some harmful emissions. then there's electric. but although batteries are getting far more efficient, the size that you'd need to power a passengerjet would be way too heavy. and there's one potential solution that's getting people really excited — hydrogen. hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use. that means that we need often very large, very heavy tanks, because they need very thick walls to deal with the incredibly high pressures we need them at. what you end up with is an aeroplane that can't have any passengers in.

up with new fuels. let's take a look at some of the options. there are biofuels, which are made out of things like plants or vegetable oils, but they still produce some harmful emissions. then there's electric. but although batteries are getting far more efficient, the size that you'd need to power a passengerjet would be way too heavy. and there's one potential solution that's getting people really excited — hydrogen. hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use. that means that we need often very large, very heavy tanks, because they need very thick walls to deal with the incredibly high
one of the main greenhouse gases causing climate change. the industry faces an enormous challenge to clean up its act, and that means coming up with new fuels. let's take a look at some of the options. there are biofuels, which are made out of things like plants or vegetable oils, but they still produce some harmful emissions. then there's electric. but although batteries are getting far more efficient, the size that you'd need to power a passengerjet would be way too heavy. and there's one potential solution that's getting people really excited — hydrogen. hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use.
really a surprise considering where she he's been up to this point how many democratic votes are expected here against this bill? is there a ballpark? i think it's hard to tell exactly how many democrats are going to vote against the israel bill. but one marker that we have is the discharge petition, the the fast-track process that democrats were trying to use to get the foreign aid bill to the floor. and the first place there were about maybe 15 keen to 20 democrats who did not sign onto that in the first place because of their objections to israel aid and the lack of conditions on so we could certainly expect to see that same group of members today voting against israel bill, if not more, now that it's clear that it has the votes to pass from both republican begins and democrats. >> let me ask about the ukraine bill that's expected to get a vote today. also expected to pass. if that passes, isn't a
