well engineered motion into electricity device

[markdansie]

This is a well engineered product, they also raised over 3 million dollars crowd funding[/font][/size]
It is a bit expensive but has huge potential

Very interesting! Thanks for posting it.

Well, I suppose that I can play Darth Vader too just for the psychotic MIB agent role playing fun of it.

Pasting my posting on Revolution Green here:

It is interesting but don't count your chickens yet.  It doesn't make sense to put one on a truck because the energy it would harvest would come from the diesel fuel you put into the truck.  It's a fancy arrangement of clutches.  Making something like that cost-effective and seaworthy that will not need maintenance and will have a decent ROI is a huge challenge.  It will have to have moveable seals that have sea water splashing against the seals all the time.  I am no mechanical engineer so I can't say but that might be a challenge.  Notice there is no demo box driving a small incandescent light bulb because a load would slow down the flywheel and take all of the "fun" out of it.  I am smelling a very decent possibility that you are in Solar Freaking Roadways territory here. This is all pure gut feel.

Imagine a building on the seashore.  You have solar panels on the roof and a WITT wave power installation on the shore.  Which system gives you more bang for your buck?  Obviously this is an over simplified example but my nose is leading me towards the solar panel installation on the roof.  For example, the solar panel installation, just the installation costs, might be 1/100th the cost of the wave power installation if not more than that.  No moving parts vs. these big gyrating floats and huge gears and clutches and power couplings to generators, and on and on.  That sounds like very low maintenance vs. high maintenance and relatively low cost to relatively high cost to me (No matter what they are claiming about the low maintenance.)

This complicated gear is a nice technological achievement, but it is a very expensive precision device like a Swiss mechanical watch for 5000.-- Euros.

If something like this is put into seewater also the cable to shore will be a technological chalenge.

I like the alternative ideas http://www.witt-energy.com/future-applications.php more than the wave harvester. Like the mechanical watch that rewinds itself by the motion of the arm carrying it, such a device in a very small version could power a smart phone.

One should go for very small devices with a comperatively small output (e.g. 10 Milliwatt), but it will be an expensive thing like a Swiss mechanical watch.

Hi Conrad,

One of their videos shows a tennis ball sized device that is able to produce 4 Watts by human walking speeds:

Yes, precision machining and making the gear wheels have become very expensive, I wonder if the use of 3D printers  could reduce the costs somewhat.
