Arachne Aerospace

Now riding #thesuntrip2018 rally. #solarbike + #solarflight + free software. Formerly known as Arachne Labs.

I travelled from Lyon, France to Guangzhou, China in 106 days, using only solar energy and my human power. #thesuntrip2018 @TheSunTrip

@DanPriban @ZalozkazMoravy Tady jsme narazili na základní rozpor mezi liberálním a konzervativním pojetím společnosti. Liberál věří na dohodu, obchod, smír. Společnost je pro něj diskuze. Konzervativec chce vidět násilný výkon moci v akci, chce vidět hierarchii, chce aby všichni policii poslouchali...

[Arachne Aerospace @ArachneLabs]

Something is going on with the next #solarbike project for @TheSunTrip 2024... this time it will be true recumbent, but also even longer wheelbase than Lenochod 1...

[Arachne Aerospace @ArachneLabs]

Although this is not really setup for #solarbike rallye, it somehow suggests, that well known @TheSunTrip team "Hyundai elevators" of 2018 may face some serious challenge one day :-)) Followers of this timeline see the history unfurling :-)

Solar panel originally installed on my experimental #solarbike #cargobike made it all the way to the World of Freight, as part of more advanced model manufactured by "Cargobajkers" for Dachser... @TheSunTrip

"Přece nebudu ve 21. století méně topit!" volají mnozí.

Nevšimli jste si, že k výrobě energií,
používáme technologie 19. a 20. století a právě proto máme problém?

Kdybychom používali technologie 21. století, nejsme závislí na totalitním dodavateli hořlaviny vykutané ze země.

[Dan Priban @DanPriban]

Nepřijde mi úplně fér tvrdit, že za současné energetické problémy může plánovaný přechod na obnovitelné zdroje energie. Současný problém je naopak právě ten, že jsme na obnovitelné zdroje ještě nepřešli a právě proto s námi Rusko tak zametá.

Supercharging #solarbike - current solar output is around 120W, charger adds around 250W. Should be still relatively safe for the battery...

[Arachne Aerospace @ArachneLabs]

Lenochod 1.2 after upgrades at Dohalice forge. This is the possible #solarbike layout, with lot of shade for both my head and legs, battery and motor. The front view is excellent, while I also directly see where my front wheel goes...

[Arachne Aerospace @ArachneLabs]

Back in Dohalice workshop/forge. Banana for scale...

[Arachne Aerospace @ArachneLabs]

The solar panel of the #solarbike rear panel is not quite right on this video, but this will be fixed on Tuesday at Dohalice forge :-)

[Arachne Aerospace @ArachneLabs]

Record attempt this weekend was failure on so many levels, including need to recharge from public charger, punctured rear wheel and more. Performance of new panels is underwhelming, 50% of Wp, but basic #solarbike layout of panels is the best possible, combining shade and view.

[Arachne Aerospace @ArachneLabs]

Cheating - charging from public 230V charger (together with solar = supercharging :-) ). This means that the record attempt for this #solarbike has been given up: it is way too hot, for both solar panels and me. New panel setup is rideable, bud FV panels are not performing well.

[Arachne Aerospace @ArachneLabs]

New panel setup is rideable and provided much better front views than the old long roof setup #solarbike

[Arachne Aerospace @ArachneLabs]

#solarbike first 44 km from 220 km attempt

Lenochod 1.2 #solarbike record attempt - morning

@SwedeFred Front view issues

[Arachne Aerospace @ArachneLabs]

There was some #solarbike development today. Test ride is planned for today evening, tomorrow there will be 200 km ride attempt. Some upgrades of roof welding is planned until end of June and then there is plan to see how far I will get during 1st week in July.

[Lyon Capitale @lyoncap]

Le prologue de « Sun Trip » est parti de #Lyon le 15 juin (avec un départ officiel le 17 juin de Grenoble) : boucler 2500 km en vélo solaire via la Slovénie jusqu’à un retour à Lyon le 9 juillet.

[Arachne Aerospace @ArachneLabs]

This is 150W solar roof. There will be another 150W front panel. #solarbike
