    High Voltage versus High Current

    I'm almost afraid to ask... almost... I searched with several key words and tried to digest various threads, but I don't seem to be searching the right thing. If there are two motors putting out a given wattage. One gets there with high voltage (say 120V/10Amps) and the other with high...

    Project Soylent Green

    I've pretty much resigned myself to those A123 20AHr packs and have geared the front suspension box to hold and protect them. I needed more weight up front anyway. There's plenty enough room to hold about four times what I need for the range. And, yes, they'll be about twice the cost of...

    Project Soylent Green

    I wanted to give an update on Soylent Green. I’ve gone through a little research looking for a free/open source Finite Element Analysis program. I settled on Z88Aurora (http://www.z88.de/). Although, it is sponsored by what appears to be college professors and their graduate students at a...

    So, this is more Chinese marketing?

    Project Soylent Green

    I've just started looking at these LiFePO4 batteries. These ones that sun-thing28 sells... they use the little flat cells that look like freeze dried food. Aren't these the same cells they use in production cars? And if so, how come cars have all kinds of liquid cooling around them, yet he's...

    Project Soylent Green

    1. I've long punted lead based batteries of any type. 2. I next started looking at NiMH D cells as the next cheapest available. Doing reality checks on the Internet, was showing that 50C discharge rates are achieved with special batteries, but 20C seemed to be a realistic “norm”. Heck, my...

    Project Soylent Green

    I bought the suspension on eBay and it didn't come with any frame pieces. It was a rare find to find it with the brake calipers. They alone would have gone way over $100. Dauntless is correct about the frame anyway. On that model of ATV, the frame between the A-Arms is only about 6" wide...

    Project Soylent Green

    I hope it’s not a problem that I posted this on both the diyelectriccar.com and the endless-sphere.com. One forum seems to do things on a far larger scale and the other does smaller and lighter. I’m hoping that I can get constructive feedback from both camps. I think both have a lot to offer...

    Project Soylent Green

    I would like to introduce my project and goals. Soylent Green is a minimalistic commuter EV to be built relatively cheaply. I know it would be far easier to take a donor vehicle and convert it, but an important aspect of the project is my enjoyment of the design and building process and just...
