Microturbine

[Serg2000]

Hi ALL.

We would like to open a campaign to develop a microturbine for charging mobile phones

Like this one


What do we need to get started?

[Smokey]

Skills?

[Serg2000]

Electronics engineers, electricians engineers.
But it's not that.
We have the know-how.
We can order anyone to make a plastic structure and put it our know-how there.

[abeyer]

We have the know-how.

Then why are you here asking what you need?

[Serg2000]

We have the know-how.

Then why are you here asking what you need?

I didn't ask what was needed for this.
I asked what it would take to start a campaign.

Does anyone here have experience?

I actually bet this would be a decent place to find a DM for your D&D Campaign   Good luck!

[beanflying]

So many fantastic ways to market it like strap it to your e-bike but first make sure it has a flashing LED like this one Extra useful when you are carrying 10+kg of batteries too.....



Given the variability of 'wind' and in particular smooth stable wind from one direction without a decent length pole the idea while possible is impractical. There seems to be a 'new' idea to charge a widget every month that will be awesome, just remember if it kind of is someone was there first and will likely do it cheaper.

[Serg2000]

So we are the first with our know-how and it will be cheaper with us.
Just tell me where and what button to press to start the campaign.
Do u know that ?

you are joking, right?

[Serg2000]

No.
We never messed with this.
We don’t know where to start and wanted to hear the experience of someone who did it. How to do this better?
This is not the only project we have and we want to launch several.
Is this possible?

[Serg2000]

Yeah, it seems we to have figured out how to start.
The boss asked me to create a start page on Indiegogo for one of our projects.
Has anyone used this platform?
Can you give any useful advice?

1: Indiegogo is responsible for so many scams and unfulfilled 'products' over time with 'backers' (not customers because that is not guaranteed or even a requirement) left out of pocket.
2: The fact you are here in public asking how to go about it shows you are secondly fundamentally unqualified to execute 'the boss's request' and put your name to it.

Suggestion is find a job you are better qualified and have the skills to do.

Thanks for the answer.

1. Everyone is responsible.  Including the governments of the countries that spend your money.

2. I’m not asking how to do this, I’m asking for advice from those who have worked with this.
In the absence of advice, I’ll figure it out myself, faster than you.

Could you describle the energy flows of your solution with some few simple maths please ?

[Serg2000]

Could you describle the energy flows of your solution with some few simple maths please ?

I don't specialize in this, but it seems to me that everything is quite simple here

1. propeller with a diameter of 0.15 m and an area of 0.018 m^2

2. water speed 3 m/s

3. power 80 watts

4. for 10 hours 1 kWh

error 15%

enough ?

Whoops, we didn't know you were making a water turbine.    To efficiently extract energy from an unconstrained axial turbine in an incompressible fluid like water you need blades shaped like a boat propeller rather than an aeroplane propeller, and a lot more blade area relative to the swept area.

Also, immersed generators are problematic.  Maintaining a  watertight seal on a rotating shaft long-term, that will stand up to the abrasion of possibly silty water is *difficult*.   To avoid significant loss of energy, smooth flow over the generator body is desirable so it must be well streamlined.

Lastly 3m/s is nearly 11 km/h, a flow velocity that can typically only be found in mountain streams, rapids, and fast flowing floodwaters,  and it will typically be impractical or dangerous to camp close beside them while your USB device charges, and certainly not good for your phone to attempt to charge it in the splash zone!

[Serg2000]

They asked for math, I gave it.

3 m/s is much?
let's take 2.
power 24 watt
these are two 12 W LED bulbs
unlimited lighting for your campsite + smartphone charging during the day

Hydro is that you again?

[Coordonnée_chromatique]

They asked for math, I gave it.

Hello, a Pleton impeller would give a better efficiency even without injectors... but the real problem is the resistive torque of your generator, have you calculate it ?

[Serg2000]

why do you think so ? this is wrong.
but even if this is so, then what prevents us from using this Pleton Pelton impeller?

but the real problem is the resistive torque of your generator, have you calculate it ?

resistive torque depends on the power supplied by the generator. we know it, we don’t need anything else.
why do you need resistive torque? where do you want to use it?
do you understand well what you are talking about?

[Serg2000]

pardon ?

yes, we develop microturbine. hydro micro turbine

[Coordonnée_chromatique]

do you understand well what you are talking about?

No, i don't have this ability.

WTF?  Why are you going into technical details?  He said:

It's almost like you don't trust him!?  Just set up his Indigogo already!

[beanflying]

It was already setup the day before this thread was created. 

Technically the owner has the background to make this work in the hydrological sense. But with as far as I can see zero background in volume manufacturing 

The real question is why should this forum get used to assist in or promote an Indiegogo campaign given the terrible history of fail on that platform?
