You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.85.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 21:48, 22 February 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

((About-distinguish-text|an automobile power source said to have been developed by Nikola Tesla|the unrelated vehicle manufacturers [[Tesla, Inc.]] and [[Nikola Corporation]]))

The '''Nikola Tesla electric car anecdote''' refers to a supposed invention described by Peter Savo, who claimed to be a nephew of [[Nikola Tesla]]. 

== Description ==
According to the story, in 1931, Tesla modified a [[Pierce-Arrow Motor Car Company|Pierce-Arrow]] car in [[Buffalo, New York]] by removing the gasoline engine and replacing it with a [[AC motor|brushless AC electric motor]]. The motor was purportedly powered by a "cosmic energy power receiver" contained in a box measuring 25 inches by 10 inches by 6 inches, which contained 12 radio [[Vacuum tube|vacuum tubes]] and was connected to a 6-foot-long antenna. The car was claimed to have been driven for about 50 miles at speeds of up to 90 mph over an eight-day period.<ref>((cite web |author=Robert Nelson |date= |title="Information about an Invention by Dr. Nikola Tesla, which is said to have harnessed Cosmic Energy" (Unidentified document circulated in the early 1980s) |url=http://www.rexresearch.com/feg/feg2.htm#tesla |accessdate=2010-11-27 |publisher=Rexresearch.com))</ref><ref>Ford, R.A., <u>Space Energy Receivers : Power from the wheelwork of nature</u>, Simplified Technology Service, Champaign, IL, 1993 "Information about an invention by Dr Nikola Tesla, which is said to have harnessed cosmic energy" pp. 31–37.</ref>

The story has been subject to debate due to the lack of physical evidence to confirm both the existence of the car and the fact that Tesla did not have a nephew named Peter Savo. Tesla's grand-nephew, William Terbo, has also dismissed the Tesla electric car story as a fabrication.((citation needed|date=March 2024))

A number of web pages exist that perpetuate this anecdote.<ref>((cite web |last1=Mathews |first1=Arthur |date=2013-01-29 |title=Tesla's Last Known Living Assistant's Recorded Statement |url=https://www.nuenergy.org/arthur-mathews-about-tesla/ |archiveurl=https://web.archive.org/web/20181116013246/https://www.nuenergy.org/arthur-mathews-about-tesla/ |archivedate=16 November 2018 |accessdate=14 July 2019 |website=NU Energy |publisher=NU Energy Staff |language=English |quote=A new, and improved, primary zinc battery capable of powering an electric vehicle for a range of 500 miles before easily and economically replacing its cathode (negative terminal) plates by the car's owner from a year's supply of fresh, new plates which could easily be stored within the trunk of the car. |ref=mathews))</ref><ref>((cite web |last1=Tesla |first1=Nikola |date=2013-01-29 |title=Nicola Tesla's View of the Future in Motive Power |url=https://www.nuenergy.org/teslas-letter-about-the-electric-car/ |archiveurl=https://web.archive.org/web/20181116013117/https://www.nuenergy.org/teslas-letter-about-the-electric-car/ |archivedate=16 November 2018 |accessdate=14 July 2019 |website=NU Energy |publisher=NU Energy Staff |language=English |quote=Tesla states that he made numerous statements in publications in regards to using electricity to power a car.

With the exception of these points, every other account of this purported demonstration automobile is based solely on the Peter Savo story with additional embellishments added by subsequent retellings.<ref>((cite web |date= |title=Tesla's Electric Car |url=http://www.teslasociety.ch/info/doc/Teslacar.pdf |accessdate=2010-11-27))</ref><ref>((cite web |date=2000-01-01 |title=Tesla's Electric Car |url=http://fuel-efficient-vehicles.org/tesla-flying-machine/Tesla-electric-car-1931.php |url-status=dead |archive-url=https://web.archive.org/web/20101113034000/http://fuel-efficient-vehicles.org/tesla-flying-machine/Tesla-electric-car-1931.php |archive-date=2010-11-13 |accessdate=2010-11-27 |publisher=Fuel-efficient-vehicles.org))</ref><ref>((cite web |author=Gary Lee Armijo says |date=2010-03-04 |title=Tesla's Electric Car |url=http://fuel-efficient-vehicles.org/energy-news/?page_id=952 |accessdate=2010-11-27 |publisher=Fuel-efficient-vehicles.org))</ref><ref>((cite web |date=2000-01-01 |title=Tesla's Electric Car |url=http://www.fevj.org/tesla-flying-machine/Tesla-electric-car-1931.php |accessdate=2010-11-27 |publisher=Fevj.org))</ref><ref>((cite web |date= |title=Nikola Tesla's 'Black Magic' Touring Car |url=http://www.evworld.com/article.cfm?storyid=1062 |accessdate=2010-11-27 |publisher=Evworld.com))</ref><ref>((cite web |date=1993-01-30 |title=The Electric Auto that almost triumphed, Power Source of '31 car still a mystery, by A.C.
