Well this light is from burning a hydrocarbon fuel and some sodium from a renewable source IIRC. I guess sodium improves efficiency here too, but IIRC it was about a specific light frequency the 'solar cells' liked where they (that bit) is 60% efficient.

The issue with small capacity engines is that the combustion chamber surface area to cc (volume) ratio goes goes up dramatically as cc's decrease. What this means is that there is more surface area for heat to escape through, rather than push the piston the smaller you go. ie: Halving all the...

I'm well aware that wind energy might be converted into forward motion while in motion, or at least some torque in that direction. I posted about ...er... sprung wings over spokes likely helping to provide a bit of forward torque here somewhere. (They would ameliorate the effect of side...

How do you plan to legally get away with 4 wheels?

I would say that if you are looking for the ultimate burn anything engine a modern equivalent of these Lohmann Variable Compression Ignition Engines, with a Pyrolysis System (using waste exhaust heat and a bit of catalyst: zinc, copper) is the answer. You can pyrolyze just about anything...

Hmmm-ok! :) Some 26cc water cooled engines. 2-Stroke Engine Hobby RC Gas/Nitro Engines for Gasoline Boats & Watercraft for sale | eBay for many reasons (repairability, safety) I'd still use a chrome molly steel tube frame doing double duty as skin cooling and quarter wave silenced exhaust...

I hear ya. :) So the ideal diff as always, is a limited slip diff. As the pinion gears only rotate fast when one wheel loses traction; putting strong torquey generators on them would be ideal... But that adds a lot of weight and size for something hardly ever working..? Perhaps magnetizing the...

Got a link to that suspension? 20cc...? That's changed!? :) You were talking 5-6hp IIRC. The issue is at those cc's the surface area of the combustion chamber to cc ratio sucks and you lose a lot of efficiency to wasted heat. IIRC you're looking at ~7-8% at that cc vs 30% for a car sized...

Ah... so the INSIDE wheel thats turning slower is the one getting the power. Hmmm... no-thx: That is the wheel that will try and push you into going straight rather than turning in the direction you want to turn in. (That's especially dangerous for delta trikes) Putting generators on the...

Where do/did you find a small Limited Slip Diff suitable for quads? I like the price and ease of making this diff: but no LS..?

After your experience this is a moot point (for you) :), but 2 words: Tilting/Leaning Trike. Now you have: Legal..? (The main reason and lower rolling resistance) High Ride Height is no longer a stability issue = more visible and safer. The equivalent of a 2 wheeler, with around twice the...

So EV cars and trucks (Like Edison Motors' Topsy that will use the aircon to cool the battery when necessary) are all banging on the batteries way harder than the E-Bike crowd is? ie: You guys all run more than enough cells in parallel for heat=amps per cell not to be an issue, whereas; The...

Ah... Thx neptronix :)

This looks like it may be interesting/useful to battery case designers and builders? I've often wondered about the sealed battery boxes, with almost no mention of cooling, in most posts here..? Thermal Management System in Li-ion Battery using Air Cooling. (Blog by Aniket Bajare)
