The full article is really worth a read.
I'll definitely check that out. It never ceases to amaze me that the smallest amount of a chemical (micrograms in the case of LSD) can completely alter your brain chemistry for hours on end.

That is great.

If they could invent solar panels that could be used like roofing shingles, siding or window screens , that would change the rules for architecture as well as energy consumption.

Yeah, I realize that solar energy is only valid during the day and when the sun is shining etc...but if you (we) could cut our energy consumption (fossil fuels, nuclear, petroleum or coal) , it would save the US billions of dollars a year in energy consumption, allowing that money to be used somewhere else in the economy.

Even if solar only works during the daytime, that's ok. If that reduces 50 percent of our consumption, I'll accept that as a check in the Win column.

Well, you're not necessarily consuming all the electricity as you're creating it. If the panels are efficient enough to create surplus energy, it could be stored for (literally) rainy days.

Perhaps. But I think Nick Sands was an exception to the rule.
When I think of illegal drug manufacturers cooking up illegal drugs, I think of college students reading instructions from the internet, a below average chemistry student that dropped out of school, a pharmacist that was fired from his job, a hillbilly cooking meth on his stove top and contaminating his entire house or an illiterate peasant using diesel fuel, antifreeze and his own piss to create cocaine. I don't want to stick anything in my body that does not meet FDA standards.

The Pineal gland is suppose to regulate a lot of those experiences.
It's too bad we can't have a pill (legal) that can tweak them when we want
them, or have an operation (like plastic surgery that is so popular) and make it permanent.

Experts say the pineal gland is the source that permits us to reach our higher selves and expanding consciousness. I'd love to tap into that baby, especially after some of the interesting dreams and meditations I have had.

'Most Accurate' cosmic simulation to date . How the hell do we have any idea if it's accurate or not? It should read 'Most Complex'.

Yeah or it could be sold back to the utility company for money !

Batteries for storage are great, but I imagine it would take a lot of batteries to keep the average house electrified.

However, batteries for solar storage are improving and getting cheaper

There's a lot of simple efficient means of energy storage you could use to bypass batteries, one i've often considered is using surplus energy to power a pump which lifts water up an incline and then running it as a turbine generator on the way down. southern california gets energy returns by doing that when they pump water up over the grapevine.

So you're turning the excess electricity into mechanical potential energy instead of storing it in a battery; I like that. I wonder how much you're loosing in the transfer though.

well motor efficiencies are about 90-95%, and the turbine efficiency also 90-97%

So worst case 81% efficient, best case 93%.

It's something i plan to utilize when building my post zombie apocalypse fortress.

Better yet, use a rain cistern to get even more water.

If you are using excess capacity that would otherwise go unused, does it really matter ? If you are using free energy from the Sun, it would concern me less than if I was paying for it from the utility company.

How come when they build a hyrdoelectric plant they build turbines that the water flows through but never build a second set of turbines downstream and then a third. It seems like they could keep using the water more than once to produce additional electricity.

Even if the turbines would lose efficiency, it would still be better to build a second set of turbines that are 50 percent efficient and get 50 percent more electricity from the same footprint, than build another power plant.

If you REALLY want to go green you could also consider using grey water from your septic tank....

Well there has to be a certain cost benefit, if this rig costs you 5k to build and operates at 40% efficiency, you may have been better off just mitigating the whole middle phase and buying 5k in batteries for your house.

Which by the way is very doable, house energy requirements are surprisingly small when compared to what it takes in batteries for an electric car.

The cost benefit of doing a second dam are minimal, because you couldn't simply flow it through some more turbine sections and get more power out of it, you'd have to build more mini-dams, and the energy potential at each stage in a dam relies on the PE=MGH, and that H is the ***8710;H, not absolute. Unless you're implying extracting energy from the post dam water due to its velocity, which still wouldn't be very efficient.

Turbine efficiency is determined independent of power output, the turbine will always be 90-97% efficient, the question will be is there a sufficient kinetic energy source (water) to make it worthwhile building, i think the answer to that is no.

So you are saying that the speed of the water is what important, not the volume of water passing through ?

It's all about the amount of stored energy. More volume at a lower height = less volume at a larger height. That's undesired to what he was saying though. The point he was making is that efficiency has nothing to do with power output.

Edit: unrelated, not undesired...autocorrect

Danke!

Also cool fact about kinetic energy storage, back in the day when my dad worked at LBL, they'd actually store energy for their particle accelerators in massive flywheels.

Boston Dynamics has taken the wraps off its newest prototype combat escort, AlphaDog, which was developed with funding from DARPA and the US Marine Corps. Waltham, Massachusetts-based Boston Dynamics last week revealed the video that shows AlphaDog's capabilities for troop support. Those who have seen the video are calling the quadruped robot such names as Mule Poodle, Monster Mutt and BigDog-on-Steroids, but AlphaDog is its name. The robot is described further as the prototype for the formally named LS3. The latter stands for Legged Squad Support System.
