Scientists found 200 E. coli strains, about half of which were resistant to at least one microbial agent, in manure, air, and horse nostrils at Polish riding centers. Here’s what that means for you.
If SpaceX gets a fully reusable Super Heavy Starship flying to orbit in 2020 and then has 100 fully reusable flights by 2023 then the cost of space will drop by 100 times. This will start fulfilling the plans for lunar bases, lunar mining, and space-based solar power.
If each Super Heavy Starship costs $300 million and has $1 million in operating and maintenance cost per flight then the per flight cost is $4 million. Super Heavy Starship is supposed to launch about 100 tons to orbit.
Assuming that 800 Starlink satellites are launched by April 2020, then SpaceX will start doubling its revenue from $2–3 billion to $5–6 billion in 2020 and ten billion in 2021. This will mean that SpaceX will be able to afford to build dozens of Super Heavy Starships.
Popeye would be proud.
Popeye uses spinach to power his muscles. Now, scientists are looking to spinach as a power source for making electricity.
A solar cell converts sunlight into electricity. Most of these, today, are made of a material called silicon. The new device instead uses proteins from spinach and from a bacterium called Rhodobacter sphaeroides.
We can do this by shrinking the size and mass of the spacecraft, allowing many to be launched together.
The Sprite is a tiny (3.5 by 3.5 centimeter) single-board spacecraft. It has a microcontroller, radio, and solar cells and is capable of carrying single-chip sensors, such as thermometers, magnetometers, gyroscopes, and accelerometers. To lower costs, Sprites are designed to be deployed hundreds at a time in low Earth orbit and to simultaneously communicate with a ground station receiver.
Year-round vegetables, minimal resources, climate-resistant—we’ve sung praises about vertical farms many times before. But Singapore’s Sky Greens is something very special.
There is a new battery type being hyped, with terms such as “Quantum Glass” battery or even “The Jesus Battery” and a claim that “It Will Ignite the Global $3 Trillion Electric Car Revolution.” Go and see it for yourself at investorplace.com (video transcript available from me), Forbes, and other financial information services.
This touted breakthrough in battery technology is the latest in a slew of innovative ideas that include “batteries made with sand,” “stretchable batteries,” “foam batteries,” “pee powered batteries,” “laser-made micro-super-capacitors” and more (13 Amazing Battery Innovations That Could Change The World).
