Photosynthetic human

We should make our own food in our bodies


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.

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



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.

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.




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.

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

// 我强烈反对改变人类基因组。


// 这将是我们所知道的世界末日,


// 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

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%](

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? :)
