Talk:Energy harvesting

Bad Citation
Reference 16 does not say anything about piezo energy harvesting has been investigated only since the late 1990s, it is only an example of research  and is therefore not the correct citation for this fact. It should be changed.

Appalling use of English
This article was written by someone who doesn't use English as their first language, or a complete moron. It needs a complete clean-up. It really is bad!! — Preceding unsigned comment added by 94.193.68.7 (talk) 19:00, 24 June 2011 (UTC)

Current biomlechanical energy harvester
Max Donalson already has a working prototype to strap on the knee. perhaps it can be included

Electricity generating shoes
The electricity generating shoes + energy storage backpack could also be included see http://www.patentstorm.us/patents/6982497.html —Preceding unsigned comment added by 91.182.169.117 (talk) 18:18, 19 July 2009 (UTC)

No consensus to move. Vegaswikian (talk) 22:09, 17 October 2009 (UTC)

Energy harvesting → Human energy harvesting — To refer to energy harvesting of human power, perhaps the term human energy harvesting is more appropriate
 * The move was already done, but was reverted by User:GraYoshi2x, check the page histories —Preceding unsigned comment added by 81.245.90.148 (talk) 12:35, 9 October 2009 (UTC)


 * Oppose This article was changed after the Revision as of 03:19, 14 September 2009 to center on Human energy harvesting by adding that section and making everything else subordinate to it. That is not the intention of the article as it was written.  I reverted back to the earlier version.   GB fan  talk 14:48, 9 October 2009 (UTC)

RCA Airnergy Charger (in Electromagnetic energy harvesting)
Be very careful about claims made for this product. It is not clear that it can do what is claimed by the manufacturer, that is re-charge a Blackberry battery in about 90 minutes using energy from WiFi hotspots, as per the video taken at the CES show in this link: http://www.ohgizmo.com/2010/01/09/ces2010-rca-airnergy-charger-harvests-electricity-from-wifi/ Also see the follow-up comments in this link, as well as in the link cited in the article. It would appear that new laws of physics would be the bigger story if this device performs as billed. I have inserted somewhat cautionary text. Cheers, Psarj (talk) 18:50, 14 January 2010 (UTC)

You'd think that the fact that there is no company called RCA would be a dead giveaway that this is a hoax, even for those who have no understanding of the real world.

Really? You've never heard of [Radio Corporation of America|RCA]? Did a quick search, guess this gizmo never made it to market in any case. TANSTAAFL (talk) 20:57, 7 November 2011 (UTC)

Contradiction Tag ?
"In practice, for energy scavenging devices for wearable electronics, most devices generate just a few milliwatts of power. {Contradiction-inline|reason=With „a few µW/cm³“ (prior paragraph), generating a „a few milliwatts“ would require devices the size of several 1000 cm³ (=several litres)|date=November 2009}" (Posted by another editor). I've Googled the different terms in the cited source, and while a January 08 article for Vermeulen shows up along with NatuurWetenschap & Techniek, the article I found does not support the energy scavenging text. I've tagged the paragraph verify source, but perhaps the best thing to do is simply delete this rather obscure entry. But I'm not a technical expert, so some other editor should decide. --S.

Photovoltaic harvesting
In the Photovoltaic harvesting section, the explanation of DSSC working principle is wrong and the sentence doesn't even make sense in terms of syntax! To be addressed asap please! Lore Rove (talk) 11:50, 11 February 2013 (UTC)

harvesting energy from environment
Energy can be achieved from environment in many ways, but we always prefer when we utilize no any source and get energy freely. This fact is actually well adopted and related to Smart roads or piezoelectric roads in which electricity is produced from the motion of vehicle on the road. So i have added such type of thread in this article as it will surely improve the concept of energy harvesting  Nechlison (talk) 21:30, 7 January 2014 (UTC)

Information vs. advertisement
This article seems to include a lot of useful information. However, I get the impression that some people just add their own research to some sections intending to promote themselves. This leads to obviously wrong information. Just one example:

Arman Hajati and Sang-Gook Kim invented the Ultra Wide-Bandwidth micro-scale piezoelectric energy harvesting device by exploiting the nonlinear stiffness of a doubly clamped microelectromechanical systems (MEMSs) resonator. The stretching strain in a doubly clamped beam shows a nonlinear stiffness, which provides a passive feedback and results in amplitude-stiffened Duffing mode resonance.

This is obviously wrong. Anyone working in the field of nonlinear energy harvesting knows, that there has been a lot of research in this field long before the cited reference from 2011. Stanton, Ramlan, Cottone and may others have conducted research in the field of nonlinear devices since at least 2008. They included not only piezoelectric conversion, but also electromagnetic conversion.

There are a lot more "suspicious" citations of this kind. Consequently, I suggest that this article is completely reviewed! --77.2.13.97 (talk) 09:09, 1 February 2014 (UTC)

NoXCoO2
Perhaps that we should mention the use of NoXCoO2 to improve the efficiency of thermal energy scavengers ? See http://www.utwente.nl/mesaplus/archive/2014/3/343410/thermoelectric-materials-can-be-much-more-efficient KVDP (talk) 15:33, 25 October 2014 (UTC)

Magnetic induction
In this part energy harvesting by means of a ferromagnetic fluid is mentioned but the results are falsely presented, citing: "to harvest low frequency vibrational energy at 2.2 Hz with a power output of ~80 mW per g.[66]"

I just downloaded the cited article and there is no mention of a 2.2 Hz or 80mW/g, in fact the power is mentioned in the microwatt range. — Preceding unsigned comment added by David Blažević (talk • contribs) 11:15, 30 May 2018 (UTC)
