Hell yes! The "air-boat?" concept could work out very well if the motor spins fast enough to generate decent thrust from a propeller. No...

and you could adjust the propeller so that the motor runs at the sweet spot nearest the maximum power point of the solar cell.

Or, similarly, you might be able to avoid the superstructure/air-resistance necessary to support the lens, by instead pointing the solar...

How about a fresnel lens above the solar panel?

Pretty much all off-the-shelf converters will have capacitors inside so you need to really nail down what the rules actually mean and...

Reducing rolling resistance, air resistance, and the rotating mass of the wheels should also be considered. Possibly even with...

More human-sized example: 100kg weight lifted to 2 meter height is 2 kilojoules or 0.55 Wh. or about same amount of energy as...

With propane I just assume 50.3 MJ/kg = 13.97 kWh per kg or 6.34 kWh per lb. 7 lbs = 44.4 kWh 5.24 out / 43.8 in = 11.8% Both...

Just wrapped up a 50minute propane test on the duel-fuel Champion 8000w Model 100297 with Chargeverter set to 100a -...

Is that all extrapolated from their marketing numbers or have you measured for yourself? 6.667 (kWh generated) / 33.41 (kWh total...

Finally got into a position to do a gasoline test on my duel-fuel Champion 8000w Model 100297 -...

I run a tiny system that I am back here to figure out upgrading. I have lived off grid on 400 watts of panels and 215ah of lead acid...

Right now I’m at almost 8 days. 182 hours 38 minutes. I imagine at some point it will charge to full again soon depending on the...

Probably worth mentioning (at least for other folks that find this topic), power supplies like the ones for computers usually aren't...

Best way to change generator oil is with one of those hand pumped vacuum oil changers they sell in marine stores for sucking oil out of...

Sheesh. I've been around the block a few times but apparently not the right block. I dug a hole under my generator to put a catch bucket...

I really really hope you bought properly Matched & Batched cells with full reports showing the IR at the the test points. You do...

I get the "coasting" part. This is where my system is this time of the year. I'm getting enough charge to avoid generator use but not...

Haha, don't beat yourself up. Lots of folks talk about "days of autonomy" (i.e. total kWh ÷ kWh/day) which is what you're referring to...
