This personal utility drone, designed to be nearly silent, is programmed to hover an exact distance above your head at all times unless objects are in the way. The drone suspends a lightweight mirrored parabolic heater which has the ground beneath you as its focal point. This doubles as an umbrella
or sunshade while in cooling mode.
Perfect for skating or sitting in the stands at a hockey game or anywhere else you want your own personal space to be heated or shaded.
<Disclaimer>
Fry-co is not responsible for remaining stationary too long while ice fishing.

Did version 1.0 utilize a Fresnel lens? |
|
| |
It would be even more effective with a third bolic. |
|

Heat is provided by electrical resistance.
We tried microwaves but the nausea and second degree burn complaints of our subjects rapidly killed our funding.
As did the Fresnel lens tests. Polyester toques, jackets, and shoe laces were also dropped at this point in testing.
A third bolic? Is that a new type of steroid? |

I think he means if a pair of bollocks are sufficient for the task, imagine what a 3rd bollock could do for you! |

Description. A-Bolic is our most potent anabolic growth supplement designed by none other than True Nutrition co-founder Dante Trudel, and is intended for serious athletes only. This non hormonal muscle builder is for both men and women. |

Three aren't enough. We need to go hyperbolic. |
|
| |
Well how many bollocks is THAT? |
|
| |
Just two, but they're large, hairy AND clangy. This is accomplished through the use of ClangWire (tm) extra thick steel alloy wires and our patented Big Brass Sphere, complete with internal sound intensification system. |

Here's your problem, well, one of them. Take a good prosumer-grade drone like a DJI Maverick 3. It weighs <900g and has a 5000mAhr battery. That's a 4s battery, so 16V x 5A x 3600s =288,888 J of total energy. That give it a flight time of a surprisingly high 45 mins or so, on average it's burning 105 Joules per second, or 105W. Heat is expensive energetically. Space heaters in the US are typically as powerful as the outlets can handle, 1600W/1.6KW or so. Let's give our drone a 1kW heater. 1KW is 1000 Joules of energy per second. So your drone would be up there for less than 5 mins. That's all assuming that the heating equipment doesn't weigh anything. |

What you want is higher energy density. For that, good old fashioned oil-derived fuel. Fuels are typically 100-fold more energy dense than lithium batteries, but you burn them at half the efficiency of battery/motor pairs. The remainder of that energy is... heat! That's what you're looking to make! Even better, you already have 4 fans blowing air past the engine down toward you. |
|
| |
You will have the equivalent of a dirt bike engine at wide open throttle a couple of feet above your head, but that's only a downside for some people. |
|
| |
...we, we, gonflab it!
A dirigible suspends the parabolic heater so that the only noise is the orientation fans, and we tether it to your backpack which contains the heavy battery needed for more than a few minutes of heat.
A few servos on the dish to account for any drifting and we're in production. |
