This is stupid. Ignores issue of where to get power for electric cars, and that a plant-based diet isn't healthy. https://t.co/AGZzNG3Xmv

It also assumes that the only potential future energy sources are solar or wind. Completely ignores nuclear.
There was an interesting conference in New York last week (that I would have liked to attend if it had been in my budget). It’s still hard to raise money for it, because modern philanthropists don’t know the history

Sorry, added missing link.
My friend Bob Poole (who has been advocating this for almost half a century) says it’s time to get it out of the sixties.
…is having quite a year. And it’s not half over. Yesterday, Elon implied in a tweet that FH could fly in late September or early October.
They seem to be trying to get a little more innovative, but they don’t seem to be in a big hurry about it:
Reusable lift-body launchers will be developed in three stages — rocket-engine partial reusable vehicle, rocket-engine full reusable vehicle and combined cycle-engine reusable vehicle, said Lu.
The Long March carrier rockets still have room for improvement, Lu said, adding that the CALT is developing a heavy-lift launch vehicle with a payload of 140 tonnes to low Earth orbit and 50 tonnes to lunar transfer orbit.
The heavy-lift carrier rocket is currently called the Long March-9, and it should be sent into space by 2030, he said.

Train for a while, maybe fly to ISS, maybe not, take jobs in industry to go to other planets. https://t.co/BwOmFKYvWg

Another demonstration of how fundamentally unserious we are about it, and what a fraud NASA’s #JourneyToMars is:
“Right now we are unconsciously setting ourselves up for a very difficult Mars program in the 2020s, because of all these immediate needs,” Casey Dreier, director of space policy at the Planetary Society, tells The Verge. “We don’t want to have a problem where we’ve prepared these samples and then they just rot on the ground because we’re unable to commit to bringing them back.”
Dreier argues that, above all, the most immediate need is the development of a new Mars telecommunications orbiter. Any future spacecraft we send to the Red Planet is going to need a way to communicate with mission teams on Earth. Right now, NASA has three operational satellites orbiting Mars, but only two — the Mars Reconnaissance Orbiter and Mars Odyssey — are primarily used for telecommunications. And these vehicles are getting old. Both orbiters have been at Mars for more than a decade and have lasted much longer than the span of their primary missions. By the time spacecraft are sent to retrieve samples from Mars, these satellites may have broken down and have stopped functioning. There are other orbiters circling Mars, operated by NASA and other space agencies, but these satellites are primarily aimed at doing science, and their orbits make them ill-suited for telecommunications, according to the Planetary Society.
But we have a giant rocket and a capsule in development that we don’t need to get to Mars, so we have that going for us.
This looks like a very useful development. I find this a strange attitude:
Let’s just remember that bilingual speakers are by definition fluent in two languages yet are too often deemed uneducated or undeserving of opportunity simply for sounding not quite like the people we see on TV.
As someone really only fluent in one language, I’m always impressed by people who are bi- or multi-lingual, even if they have an accent.
After several years, the documentary is finally out. Jeff Foust has a review.
I also remained on the cutting-room floor. It sounds like it’s a good history, but as Jeff notes, vague on what to fight for now.
Glenn Reynolds says they should practice what they preach, by government force if necessary:
First, we need to tax the “blue zones.” That is, we need to impose steep taxes on property in coastal areas that will be flooded by the sea-level increases that global warming is supposed to bring. By discouraging people from living or building there now, we’ll save ourselves from big problems in the future. Sure it’ll drive down property values, but those values should go down — they’re values for property that’s going to be flooded anyway, remember?
Second, we need to ban taxpayer-funded air travel to conferences. State legislatures could ban reimbursement for travel outside their states; Congress could require that no federal grant money be spent on air travel to conferences and similar events. A lot of academic conferences would fail, but that’s a small price to pay for saving the planet. And besides, it will encourage the development of Internet-based conference alternatives. A whole new industry might result: Green jobs!
Donald Trump can strengthen America by dumping Paris agreement: Sen. Inhofe
Third, we need to ban private jet travel. At first I thought about just taxing it heavily, but with the planet at stake, that might not be enough. It’s nice that John Travolta can have his own Boeing 707, or that Leonardo DiCaprio can jet around the world speaking against climate change, but the carbon emissions involved set a bad example that outweighs anything he might say. So no more private jets. Bigshots will just have to fly commercial like everyone else, the way they did in the 1950s. (And sorry, Leo, but massive yachts have to go, too). Politicians, too, should have to fly commercial. No more government-funded “executive jets” for them.Fourth, we need a luxury tax on mansions. Any home more than twice the size of the average American home should be taxed at 25% of its value per year. Celebrities and the rich enjoy great powers of persuasion — but with great power comes great responsibility, and they have a great responsibility to set a good example for the rest of us on climate change!
As he says, it seems like a modest proposal.
