Post your ideas.

My current one, Rain Gutter Pelton Turbine. It produces small amounts of electric to charge small batteries when ever it rains.

What are your ideas?

Helical VAWT. Wanted to build one for a while because I live in an apartment in a relatively high floor and I have frequent winds on my balcony but I didn't get around starting it yet.

Do you live in Britain? Because that's probably the only place in the world where this would be a practical powersource.

HOWEVER, there are more efficient ways of going about this, and there places in the world that are far rainier than Britain, like cooling towers.

Falling water droplet energy harvesting has been investigated for powering sensors inside cooling towers, which are for all intents and purposes, like a heavy rainstorm on the inside:

They've been able to generate a measly 10 mW, not quite enough to power a cellphone, but more than enough to power a sensor that sporadically reports temperature.

Last week when I put one of my wind turbines into the rain gutter flow, while it was raining it got 4volts 200mA (0.8 watts/800 milliwatts).

Passive solar for hot water in areas where freezing is a problem.

Bike powered generator. Of course, this would be hooked to a rectifier then a battery. You spin the flywheel to speed then engage the circuit. The massive flywheel simply allows you to keep a steady pace.

Hey now, as long as the waste is properly disposed of, nuclear power is very green, and very safe as well. The only time something will go wrong is if you build the reactor according to decades old designs that were never any good to begin with (Chernobyl), or go full retard and build it right on a fault line (Fukushima). Nuclear power really doesn't deserve all the bad press it gets.

Posting this here means that the solar water heater is not something common where you live, right?
It is logical considering that not all countries receive solar radiation of the same intensity but still for a few seconds it seemed weird that I saw this diagram here, like seeing a diagram of a spoon. :p
Interesting.
The inside of my water tank was made of glass and it broke a month ago :(

Well, no need to put it bluntly, but yeah, that's exactly it. Sure, the stuff has a fucklong half-life, but all that means is you have to think in the reeeeeeally long term. Disused mineshafts in geologically stable areas are perfect for this kind of thing. The earth provides natural radiation shielding, and the area isn't going to be disturbed at all. I remember watching a documentary about nuclear waste disposal one time and there was a site literally under the sea, right off the coast of Norway or somewhere like that. A big ol' cavern under the ocean floor. That's pretty much as out-of-sight as you can get.

Nuclear "fuel" is 95% reusable every year, 5% is waste. It is leagues ahead of coal as long as you live in a country with proper safety regulations.

And here I was, just trying to have some civil discourse. I guess that's too much to expect from /diy/. Sorry, I'll try harder to fit in

Help me /diy/, I got all these arduinos, what can I make with them? I was thinking of a railroad spike knife, but I don't know if that's steampunk enough to go with my cosplay costume. Maybe I'll just crochet some mead out of an old tube amp.

my personal opinion is that nuclear energy is the only mean of semi-green energy production capable of supplying the monstrous amount of energy that our civilised society needs. Yes, there are toxic waste and the possibility of a meltdown, but I am not entirely convinced that energy production from coil, gas or other hydrocarbons is safer and less dangerous in the long run. My hometown is next to a coal powerplant in rural greece, it's not that great.
It is also my opinion that renewable energy sources are not capable of supplying us with all the electricity we need, for now at least.
The solution to the energy problem is not a green (which is non existent btw) source of energy but reduction of the demand.

i think you would get better results using the wind turbine vs the rain gutter
unless it rains a good bit of every day

Just use free energies like wind, active/passive solar, micro-hydro, and mediator-free microbial fuel cells. Others that do pollute are biogas methane, algae, and animal.

For a rain gutter/waste water generator, would a standard water wheel be better than a Pelton wheel? I ask because unless your building is 50 feet high, the pressure won't be much for a Pelton, but you can get more torque with a standard water wheel that has little buckets to fill and push it around. With a pulley you can get a good bit of torque that way.

Passive solar heater made from aluminum cans (google that shit if you're not familiar); free heat in winter, and in the summer run that shit through a Stirling machine.

> waste water generator

Now that's an interesting idea!

While it wouldn't generate much electricity, a generator hooked up
to the black lines from the bathroom, kitchen and laundry (connected
to AGM batteries) would do more then a gutter generator, as the water
flow would be greater and happen far more often.

Only thing is, it would probably be a good idea to have some kinda
bypass on the bathroom black line, as while shaving and showering
would work fine, you wouldn't want feces gumming up your turbine
blades.

[Anonymous No.144529]

>>144509
I've done this before. It's better to not use the cans and instead use a piece of used metal roofing. the cans didn't have good passive air flow. If cans are needed to be used then I highly recommend simply smashing them flat (sideways, not from the top) and making them into a big flat piece of metal. This also saves tremendously on the amount of black paint used.

[Anonymous No.144546]

May i suggest an improvement to your design.

I've sketched it out; basically you wanna create pressure to facilitate faster turning of your spoonwheel. Do this by creating a funnel of some sort that will build up a water column. Obviously the hole in the funnel would be adjustable to accommodate various rain amounts

[Anonymous No.144551]

>>144546
That is in the design of the OP already.

Nuclear waste is 97% recyclable back into usable fuel. It can be recycled over and over again.

A lot of the leftover 3% can be harvested for medical or industrial use.

Reduce, reuse, recycle?

[Radiofag No.144569]

>>144403
92% to 97% is the figure I always see.

[Anonymous No.144590]

>>144546
Also, you want a solid column of water above the nozzle to create a head. In other words, your downspout should be completely full to generate maximum pressure at the nozzle when your turbine is operating.
Those conditions be difficult to maintain given the variability of the rainfall and the desire to maximize utilization. You may be better off with a reaction turbine rather than an impulse turbine.

I have plans to hook up a CD spindle tesla turbine modified to generate electricity onto the main water feed to the house. This way any time any water is used in the house you would generate some electricity.

Why bother gumming things up with the waste water?

[Anonymous No.144690]

>>144672
Well, with the incoming water, if it is water that is coming from a city location and not your own home water pump then you are onto something. However, if you are using your own home water pump from a well to get water then it defeats the purpose. In which case, it would be better to use a grey water turbine (black water is toilet water, fyi).

>>144672
> This way any time any water is used in the house you would generate some electricity.

That's a good idea!

Except I'm not particularly interested in knocking together a jury-rigged CD Tesla turbine
and noticed Amazon sells one that's claimed to produce up to 150 watts, ($400 though...)
which ought to work well for keeping a AGM battery bank powered up, for use in the event
of a power outage.

"Once again this Tesla turbine is eagerly awaited. Further improvements have been made after plenty of R&D
from the last turbine. The turbine efficiency has been increased by increasing nozzle pressures and added
shaped spacers that act like an impulse turbine AFTER the useful energy has be captured using the discs.
This may not be that satisfactory to some Tesla purists that don’t think that impulse turbine technology should
be mixed with the Tesla turbine but it does increase performance and they can be removed if required and
replaced with your own spacers/washers."

[Anonymous No.144972]

>>144948
Ah yes, I remember reading that. I was thinking that the spacers were probably baffled in such a way as to cup the water to make it impulse on its way out of the drain holes in the center.

I'll be doing this sometime. I have a stationary bike that doesn't have any proper resistance. I figured I'd hook it up to a motor and push some electrons in order to get resistance while charging a battery.

[Anonymous No.146061]

Imagine something like this hung from your gutter on a bearing and connected to a generator. This is about as effective a gutter turbine as you could get.
