Because it's more expensive than it's worth. Maybe one day my floor panels will make use of a geothermal generator, but right now it's not an economical option.

>We talk about renewable energy ideas

You mean like new tech or just existing tech being used? I think pretty much everything has been invented that can be used, but not everything has energy harvesting applied to it for the mainstream consumer.

It'd be neat to have wearable energy harvesting stuff.

How about shoes that have Piezoelectric devices embedded in their soles that create electricity when you walk. There are a few DIY devices that use little dc motors to harvest energy, there's some that you Velcro a device to the shoe that creates power (kind of like a shake flashlight), and there are ones like what I am talking about using Piezoelectric stuff.

The voltage can be high in this stuff, but the overall power is extremely low. So they are only good for charging up super capacitors or very low power phone devices.

If this guy's company can figure out how to make and utilize those graphene cables, this technology will be amazing. They could make what amounts to as optic fibers for thermal energy from inside the Earth. The bore hole would be tiny, but could transfer a lot of heat. Because of its small relative size, you'd not be affecting the Earth much at all if any.

>>7986539
corrosion is a big problem, also distances to drill

There has been some talk here in Norway of teaming up with some of the "green power"-people in the north of Scotland i think. The idea is to use the excess power generated by waves/wind during of-peak(at night and so) to make liquid hydrogen. It would be a way of storing the energy instead of having to toss it away at boiling water or similar

https://www.eia.gov/tools/faqs/faq.cfm?id=97&t=3

That's under 10kw solar panel array needed in the shitty dark parts of the USA (4.14 solar index average). That's a range of 87 to 116 square meters of solar panel area. Most systems use far less because the houses use far less energy. That's because people who do make the switch to solar are more conscientious of their power usage prior to going solar and they live in areas with more sunlight per day. Thus, normally only need 30 square meters max, which fits on most average sized house roofs.

The point is, over 1 million homes have solar panels in the USA and 10,000s more per year are getting it. It is a massive trending bubble right now.

Personally, I am energy conscientious so that my electric bill is only about $35 per month. Which makes it so low that getting solar wouldn't ever be able to pay for itself before losing efficiency/breaking and needing to be replace; assuming a grid-tie system that didn't have batteries. Batteries simply make it absurd to do for me.

>>7986539
Can't remember the equation but you get a tiny amount of energy from them in relation to the energy you would expend drilling and all of the process involved in actually getting the geothermal energy harnessed

It is, but they are taking too long to bring it to the consumer market. They seem to be waffling over it only being 10% efficient and holding it back merely because of that.

You still need wires and a conductive layer under the paint. But, you won't be limited by shape anymore. Cars, houses, smartphone, etc could use it.

Holy fuck that curry nigger shilling water desalination. The math is total bullshit, you'd need a 10GW power plant to power just one of those gay ass boats. And the absolute madman wants to build hundreds. California alone spends 1500 times more than that ship can make every day.

All new tech is not financially feasible at first and very expensive. But, you have to make it, use it, redesign it, and manufacture it in bulk to get the costs down to proper economically viable levels. That's just how things work. The stuff in that video is more for investors than end users. Which is why you can't find links for end users to acquire any of the stuff in the video. Though, that bicycle has come a long long way in design since that video was made and is nearly ready to distribute.

Just look at the design of this device. From conception to final model it goes through all manner of changes and cost levels. Over the years, it will be refined as more people use it/manufacture it, and give feedback for it.

Yeah but you get to eat tasty food

>>7987508
>You'd do better just drying and burning the food to run a heat engine.

Fallacy. You are only looking at the end result of one aspect and not taking into account of everything else. Here's a small flow chart of how to properly utilize food and human-generated energy:

food crops > human consumption > human-generated energy > human waste > biomethane digestor > biomethane (used for making electric or domestic heating) and high-nitrogen fertilizer > growing more food crops using the high-nitrogen fertilizer

Your way would be:

crops > burning for electrical energy > no cycle, just burning up a resource

The food crops to more food crop cycle in the first flow chart is more efficient in the long run because you actually get more use out of the crops, are able to grow more crops with it, and people become healthier or maintain their health doing it. This hinges directly on the use of the microbes in the biomethane digester. Without that step, it wouldn't be worth it.

I mean, I'd rather eat food and have electric than to burn my food, go hungry, and have electric.

>>7991668

The trouble of lightining is that it is to random. You can't place a few lightning collectors and just hope It's gonna hit there. You can't cover every surface of the Earth with lighting collectors either.

Besides iirc is vital to the proper functioning of our ecosystem on Earth. Wonder what would happen if you removed it out of the equation.

>>7991775
>That'd be cool but how does one harness 100TW of energy instantly?

you don't. you build an artificial cloud and tether it with a conductor.

>>7991791
No, how do you actually use the energy? Just getting a lightning strike is pretty easy, but turning that into usable energy is the hard part.

I'm sure it needs something like a massive bank of super capacitors.

All of these are really just stepping stones for the end goal - the fusion reactor. That's the ultimate power generatior in the universe. Unless we someone figure out a way to harness the power of black holes. I think that would be tier 4 civilization on Michiku Kaka crazy scale

>The IEA estimates that, in 2013, total world energy consumption was 13,541 Mtoe, or 5.67×10^20 joules, equal to an average power consumption of 18.0 terawatts.
One of my profs said that the net power output of the shit decaying inside the Earth is about 40 terawatts, so the short answer is that there is not enough output to cover all of our needs. Of course the fact that you can't cover all of it with it doesn't mean we shouldn't use it, but obviously it can't cover a significant portion of it so it's not that interesting.
For example, the amount of power we receive from the Sun is in the petawatt range, fusion is basically unlimited too.

>>7991868
>One of my profs said that the net power output of the shit decaying inside the Earth is about 40 terawatts,

And, he's a complete idiot.

>>7991880
You want to elaborate on that, or are you just here to shitpost?

>>7991884
There's an estimated 10 to the 31st power joules of energy inside the Earth. The heat escapes to the surface at about 47 terawatts. That doesn't mean it can't output more energy if you start drilling holes and shoving them full of graphene cables. You essentially start poking holes in the insulation of an oven mitt and you realize that you can get burned.

>>7991868
>Sun is in the petawatt range

89.3 petawatts reaches the surface.

>>7986494
>I am currently working on the circuit intended to create said electricity.

Probably, but you won't produce much. What program are you using to design your circuit?

>>7991763
Don't even try that "muh improving tech" shit on me nigger. There's a fundamental, physical limit on energy required to distill water. Let's take the theoretical minimum (real world values are at least an order of magnitude higher) of around 1kWh/m3 for advanced tech, not basic distillation like in the video.

10^8 liters is 10^5 m3, so at the bare minimum 10^5 kWh/day (~5MW).
Daily consumption of water in California is around 1.5*10^8 m3, so in order to scale it up to a level of state, you need around 1500 of such ships, using a total of 60 GW of power.
Let's just look at the cost of implementing this.
An average tanker, without the meme distillers is between 50 and 100 million USD. Thus, a 200,000 Dwt ship can carry that much distillers which we can assume to be at least as expensive as scrap metal (and realistically two orders of magnitude more), so they are 20 millions USD per ship. Let's make it easy as just take a single complete ship to be around 100 million.
So, our fleet will cost 1500*$100mm=$150 billion. The cost of installing 60 1GW of nuclear is, let's be generous here, 60*$5bn = $300 bn for a grand total of $450bn.
I wonder about the ROI:
In 50 years it will produce 50*365*1500*10^5=2.7*10^12m3 of water. That gives a surprisingly low estimate of $0.17/m3.
Numbers above are not including building storage, pumping, cost of maintenance, personnel and other real life nuisances like upfront cost being likely an order of magnitude higher.

So the best case scenario gives us long term relatively competitive prices of water, but at the upfront cost of half a fucking trillion just for the state of california.

>>7991775
>>7991791
>>7991814
Yeah i think both are part of the problem. You need to develop something that can withstand those 100TW in an instant and you also need to re-direct that energy and store it.

you're going to get fuck all out of capturing sound energy
mark my fucking cock faggot

>>7991992
>The heat escapes to the surface at about 47 terawatts.
And why is my prof retarded? The heat that escapes is about the same as the heat that is generated by decay (he actually said that about 50-100% of this escaping heat is from the decay according to different estimates). Btw I wanted to reply that if we take more energy than what is produced then we'll cool he Earth down, but turns out it would take like 8 billion years to completely cool the Earth if we took an additional 40 terawatts, so we could do it for tens of millions of years before it would become noticeable.

It takes just a little less energy to create these solar panels than they will generate in their lifetime.

Pneumatic cars.

Powered by pure air.

Some locotomotives in energy plants still run on air because they're idle most of the time which makes diesel less economical.
Also no fumes.


The only problem is that for every day use like cars it's terribly inefficient.
It's only practical if the electrical energy source is clean.

Pneumatic-Combustion hybrids are nice but there's a lot of problems with patents and not a lot of investors for those who hold the patents.
