I've known people on the streets NOT due to drugs. Such a blanket statement seems socially biased and somewhat unfair to the homeless. It also paints a negative picture of all who are homeless. I was homeless once. For six weeks. And it wasn't due to drugs. [edit] And no - I didn't live in a hotel or other sort of arrangement. We sheltered for those six weeks. The church helped us get back up and going. And getting a job at Little Caesars helped. [end edit]

Granted, it's been a while since I've visited Yosemite but the stench of human urine does seem to bely the fact that there are some pigs of people out there.

I do agree, stealing power from the power company is wrong. I just thought it was a cool idea for recharging a drone in flight. I can imagine the power company using such drones to inspect their transmission lines with a drone spending several hours airborne while humans remain safe on the ground monitoring the inspection. That may be the first most practical use for such a drone. Another potential use could be by the DEA (Drug Enforcement Agency) to patrol borders. A quick in-flight recharge and the coverage continues. I'd be in favor of that. And I'm sure the military would pay a premium for the privilage of charging on the go.

While there are those who take advantage of the situation when they can - there are far more who wouldn't.

Come walk the streets here to see the interaction of drugs and homelessness. Something as common as bottle returns created drug hangouts.

Seen it in SLC, LA, NYC and a few other places. Lots of drugs - yes - I've seen that. I don't deny your observations. But I've seen others as well who were not on drugs.

Nobody denys that but the druggie is the rotten apple that spoils the rest. We created a cancer by our normalization of deviance that infects all.

 

@WBahn You're a moderator? I feel like you're being hostile toward me.

How am I being hostile? By disagreeing with you or by pointing out what I see as flaws with your position?

Fine. Goodbye.

Didn't say you ARE being hostile, I said I FEEL like you're being hostile. Perhaps I'm over reacting. No need for "Fine. Goodbye."

That is pretty cool...nice natural movements.

 

Oxygen for Mars
Direct splitting: Electrochemical process uses carbon dioxide to produce oxygen​

Use of an optimized RuCo catalyst allows for a very high yield of O2, over 98.6 %, significantly exceeding the efficiency of natural photosynthesis.

They don't say exactly what the 98.6% means. It's given as a yield (separation of oxygen from X molecule containing oxygen and something else) from some process (yield is important when the raw material is scarce or expensive like semiconductor die in a fab) but not as the energy efficiency of the end to end process for producing oxygen.
Photosynthesis DOESN’T directly split CO2.

Splitting a stable molecule like CO2 it likely not to be very efficient energy wise. If you have a Fusion reactor on Mars then that might solve the splitting energy needs.

https://en.wikipedia.org/wiki/Photosynthetic_efficiency

The photosynthetic efficiency (i.e. oxygenic photosynthesis efficiency) is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae.

Artificial Carbon Neutrality Through Aprotic CO2 Splitting

Global climate change mitigation necessitates global efforts to reduce CO2 emissions. Natural photosynthesis exemplifies an ingenious approach to carbon neutrality, converting CO2 into O2 and glucose through light and dark reactions. Inspired by the hydrogen-involved processes in photosynthesis, an aprotic electrochemical strategy for CO2 splitting into O2 and carbon using lithium as a reducing mediator is presented. The designed electrochemical device features a gas cathode with a nanoscale Co catalyst and a metallic lithium anode. When CO2 is introduced to the cathode, it undergoes a two-step lithium-related electrochemical reduction, converting it sequentially into Li2CO3 and Li2O. Li2O is then oxidized to produce O2 gas at the expense of renewable electrical energy. This process achieves an impressive O2 yield exceeding 94.7%, significantly outperforming the efficiency of natural photosynthesis. Moreover, the O2 yield can be further increased to 98.6% by employing an optimized RuCo catalyst. This study offers a new practical and controllable pathway to produce O2 from CO2, strongly promoting the sustainable development of human society for realizing carbon neutrality as well as exploring and conquering nature.

An answer I've seems that matches most energy required calculations for splitting.

 

I like cool pictures like this one.

 

Tesla optimus vs Boston dynamics:

 

That's about as realistic as this for near future uses.

That's a neat view. Wish I could shoot half that well.

Very lucky guy. Those .50 bullets can bounce back with a lot of energy. Fear the whistle.
