Submit interesting technologies that Tesla should use.

Submit interesting technologies that Tesla should use.

I did not find any similar topics here so i thought it would fit nicely here:

New technologies are found every day all over the world and i am sure not all technologies find their way to Tesla. So therefore this topic.

Here are 2 interesting ones i found today:


I hope you will share your technological findings here to for Tesla to investigate if they can use it in our future cars. To make our dreams come treu

Yet another trolling for proprietary technological insight thread.

What? Evil forces are trying to steal my suggestion for a return for analogue controls? All my wonderful ideas are available to anyone with cash. I can suggest a hollow tree nearby to make the drop in case you do not want to be identified. Tesla has the first option of course.

I've simply been in the ditches for far too long to the point where I see deception and subterfuge and IP infringement everywhere...I'll be alright one of these days.

Static Parking automation:
Considering some features I'd like to have in my Tesla which could be made possible via the sensors used for automated driving, I wonder if some 'static parking' features are (or could be) possible, such as:
1- Having the parked car sensing another cark parking in front of or behind it, and automatically moving either forwards or backwards by some inches to avoid being hit by the moving car (while of course avoiding hitting other parked cars) in case it comes dangerously close.
2- Similarly, the same car could detect a nearby car leaving it's parking space and slide 'out of the way' to let it get out more easily. It should then move back to a reasonable distance from remaining cars. We don't want our car to be stuck with no free room to leave the parking place...

I believe one VW implementation had the wheels rotate 90° ...

grayjohn1989 | 20 January, 2015

This is a invention i have thought about since i was 16 and never have shared it on the internet until now but because i want to see the electric car industry succeed i will now share it with tesla motors since your the leading electric car industry. if this technology works it would be nice to see some cash lol

here is my idea,
i planned on building a model of this invention but do not have the cash to do so.

i want to build a car that can recharge it's battery while it drives. what i plan to do is build a all electric vehicle that has a electric motor to propel it forward Then have two separate batteries to start the car off with and have a computer tell it when to change back and forth when the battery is getting low and then have a strong enough electric generator in the front or rear of the vehicle and if its all wheel drive have the electric generator in the middle. and after that is done i planned on connecting the electric generator to the propelling motor/motors to generate the energy lost back to the vehicle and have enough energy for electronics allowing the vehicle to never run out of energy therefore you would never have to recharge the battery.

if you have any questions email me

Brian H | 20 January, 2015

Stupid idea often suggested. All the rolling energy originates in the first battery, so getting a little back is just adding more drag and drain to it. Literally not worth the effort to even discuss.

Timo | 21 January, 2015

@grayjohn1989, read couple messages above yours to see why that doesn't work.

Grinnin'.VA | 21 January, 2015

Your "invention" is a conceptual perpetual motion machine.
Although many people have imagined such "perpetual motion machines", no one has yet make one that works. Furthermore, the very strong consensus among physicists is that such machines are theoretically impossible.

Please do some internet research on "perpetual motion machines" before you clutter the Tesla forums with suggestions that you have proven all of those theoretical physicists wrong.

lu_so01 | 7 April, 2015

Hi, today I’ve read that Tesla plans to introduce a “home” battery.
I would have interest in such a thing but it should do for me more. Because I’m living in an urban area the only charging option for me is solar panels . But that’s not enough (windmill would not be accepted by my neighbors)and I would have some ideas to make a better utilization, even make a business of it for better utilization of green energy. I would love to exchange a few words with someone from Tesla team.

Rocky_H | 7 April, 2015

@lu_so01, Tesla representatives don't participate in these forums, so if you want to get in touch with them, you would need to contact them through the contact form on their website.

Could Tesla incorporate microturbines in the suspension system to take advantage of the air pressure and generate electricity while the car is on the road...

Grinnin'.VA | 7 April, 2015

IMO, Tesla employs thousands of technically competent people, most likely including experts in every relevant field. Why do folks here presume that some web site that caught their attention has any content that Tesla isn't aware of?

I trust Tesla to sort out the technical issues and continue its cutting-edge innovations in BEV technology. They don't need our help for that. An endless series of suggestions from amateurs is merely a distraction.

Larry@SoCal | 7 April, 2015

Girnnin has it right, spot on. Trust Tesla, they are doing great!
Go go Tesla!

It's not appreciated to post links without description. As it happens, those are years-old news.

@ Enthusiast (January 3, 2013)

<< Tesla should tr to incorporate a generator into their their car : .... >>

The very first thing you learn about Tesla cars, and BEVs in general, is that, except for regenerative braking, on-board electric energy generation has been eliminated, because of the bulk, weight, noise, pollution, and risks it comports.

In exchange, you get a bunch of payload that you carry along in silence due to the energy stored in a space-saving battery that you replenish at low cost from the grid.

To try to bring back into the car some on-board energy generator is counterproductive and destructive of the general purpose of a BEV, except perhaps for the temporary use of a compact, quiet, chemical generator (like a Metal-Air "Battery") that you take along on occasion for a longer trip, unless you have enough Super Chargers on the way.

Otherwise, electric energy generation belongs with your home or your grid suppliers, no longer with your road vehicles, which have to maximize payload and comfort.

Timo | 19 April, 2015

Those shock absorbers would generate teeny weeny amount of energy. A tiny fraction of rolling losses. Would not make any difference, and added complexity could actually cause more losses.

For some heavy off-road vehicle they could make sense.

Palvaran | 20 April, 2015

Hey all, I am a diehard Tesla and Elon Musk fan as well and wanted to share some of the ideas that have been floating around in my head for about 20 years. Here are my top 5.

IDEA 1) Integrate an air compressor into all vehicles to monitor and self-inflate all tires.

The big 3 things that are touted as needing maintenance on a Tesla are tires, brakes, and windshield wipers. By adding a built in air compressor we can help reduce the need on 2 of those limitations.

A couple thoughts on tires:
•Biggest gains come from have properly inflated and pressured tires.
•Spare tires are beginning to become no longer included in about 20% of new vehicles. This trend will probably continue as it helps reduce weight which increases mileage. Consequently, some people are concerned about being stranded by not having a way to change it themselves.

The integration of an air compressor that can automatically channel air into a tire that is non calibrated or losing pressure allows the driver to know exactly what is going on. It tells the driver how long they have by calculating the rate of pressure loss versus the air compressor’s attempt at compensation.

IDEA 2) Remove the windshield wipers and replace them with compressed air nozzles.

In addition, by piggybacking off of idea 1 and reusing the same air compressor, please consider the removal of the windshield wipers form vehicles and replace their functionality via the air compressor. For example, inside airplanes, each passenger has a series of air nozzles above their head. Can we merely fit 3 or 4 to the front bottom of the windshield and thereby eliminate another component? This will help beneficial for the earth, less distraction from the driver, and at the same time require no replacement parts making the Tesla a more efficient design.

IDEA 3) Automatically lighten or darken windows via the same chemical that is used in optical eyeglasses ala Transition Lenses.

Luxottica is the largest manufacturer in the world for eyeglasses and frames at around 90% of the market. Potentially partner with them for use of their chemical component via the eyeglasses and apply to the windows of the vehicle.

Essentially, the hotter and brighter it becomes, the darker the windows gets. However, at night, it is clear and transparent thereby not affecting visibility at all. Working with Luxottica, apply a chemical limiter so that it cannot exceed the threshold for legalization in the least common denominator of markets. I.e. if 20% tint is the max, then the chemical agent would not allow it to darken past that amount.

IDEA 4) Replace the glass that is used in the vehicle with an acrylic or plexiglass solution that is lighter and more resistant to damage. The reduced weight would help improve fuel efficiency any further.

IDEA 5) Alter the construction of the aluminum, steel, and other metals so that it has hollow areas inside it ala a bird’s bones. This would allow the vehicle to remain strong, but reduce even further weight. Think of it like a steel girder that has holes drilled inside the middle, only in this case, the holes are not drilled through and are cast in a mold that allows it to appear to be a contiguous piece, but has empty pockets inside it.

Thanks Tesla, Elon, and other community members.


Grinnin'.VA | 20 April, 2015

OP: IMO it's rather inappropriate for you to suggest that this bunch of amateurs has any useful suggestions to make to Tesla's technology experts on which reported 'new breakthoughs' are worthy of Tesla's engineers' time.

Crowd sourcing this topic is a distraction.

james.nicklin | 20 April, 2015

Tweel. No more worry about flats or blow out ever.

wwl3m8 | 4 June, 2015

What if instead of charging battories you just go to a swapping station and change out the battery packs, and then tesla does what cell phone company's do and charge a subscription fee for renting them out older model batteries cheaper but lower range. no charge time just swap the batteries out and go, benefit is speeder time and a defect in the battery is an easier fix then changeing out an entire car. Just my thoughts

Brian H | 4 June, 2015

That's essentially what Tesla's swap plans suggest, though as an option or occasional choice for those prepared to pay to save time. But it requires lotsa stations and inventory even for that.

StarStuff | 5 June, 2015

I watched a TED Talks presentation showing a thin, flexible, solar panel. The inventor said it could be used to cover all of those glass windows on skyscrapers. I understand that Tesla has a sister company that produces solar panels for homes. I'm sure they have someone working on technology to add solar panels or coating to the auto itself in order to extend the distance it can be driven before charging. It reminds me of one of those post apocalyptic movies where people are driving around in old cars with bulky solar panels strapped to the hoods of their cars because there isn't any more gas. Science fiction will once again become science fact, only in a much more attractive way.

Brian H | 7 June, 2015

No. Even 100% of the car covered with 100% efficient panels would move a car only a few miles a day (<10), in bright sun. That's all the energy there is.

Rocky_H | 9 June, 2015

The rigid silicon solar panels have good energy efficiency, but aren't convenient to mount on things. Thin film solar panels are the opposite: convenient to mount, but worse energy efficiency, so they wouldn't contribute much energy on the scale of what the car consumes.

christianbaro | 9 November, 2015

Harsh winter is a big problem for electric cars so would it be possible to include some Tesla models with a small gasoline or diesel generators?
It would only be for emergency use and it would produce enough energy to drive home or wherever the charging station is.
Small size generator would fit in a small space and would make a huge diffrence in reability for countries with arctic conditions like winter in Finland.

Mike83 | 9 November, 2015

Traveling over 220 miles for the past two years at lower than 22 F(-6C) has not been an issue in my P85. Of course no speeding or racing.
Please NO ICE is needed.

JuJoo | 9 November, 2015

Tesla would never make any model a plug-in hybrid, even for emergency use. In addition, it's not so simple to just give it a gasoline generator; it would affect the entire drivetrain since it's a completely different technology.

Red Sage ca us | 9 November, 2015

One gallon of diesel fuel holds approximately 40.7 kWh of energy potential. The best diesel motors are perhaps 38% efficient. So they only output 15.466 kWh of work per gallon. Assuming energy consumption at 300 Wh per mile, that would be enough to drive 51.553~ miles per gallon in an electric vehicle powered by a diesel generator.

One gallon of gasoline fuel holds approximately 33.7 kWh of energy potential. The best hybrid gasoline motors are perhaps 36% efficient. So they only output 12.132 kWh of work per gallon. Assuming energy consumption at 300 Wh per mile, that would be enough to drive 40.44~ miles per gallon in an electric vehicle powered by a diesel generator.

A 90 kWh battery pack holds the approximate energy equivalent of 2.67 gallons of gasoline. The Tesla Model S 90D has an EPA rated range of 270 miles. Hence, there is a combined EPA fuel economy of 100 MPGe for it. Thus, there is no need for a range extender at all.

That's wrong perception, pretty much like the one that all electric cars are just glorified golf carts. Cold is not a problem for Tesla cars. You get less range, not so much because of cold, but because worse road conditions.

Heater does reduce range quite a bit though when it is properly cold outside. Seat and steering wheel heaters save quite a bit at that.

novozilov | 10 November, 2015

It would be nice if Tesla would offer portable generator mounted on a bumper or on a small trailer so you could go any where without looking for recharging station. Cyclon Power Technologies Inc (CYPW) has a good idea for a clean generator. You can use this generator in a blackout to power you house as well.

Timo | 10 November, 2015

Third post of the same. Flagging novozilov post.

EcLectric | 11 November, 2015

Hey, I got one!

Put a big 'digger' on the front of the car, and it will dig up the dirt/road in front of you and put it back behind you. Then you'll always be going downhill and won't need to recharge!

Take that Jules Verne!

Instead of taking something away, we should add something.

How about if it looks for those key words, and when you next log on, it takes you straight to Khan Academy or some other site for an instant physics lesson?

@ novozilov (November 10, 2015)

<< It would be nice if Tesla would offer portable generator ... >>

All you need is a Metal-Air DC generator and a DC frunk adapter for it (e.g., an Alcoa-Phinergy Al-Air "battery"). It's clean and quiet and you can keep it on a garage shelf indefinitely, if you don't need it for a road trip.

This can give you up to 1,000 miles of range extension.


Red Sage ca us | 29 November, 2015

Clean...? I do believe there is a rather nasty metallic sludge left over afterward... It may be recyclable, perhaps as part of a Lithium-Ion battery, but until then...? Nasty.
