Andy. I have to agree with Jeremy, you want power density, then lead acid is the choice, traction batteries though heavy retain their integrity when heavy currents are demanded. Lithium, me not know enough about them, but I don't think they stand abuse. You have to weigh up the cost of batteries for...

Andy. I feel that you should slow down a lot, have a considered look at what your'e trying to achieve. I understand what your'e getting at with flywheel/s, however, Jeremy is quite right, let the batteries do the work. How are you going to power the flywheel/s ? You want high acceleration ? then you...

Hi Andy. Only this week I heard about the flywheel kinetic storage system for F1. This has been researched for many years, the bit I heard about was for buses, to give an initial acceleration boost from a standing start. The flywheel/s are brought up to speed from braking systems, those years the ma...

Interesting that we have only got 24 replies, so does this mean that we actually only have 24 paid up members on the forums and the rest of you are actually non paying members :lol: ChrisB Only just got here Chris, add another one to the vote. CW Says "If one cannot be bothered to cough up ÂÂ...

Hi Chris.

Logged on to-night, the forum is doing what it should do.

Good work, very pleased.

Hi there. Chains, great advantage is you can achieve wider ratios in one step, compared to HTD or other type toothed belt drives. HiVo or inverted tooth, MUST be run in oil, are expensive, and HiVo toothed gears must be mounted on very parallel shafts, they will not tolerate mis-alignment. Toothed b...

NT says "Any thoughts?" Yep - 1) You could attach small fan blade/s to the motor shaft. Power the motor with expensive PV cells and have a free ! to run electric fan. Probably never recover the cost of the PV cells though :-( 2) Drive the motor with a huge Savonius wind rotor charging a 12...

Just read this post.

Err, I thought that ONLY Airplanes were steered by foot control - Must be a flying bike !!!

Yes Chris. Deker is looking, but how can one help another when they can't be bothered to state their location when they sign up. Might seem silly to you, but I have contacts in other parts of the country who may be able to help. That is - if the enquirer is not close to me. That person could not eve...
