Regenerative braking is not an original idea … HOWEVER …
Having an entire system of regenerative braking being implemented on vehicle wheels is original …. and not trivial.
What is important about ReWheel:
1. ReWheel regenerative braking can be added to ANY vehicle, independent of its power source, i.e. combustion engine vehicle or electrical engine vehicle.
2. ReWheel Regenerative Braking is Much More Efficient than the regenerative braking present now in electric vehicles. (a proof: electrical vehicles still require the use of traditional brakes for fast stops)
ReWheel, Inc holds two issued US patents. More patents are pending internationally.
This is the amount of Kinetic Energy gradually lost every time we use brakes to stop for a stop sign, stoplight, or during an emergency stop, or while going down a hill.
This energy is wasted on the destruction of brakes and on the production of heat thrown into the atmosphere.
Regenerative Braking – a term for the technology of capturing this energy within the system of a vehicle and reusing it for the following acceleration.
A wheel is what allows the moving of the carriage or vehicle.
The wheel was always the target of an outside force forcing the wheel rotation.
NEVER BEFORE THE WHEEL WAS ITS OWN ENGINE (even though at times) being able to conserve and accumulate energy during braking and then use it for propelling itself for future acceleration.
How much of annual CO2 production can be eliminated by ReWheel.
Breakthrough Energy Ventures (BEV), ($1B funds):
“To be eligible for BEV’s money, a startup needs to showcase a scientifically sound technology that has the potential to reduce annual global greenhouse-gas emissions by at least 500 million metric tons. Global emissions currently measure about 40 billion metric tons a year.”
“It has acknowledged that $1 billion is not that much to invest in the energy space. Consider, for example, the fact that the latest nuclear-fusion reactor being built has a price tag of $22 billion”
US emissions by sector (2017)
29% from transportation; 25% from electricity-generating powerplants
As per Bloomberg New Energy Finance (menu page: Automobiles) it is expected that in 2040 67% of all the World’s automobiles would still be powered by combustion engines.
From the expected by 2040 over 2 Billion automobiles (2 billion by 2030) more than 1.34 Billion automobiles then would be run by combustion engines.
A typical (passenger) vehicle emits about 4.6 metric tons of carbon dioxide per year.
Calculating the effect of ReWheel.
Which part of all the traffic is “stop and go” traffic?
The United States has 3.9 million miles of roadway, of which 3 million miles are rural roads. The Interstate System accounts for only 1.2% of total mileage but carries 23.8% of total travel.
From the above, It can then be approximated that the traffic in the US is 24 % on the Highways, 22% in the rural areas, and 54% in the cities.
Accounting for some degree of ‘Stop and Go’ traffic, is experienced on the Highways, as well as in the rural areas, we can safely estimate 60% of all the traffic to be ‘Stop and Go’ traffic.
It is reasonable to project that worldwide part of the “Stop and Go” traffic is at least 60% as well, knowing that most of the world, outside of several European countries, does not have a highway infrastructure like in the US.
The calculation of savings in Gasoline / Electricity is based on the following:
1. The power generated by an engine is proportional to the engine’s RPMs. (rotations per minute)
2. Each cycle of RPM is burning roughly the same amount of gas and generating roughly the same amount of CO2.
That is, the power provided by ReWheel reduces the necessity of additional power produced by an engine. That will reduce the necessary RPM’s, and in the same proportion it will reduce the production of CO2 and in the same proportion it will increase MPG (miles per gallon).
An adoption of ReWheel devices by 100% of all the World’s vehicles would reduce CO2 caused by Transportations by approximately 17%
While 17% is an average reduction in Pollution and Gasoline or Electricity usage, those reductions are counted as 28% in the cities – where the pollution is at its worst.
17% / 60% ( of Stop-And-Go traffic) = 28.3%
29% of 33.1 Billion Metric Tons of total CO2 emissions – the percentage caused by transportation – represents 9.6 Billion Metric Tons of CO2.
If all the 97% of World vehicles (those that are still combustion engine powered) would use ReWheel, the CO2 production reduction would be 17% of 9.6 Billion Metric Tons, which is 1.63 Billion Metric Tons of CO2.
That represents a 4.9% reduction in total world’s CO2 emissions from all sources.
Reduction in 500 Million Metric Tons of CO2 yearly (BEV challenge) would require ReWheel to be installed on 30% of those vehicles.
From the Intergovernmental Panel on Climate Change (IPCC) that came out on 08/09/2021: “Every tonne of CO₂ emissions adds to global warming”
Enabling by REWheel of only one combustion engine vehicle will reduce CO2 emissions by an average of 1.4 Metric Tonne of CO2/year.
(5 to 7 Metric tonnes of CO2/year) x (17% to 28% - depending on the travel conditions) = 0.85 to 1.96; averaging to 1.4 Metric Tonne of CO2/year )
