Statements from this episode (30)
Zipline delivers blood to half of Rwanda's transfusing facilities
“We deliver blood to about half of the transfusing facilities in Rwanda.”
Rwanda delivers 55,000 blood units annually, primarily for mothers and children
“Rwanda delivers about 55,000 units of blood a year. 50% of that is going toward moms right after giving birth, and 30% is going to our kids under the age of five who have anemia due to malaria.”
UPS funds and advises Zipline's national drone delivery network in Rwanda
“UPS is basically supporting the work that we're doing in Rwanda. So they've both been helping fund the work and then also been advising us in terms of actually creating a logistics network at national scale.”
Zipline's next hub puts all 11 million Rwandans 15 minutes from medicine
“This distribution center is serving about half of all the hospitals in Rwanda, and we are already planning a second distribution center, which will put every single one of the eleven million citizens within a 15 minute delivery of any essential medical product…”
Dixon: Skipping the PC era made China's tech ecosystem more sophisticated
“I think in China, they kind of skipped the PC era and went straight to the mobile phone era. By some assessments, that has made them more sophisticated without having these legacy technologies.”
UPS VP John Mena: Zipline's Rwanda operation generates commercial revenue
“For Keller, it's a real revenue producing operation. They're making, you know, some money on this.”
Mena: Vaccine absorption rate in parts of Africa is only 20-25%
“In some estimates, in some parts of Africa, that absorption rate, 20 to 25%. So only 20 to 25% of what gets into the country to be injected in patients is viable.”
UPS VP: Medical drone delivery will adopt in developed countries
“Because we think not only is this leapfrogging the road infrastructure In, in Africa and other parts of the less established world, but for the more established world, this becomes potentially a much better urgent delivery of urgent healthcare to patients that…”
Rinaudo: Rwandan drone regulation is as strict as US FAA rules
“But interestingly, the regulation there is just as strict as the regulation here in the US.”
Fixed-wing drones yield 20x range and 400x coverage versus quadcopters
“Building a fixed wing vehicle allows us to have about 20 times more range than a quadcopter, so instead of going five kilometers, we go a 150 kilometers, and when you have 20 times more range, that, that means you serve 400 times the service area.”
Centralized medical inventory is economically superior to stocking 6,000 hospitals
“There's many healthcare-related products that are extremely expensive to store, so you don't want to have Significant amounts of inventory in every hospital in the U.S., 6000 hospitals, you know, it's much more efficient to locate a smaller quantity of invento…”
Personalized medicines cannot be stocked in hospitals and require rapid delivery
“When you think about personalized medicine, medicine that's genetically specific to the person, as we go in this direction with these rare immunotherapies and things like this, You don't get to just like stock a hundred of them at the hospital. You basically h…”
Rinaudo: Zipline will focus on healthcare delivery long term
“You know, we're going to be focused on healthcare for a long time, just because I think that's where this is really needed.”
Mena: Regulators will base drone rules on life-saving medical uses
“And the regulatory environment is not going to build its use cases on that. They're going to build it on life-saving products.”
Zipline's autonomous Rwanda drone delivery operations are illegal in the US
“What we're doing in Rwanda is illegal in the US, unfortunately.”
Zipline's Rwanda center covers multiple refugee camps
“There are three or four refugee camps within range of the first distribution center we've set up.”
Zipline's first non-medical drone delivery will likely be livestock sperm
“The first thing we do that isn't medicine will probably be sperm.”
Rinaudo: Livestock sperm delivery boosts Rwandan family economic output 30-50%
“It turns out if you can get sperm to these farmers, you can increase the economic productivity of that family by like 30 to 50%, which is a huge deal.”
Zipline drone delivery costs less than motorcycles and is 20x faster
“Because it costs less than doing a similar delivery using a motorcycle. It's 20 times as fast, and it doesn't depend on roads.”
Zipline covers all costs in Rwanda and funds expansion from profits
“We are currently covering all the costs of the system with what we're doing in Rwanda, and we are going to be using money from that first distribution center to fund the second.”
Rinaudo: Perception of African business as charity will change
“This paradigm that if you're operating in Africa, you're doing charity or you're doing philanthropy is totally going to change.”
Rinaudo: Zipline operates within a 30 by 80 foot space
“You only need Something like 30 feet by 80 feet for both launch and landing.”
Rinaudo: Zipline drones can drop deliveries into two parking spaces
“So we can drop into about two parking spaces. So any driveway, as long as like a house had a driveway, we could deliver to that house.”
Rinaudo: Drones target suburban and rural logistics, not skyscrapers
“It's very efficient for UPS to drive a big brown truck up to the lobby of a skyscraper and unload it. Whereas We're a lot more focused on suburban and rural where it's less efficient.”
Rinaudo: Zipline drones use Tesla Model S battery cells
“Yeah, and we actually use the exact same cell that goes into the Tesla Model S.”
Zipline built jet-style drone flight computers at 1/1000th the cost
“The way we've done that is essentially we've looked at how flight computers in commercial jets are designed, and then we've built the same architecture just using cell phone components for one 1000th of the cost.”
Zipline launches an entirely new drone fleet every four to five months
“So right now we're, we are designing, manufacturing, and operating a completely new fleet of vehicles about every four or five months. That's new airframe, new avionics, new everything.”
