强他们的孩子,创造一个大师种族。创造一个人类的战士亚种怎么样?你准备好与他们战斗了吗?这些预测并不难。

这就像可以修改自己代码的软件。一开始可能会遵循一些规则,但随后这些规则可能会发生变化。这太令人困惑了。此外,您将如何处理不幸但不可避免的错误。哎呀,我们刚刚在可怕的藻类中创造了一个物种,永远要对付。祝你好运。

finally, being born a dog doesn't mean that you'll have to be a dog for the rest of your life, finally, we will be able to supersede our genetic limitations.

Modifying genome will affect only the next generation, not the individual, but his offspring. What kinda motivation would we have to do that to our children? I'd guess, to produce slaves, highly specialized for some tasks. Another scenario is rich people enhancing their children with super senses, creating a master race. How about creating a warrior subspecies of humans? Are you ready to fight them? These are not hard predictions to make.

It's like software that can modify its own code. Maybe by some rules at first, but then those rules will be subject to change. It's just too confusing. Also, how would you deal with unfortunate, but inevitable mistakes. Woops, we just created a species in f monstrous phycopaths, for ever to deal with. Good luck.

skihappy,

是的,我们进化出过去的植物来消耗高能量食物是有原因的。这就是树木不动的原因。这超出了他们的能量预算。我们可以自由行动,但必须寻找高能量食物。不能两全。如果有的话,我们会看到一些小动物在做这件事

Yeah, there's a reason why we evolved passed plants, to consume high energy foods. This is why trees don't move. It's out of their energy budget. We are free to move, but burdened by necessity to find high energy food. Can't have it both ways. If there was, we would see some critter doing it

skihappy,

// 我强烈反对改变人类基因组。

为什么这样?我实际上是为了在基因和更高层次上进行自我改造的自由和权利。

// 这将是我们所知道的世界末日,

正如我们所知,这已经是世界末日了,这项技术存在真是太好了——最后,生为一只狗并不意味着你的余生都必须是一只狗,最后,我们将能够取代我们的基因限制。

// I'm highly opposed to altering human genome.

Why so? I'm actually for freedoms and rights of self-modification at genetic and higher levels.

// It'll be the end of the world as we know it,

It already is the end of the world as we know it, it's great that this technology exists -- finally, being born a dog doesn't mean that you'll have to be a dog for the rest of your life, finally, we will be able to supersede our genetic limitations.


但我们将成为别的东西,不再是人类。我想保持人性。我不认为修改我们的基因组并将我们分成 n 个亚种是一个好主意。只是被分成不同肤色的种族就够复杂了。 我强烈反对改变人类基因组。拥有这项技术是一个非常可怕的想法。正如我们所知,这将是世界末日,我希望到那时我会离开,但这可能是不可避免的

But we gonna be something else, not human any more. I wanna stay human. I don't think tinkering with our genome and splitting us at n subspecies is a good idea. It's complicated enough just being split into races of different skin color. I'm highly opposed to altering human genome. It's a very scary thought of having this tech available. It'll be the end of the world as we know it, and I hope I'll be gone by then, but it's prbly inevitable

skihappy,

嗯,是的,考虑到太阳能大约是。 1.36 kW/平方米,而人影的面积是 0.2 m^2,您将获得最大 270 W 的功率,并且您必须为晚上存钱。问题是最大总光合效率为 [3 到 6%](http://www.fao.org/3/w7241e/w7241e05.htm

Well, yeah, given that solar power is approx. 1.36 kW/square meter, and the area of human shadow is say, 0.2 m^2, you'd be getting 270 W of power at max., and you'd have to save for the night. The problem is that maximum overall photosynthetic efficiency is of 3 to 6% of total solar radiation, which is then equivalent to 0.016 kW of power. So, unless there's a better photosynthetic chemistry, being like a tree doesn't seem very nice. A 100 g bar of chocolate, that I've just eaten, has 2202 kJ (0.6 kWh) of energy, so, I'd need to sit under the sunshine for 37.5 hours straight to get equivalent amount of energy via photosynthesis.

Oh, and where is my electric battery instead of stomach? :)
