Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

2:40: "... the enormous health benefits of cycling ..." Yeah, but in a world free from internal combustion cars. I wrote here 12 years ago that I gave up cycling because of the diesel pollution in the city.

Seven new hydrogen stations will open by mid-2021 in California thanks to the collaboration between the Japanese gas company Iwatani and Toyota, the manufacturer of the Mirai: https://www.h2-view.com/story/iwatani-t ... alifornia/

Midipile: a pedal car 25 times less polluting than an electric model

Designed in a circular economy and 99% recyclable, the Midipile comes from Angoulême, and it does not intend to stop there.

(...) thanks to its concept of hybrid vehicle, a link between the electric bicycle and the small city car, carrying the great ambition to want to renew as virtuously as possible our modes of urban travel.

Pick up Midipile at 14:00 p.m. The idea was born during the first confinement in the mind of Bruno Found, an automotive engineer. Driven by the desire to "imagine the world after without carbon", man invented a velomobile (recumbent recumbent bike) with the uses of a small urban car. Thus, in the Midipile car, there is a pedal assembly as well as an electro-generator system which sends energy to the batteries on which the engine is based.

A motor, moreover reversible, capable of recovering kinetic energy to recharge the batteries. The roof of the Midipile is covered with photovoltaic panels also allowing it to be recharged when it is parked and providing it with up to 40 kilometers of additional daily autonomy. In numbers, the vehicle is expected to weigh 100 kilos and promises to reach 45 km / h in less than three seconds and can hold 170 kilometers between each charge.

Green and virtuous. Midipile is also a model of virtue in terms of design, being made of materials such as thermoplastic or even flax fiber, all of which are recoverable. Designed in a circular economy and 99% recyclable, the Midipile promises to divide by 25 the carbon emissions of an electric city car. The first prototype will be tested on the road at the end of the year and then quickly developed within a subscription rental formula at first.

I don't really see the usefulness of the lateral VPs. Risk of door knocking.
A 4-wheel vehicle on a cycle path?
The performance pedal> mechanical energy> generator> battery> motors> mechanical energy is likely to be lower than the proven system of VAE and more expensive in addition.
They had better study the proto well, otherwise it will stay in the boxes :P

You really didn't understand the point of the concept.

What a narrow-mindedness damn it!

The eBike was a good idea, here we reverse the concept and it is the muscular force that feeds the mess. Of course, on a hill, the engine helps the pilot, but on the flat the latter finds himself in perpetual hill! There is indeed a positive effect of regulation of the effort, but also a rather general increase of this one and the losses of output do not disappear by the magic of a mind, however large it is!
In short, muscle strength is too weak to serve as the basis for an ambitious propulsion system.

I don't think so, because if we are talking about hybridization, nothing would prevent us from pushing the concept further and imagining that direct traction by the crankset on the wheels is maintained, with electric assistance such as with a VAE ...

There would therefore be 2 modes to benefit from the two concepts, one identical to that of a VAE, and another taking advantage of a charging mode via pedal output> mechanical energy> generator> battery> motors> and restitution in mechanical energy, which would thus be triggered / triggered “on demand”, depending on the situation on the ground.

Since what we understand for the range, it is mainly the solar panels that accumulate current to recharge the batteries, and mainly also to make driving more comfortable in the event of a gradient. The muscular contributions to recharge the battery becoming secondary, so that the “cyclotomobilist” would manage the recharging via the crankset only according to its “shape”, and no longer “under permanent constraint” as on a conventional bicycle, this that would make a big difference! And since it is necessary to provide a technical solution to the practical problem, we could then imagine a system with a derailleur which would switch to recharge mode when it is desirable VS direct traction when it is required, or even (but it is more ambitious ) the addition of a heavy inertial flywheel (which would possibly contain the battery in its signature) and which would serve as an intermediary between muscular / electric traction VS recharging, and would also make it possible to dampen and regulate the high punctual demands required by the reality of the slope of the land.

This is what I would call intelligent hybridization. And it would not be the technical solutions that would be lacking to achieve this. For example, I find it superfluous to be able to start at 45km / h in 3 seconds. starting would be more judicious when pedaling because it affects the autonomy ...

So I maintain that it would be well worth “Keep an open mind” when you have this type of project in mind and you are looking for technical solutions to the practical problems posed (rather than condemning the concept prematurely). This type of vehicle does not lack a strong potential of various “margins of progress”, without a doubt ... One can very well imagine still, that the battery cap is (completely or partially) removable, and / or that you can also recharge it via a cable connected to solar panels located on the roof of your house (especially in winter when recharging by the only panels on the vehicle would be less efficient ...). There are plenty of things that still deserve to be conceptualized / optimized.
