From the link:
Interesting that with all the talk and hype about hybrids and electric cars, the low-tech environmental solution may still be the best. Proponents of plug-in hybrid vehicles spend tens of thousands of dollars modifying their vehicles to push the fuel economy into the triple-digit range. It's ironic that a developing nation can build a 164.5-mpg vehicle and sell if for less than the cost of a good set of car tires.
I wonder if it'll last longer than a set of tires... |

Also from the link...
"Styling is aggressive to evoke the speed and performance this little runabout can't provide."
It's actually pretty cool for the extremely budget minded. I wonder how far you could drive this bike for the price difference from the electric bike. Your neighbors wouldn't be as impressed with your greeness though. |

We sold CB100's and CB125's faster than we could uncrate them....back in the day it seemed that EVERY 15 or 16 year old wanted one. A good running CB125 would go 70+...tucked in, in a draft, down hill, with the wind...lol
Most of them came back in 6 months, to be traded in on a CB350  or in the back of a pickup...crashed out or otherwise hooliganized to death... |

Here is a list of 10 electric cars
Every car on that list is either a 6-figure purchase price exotic or a glorified golf cart. |

BTW - An instant way to reduce pollution and gasoline consumption by HALF is really simple - outlaw cars. Make everyone ride motorcycles. If it's cold - bundle the eff up. If it's snowing, get a damned Ural. |

Yay, my last post didn't get posted, must of gotten eaten when the server went down, and it is too much for me to retype, so I will just skip it.
Dave, do you have any details on this car? Hook a brotha up? Trade you my Blast?  |

Wifey would go for one of these:
"The CMT-380's microturbine features an electric generator and turbine components mounted on a single shaft supported by air bearings. Capstone microturbines operate at extremely high speeds of up to 96,000 rpm, resulting in a very high power-to-weight ratio. No liquids are needed to lubricate or cool the microturbine so little maintenance is required."

Here Frank I got no title for it though working on getting one.
I want to build one that goes faster its really easy to do actually |

"Speed: 25 mph"
Will they actually let you license that thing? You will wind up pissing off some of the bicycle traffic! |

Actually it will do 40 tops but its cool. I can also tell you to research charging stations and you will be enlightened on how a 5 year old can change a 400 lb battery pack should they need to. I understand the reasons for neah sayers but how fast was an early car the understanding of simple S-B conneters eludes some of the NO WAY it could work folks. I am now gonna build one I tried last year but had no time or money this year I will be succesful and maybe it can take a tour when its done. I have a PMC controller I have an accelerator switch and a motor. I have to figure some gearing problems I have a 12volt control set up and dual chargers 12v and 36volt with a 120 charger input. I will figure a power stearing system on the fly and a power brake solution which could prove a bit of a problem but I will overcome it. Heat is doable but no a/c will go in but there will be a fan and much less heat to deal with. I can put a small generator in it for emergancy charging I am gonna do it!!!!!!!!!!! |

No doubt it can be engineered that way. The problem is developing a standard that can allow for that 5 year old to do this on a wide variety of vehicles with standardized equipment.
For what it's worth, decades ago when I owned a '64 VW bug I looked into doing an electric conversion. Detailed plans were available back then and people made them work. It's much better today. It's just that is still remains beyond the ability to compete with conventional technology for the masses.
I wish you luck with your project and hope you enjoy what you are doing. I know it will be a project that will have you swearing and laughing and you will no doubt learn plenty along the way. I do support that.  |

a real simple explanation would be roller racks on left with charged batt, roller rack on right depleated car in the middle a simple steel or tube cage with locking pins on either side and rollers in the middle.
Pull up alaign shut dowm disconnect open pin on right side roll batt pack out onto rack of depleated batts lock pin. open left side pin roll full charged batt pack in lock pin connect and AAAWWWAAAAYYYY you go |

A/C is doable...there are new A/C systems on the market today in which the compressors are 36 or 48 volt ECM drive units that have remarkably low current draws...the trick would be to insulate the cabin so the BTU requirement would be low, which is also doable...power steering is no great hurdle...use an existing electric unit from a late model vehicle...or electrically drive a conventional pump...you could set it up for assist at low speeds only (where you need it most)...
There are also drive motors available that can be direct coupled to the axle without need of a clutch or transmission...either standard dc brush motors or brushless ECM's. |

Power steering? Man up and turn the wheel! We aren't talking about a '58 Buick. |

IThanks I know that there are many different systems as well but I am gonna stick with Curtiss as the parts are readily and easily available it is rather old technology but still quite effiecent. The power steering will by a secondary system from an electric forklift when shifter is engaged the pump will go on low draw continuous duty. I figure it 's gonna be a small rear whell drive car I can weld the drive motor brackets into the rear so it doesn't move with the suspension I gotta try to get a 3500 RPM motor with a good highway rear or maybe a old jeep but thats where I am gonna need help figuring the gearing and speed I need to be able to achieve 60MPH at leat. I can also incorprorate the turtle/rabbit or economy /power so you can select how you need to drive.
I will build a power pak of 3 12V deep cell marine batteries for starters see how lon I can get out of 1 batt pak |

Why not direct drive to the wheels? It's been done many times. No drive train loss or weight. |

Yes thats an option and a probability but to get both power and revs you need a happy rear I am an idiot when it comes to figuring speed to rpm's and my fat head is already full so it gets tougher to figure this stuff out as I get older I swear |

You have a target rpm using the drive train of about 3500 rpm at 60 mph. Assuming about a 3.7:1 final drive ratio...
3500 / 3.7 = 946
So just under 1000 rpm at 60 mph.
Adjust as necessary for the exact final drive ratio you have.
Or you can measure the circumference of the wheels and go from there... |

Yes, its called a Neghborhood Electic Vehicle, they can legally have a top speed about 30mph, but because of the low speed they don't need to comply with crash standards. So, glorified golf cart. |

We can figure out the gear ratio but we first need tire diameter.
This car formula assumes a 1:1 ratio between the tranny input and output shaft, so it's perfect to use for a direct drive unit.
Gear Ratio = (RPM * Tire diameter (inches)) / (MPH*336)
For example, let tire diameter = 12 in.
Then GR = (3500*12)/(60*336)
= 42000/20160
= 2.0833333333............
= 2.08
So with 12 inch tires, you need a 2.08 drive ratio to achieve 60 mph at 3500 rpm.
But the ratio is different depending on tire diameter, so you need your tire diameter in inches. |

Now this is interesting...
google ultracapacitors
Which reminds me, the UPS (Uninterruptable Power Supply) that the avionics test bench I worked on in the Navy relied upon for backup power did not use batteries, it used a huge bank of capacitors. It was the size of a small garden shed, but it would supply the power hungry bench with juice for upwards of 30 minutes. When I say power hungry, I mean the circuit breakers for each bay were 60 amps, three phase.
Ultracapacitors could solve the scarce element battery issue, which is the only real problem I see with the electric car. |
