Thank you for taking the time to read this. If you are a member of our SiliconJets community and have followed our account and posts throughout the past months and year since we began posting, you will know that our current group of tracked planes includes those controlled, owned or used by the likes of Elon Musk, Bill Gates, Mark Zuckerberg and more. That being said, our group has neither decreased or increased.

The team behind SiliconJets, over the previous month, however, has arrived at the point where we feel that now is the time for this to change.

With the recent surpassing of 1000 followers on our home service of mastodon, we cannot understate how grateful we are for the support our small community of followers has found in what we do with our emissions tracking, and has found our mission of public informational service to be of interest to them. Seeing as we continue to grow, we have reached a point now where we are faced with two related dilemmas: the prospect of growing our tracked list, and the ability to facilitate an expanded or maintained operation.

Increasingly, our infrastructure has proved to be at its limit in terms of its ability to support SiliconJets’ operation 24/7. It is for this reason alone that we have decided to start a Patreon for those who take particular interest in our work to support us in exchange for exclusive access to certain things and to have a larger say in SiliconJets’ future. The revenue generated from Patreon membership payments would go exclusively towards the cost of maintaining siliconJet’s infrastructure, and the rise in fees and costs that would be incurred by the addition of new aircraft to our tracked group. We have also divided our Patreon membership into tiers, where the highest paid tier has an absolute maximum of 10 members, whose fees would provide a good portion of the revenue needed for maintaining SiliconJets. Given this, Tier 3 supporters would be a closed inner circle in the SiliconJets community who, among other perks, would regularly have the opportunity to suggest, vote on and help pick the new aircraft we add to our group and eventually post public tracks and statistics of. Beyond this, they would have unrestricted access to our corpus of historical data, with every flight and its tracking/emissions data that we have tracked since SiliconJets’ inception, and upon its completion, access to our bespoke API with which to interact with our data.

There are also lower tiers which would give one access to our closed discord server, access to our historical data (with respective limitations) and access to exclusive events we hope to host in the near future. There is also a low tier with a small nominal fee for discord access, which we hope people will consider to join in on the fun in our server if they otherwise cannot support us at other tiers! Those who joined our early bird invited to discord on our socials over the past few weeks will remain with access without paying as a thank you for joining up early - their support in us setting up our discord server has been of much value to us!

We know that this is a big change, but we cannot stress enough that this is not a condition to SiliconJets’ existence for the sake of it. This has only been decided due to rising costs associated with maintenance and our wish that SiliconJets not only continue, but grow as much as possible in terms of our scope and to bring more people our mission to hold Silicon Valley big names to account for excessive private jet emissions.

We hope those of you who can will consider supporting us on Patreon as well as on Mastodon, Instagram, FaceBook or Twitter, and we cannot say thank you enough for 1000 followers on Mastodon.

We look forward to chatting with many of you directly for the first time in our discord server!

Our Mission

SiliconJets' mission is to hold the major players in Silicon Valley accountable for the hypocrisy of using private jets in an era where the public good has demanded that they act in a sustainable fashion.

Using public and open flight data available from Airplanes.live we monitor private jets which have been identified as owned by (or controlled by/attributed to) high profile figures particularly in the technology sector and report when they are on the move and emitting carbon dioxide (CO2).

How We Track

When a flight is live we update its status every 20 minutes using open flight data available from Airplanes.live and produce rough flight track maps using the static map tiles from OpenStreetMap using the Leaflet library. Prior to 1 April 2024 our flight data came from ADS-B Exchange.

We have an automated bot which monitors our selected flights and then makes reports every 20 minutes on our Mastodon account as well as on , and Instagram. We also posts weekly and monthly summaries.

How We Calculate Emissions

We calculate estimated emissions for the duration of flight which we have tracked. At the moment all the aircraft we track are variants of the Gulfstream G650 which produces an estimated 4825 kg (5 metric tonnes) of CO2 per hour of flight based on the emissions offset calculator from Paramount Business Jets. We are looking for indicative scale of emissions so there is no factor applied for take off/landing phases of flight when emissions might be higher.

We then compare this to an estimate of emissions of the same flight distance were made using standard commercial aviation services. We base this estimate on emissions estimates at Carbon Independent. This site provides a range of estimates of emissions from 180 kg if CO2 per passenger hour to 350 kg of CO2 per passenger hour. We have adopted 250 kg of CO2 per passenger hour for our estimates.
